Free mobile calls and data forever with a peer-to-peer mesh says Peep Wireless - CES

Software turns every phone into a cell-tower-free transmitter and receiver 

By Nick Flaherty www.flaherty.co.uk

This is interesting at CES in Las Vegas this week: Peep Wireless Technology has developed a software App that turns every phone into a client/server viral transmitter/receiver and creates a peer-to-peer mesh network - a mobile Skype without those vulnerable 'supernodes' if you like.
These “seed phones” then capture every device with bluetooth, WiFi or other spectrum points (ie: Game Boxes, Pads, Cafes, Bluetooth cars, PC’s, Internet TV’s, numbering over 450 million locations) and cause the Peep Mesh to grow and grow around the world in a peer-to-peer manner. The app will also be released on other phone platforms in the future.
Why might a consumer want this?: They would never need to pay a phone bill again and all their email, internet and media access would be free forever and they would control a new type of internet/mobile network, says Peep rather excitedly. An embedded social network structure pays them to use the system and transact with the App.
Why might a network owner want this?: It saves them billions of dollars and years of build-out time and doubles their capacity almost overnight. It creates instant, low-cost, femtocell, picocell and dead-zone fill-in solutions.
The entire solution is software based but Peep says it will also launch a keyfob that quadruples the range, scope and power of the PeepApp.
With the Peep technology, every mobile device connects instantly to every other unit by WiFi, Bluetooth, optical, GSM, CDMA or walkie talkie channels that the PeepApp is constantly scanning. No cell tower, base station or internet server is needed. Phone calls, media sharing, texts, movies, media and data sharing can be free between all mobile devices. All mobile units act as nodes. They transport data traffic between all the other mobile devices in clusters. Any phone call moves from one device to the next in segments, sometimes in different duplicate segments with the fastest segment of the duplicates being used until the call reaches its destination. Unused duplicate segments are discarded. This viral mesh network growth can instantly span a vast area with no external infrastructure required. The patent-issued, particulated, AES protected data reduces network logjam by its data-spraying technique.
The proprietary technology offers the ability to interact with any phone anywhere in the world for free. PWT can move across any carrier system, via a “backdoor” technology that Peep says is entirely legal - Peep devices make voice and data calls by scanning and using the entire free spectrum adjacent to them. It only takes a handful of users to cover an entire large city.

Hmm - three BIG problems I see:

  • Power consumption in the portable terminals if you are routing calls through the mesh 
  • The network operators (who own that adjacent spectrum, and if they don't then the devices can't use it, unless you use the crowded ISM or 2.4GHz bands) 
  • Until enough people download and use it it won't work very well
IMMEDIATE UPDATE:

However,  I see California is allowing access to mobile phone records without a warrant - this would be a way to keep calls more secure

Icera Triples HSPA User Data Rates & Cell Site Capacity

World's First Interference-Aware Technology Delivered on Mass Market Platform

Icera in Bristol has developed an "interference-aware" receiver technology for high speed data that can triple the effective data rate. Using signal processing algorithms in software, IceClear cancels the effect of interference from other cells, delivering up to triple the previous user data rate and cell site network efficiency. Interference-aware receiver technology has been known to achieve substantial user throughput and cell capacity gains for some time, but until now has been prohibitively complex and expensive to implement. The advantage of IceClear is to deliver this technology in software at no additional silicon cost, providing gains in user throughput right across the cell site but with particularly high gains towards the cell edge. In representative tests, where one dominant interfering cell limits user throughput to a few hundred kilobits per second, IceClear multiplies the throughput by a factor of up to 3.6 times.
Steve Allpress, CTO of Icera, said: "Mobile network operators are focusing on and differentiating themselves through the quality and consistency of their mobile broadband services. They can now look forward to delivering dramatically improved user data rates on their existing networks in a matter of weeks. This means that true mobile broadband can now be a reality for cellular users, irrespective of where in the network they happen to be."
Until now, the mobile broadband user experience has tapered from the high headline rates achieved when the user is close to the base station, to much lower data speeds at the cell edge. Previously, the data throughput has been seriously further limited at the cell edge due to interference, referred to as dominant interference power, from signals of the same frequency and of similar strength, transmitted by adjacent cell sites.
The use of current generation equalizer and diversity technology in mobile broadband chipsets materially improved user data rates compared with earlier rake receiver systems, however data rates remained poor at the cell edge in loaded networks. Hardware-based methods of cancelling the dominant interference sources require additional complex and silicon-hungry signal processing algorithms. For these cost and complexity reasons, no other mainstream HSPA chipsets have delivered interference cancellation technologies in production products to date.
Unlike any other baseband technology, Icera's Adaptive Wireless executes the entire modem in software on a specific high performance processor. This approach produces a unique flexibility to develop and implement advanced algorithms, which can adapt dynamically to specific channel conditions, in software, without the need to add any extra silicon blocks to the chip.
IceClear is included in the latest version of Adaptive Wireless.

Winners and losers in the race for the mobile Internet

Morgan Stanley's latest Mobile Internet report is ambitious. It says material wealth creation / destruction should surpass earlier computing cycles and that the mobile Internet cycle, the 5th cycle in 50 years, is just starting. Winners in each cycle often create more market capitalization than in the last. New winners emerge, some incumbents survive – or thrive – while many past winners falter.
Below are the winners, also rans and losers in the race, according to Morgan Stanley, which makes for very interesting reading. Intel and Samsung are winners, Nokia is challenged and Marvell is unclear.

The mobile Internet is also ramping faster than desktop Internet did, and Morgan Stanley believes more users may connect to the Internet via mobile devices than desktop PCs within 5 years.
