The fastest and most powerful iPhone is here

Though Steve Jobs was not there, the new iPhone 3G (S) went on display at the Apple's World Wide Developers Conference in San Francisco on June 8. The 'S' stands for speed.

The new improved iPhone 3G (S) helps you download Web pages in a fraction of the time, and you can view email attachments faster.

Improved performance and updated 3D graphics deliver an incredible gaming experience, too.
The new phone can also capture video and boasts an improved capability for taking still pictures.
The iPhone 3G S will hit the market on June 19.

After a string of successes with the iPod and iPhone, Apple is hoping it can keep wowing shoppers with this latest version of its popular mobile handset. The iPhone 3GS will sport a number of upgrades from its predecessors – including a doubled capacity of 32GB; a digital compass; and the ability to record videos.

The larger memory will allow iPhone owners to store up to 7,000 songs or 40 hours of video on their handsets, which they can now download directly from the iTunes store.
Below is the summary of some of the features of this latest iPhone.

Video and 3-Megapixel camera:

You can shoot video, edit it, and share it - all on your iPhone 3G S. Shoot high-quality VGA video in portrait or landscape. Trim your footage by adjusting start and end points. Then share your video in an email.

The new 3-megapixel camera takes great still photos, too, thanks to built-in auto focus and a handy new feature that lets you tap the display to focus on anything (or anyone) you want.

Voice Control:

Voice Control recognises the names in your 'contacts' and knows the music on your iPod. So if you want to place a call or play a song, all you have to do is ask.

Compass:

With a built-in digital compass, iPhone 3G S can point the way. Use the new Compass app, or watch as it automatically reorients maps to match the direction you're facing.

Landscape keyboard, Cut, copy and past:

Report on 'Femtocell Applications Live' at Femtocells World Summit

I was at the Femtocells World Summit yesterday evening attending 'Femtocell Applications Live'. Everybody looked excited and the atmosphere looked charged with people full of energy. Earlier in the morning, Vodafone had announced that its launching first commercial European Femtocell network.

There were 12 companies showing their demo. Unfortunately I was not able to capture the complete details but here is summary of my understanding (and notes and photos).

Before we proceed further, I should also mention that Femto Forum launched Services Special Interest Group (SSIG) whose main task is to to develop a framework that will simplify the development and deployment of femtocell applications.

Demo 1: IP Access
IP Access showed couple of demo's. The first being Facebook Virtual Fridge Notes Applications and the other Femto-enabled Connected Home Applications. There was some problem with the microphone and also CDMA like interference problems (if someone in the room is shouting, everyone starts shouting and the noice level increase drowns out the useful info) so I diddnt catch the second demo very well.

The Facebook Virtual Fridge notes app demo was very interesting and I am sure that we will definitely be seeing apps like this soon. There is very good explanation on IP Access website here so I am not expanding on this.

Demo 2: Motorola

Motorola were showing their award winning Digital Picture Frame Femtocell. It combines the capabilities of a touch screen digital picture frame with femtocells and SIP soft phone. Their femto was CDMA based and are also known as CDMA 9100 series.

One of their demo was Video streaming on the mobile through femtocell where they demonstrated point to point video streaming by using electronic programming guide (EPG) and playing selectable videos in QCIF format with 5 to 15 frames per second.

Their other demo was to Demonstrate touch screen menu and features on femtocell. Here they showed user interaction capability.

Demo 3: Sagem

Surprisingly you may not find any Femtocell related info on the Sagem website but the friendly people from Sagem explained me all about their products. You can see the Joggler type device in the picture, its known as Tabbee and has been launched by Orange in France. You can read more about it here. Its known as My Home Screen internally by Sagem. There is a similar Dect device launched with Telstra in Australia, internally called as My Communication Center. Sagem is also Alcatel Lucent Partner in their Femtocell development. In the picture above you can see the big femtocell that is soon being launched and the small one in front is the next generation of the same device that is being tested right now.

Their demo included Mobile Presence where, when the mobile reaches the Femtozone, different actions are triggered. They also showed how to remotely control TV and other applications through mobile when Femtocells are present.

Demo 4: Ubiquisys, Intrinsyc, Mobica

Ubiquisys gave a demo with Intrinsyc. Keith Day from Ubiquisys made clear in the start that they do not make Apps hence they were doing a demo with others. Their first demo was Mobica Podcast Sync App where when you arrive in the Femtozone then this app downloads the latest podcasts and you can listen to them. Once setup, its fully automatic. Could be really useful for me. You can read the press release of this one here.

The Intrinsyc UX-Zone is for Android phones. Depending on the surrounding the theme (desktop of phone) changes. When you arrive at home, it will show new apps that were not visible earlier. You can read more about it here.

Demo 5: Pirelli

This was a complete new name for me as I have never heard of them before. Their website is here.

They were showing IMTV application. IMTV is IM + TV. Their demo showed two different homes having a Quad-Play bundle from their operator. With the help of 3G Femtocell and the set top boxes the two homes can interact via Instant Messaging (IM). It is also possible to share information like what one home is watching to other.

The set top boxes are designed with open API so some third party can develop apps using it.

Demo 6: Airvana

Airvana has been in leading position in Femtocells. I always see some of their Femtos being tested somewhere or the other.

They were also prodly showing off their products and the name of their partners as can be seen above and below

Their demonstration though not groundbreaking but was done very well. The concept was explained clearly and in a way that anyone can understand.

A scneario was created with the person doing demo saying that he has two daughters and whenver they enter the femtocell zone, he gets an SMS saying that they are home. If for example one of them gets their boyfriend then the person will get an alert as whenever a new user camps in the cell, he can monitor. He can also monitor the number of active users so if there is a party, he can find out. Maybe we should call them Femto Spy Apps ;).

You can also synchronise the Digital Picture frame to your mobile so that whenever the phone comes in the Femtozone, the pictures are uploaded to display automatically.

Demo 7: Alcatel-Lucent

Their Demo included a new location aware "Over the Top" (OTT) apps from Google Latitude, Geopepper, etc. This can also help in things like retail affinity and proximity marketing. Another demo was of Geo mag. A service that delivers e-mags when a user enters a Femtocell

Another demo was Home notes, a 21st century version of post-it notes, whereby you can text or e-mail your messages to a place delivered only when the user has entered the target femtocell. Somewhat similar to IP Access application mentioned above.

Demo 8: Huawei

Theirs was a simple demo of detection service. When a family member enters the femtozone, you will receive notification SMS. The other was that when the UE is in Femtozone, the handset will be updated with a list of latest services and can enjoy them with single click. By the way, their Femtocells are of different shapes which are quite interesting.

Demo 9: Thomson

They were showing Integration of a standard mobile handset (with no additional client software) into the home network and using the mobile as universal remote control connected via 3G. The mobile phone can be used to control home multimedia system in dlna environment

For handset as universal remote control, Keypad and display for an X.10 control application hosted by the Femto CPE in OSGi environment. They showed the phone switching a light in the house on and off remotely.

Demo 10: Softbank
There was a video demo showing how useful Femtocell can be in daily life. For example a person is leaving home but has forgotten to close windows, so he gets a notification just when he is locking the door. Also if some friend comes to your house while you are shopping outside, you do not have to rush back. You can remotely unlock your door for him.

Along with the demo's mentioned above, LG-Nortel was showing their WiMAX Femtocell solution.

Then there was Continuous Computing with Starent Networks and PicoChip demonstrating their successful Iuh Inter-operability.

And finally, I met heard about another company called Rakon. They make oscillators for femtocells. You can see their flyer here.

Challenges in the future 'Network of Networks'

Came across this paper from Dec. 2000 recently. Its interesting to see that even back then researchers were thinking about multiple networks that a user can have access to via handovers. Researchers nowadays think about how to access as many networks as possible simultaneously. I call is Multi-stream aggregation (MSA), some others call it Multi-RAT Carrier Aggregation (MCA) and so on.

If we look at the different access technologies, each has its own evolution in the coming years. Some of these are:

• Fixed/Terrestrial broadband: (A)DSL, Cable, Fiber
• Mobile Broadband: 3G, 4G and soon 5G
• Wireless Broadband: WiFi
• Laser communications
• LiFi or LED based communications
• High frequency sound based communications 

Then there could be a combination of multiple technologies working simultaneously. For example:

• Broadband Access via Integrated Terrestrial & Satellite Systems (BATS)
• LTE-U / LTE-LAA

And the handover has to be seamless between different access technologies. For example:

• Seamless handovers between cellular and WiFi and vice versa.

There has been an interest in moving on to higher frequencies. These bands can be used for access as well as backhaul. The same applies for most of the access technologies listed above which can work as a backhaul to enable other access technologies.

While planned networks would be commonplace, other topologies like mesh network will gain ground too. Device to device and direct communications will help create ad-hoc networks.

While the current networks are mostly stationary, mobile networks will also become common. Opportunity Driven Multiple Access (ODMA) or Multihop Cellular Networks (MCN) would help devices use other devices to reach their destination. Non-standardised proprietary solutions (for example Firechat) will become common too. Security, Privacy and Trust will play an important role here.

Satellite networks, the truly global connectivity providers will play an important role too. While backhauling the small cells on planes, trains and ships will be an important part of satellite networks, they may be used for access too. Oneweb plans to launch 900 micro satellites to provide high speed global connectivity. While communications at such high frequencies mean that small form factor devices like mobile cant receive the signals easily, connected cars could use the satellite connectivity very well.

Samsung has an idea to provide connectivity through 4,600 satellites to be able to transmit 200GB monthly to 5 Billion people worldwide. While this is very ambitious, its not the only innovative and challenging idea. I am sure we all now about the Google loon. Facebook on the other hand wants to use a solar powered drone (UAV) to offer free internet access services to users who cannot get online.

As I mentioned, security and privacy will be a big challenge for devices being able to connect to multiple access networks and other devices. An often overlooked challenge is the timing and sync between different networks. In an ideal world all these networks would be phase and time synchronised to each other so as not to cause interference but in reality this will be a challenging task, especially with ad-hoc and moing networks.



I will be giving a keynote at the ITSF 2015 in November at Edinburgh. This is a different type of conference that looks at Time and Synchronisation aspects in Telecoms. While I will be providing a generic overview on where the technologies are moving (continuing from my presentation in Phase ready conference), I am looking forward to hearing about these challenges and their solutions in this conference.

Andy Sutton (Principal Network Architect) and Martin Kingston (Principal Designer) with EE have shared some of their thought on this topic which is as follows and available to download here.

Tridgets and Trivergence

These terms (and ideas) have been pioneered by accenture:

"Trivergence" describes an emerging device architecture where the network is used to separate the physical device from its data and its controls.

But normal people don’t go around discussing architectures. For most people, a device is just a device – even if it depends on a global network, massive datacenters, and tons of software residing outside the device itself for its functionality.

For example, most reviews of Apple’s latest iPod focused on the touch screen, battery life, picture quality, and look and feel. But it is the "outside the box" elements that sync your music library, deliver Podcasts and movies, learn your preferences, and, in general, turn the iPhone into something far beyond an old fashioned "portable music player."

We need some way to communicate that these new devices are more than just devices. According to Webster, a "device" is "a piece of equipment or a mechanism designed to serve a special purpose or perform a special function." Triverged devices are not a "piece of equipment" – they are one piece of a complex system brought together by a network.

To get this idea across, we need to say it in a word rather than a sentence. And I have a suggestion for that word: "Tridget."

These terms came to my attention from an article in telecoms.com which contains Interview with Andy Zimmerman, head of Accenture Global Communications. Summary of important point from that as follows:

"They're trying to imitate the Apple model, not only with the UI but also the services behind it. Right now, I feel like there is a device renaissance going on, where the device vendors are the ones that are attracting the imagination and attention of the consumers and, frankly, the carriers are not really doing that."

##
Ultimately, Zimmerman believes that no one sector - be it the vendors, the internet players, the carriers - will truly be able to dominate the others. The inter-dependency is too great, he says. That said, he feels the device players have the upper hand because, "so much of the user experience around mobile tends to be hardware related."
If the carrier community has a job ahead of it, he says, it is to learn to be comfortable with its unique attributes and to learn to effectively exploit them. Operators have assets relating to the end user - like presence, identification, authorisation and credit information - that give them a richer customer relationship than other members of the value chain, says Zimmerman. "But they haven't been particularly proactive about bringing those to the table," he says.

"I have a feeling that the carriers don't appreciate what they could provide that could be enabling for a lot of different kinds of service providers. Maybe they should be thinking about getting a dollar from every ten dollar transaction, rather than getting the whole ten dollars..."

##
Zimmerman talks about 'Tridgets', a "combination of content, device and the software that is used to manage the service." A mobile phone is a tridget, as is an iPod. So to is a wifi-enabled pacemaker, implanted next to somebody's heart. "In 20 years there could be a trillion tridgets in the world to be managed, all of which will be network enabled, and almost all of them mobile," he says. "If you can get a dollar a year out of each one, in terms of some information or service around the network to enable it, that's $1tn, which is the size of the current telecommunications industry."

##
Despite this, he argues that there is a rough 50/50 split in the carrier community today, with one half ready to accept a redefined role, and the other convinced that it needs to play end-to-end to avoid being marginalised. "It depends on the individual personalities, and where their company is at the moment," he says. "There are a fair number of executives out there who say that they're never going to be in the [end-to-end] business, and that they should focus on the enabling business."

These are the players that are positioning themselves effectively and pragmatically, he suggests

##
"My sense is there's still some room for consolidation among around software and among second tier vendors. Cisco has done a tremendous job in terms of M&A but they have a particular focus on emerging tech and much smaller companies. It's interesting that they have chosen not to do a big merger, even when there have been assets out there which, when you look at the relative valuation, would have been easy for them to pick up."

##
At the Mobile World Congress, Vodafone CEO Arun Sarin made a plea for consolidation in the handset operating system space, arguing that there are too many options to allow for the creation of an ecosystem in which interoperability and universal application development thrive. Zimmerman is no more optimistic about the chances here:
"With smartphones, there's so much still to be determined in terms of who's going to dominate. So I can't see the leading players gravitating around particular standards to help world hunger, as it were, if they think there is still a chance of picking up market share with their own products. The dynamic right now is not quite right for that sort of thing."

You can also read his article in MWC here. A very interesting point from that:

But the Tridget opportunity is too large to be dominated by any one company. David Clark, one of the architects of the original Internet and now a professor at MIT, has predicted a trillion networked devices in 15 to 20 years. A trillion is a very large number and it implies that Dr. Clark expects almost all electric devices – maybe even down to light bulbs – will evolve into Tridgets.

'The Future Inter-connected Network' and Timing, Frequency & Phase requirements

I had the pleasure of doing a keynote at PhaseReady 2015 in London today. My presentation is embedded below along with some comments, followed by tweets some of which I think are important to think about. Finally, I have embedded a video by EE and Light Reading which was quoted and maybe its important in the context of this event.

The Future Inter-connected Network from Zahid Ghadialy

My main focus during this presentation has been on how the networks have evolved from 3G days with the main focus (unconsciously) on speeds. While the networks are evolving, they are also getting more complex. The future ecosystem will consist of many Inter-connected (and in many cases inter-operable) networks that will work out the requirements in different situations and adapt to the necessary network(technology) accordingly.

An example of today's networks are like driving a manual car where we have to change gears depending on the traffic, speed required and fuel efficiency. Automatic cars are supposed to optimise this and achieve the best in all different cases. The future inter-connected networks should achieve the best based on the requirements in all different scenarios.

While it is easy to say this in theory, the practical networks will have many challenges to solve, including business and/or technical. The theme of the conference was timing, frequency and phase synchronisation. There are already challenges around them today, with the advanced LTE-A features. These challenges are only going to get bigger.

The following are the tweets from the day:

Finally, here is the link to video referred to in the last tweet. Its from last year but well worth listening.

What actually are Smartphones?

Mobile industry is these days ruled by the word Smartphones. There is no doubt that 2008 was the year of the smartphone. The last 12 months has seen the launch of iconic devices such as the iPhone 3G, Google G1, Blackberry Storm and Nokia N97. Smartphones are by every means driving the mobile market.

I come across this term almost everyday and thought how actually we define a Smartphone or What is a Smartphone?

The word “Smartphone” is a newly minted term that is used to describe a Telephone-capable device that also provides information and data organization capabilities. They are similar in size, shape, and usage to normal cell phone but feature more extensive data organization software and web abilities. Smartphones are equipped with complete operating systems that determine what kinds of functions and applications are available for that device. They provide a convenient way to carry several hand-held digital devices in one body. They provide the data and contact organization of a PDA, connectivity of a cellular phone, along with advanced multimedia like access to email and can in most cases support web browsing.

What Can a Smartphone Do? Unlike traditional cell phones that restrict a user to the applications and features that are originally designed for and then fixed into the phone, Smartphones allow for significant user-customization. These full-fledged operating systems (of which there are several options to choose from) allow a user to customize, install, and configure applications to suit their individual needs. Along with the prerequisite phone capability, Smartphones typically perform all sorts of important and useful tasks.

Smartphones are very smart in personal Information Management (PIM): PIM is a whole category of software functions that organize personal information. A typical PIM suite includes a scheduler for events, and address book for contacts, and to-do list. PIM can also include email, text notes, voice notes, and alarms / reminders.

Syncing with Desktop and Laptop PCs: Many Smartphones are designed to communicate with full-fledged PCs. Aside from just being cool, this feature allows users to easily install, remove, change and configure the software that they choose to equip their Smartphone with. It also allows further synchronization with PIM software both on your phone and on your PC.

Instant Messaging (IM): Not every phone that provides IM capability is a smart phone. But almost every Smartphone has a keyboard that at least allows access to every letter of the alphabet for sending Text messages. Some Smartphones have a key for every letter; others designate several letters per key. Word recognition software and other smart features further improve the speed and accuracy of Text messaging on these kinds of phones.

Email Access: While there are plenty of non-Smartphones that provide internet and email access, this option is more complete (and configurable) on Smartphone devices. You can sync email with your PIM software both on your phone and on your PC, send, read, and organize email, all from your phone. In most cases, you won’t even need to be near a wireless hotspot, either.

Web Browsing: All Smartphones allow for some form of Internet access. Wireless Network Protocols, or the technique in which web information is sent and received over cellular networks, are grouped into different generations.

But the question which remains albeit is what Makes a Smartphone Smart?

Smartphones are capable of so many features normally reserved for the realms of PCs and powerful PDA devices because they are almost PCs and PDAs themselves. There are typically two schools of thought used when designing a Smartphone: Create a PDA with Telephone capabilities, or a Telephone with PDA capabilities. No matter what design elements went into Smartphones developmental stages, there are still two things that set these mobile wonders apart from their regular cellphone cousins.

As mentioned above a Smartphone differs from a regular phone in that it has a processor running inside it, much like a computer does. These processors are currently nowhere near the power of PCs, but with the advent and subsequent redesign of Ultra Portable PCs (sometimes called Micro PCs), we are sure to see great leaps in Smartphone speeds in the future. Current Smartphones commonly use ARM processors; a power-efficient design used in other devices like routers, printers, and advanced MP3 players. A Smartphone processor is aided by computer chips that help perform certain tasks. A Smartphone equipped with a Digital Camera has an Image Processing Sensor inside it, much like a regular digital camera. Features like Playing Digital Music, complex web browsing, and other such access smart functions are all made possible by these computer chips.

If Smartphones have Operating Systems (OS), then it stands to reason that they also have software applications, as well. Applications that are written for a specific Smartphone platform (Platform is a fancy reference to the OS) can run on a Smartphone with that particular platform, regardless of what manufacturer produces the phone.

Based on the above discussion there is no doubt the most important software on a Smartphone is the Operating System. This is because nothing will work without it. A Smartphone operating system manages the hardware and software on the device. Some OS cover the entire access Software Stack while others only provide the lower levels like the Kernel and Middleware. These OS versions rely on third party software platforms to provide User Interface Frameworks.There are several different Operating Systems available for Smartphones. Some are designed for manufacturer-specific Smartphones, others are open and can be used on any Smartphone that meets the minimum requirements. Following are some of the OS for the Smartphones.

• Symbian OS: Symbian OS is used in over 100 different makes and models of Smartphone. This Operating System contains only the Kernel and Middleware parts of its software stack. This means that users of the Symbian OS will rely upon other software platforms for the AEE and User Interface Frameworks. This allows significant customization by both Wireless retailers and consumers.
• Linux OS: There is something special about Linux. It is developed and written by the developer community rather than by a single company. This allows for maximum creativity and innovation for developers and those software-savvy consumers, but has one major drawback: it means that software, updates, and other applications written for Linux operating systems differ greatly from each other. This reduces compatibility, and thus originally caused developers to avoid Linux. That is now changing, but many Smartphone manufacturers prefer to stick with more universally accepted OS software.
• Windows Mobile: This is one of the few Smartphone OS that envelops the entire Software Stack. Much of the strengths of Windows mobile lie in its completeness and full compatibility with other Windows based systems.
• Java and Garnet OS

Rich Communication Suite (RCS)

I have heard quite a bit about Rich Communication Suite (RCS) recently. It was supposed to start become popular by 2011 but Infonetics puts it as a little too late to become mass market anytime soon in a recent report. The new report forecasts that there would be around 6.8 million RCS subscribers worldwide by end of 2012.

Dean Bubley from Disruptive Wireless released a report some months back saying that RCS is a bit too late and inflexible and the built-in assumptions have problems which wont make it a mass market technology.

Anyway, I decided to explore the technology a bit to understand it better. Before we start digging into this, the following Youtube Video gives a good overview of what RCS is supposed to be:

The following article gives a good summary of RCS as of now:

The GSMA is welcoming a new version of Rich Communication Suite (RCS) that will enable mobile phone customers to use instant messaging (IM), live video sharing and file transfer across any device on any network operator. Deutsche Telekom, Orange, Telecom Italia, Telefonica and Vodafone intend to commercially launch RCS across several European markets from late 2011, and additional operators are expected to launch later in 2012.

Once adopted, Rich Communication Suite – e* (RCS-e) will enable customers to use these enhanced communication services across mobile networks in a simpler and more intuitive way. It is based on a specification put forward by Bharti, Deutsche Telekom, Orange, Orascom Telecom, SK Telecom, Telecom Italia, Telefonica, Telenor and Vodafone which aims to lower the hurdle and speed up the market introduction and adoption of these services.

With RCS-e, customers will be able to use IM, share live video and share files such as photos simultaneously during calls, regardless of the network or device used. RCS-e will enable users to communicate in a very natural way, much like with GSM voice and text today, and will also offer the simplicity and security customers expect from mobile operator services.

As customers open their address book, they will be able to see which communication services are available to them. They can then choose their preferred communications option. For example, a customer would see if their contact is in an area with 3G coverage and is able to receive video.

The participating operators will work with handset suppliers to ensure the service is integrated into the address books of devices, so that customers will not have to download any additional software or technically configure their handsets in order to benefit from the enhanced experience.

“Mobile operators are committed to giving their customers greater choice in the way they communicate with one and other,” said Rob Conway, CEO and Member of the Board of the GSMA. “We welcome the pragmatic approach taken by these operators to accelerate the commercialisation of RCS and simplify the experience for mobile customers and we will work to adopt this specification within the RCS initiative.”

The RCS specification is designed to be interoperable between all operators and devices, giving customers greater choice in how they communicate. The new RCS-e is the result of extensive trials and is a subset of the current RCS 2.0 standard with enhancements. It is focused on extending the principles of voice and SMS calls to deliver an advanced set of interoperable data-centric communications services.

* RCS-e is a new enhanced version of the RCS specification which is based on the use across networks of IP Multimedia Subsystem (IMS) technology, an architectural framework for delivering Internet Protocol (IP) multimedia services.

The following presentation provides a bit more detail

Eduardo Martin's blog provides some more insight into the RCS Releases:

RCS has 3 releases, each upgrades the previous one. I will focus on SIP Presence only, but RCS touches more than SIP Presence, it also works other services such as IM.

RCS Release 1 evolves around the concept of the Enhanced Address Book (EAB), an evolution of the usual address book. In short the address book is decorated with enriched information, coming from different services. This plays nicely with today's wishes for cloud stored information, unified social networks status updates, contact content such as portrait icons. I'm not going into technical details, but I for sure am someone who is aware of the design issues around SIP Presence, its hard time scaling due to huge traffic, the dozens of ugly workarounds to make it work, and RCS is a nice step forward into the right direction, there are simple decisions that deeply simplify the network design, making it more like "old" presence networks, which simply work. One remark, it takes quite an effort to define this endorsing IMS and OMA, 27 pages of functional description, plus 39 of technical realization, it should be a lesson for everyone in these standard bodies when defining more extensions or new versions.

The RCS Release 2 effort focuses on enabling access to rich communication services from a wider range of devices. In short it tells that the user has multiple devices, for instance a mobile phone and a PC, possibly concurring for services, and adapts Release 1 for that. It also introduces the Network Address Book, which is just the realization that the EAB needs to be in the network and sync the multiple user devices.

The RCS Release 3 mostly consolidates Release 2 features, and adds some minor enhancements, such as preparing the network for different usages of it, for instance users with devices, which are not connected to mobile network, instead only have broadband connections. In my humble opinion a very important and positive decision, it's about time to consider these scenarios and find out new opportunities. It is weird to say this, but the fact that the industry finally acknowledges that content sharing between two users may happen off the voice/video session is a victory, welcome to the world not session centric.

The RCS specs are available here.
