Smarter Cars of the Future

We all know that cars are getting smarter. Back in Oct., Google unveiled the cars that can drive by themselves. I am sure they will make our life much better and we will be able to catch on the sleep at early morning commute.

Then there were quite a few futuristic cars at the CES 2011 last month. One such video is embedded below.

The following is a summary from the an IEEE article:

Cars have been getting smarter for years, studded with suites of sensors and supporting electronics aimed at keeping them from crashing. But entertainment and convenience have rapidly caught up to safety as the impetus for new in-car electronics development. Because automakers typically spend three years developing and producing new cars—and new gadget candy to go with them—they’ve found themselves constantly playing catch-up with consumer electronics and consumer expectations. So car companies have teamed up with the makers of smartphone software platforms to integrate a spectacular array of apps designed for handsets with cars’ digital dashboards, center consoles, and speaker systems.

Take for instance Ford’s new Focus all-electric vehicle, which made a big splash at the 2011 International Consumer Electronics Show in Las Vegas last month. It features a software application called MyFord Mobile.

The app, which runs on Ford’s proprietary Sync platform and is compatible with the BlackBerry, iPhone, and Android devices, links the car with the driver’s smartphone and home computer. The software lets the driver listen to a smartphone’s music library and lets passengers watch movies or TV shows. It delivers information such as when electricity prices are at their lowest (to allow for the cheapest battery recharging) and where the nearest charging stations are. And it allows a smartphone to function as a remote control, by means of a connection to cloud-based servers. This remote communication lets the handset keep tabs on the car’s location and the batteries’ state of charge. It will also let the driver start the Focus EV from indoors on a blustery January morning, then step into a car whose seats and steering wheel are already warm. The MyFord Mobile app lets the driver remotely start the car, turn on the heater or air conditioner, or unlock the doors from anywhere in the world (including beneath the bedcovers).

And because the system differentiates one driver’s key from another’s, it presents information on the reconfigurable 4-inch screens on either side of the speedometer in the current driver’s preferred color and style. The state of charge, for example, could be shown as a percentage of the full charge, as an estimate of the remaining miles before recharging, or as a simple bar that gets shorter as the batteries’ energy is consumed. This differentiation also works for utility and entertainment options; it automatically queues up driver A’s list of radio station presets, favorite mobile apps, and preferred display options for the 8-inch center console touch screen. Because MyFord Mobile links the Focus to the driver’s handset, it can also access his or her contact list for hands-free calling and read out e-mails and texts through the car’s speakers.

Ford is trying to position itself as a technological leader in the automotive industry with MyFord Mobile and Sync AppLink Voice Control, which puts the driver in control of all the Sync system’s capabilities via voice commands, but it has stiff competition from the likes of Mercedes-Benz, Continental, and Toyota. Launched by Mercedes-Benz in November 2009, the Mbrace system, designed and engineered by Hughes Telematics of Atlanta, was the first telematics service on the market to give smartphones the power to remotely lock, unlock, or locate a car. It didn’t signal a revolution in the way the average driver interacts with his or her vehicle because when the German luxury vehicle maker offers a new technology or set of features, there is usually a multiyear wait for them to trickle down to cars whose sticker prices aren’t stratospheric.

The second generation of Mbrace debuted last September. It introduced Mercedes-Benz Concierge, which not only opens the car to information from the outside but also makes some car-based information and entertainment options portable. The Mbrace Mobile Application 2.0 gives iPhone and Blackberry users single-phone-number access to recommendations for nearby entertainment and restaurant options, directions, traffic updates, and more, whether the person is in the car or not. The concierge then sends destination information to the smartphone or directly to the in-vehicle navigation system. With the Mbrace system’s latest wrinkle, the Drive2Friend service, the driver can dictate a friend’s mobile number and the app sends a text message reporting that the driver is trying to find the person. The friend has the option of allowing his or her location to be sent back to the car via cellular triangulation.

While Ford was showing off its wares at CES, Continental was also there showcasing the Android-based AutoLinQ system, which lets the driver connect to the car in three ways.

AutoLinQ’s Mobile View lets you to send text messages to your car; the smart vehicle can text you back with information such as its location. In this demo [Flash video], a smartphone user is shown making a remote inquiry about the status of his car. Mobile View reports that the sunroof is open and offers the option to close it or ignore the warning. When he taps Close on the handset’s touch screen, the sunroof’s glass panel glides shut. This type of call-and-response vehicle update also tells whether doors are closed and locked and whether the headlights or interior lights are on. Mobile View doesn’t wait for a query to alert the driver when the alarm is triggered, the battery is depleted, the air bag has been activated, or the internal temperature of the car is too high or low. And like MyFord Mobile, it turns the smartphone into a remote control for locking and unlocking the doors, starting the engine, flashing the lights, and more.

AutoLinQ’s Home View lets you download apps and configure vehicle settings from your home computer. Clickable tabs at the bottom of the Home View screen let the car owner move through screens showing a wealth of data on the car’s status, driver preferences, navigation information, and applications that can be downloaded or fine-tuned. The status menu tells whether the ignition is on and displays the fuel and motor oil levels, the pressure for each of the four tires, and much, much more.

Car View, in AutoLinQ, is for updating features from the driver’s seat. Car View provides the same information as Home View but lets the driver use the center console touch screen to download apps on the fly that provide better control of the car and the ability to remotely manipulate electronic devices back home. An app that sends an alert when a game or match in the driver’s favorite sport is about to appear on television also gives the option to activate a digital video recorder at home, pull up a Web site featuring periodic updates about the game, or listen to play-by-play on the radio.

Continental is also designing unique apps that will enhance vehicle performance. For instance, the Filling Assistant will detect underinflated tires and notify the driver. When the driver goes to inflate the tires, the Filling Assistant will report pressure information to the driver’s smartphone and honk the car’s horn or flash its lights to indicate when a tire has enough air.

Not to be left out, Toyota, the world’s leading automaker, debuted the QNX-based Entune at CES 2011. Entune is an upgradable suite of entertainment, navigation, and information functions. "Consumers have grown accustomed to having the world at their fingertips through their mobile phones," says Jon Bucci, vice president of Toyota’s advanced technology department, who notes that putting them in the car is a natural evolution.

After downloading the Toyota Entune app to a handset and syncing it with the Toyota vehicle, the driver can begin accessing content and services, including Bing for Web navigation and OpenTable, which can make reservations at any one of 15 000 restaurants, with directions sent seamlessly to the navigation system and information appearing on the center console. Entune also lets a driver get customizable real-time traffic updates, sports, weather, stocks, and information on prices at local fueling stations. The system doesn’t forget music, which has almost always been a part of the driving experience. Entune includes Iheartradio, which delivers roughly 750 local radio stations at the touch of a button.

The tide of apps extending handset capabilities to cars will only continue to rise. ABI Research, in Oyster Bay, N.Y., reports that the number of users of automotive apps will increase from 1.4 million in 2010 to more than 28 million by 2015. And according to Global Industry Analysts, the vehicle telematics market is expected to reach US $11.2 billion by 2015.

'EU-Alert' in Release-11

In the recently concluded 3GPP CT-50 in Istanbul, EU-Alert was adopted as part of Rel-11. The EU-Alert is introduced under Public Warning System (PWS) in parallel with Earthquake and Tsunami Warning System (ETWS).

PWS was introduced in Rel-9 and I blogged about it here. ETWS has been around since Rel-8 and was blogged here.

In fact EU-Alert is sent as part of the Cell Broadcast Message (CBS) using new identifiers. For more details see 3GPP TS 23.401.

The following is an old video from CHORIST project, which was instrumental in providing details of working of this EU-Alert system.

Making small purchases simpler with Ericsson IPX

Yesterday a colleague made me aware of this Ericsson's IPX SMS based payment system that looks like a competitor to the NFC technology and doesn't involve any additional chip/hardware. Here is a video:

From Ericsson's website:

Ericsson Internet Payment Exchange (IPX) is a leading mobile aggregator, providing delivery and billing services, via SMS, MMS, web and online mobile billing, to more than 2 billion mobile subscribers across 26 countries. Ericsson IPX also brokers location information in selected countries and Ericsson IPX Messaging provides reach to 96% of all mobile subscribers worldwide with SMS. Ericsson IPX customers are companies who offer digital content, mobile voting & directory information and enterprises offering mobile marketing, communities and banking.

Now, we all love SMS and we have to admit that its the simplest of technology and even the most primitive phone nowadays support it but there could be scenarios when this can be a bit of a problem:

1. SMS can sometimes be delayed if a particular cell is overloaded, etc. So how long do we have to stand in front of the machine?

2. If say for 2-3 mins we do not receive an indication that the machine has a cash, do we send another SMS to cancel the transaction?

3. If we have a problem, do we have a support number to call to? How much will that cost?

4. If there is a queue of people and someone else wants to purchase something as well, does the next person has to wait till the person before has received the item?

5. If two people have sent an SMS, how do they know whose cash is in the machine now? Do we start putting a Pin as well ?

I agree, this technology could be really useful if you have run out of cash (even if you have NFC chip) and you need to purchase something small.

The other obvious advantage is that you can target advertisement at regular users who are at a particular place at a particular time to make them buy something. Also you can get statistics like what time people tend to purchase, what do they purchase, where, etc.

Anyway, hard for me to see this take off big time.

Wilson Street: What can femtocells do - the next big thing!

I have blogged about the Alcatel-Lucent (ALU) Femtocells in the past. Few months back I posted about their shift from using the term Femtocells to Small cells. To make everyone aware of this small cells they launched their Wilson Street experiment and are now producing some episodes to show how these small cells can play big part in everyday life.

The first two episodes are embedded below from Youtube.

Mozilla Seabird – A Community-driven Mobile Phone Concept

Since Mozilla Labs launched the Concept Series with an open call for participation we’ve had thousands of people join in, share ideas and develop concepts around Firefox, the Mozilla projects and the Open Web as a whole.

In response to our open call Billy May, in early 2009, produced a throw-away concept for an “Open Web Concept Phone”. Working directly off of that community feedback, Billy has since finished the exploration with his concept “Seabird”.

The following write-up is by Billy May and explores what an Open Web phone might look like:



The Mozilla Seabird, part of the Mozilla Labs’ Concept Series, is an experiment in how users might interact with their mobile content as devices and technology advances. Drawing on insights culled from the Mozilla community through the project’s blog, a focus quickly developed around frustrating physical interactions. While mobile CPUs, connectivity and development platforms begin approaching that of desktops, the lagging ability to efficiently input information has grown ever more pronounced.

Wireless Power Consortium (WPC) launches Qi

The WPC has chosen the Qi logo as the international symbol of wireless charging compatibility. Qi—pronounced “chee”, meaning “vital energy” in Asian philosophy—represents an intangible flow of power. Qi is the sign of interoperability between power transmitters and power receivers. All Qi receivers will work with any Qi transmitter. Every electronic device bearing the Qi symbol can be charged on any charging pad or surface marked with the same Qi logo.

In a post last year I mentioned about the wireless chargers. There were few that were released but they are expensive and not sure about the reliability.

The following is from eWeek:

The Wireless Power Consortium (WPC) has launched version 1.0 of its specification for charging handsets and other devices wirelessly, to be marketed under the name “Qi”, and has certified initial products for Blackberry and iPhone devices.

The product announcements come a year after the consortium announced version .95 of the spec. The products, including chargers for iPhone and BlackBerry devices, are to be demonstrated at a WPC meeting later this month.

Qi is based on inductive power transmission, already used in products such as the Touchstone charging dock used by the Palm Pre and the charging station for the Wii gaming console remote control. Such chargers allow a device to charge when placed on a flat surface or in a sleeve or dock. They eliminate the need for the connection of a metal contact connection, such as is found in standard cordless phone chargers.

The consortium, which includes Samsung, Sanyo, Olympus, Philips and Texas Instruments, aims to standardise inductive power charging technology so that chargers can be used with any device bearing the Qi logo. The specification is suitable for devices using up to 5 Watts of power, which the WPC said should cover “the majority of handheld mobile devices”.

“Qi can now be integrated into products. All ingredients for growing the market are now on the table,” said WPC chair Menno Treffers, in a statement.

Initial Qi-certified products are to include a charging sleeve for the iPhone 3GS and 3G and a charger for the Blackberry Curve 8900, both to be launched by Energizer this autumn. Sanyo, ST-Ericsson, National Semiconductor and others said they are working on Qi products.

Prototypes are to be demonstrated at a WPC meeting in Eindhoven, Belgium, from 15 to 16 September. The WPC said it has now begun work on a wireless charging specification for devices requiring more power, including netbooks, laptops, tablet computers and power tools.

The consortium said it chose the brand Qi (pronounced “chee”) to refer to the concept of energy flow in traditional Chinese medicine, not the cult quiz show QI (for “quite interesting”) hosted by Stephen Fry on British TV.

The technology is less ambitious than the system demonstrated this summer by Witricity, which operates at a distance of a few metres, using resonance, which the company claims has green benefits through replacing disposable batteries

From ZDNet:

"It took us only 18 months to develop the Qi standard, and less than one month to see the first products certified. Qi is now the industry's choice for wireless power," said Menno Treffers, chairman of the WPC, in a statement.

Three sets of specifications — for interface definition, performance requirements and test procedure — were handed over to consortium members in July. The only standard released publicly as Qi 1.0 is the interface definition, with the others being restricted to consortium members. The WPC has grown from 27 members in July to over 55 members, including Nokia, LG, Research In Motion, Duracell, Energiser and Texas Instruments.

Wireless charging has great potential to make charging easier for consumers", said Petri Vuori, Nokia's director of mobile solutions research, in the WPC announcement statement. "For full user benefit, a standard ensuring cross-compatibility between different manufacturers' products is required. Qi low-power standard specification release 1.0 is a significant milestone into this direction."

The Qi standard uses inductive charging to transfer up to 5W of power between devices and chargers. There are already products on the market that support inductive charging, but these are tied to particular products, rather than being universal.

The WPC said that it now plans to begin work on a wireless power standard for medium power devices such as netbooks, laptops, tablet computers and power tools.

The group expects the technology to boost the market for wireless battery charging from 100,000 units to 100,000,000 units annually. "Qi can now be integrated into products. All ingredients for growing the market are now on the table." said Treffers.

Everyone is talking NFC

Its been over couple of years since I blogged about what NFC is. In fact successful trials in London occurred around that time but it seems the operators always had doubts.

Couple of months back, Nokia announced that from 2011, it will roll out NFC in all it phones. Here is an extract from the Register:

Nokia has announced that from next year every Nokia smartphone will have NFC, regardless of fact that the technology lacks a business model or any market demand.

The commitment was made during a speech by Nokia's VP for markets, Anssi Vanjoki to the Moby Forum, as reported by NFC World. Vanjoki wouldn't be drawn on the company's smartphone plans, but did explain that every smartphone launched by Nokia would have an NFC component supporting the Single Wire Protocol (SWP) and MicroSD security, and probably a Nokia secure module too.

Once NFC is in a handset then one can do some interesting things with remote control of home electronics and Bluetooth pairing-by-tap, but none of that is the killer feature that NFC needs to make it viable.


Of course, the mobile industry isn't used to waiting for customer demand – no one ever requested a camera, or Bluetooth, those were pushed into punters' hands by operators (to sell MMS) and retailers (to sell headsets) respectively. But those were done by the network operators (which explains the popularity of Bluetooth in Europe, where operators own retailers).
Nokia, which has extensive IP in NFC, has spent a fortune trying to convince operators to back the technology, funding extensive trials and backing supportive research, but no matter how hard it tries, NFC just isn't desirable (at least until Apple puts it into an iPhone).

That was till last week. This week the news is out that Apple is testing NFC in iPhones. The following news from CNET:

Apple raised some eyebrows over the weekend when news spread it had hired an expert in mobile payments.

But now there's a report that says the company is already testing a prototype iPhone with near-field communication (NFC) chips inside, which could pave the way for using future iPhones as a mobile wallet.

TechCrunch heard from an unnamed source that on Tuesday Apple is testing an iPhone with NFC chips it's ordered from NXP Semiconductor. It's not clear what kind of tests, and it could be very preliminary in nature. But coupled with the hire of Benjamin Vigier from mFoundry as mobile payments product manager, it does seem possible that Apple could be planning to open up its premier product to the world of commerce outside of iTunes.

In fact you may be able to do much more than mobile payments if Apple gets its way. You may be able to sync devices by touching each other. You can sync your MAC to iPhone or iPod. Here is a video showing some iPhone RFID demo, courtesy NFC world.

Coordinated Multi-Point (CoMP): Unresolved problems

I have blogged about CoMP in quite some detail in the past. Someone recently pointed out an interesting video from Fraunhofer Heinrich Hertz Institut which is embedded below:

CoMP may be not as practical as we may think. One of the things pointed out by Dr. Ariela Zeira, InterDigital's Vice-President of Advanced Air Interfaces in the LTE World Summit was that there exists a gap between the theoretical and the practical gains of CoMP.

She went on to suggest the following as way forward for the Coordinated Multipoint acceptance in future:

• Address root causes of gaps between academia and current feedback schemes
• Need for improved Channel State Information (CSI) feedback resolution
• Need for improved frequency domain precoding granularity
• Apply CoMP where most needed and/or theoretical gains can be approached
• Heterogeneous networks
• Interference problem is more severe than in macro-only deployment
• Especially for Femto Closed Subscriber Group and Pico Cells employing large cell extension
• Lower delay spread and low mobility can be expected in Femto and Pico cells and reduce performance loss from feedback impairments
• Relay Backhaul Channel (RBC)
• More accurate CSI feedback from stationary relay station is possible enabling advanced non-linear precoding schemes.
• High rank MIMO transmission will not be effective due to higher probability of Line of Sight (LOS) channel from Macro to Relay

CoMP is still probably the most promising spectral efficiency solution but need to focus on closing the gap between gains predicted by theory and those achievable with current LTE Release 8 Feedback Schemes

Interdigital's 'Fuzzy Cells' technology for cell edge performance improvement

Back in LTE World Summit 2010, I heard from Dr. Ariela Zeira, InterDigital's Vice-President of Advanced Air Interfaces about various things Interdigital have been working on.

One of the technologies that caught my attention was Fuzzy Cells technology to increase the cell edge rates. The following is from their press release for Mobile World Congress:

BARCELONA, Spain, Feb 15, 2010 (BUSINESS WIRE) -- InterDigital, Inc. today announced the demonstration of its "Fuzzy Cell" technology that improves cell-edge performance at the 2010 Mobile World Congress. The Fuzzy Cell technology is part of the company's comprehensive suite of "Next Generation Cellular" (NGC) innovations that combine advanced network topologies and spectrally-efficient air interface solutions for LTE-advanced and beyond.

"Many wireless operators and customers are experiencing a substantial degradation of service quality caused by the ever-growing demand for mobile data," said James J. Nolan, Executive Vice President, Research and Development, InterDigital. "We are at the forefront of developing solutions for more efficient wireless networks, a richer multimedia experience, and new mobile broadband capabilities that support operators to capture revenues from the boom in smartphones. The Fuzzy Cell fits nicely within our much broader efforts on spectrum optimization, cross-network connectivity and mobility, and intelligent data delivery techniques."

While cellular networks have become virtually ubiquitous, users continue to experience inconsistent and unpredictable performance when moving around. While this degradation is often the result of network congestion or an obstructed path of the radio waves, it is also inherent to traditional cellular deployments, whereby signals degrade towards the fringe of any given cell due to interference from neighboring cells. It is estimated that typical users experience this situation, known as being in the cell-edge, more than 50% of the time. Advancements in HSPA and LTE primarily increase peak data rates and only offer modest improvements in average performance throughout a cell.

Fuzzy Cells is a novel approach for leveraging existing resources to improve spectral efficiency and cell-edge performance. In a traditional deployment a device connects to one site at a time (even if multiple sub-bands are used at each site) and all sites use the same power levels and sector orientations for all sub-bands. In a Fuzzy Cell deployment, a device may connect to multiple sites at a time through the different sub-bands and continue to realize full system bandwidth. The power levels and sector orientations of the different sub-bands are optimized for best performance. In simpler terms, the device exploits the best combination of base station support regardless of its position, removing traditional limitations of cell or sector boundaries. Importantly, Fuzzy Cell technology can also allow gains indoors as it allows connection to more than one cell/sector at a time as available. The Fuzzy Cell technology provides additional improvement over Fractional Frequency Reuse (FFR) methods that are supported by current specifications.

The following shows the demonstration of Fuzzy cells:

I haven't heard any news recently on this technology but its an interesting concept, not sure if it would be adopted in the near term in the standards.
