Some interesting April Fools' Day 2014 Technology Jokes

Its very interesting to see all the companies proposing very interesting concepts on the 1st of April. I was told that not everyone knows what April Fools day means so here is the link to Wikipedia.

Samsung Fly-Fi: Samsung has come up with some interesting ideas, the first being Wi-Fi for everyone powered by Pigeons. They have a website here with Video.

Power of Pigeons


Looks like since we have Pigeons everywhere, so they are always used in one way or the other. The best prank ever in my opinion was the PigeonRank by Google, back in 2002. I spent a few hours that day trying to figure out how they were actually doing it.

Smart Wear was always going to be the big thing. Quite a few smart wearables this year.

Bonobos has done a good job with with TechStyle. See video below:



Samsung has a glove called Samsung Fingers here. The best thing I liked was 'Talk to the Hand'

Samsung Fingers_Talk to the hand

HTC came up with similar concept called Gluuv



Toshiba's DiGiT is as interesting. See the video:


Virgin Mobile, Canada has come up with SmartKicks. See here.



Roku Watch is not too bad:


Virgin America even convinced Sir Richard Branson to appear in the April Fools ad along with Tony Faddell, the CEO of Nest. Funny Youtube video here.

Sony Power Food was just okay, video here.

Toshiba Spehere is a funny Gaming concept, see here.

Nokia reviewed its most popular phone 3310 with modern day features here. Coloured screen with 41Megapixel camera.

Google wants to Emojify the web here.

Google Japan has a magic hand here.

Selfiebot by Orbotix is a cool concept, here.

Twitter Helmet didnt make me laugh though. See here.

Is there some others that I missed? Please feel free to add it in the comments.

A quick case study on Smartwatches

My presentation from the Cambridge Wireless Connected devices SIG event "On Trend – High Fashion meets High Technology" held today, is embedded below. One of my favourite ads that highlights our fascination with the smart watches has been shown very well in a advert by Samsung mobile USA as follows:


I believe there is an opportunity and a market for the smart wear and smartwatches. There is a need for just the right kind of products to capitalise on the demand.

5G and the ‘Millimeter-Wave' Radios


There were quite a few interesting talks in the Cambridge Wireless Radio Technology SIG event last week. The ones that caught my attention and I want to highlight here are as follows.

The mobile operator EE and 5GIC centre explained the challenges faced during the Practical deployments. Of particular interest was the considerations during deployments. The outdoor environments can change in no time with things like foliage, signage or even during certain festivals. This can impact the radio path and may knock out certain small cells or backhaul. The presentation is available to view and download here.


Another interesting presentation was from Bluwireless on the 60GHz for backhaul. The slide that was really shocking was the impact of regulation in the US and the EU. This regulation difference means that a backhaul link could be expensive and impractical in certain scenarios in the EU while similar deployments in the US would be considerably cheaper. This presentation is available here.


Finally, the presentation from Samsung highlighted their vision and showed the test results of their mmWave prototype. The presentation is embedded below and is available here.



Finally, our 5G presentation summarising our opinion and what 5G may contain is available here. Dont forget to see the interesting discussion in the comments area.

Dumbphones, Featurephones, Smartphones, Superphones...

Looks like there is still a lot of confusion in the different types of phones around so here is my take. Please feel free to correct me and I will update accordingly.

Dumb phones: The dumb phones were the original mobile phones whose intention was to allow voice and SMS initially and then later on some kind of data transfer using WAP.

Pic source: iPhaze

A typical dumbphone is as shown above. Dumb phones are no longer available but they can still be used if they are in the working order. Dumbphones were always pre-3G. It wouldnt make sense to have a 3G dumbphone but it is very much possible to have a 2G Featurephone/Smartphone.

Feature Phones: These came next. They allowed more stuff than the basic phones.

Pic source: Gadgetsteria

Featurephones (above) can do much more stuff, for example they may have camera to take photos, they may allow facebook to share the photos, they can have Skype to call, they can even have WiFi for access. Different people have different way of describing the difference between them and smartphones. Some distinguish Featurephones by suggesting that they have a closed operating system (OS) but this may not be necessarily true. Some others suggest that featurephones do not have touch screens while smartphones do, again this may no longer be considered true. There are featurephones available with basic touch functionality. I think an agreeable way to consider a phone a feature phone, in today's terms, can be based on a combination of processor speeds (less than 400MHz), screen size (less than 2inches), presence of physical buttons and pricepoint (less than $50).

Contrary to popular belief, featurephones are still popular and are going strong. See the chart below for example.
Pic source: Seeking Alpha

There is a good article that explains why Feature phone is 'Still the undisputed King' here to interested readers. The main reason according to me is that the reception is much better on Featurephones rather than Smartphones and they consume less battery power in general as compared to the smartphones.

Smartphones: Wikipedia suggests that the term smartphone was used as early as 1997 but what may have been considered as smartphone then is more like a featurephone of today. As per my knowledge, the first true modern smartphone were the Nokia communicators. If you look at the specs now, they may be classified as low end featurephones but they were the foundation for the smartphones.

Picture Source: Droid techy news

The first true modern smartphone that change the mobiles forever is undisputedly the original iPhone. On reflecting back, people had no idea what a phone could do until the arrival of the iPhone. This was soon followed by the iPhone clones and now we have many different ecosystems like Android, Bada, Windows mobile, Blackberry OS, etc. that gives its own flavour to the smartphones.

Superphones: The marketing industry is always thinking of using new terms to sell the products and while there has been terms like smarter-phones, super-smartphones, intelligent phones, etc. being thrown about, I think the industry has now converged on to use Superphones for the next generation devices. Some of the readers may be aware that 'Superphone' is used in Dr. Who series.


Again, there is no defined standards but looks like the superphone should have Quad core and its screen size should be more than 4.1inch. Samsung Galaxy S3 would qualify to be a superphone but its not referred to as one.

Phablets, Tabphones and Phonetabs: So what do you call a hybrid (or a cross between) Tablet and Smartphone? The answer could be any of the terms Phablets, Tabphones or Phonetabs. Again, there is no standard term but people have decided to use whichever term they feel like. Phablet is the most commonly used term.

Pic Source: CNet

Samsung Galaxy Note 2 is a good example of Phablet. One of the suggestions is that to qualify for Phablet, the screen size should be between 5 inches and 7 inches. Some of the users who have braved to buy one of the phablets, swear by it and in most cases vow to never go back to just a phone.

Picture Source: FT

FT has an interesting article that suggests the shipment of phablets could be around 200 million by 2015. It should be noted that according to me, WiFi only devices should not be considered as phablets as the phone part is missing. They are just mini-tablets. In case of 7 inch devices capable of phone and tablet functionality, it is a bit of a fuzzy area in cases where the user does not use the SIM card, thereby making the phone part unusable. For simplicity we can consider a device as phablet as long as the mobile functionality is embedded.

UK: Spectrum, Operators, Vendors and LTE

So LTE (or '4G') is about to be launched in the UK as announced yesterday. Its going to be branded as 4GEE.

Here is a summary of the Spectrum in the UK that will be used for LTE and would be auctioned by Ofcom.


Here is the current allocation of Spectrum in the UK

The above pics are from a presentation by Ofcom in LTE World Summit 2012 in Barcelona, available here.



The last table is from an Ofcom document here. Its very interesting read. For example I didnt know that The L-band was the first major part of Ofcom spectrum awards programme relevant to mobile services. It consists of 40MHz between 1452MHz and 1492MHz. The auction took place in May 2008, in which Qualcomm won the entirety of the available spectrum.

Here is the summary of the operators working on LTE:


Everything Everywhere (EE = Orange + T-Mobile) - They are calling their '4G' service as EE, covering up to 70% of the UK by the end of 2013. Network kit provided by Huawei.

Three - Samsung will provide the Radio Access Network, and the core infrastructure, for Three's LTE (4G) network. That includes the base stations, and radio core. 3 UK has agreed to purchase 2 x 15 MHz of 1800 MHz spectrum from Everything everywhere, and plans commercial launch of LTE service in 2013.

Telefonica (O2) trial network - Equipment supplied by Nokia Siemens Networks (NSN) for both the Radio and Core network elements. Backhaul for the 4G trial network has been provided using Microwave Radio Equipment from Cambridge Broadband Networks Limited, NEC and Nokia Siemens Networks.

Updated 13/09/12 - 11:25

UK Broadband rolled out the first commercial TD-LTE network in London back in February (available to customers since May 2012). The equipment is provided by Huawei. They have 40MHz in Band 42 (3.5GHz) and 84MHz in band 43 (3.6GHz).

Vodafone - No news.


Anything else I missed?

A Twitter discussion on eMBMS




@zahidtg: Samsung has demoed eMBMS using Anritsu RTD system - http://bit.ly/PCGb99  - But is any operator interested?

Korean consumer electronics giant Samsung has successfully demonstrated the clear delivery of television broadcast signals over an LTE 4G wireless network.
 
Samsung is using evolved Multimedia Broadcast Multicast Service (eMBMS) technology and has tapped test & measurement specialist Anritsu's Rapid Test Designer (RTD) and MD8430A to simulate the LTE network environment used for the demonstration. 
eMBMS technology allows carriers to adjust coverage and capacity as needed, allowing for more efficient use of network resources in order to better handle the heavy traffic load that broadcast video would present. 
Samsung is actively looking to add more content to the value proposition for its phones. It has deployed its own Hub strategy for its Galaxy line of smartphones, which includes a Music Hub, Movies Hub and Games Hub, all of which give the handset-maker a new incremental revenue stream. A TV Hub that could support live TV content in addition to on-demand episode downloads could add a compelling new wrinkle in that pseudo-walled garden approach. 
Samsung is also instrumental in bringing mobile TV to market via the Dyle initiative for mobile DTV—a service that offers live broadcast feeds from local TV affiliates over separate, dedicated broadcast spectrum. No. 5 U.S. wireless carrier MetroPCS just went live with Dyle service and a Samsung mobile DTV-compatible smartphone.

@KimKLarsen: Depends on whether an operator believes in the broadcast over mobile model. Mobile User trends seems not in favor at least in WEU.

@zahidtg: I agree and thats why I dont think broadcast will work in the short term. Would be different is Apple were to create biz model:)

@KimKLarsen: though the question is whether they (Apple/Google) really need eMBMS for executing such a business model ... I guess not really?!

@KimKLarsen: I have a couple of beautiful white papers on satellite (w & wo terrestrial component) eMBMS using S-band together w Apple or Google

@zahidtg: True. My point is that they are the ones who can create a new biz model on it, operators cant be bothered. Too much hassle.

@KimKLarsen: too much hassle, too little new revenue, risky ROI, insufficient scale, etc.. an Apple or alike might overcome due to shear scale!

@KimKLarsen: though w a satellite (w. city based terrestrial component) based eMBMS system you cover large landmass & pop & get the Scale!

@Qualcomm_Tech: I think the best initial use case for #eMBMS is to selectivley use it as venue casting at stadiums/exhibitons etc.

@kitkilgour: "ClipCasting" has been the main eMBMS use case - stadia, or catching up on your 1min news at stations

@Qualcomm_Tech: True, Any content destined to venue users, incl. live/real-time can leverage eMBMS- huge capacity increase

@KimKLarsen: I agree! Might be interesting! But can this really justify eMBMS as a service for mass adaption?

@KimKLarsen: when will eMBMS be supported in Gobi? & when can we expect this to be standard in all LTE terminal devices?

@kitkilgour: It's networks as well as devices. MBMS has always been hampered by needing to reach the cell edge ...

@kitkilgour: ... with limited / no power control whilst minimising interference to others

@KimKLarsen: great feedback! Thanks! Do you see a need for denser networks to deliver a uniform MBMS service than for standard data services?

@KimKLarsen: one of the challenges we have had in nominal terrestrial MBMS designs have been link budget requirements! Any good sources?

@Qualcomm_Tech: challenge’s been having enough penetration of multicast devices. Venue cast solves that problem #1000x

@KimKLarsen: Sounds like Venue Cast is The Main Driver for eMBMS adoptation? (hmmm?) What's the Revenue Source? #42x

@KimKLarsen: I don't understand how Venue Cast can Drive MC Device Uptake? The other way around more reasonable! #42x

@Qualcomm_Tech: Target specific groups, eg season ticket holders & offer attractive device/content/plan bundles #1000x

In other news, Huawei Launches eMBMS Innovation Center to Develop LTE Solutions:


Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the launch of an enhanced Multimedia Broadcast Multicast Service (eMBMS) innovation center in Shenzhen in order to develop end-to-end eMBMS solutions and LTE applications. 
eMBMS is a 3GPP R9 standard for mobile video that enables a higher transfer capacity over typical MBMS technologies. Huawei's eMBMS innovation center will focus on on-demand video services and broadcast information based on eMBMS. This will enrich LTE applications and accelerate the development of the eMBMS industry chain, which includes chipsets, devices, and network equipment.
In addition to developing solutions, the innovation center will also serve as an experience center for operators. Video, mobile TV, and advertisements will be showcased via mobile smart devices employing Huawei's eMBMS solution. Global operators from Europe, Asia, the South Pacific and other regions have already visited the center to experience its LTE demonstrations.
Huawei has been committed to the growing mobile video market since 2006. According to the Global mobile Supplier Association's (GSA) “Mobile Broadband Status Report”, over four billion people watch videos on YouTube every day. This large-scale usage is leading to increased revenue. According to a report from Global Industry Analysts, revenue from the mobile video market will reach USD30 billion by 2017. Huawei's eMBMS research team works closely with operators, chipset and device manufactures and other partners to further the development of the industry for the benefit of all end users.
Huawei's LTE division has been committed to providing the best commercially performing network, the best end user experience through devices and innovative services, as well as end-to-end convergent solutions for helping operators with their business success. Huawei's eMBMS innovation center will push the development of mobile video well into the future.

Phones with Flexible Screens in 2012


From PC World:


Samsung Electronics said Friday that it is aiming to launch mobile phones with flexible displays next year, with tablets and other portable devices to have these displays soon after.
The company said it was aiming to follow on the success of its Galaxy S II smartphone, which has now sold 10 million units in five months.
The comments came as the company discussed its earnings for the three-month period through September. Samsung said its overall profit fell 23 percent from a year ago to 3.44 trillion Korean won (US$3.1 billion), dragged down by its chip and display operations, but operating profit at its mobile unit more than doubled in the period.
"The flexible display, we are looking to introduce sometime in 2012, hopefully the earlier part," said spokesman Robert Yi during an earnings call. "The application probably will start from the handset side."
Yi said tablets and other mobile devices with flexible displays would follow.
Samsung has shown flexible OLED (organic light emitting diode) displays inside rigid cases that kept the screens curved. The technology has material within each pixel that generates light, making it perhaps more suitable for flexible screens than LCDs, which would require both a flexible screen and a backlight.

This is a Video from CES 2011 in January:



I like this concept of bendy phones. The following Nokia video shows how this could really be useful.



Toshiba shows something similar at SID 2010.

IMB and TDtv (and DVB-H)

Its long time since I blogged about TDtv. Its been quite a while since I heard about TDtv. Apparently its been superseded by IMB, aka. Integrated Mobile Broadcast.



IMB is used to stream live video and store popular content on the device for later consumption. This results in a significant offloading of data intensive traffic from existing 3G unicast networks and an improved customer experience. The multimedia client features an intuitive electronic program guide, channel grid and embedded video player for live TV viewing and video recording. All IMB applications can be quickly and cost-effectively adapted to support all major mobile operating systems and different mobile device types, including smartphones, tablets and e-readers.

IMB was defined in the 3GPP release 8 standards, and was recently endorsed by the GSMA as their preferred method for the efficient delivery of broadcast services. In June 2010, O2, Orange and Vodafone – three of the five major UK mobile operators – announced that they have teamed up for a three-month trial that will explore IMB wireless technology within a tranche of 3G TDD spectrum.

This spectrum already forms part of the 3G licenses held by many European mobile operators, but has remained largely unused because of a lack of appropriate technology. Currently, 3G TDD spectrum is available to over 150 operators across 60 countries, covering more than half a billion subscribers. IMB enables spectrally efficient delivery of broadcast services in the TDD spectrum based on techniques that are aligned with existing FDD WCDMA standards. This enables a smooth handover between IMB and existing 3G networks.

Issues that previously limited uptake of IMB, or IPWireless' tdTV system, have now all been addressed. Namely, the standard now allows for smooth handover between IMB and unicast delivery; has the potential to be integrated onto a single W-CDMA chip rather than requiring a separate chip; and has resolved interference issues with FDD W-CDMA, at least for spectrum in the 1900MHz to 1910MHz range.

IP Wireless already had a trial at Orange and T-Mobile in the UK (which have just agreed to merge), but in that pilot each 5MHz segment only gave rise to 14 TV channels per operator. The new standard could support 40 separate TV channels if two operators shared their TDD spectrum.

The GSMA announced its support and is backed up with additional support from both IPWireless and Ericsson as well as operators Orange, Softbank and Telstra.

There have been recently quite a few bad news for DVB-H and on top of that IP Wireless has announced that Samsung is going to be releasing phones with IMB support so it may be that we will see IMB sometime next year.

The GSMA paper that details IMB service scenarios and System requirements is embedded below:

Nokia Siemens Networks demonstrate TD-LTE leadership

Since last few months, NSN have been showing that they are serious about TD-LTE as well. Back in June they made an announcement that they have integrated TD-LTE in their networks so that it can support concurrent use of TD-SCDMA and TD-LTE. They opened a TD-LTE lab in China as well earlier this year.

Motorola is another big player in the TD-LTE arena and I have blogged about them as well. With the purchase of Motorola Networks by NSN, it got additional experience and capability to be the next TD-LTE leader. With this renewed confidence, it ended the joint venture with Huawei which started back in 2005 with TD-SCDMA technology.

The following is press release from NSN couple of days back:

Nokia Siemens Networks has proven its leading role in advancing TD-LTE as it met the complete TD-LTE test specifications defined by China’s Ministry of Industry and Information Technology (MIIT). The successful completion of the trial in the 2.3GHz band at the MIIT lab in Beijing, China, marks an important milestone in the commercialization of TD-LTE. After the test, Nokia Siemens Networks also achieved the world’s first high-definition TD-LTE video call, including handover, with a Samsung TD-LTE device.

The high-definition video call demo showcased interoperability between Nokia Siemens Networks’ LTE infrastructure and Samsung’s TD-LTE USB dongle, and marks a definitive step toward ensuring early availability of a functioning TD-LTE ecosystem for commercial deployments.

“We’ve achieved excellent results from this test and are happy to partner with Nokia Siemens Networks in driving the TD-LTE ecosystem further,” said Mr. Tong Wang, president of Beijing Samsung Telecom R&D Center. “Commercial readiness of devices is a key indicator for the success of a new technology and the current test results show that we are now well prepared for TD-LTE.”

“Meeting TD-LTE test specifications defined by MIIT and achieving the first high-definition video call with handover, are key milestones in our list of achievements, added Paul Pan, head of Network Systems, Greater China Region, Nokia Siemens Networks. “We will continue to collaborate with partners to accelerate our progress toward a comprehensive deployment of TD-LTE.”

Nokia Siemens Networks is at the forefront of TD-LTE development and commercialization, actively working with telecom operators and device manufacturers. The company recently announced the first TD-LTE interoperability data call with a prototype TD-LTE USB dongle from Samsung and the first TD-LTE video call between Shanghai and Taipei.


Ericsson is now going to probably have tough competition from NSN.

Samsung v/s Apple Display War



In launching the new iPhone at the Worldwide Developers Conference in San Francisco last week, the Apple front man claimed the screen's IPS LCD technology, developed by LG and Hitachi, also offered superior colour resolution and was “quite a bit better” than Super AMOLED overall.

“You can‘t make an OLED display with this type of resolution right now,” Jobs said on stage. “Retina Display is going to set the standard for displays for the next several years. We don’t think anybody’s going to come close.”

But Samsung disagrees, claiming that the difference in the total number of pixels over Super AMOLED's 800 x 480-pixel resolution is all but negligible to the naked eye, and pointed instead to Super AMOLED's emissive lighting and its ability to deliver far better colour and contrast than more traditional backlit screens like the Retina Display.

"The visibility difference is only 3 to 5 per cent. But raising resolution to that level increases battery consumption by 30 percent,” a Samsung spokesperson told the Korean Herald. “Structurally, IPS LCD technology cannot catch up with AMOLED display technology,” .

One of Super AMOLED's chief attractions is the reduced strain on the battery thanks to that lack of backlighting, with Samsung's new Wave smartphone offering double the battery life of the iPhone. In addition, the Samsung screen offers a contrast ratio thought to be around 1,000,000:1, dwarfing the iPhone's figure of just 800:1.

According to Jobs, the iPhone's screen's 326 pixels per inch meant it had a higher resolution than the human eye “The display is your window into the internet, into your apps, into your media, into your software,” he said. “Retina Display is the best window on the planet.”

Its good to see the Mobile Display evolving but not sure if everyone cares about it. There is a good comparison of AMOLED v/s LCD with lots of pictures here, which will give you a good idea. More details here as well.

BBC and Ubiquisys stream multiple videos over a femtocell at MWC 2010



Impressive. I suppose they are four simultaneous PS dedicated calls as all other approaches (Like Mobile TV Broadcast technology and MBMS) would not be applicable for Femtocells (atleast for now).

Bluetooth 3.0 to see the light of day soon

Picture Source: 3g.co.uk and simbasics.co.uk

Remember Bluetooth 3.0? Its been a while and the world has changed in the mean time.

Samsung S8500 will launch next-generation Bluetooth 3.0, a protocol that will establish transfer speeds up to eight times faster than 2.0… 24mbps!

Samsung have not been officially announced yet to carry the Bluetooth 3.0 on the S8500 but the device has been leaked to carry 3.0 Bluetooth connectivity that will dwarf previous 3mbps speeds.

The listing from the Bluetooth Special Interest Group it is slim, compact, will come in several colours, and also contains quad-band GSM/EDGE radios. Other details are scarce, and it’s likely that the spec may change considerably before we get our hands on the actual handset

Broadcom is also focusing on Bluetooth 3.0, which allows Bluetooth-centric designers to use the 802.11 physical layer to provide Wi-Fi-speed data transfers in a Bluetooth environment. Bluetooth 3.0 supports bulk synchronization of music libraries between PCs and music players or phones, supports wireless transfer of photos to printers, and sends video files from cameras or phones to computers or televisions. An alternative for Wi-Fi-centric designers, says Ochikubo, is Wi-Fi Direct, which enables Wi-Fi devices to connect and share data without joining a traditional home, office, or hot-spot network. Whatever approach Broadcom’s customers choose to take, he says, he sees Broadcom’s recently announced InConcert Maestro software platform as making the operation simple and transparent for the end user.

In addition to focusing on the higher speeds that Bluetooth 3.0’s Wi-Fi physical layer affords, the Bluetooth Special Interest Group is also focusing on low-power applications with its “Bluetooth low-energy,” or Bluetooth 4.0, specification. Bluetooth low energy will address markets such as health care, sports and fitness, security, and home entertainment.
