NVidia has upgraded it's all-in-one system-on-chip the Tegra4i to support Category 4 LTE before it's even been commercialised.

Category 4 LTE supports 150Mb/s download speeds and is already being implemented by other vendors.

This should give NVidia a better chance against its main competitors (in the Smartphone markets) Qualcomm, Broadcom and LTE-only specialist Altair.

NVidia gained LTE experience by acquiring UK company Icera which uses a software defined architecture and though this technology has been used alongside Tegra4 CPU devices as a separate package, the Tegra4i integrates the technology on to the system as the Tegra4. As Icera's technology is software defined, no actual hardware modifications were required to implement the enhancements.

Currently no mobile networks actually support Category-4 LTE (or LTE Advanced), though Japan's NTT Docomo has said they'll be announcing services by the end of the year.

Qualcomm last year said it was not pursuing direct sales of it's colour e-ink solution Mirasol and would license the technology to partners.

Mirasol uses MEMS (micro-electromechanical systems) technology and is very low power, works in direct sunlight and low light conditions though it has been criticised for washed out colours.

At the SID Display Week event in Canada last week, Qualcomm seems to have reversed its decision and was very publicly displaying the latest version of the Mirasol technology and said it could appear in devices with small screens later this year (less than 1.5 inches - speculation is on some form of smart watch).

There was also a demonstration of a 5.1 inch screen with a resolution of 2560x1440 which equates to a pixels per inch (ppi) value of 577, while Samsung's Galaxy S4 has a resolution of 1920x1080 with a ppi of 440.

The Mirasol technology is really nice and it would be a shame if Qualcomm didn't maximise its market position and push the technology out soon.

Both EE and 3UK won 2 x 5MHz chunks of 800MHz spectrum in the recent UK spectrum auction for deploying LTE/4G mobile services. O2/Telefonica and Vodafone both won 2 x 10MHz chunks (with O2 having a coverage obligation).

EE currently has deployed LTE in their 1800MHz spectrum and they will relinquish some of this (2 x 15MHz) to 3UK by the end of 2013 when 3UK can deploy their own LTE services.

Generally the minimum requirement to deploy LTE is a requirement of at least 2 x 10MHz, so the two lots of 2 x 5MHz may cause EE and 3UK issues, so they are considering joining their efforts and sharing their joint spectrum, giving them access to a joint amount of 2 x 10MHz.

Currently this is just in the planning stage and it may not be technically feasible, though there is no reason why it shouldn't be.

Perhaps best known for much of his work that was claimed by George Barris, Dean Jeffries was one of the most legendary men in automotive culture. He was the complete package. He was a metal worker, a painter, a designer, a car builder, stuntman. He did it all. I mean, where do you begin?

Jeffries was born in Lynwood, California in February 1933. He had dreamed of attending the Art Center in Pasadena, but instead of doing well in school he gravitated toward cars like most teens do, learning from his  father who was a mechanic. While stationed in Germany during his stint in the Army, he learned the art of pinstriping from a furniture and piano striper, and upon returning home to California, he continued to learn from Kenneth “Von Dutch” Howard. This landed him a  job as the in-house pinstriper for George Barris. Along the way, he learned how to shape metal, as well, and began to take the customization of his clients’ cars further; during that time, he not only striped James Dean’s infamous Porsche 550 Spyder with the nickname “Li’l Bastard,” but also built Chili Catallo’s 1932 Ford three-window coupe, the one that the Beach Boys used on the cover of their Little Deuce Coupe album.



Jeffries also did work for Caroll Shelby. He painted the first Cobra as a favor to Shelby. He sympathized with Shelby’s effort to get the car done on a budget. “The body was a disaster, all heliarced and torched up. I had only three days from start to finish. I asked Shelby what color he wanted, and he said, ‘Any color you want.’ So, not knowing if it was right or wrong, I painted it pearl yellow because I had heard on TV that yellow stood out the best.” Shelby would later provide Jeffries with a Weber-topped 289-cu.in. Ford V-8 and four-speed transmission for Jeffries’s Mantaray, an asymmetrical single-seater based on a 1939 Maserati 8CTF Grand Prix chassis.

After leaving Barris' shop. Jeffries set up shop in Hollywood. This attracted plenty of celebrity clientele and made way for jobs creating and customizing cars for the movies and for the stars, including the Monkeemobile, the Chrysler Imperial based Black Beauty from The Green Hornet television series, and the Landmaster from Damnation Alley. He didn’t restrict himself to Hollywood cars, however: He also designed and manufactured the Kyote Volkswagen based dune buggies and built a number of custom and concept cars for Ford Motor Company, including a gullwing-door show car called the Cougar, the Falcon Python show car, and the Ford GT40. He also did some construction and painting for several Indy Car teams. 

Jeffries also worked for a while as a stuntman. During the production of Honky Tonk Freeway in 1980, Jeffries performed a jump stunt with a truck in which he broke his back. He also performed stunts in The Blues Brothers and Fletch. What he will mostly rememberh him for if not through his cars then through his feud with George Barris, brought on by Barris’s habit of taking credit for Jeffries’s work throughout the years. “He couldn’t put a dent into something, never mind taking one out, but he’s a hell of a promoter, believe me,” Jeffries said. Barris retorted that he couldn’t “control what magazines write and who they list as the designer and builder.”

Jeffries remained very active in the industry until about five years ago and still maintained a shop in Hollywood.

Google announced on Monday 13/05/2013 that it was increasing the storage for GMail and GDrive customers to 15GB (this is shared if both are being used) and the upgrade will be rolled out over the next couple of weeks. Google App users also get an increase to 30GB as standard.

This should suit users who have say small mailboxes, but large image files or vice versa.

Customers can still upgrade and 100GB is $4.99 per month, or 200GB is $9.99 per month.

This will surely put pressure on other cloud storage providers such as Dropbox - who only offer 2GB as standard (though this can be increased by referring people and other methods to around 25GB).

Camden Council in partner ship with Arqiva will offer WiFi throughout the borough, with roll-out starting in June/July 2013.

The roll-out will take place in 3 phases, with the 1st phase covering South Camden (highest footfall), with phase 2 covering Camden Town and Kentish Town and phase 3 moving to Kilburn, Finchley, Hampstead and Belsize Park. The service is expected to be fully finished by the end of 2014.

The WiFi access points will be attached to lamp posts in streets and public places and Camden is aiming to make the borough "one of the most connected place in the country".

The first 30 minutes of access are free and following that users can elect to pay for more time, though access to Camden's own services can be accessed at any time.

Users will have to register their devices (laptops, tablets, smartphones) in order to use the WiFi, which must be in order to limit abuse which can occur through open WiFi networks.

Arqiva have a 10 year contract with Camden to provide enhanced digital services and the WiFi access points may well be enhanced int he future with 3G/4G small cells etc to offload traffic from the mobile network operators (assuming Arqiva gain access to licensed spectrum).

Camden are leading this effort which will eventually encompass 17 other Councils.

In some news out of left field. The folks from Consumer Reports have come out an announced that the Tesla Model S is bar none, the BEST car they have ever tested. Interesting because of the fact that it is a full electric car. But that's also one of the biggest reasons why CR says it's the best. Styling is uniquely Tesla, and looks like nothing else on the road. Inside, a 17 inch touch screen panel controls just about everything in the car. Now how it is better than say a VW Jetta TDI?

Well, I'm not sure other than you can take the Jetta on long road trips. The Model S can handle say Los Angeles to Las Vegas. Longer trips are possible thanks to a network of supercharged charging stations that can charge the battery from empty to half full in about a half hour. However, expect a full charge to take 12 hours using normal 240 volt home electric. That can be cut down with an optional charger from Tesla that takes about 5 hours to recharge.

Sticker price for the Model S comes in at a hefty $90,000 give or take a couple hundred bucks. And lets face it. Frankly, it's not a Prius, and that's why we like it. Even though we still prefer our cars to suck gas, not electricity.

So, while it may not fit the need for everyone, it's pretty darn close for some. Unfortunately, for those of us here in Pittsburgh, and the rest of Pennsylvania for that matter. There are no Tesla dealers. There is a service center in Philadelphia, but the closest dealer is in Tysons Corner, Virginia which is just outside of Washington D.C. That is partially due to Tesla's troubles with their store style of dealer system that has the national and state dealer associations up in arms. And that's not to mention the other financial troubles that have hounded Tesla.

Here's hoping that Tesla sticks around for a while.

The 2.4GHz band (2400MHz through 2483.5MHz) is used by license exempt devices as it's an international ISM (Industrial, Scientific and Medical) harmonised band. Common uses for this band in the UK are WiFi and Bluetooth devices.

The Government is hoping to free 500MHz of spectrum by 2020, mainly by re-allocating spectrum currently held by the Ministry of Defence (MOD). The first part of freed up spectrum is in the 2300MHz band (2350MHz to 2390 MHz) which should be released in 2014.

Though Ofcom will issue a technology neutral license, it's expected that the spectrum will be acquired for Long Term Evolution (LTE) services.

Ofcom is requesting that stakeholders in the 2.4GHz band let Ofcom know how releasing the 2300MHz band might affect them.

The statement is on-line here and stakeholders may respond using an on-line form.

The consultation closes at 5pm on the 19th June 2013.

Ofcom , the Super regulator is holding a consultation on the future of the 700MHz band (694 - 790 MHz). This band is being used for Wireless Broadband in several countries and the EU is proposing to harmonise this band across the EU for the same purpose.

The band falls within spectrum used for Digital Terrestrial Television (DTT) also know as the UHF band IV and V which spans 470MHz through 862MHz. After the digital switchover the 800MHz band was cleared (channels 61 through 69) and this was recently auctioned off for use by mobile network for 4G/LTE services.

The lower end of the band (channels 21 through 30) starting at 470MHz is used for interleaved spectrum, local TV broadcasts (from 2013), Program making and special events (PMSE) and whitespace services (from 2014).

The band between channels 31 to 37 - the 600MHz band was cleared as part of the digital switchover.

Channel 38 is used for PMSE exclusively and now allows high power devices in the lower end of the spectrum.

The current 700MHz DTT band extends from channel 39 through channel 60 and will also be used for whitespace services from 2014.

If this spectrum is made available for mobile broadband use, it will have very good propagation characteristics and be good for rural broadband and other uses.

Though Ofcom is consulting now, the 700MHz band won't be available until 2018 at the earliest as use of the band must be in-line with International policy.

Ofcom have produced a nice picture describing the changes.

Ofcom has a duty under the Wireless Telegraphy Act 2006 to have regard to: -

• the extent to which the electromagnetic spectrum is available for use, or further use, for wireless telegraphy
• the demand for use of the spectrum for wireless telegraphy
• the demand that is likely to arise in future for the use of spectrum for wireless telegraphy.

and using the 700MHz band falls into these duties.

Unfortunately it does mean all DTT transmissions will have to move into the cleared 600MHz (channels 31 through 37) band and the lower end of the current 700MHz band (channels 39 through 48) so in 2018 there is likely to be a second TV switchover. It's also likely that set top boxes will have to use DVB-T2 and MPEG4 (rather than the less efficient DVB-T and MPEG2 that is currently used by standard definition broadcasts today, though DTT in High Definition or HD already uses DBV-T2 and MPEG4).

The full statement is on-line here and stakeholders may respond through an on-line form.

Ofcom the super regulator is planning to hold a Whitespace trial later in the year. Whitespace is just spectrum that is not used in certain areas as it may interfere with other services in neighbouring areas (such as TV station broadcasts, the country is divided into areas such that neighbouring TV broadcasting transmitters don't use the same frequencies as their neighbours).

The unused spectrum is therefore 'wasted', but with careful management, can be used for localised services such as wireless broadband.

Neul is a technology leader based out of Cambridge (spun out of Cambridge Silicon Radio or CSR, now owned by Samsung) and already have systems available to use whitespace frequencies. Neul even have a chipset available for end-user devices.

There are (and have been) several whitespace trials, but these have been limited to localised technology trials.

One of the features that is required for whitespace to work is a centralised database of locations, frequencies and power levels. Generally there will be a central base station which will have to contact the database and report its position and it can then use that information to select the frequencies and power levels to use. End-user devices will just scan the whitespace bands and look for a carrier and can just use that as a base, from which it can then retrieve information about what other frequencies to use.

A quirk of the system is that Ofcom has mandated a kill switch so that if interference with commercial TV or other is found, all devices using whitespace can be shut-off in an area.

Ofcom has not specified how the database should be implemented, just the queries and responses that should be supported, it will be up to the market to decide how to implement. Database operators will be able to charge for running the service (again not specified, but it may be based on queries of the database).

This trial will again test the technology but also database implementations etc.

Ofcom's statement is on-line and any interested party wishing to take place in the trial can email TV.WhiteSpaces@ofcom.org.uk

Ofcom is holding a consultation as it is proposing changing the Wireless Telegraphy Act for Automotive Short Range Devices (SRDs) that currently operate in the 24GHz band in line with EU harmonised spectrum policy.

Current SRDs operate in 24 GHz (21.65 to 26.65 GHz) and existing devices in vehicles can continue to use these frequencies until 2018, however new equipment will now have to support the range 24.25 to 26.65 GHz.

The current license exemption for 21.65 to 26.65 GHz SRDs will be revoked on 30 June 2013, except for devices that were installed in cars between 1 July 2005 and 30 June 2013 in which case they can continue to use this band.

After 30 June 2013, SRDs will need to operate in 24.25 to 26.65 GHz and this band will be made license exempt.

The full statement is available here and the on-line consultation for interested stakeholders here.

Google has updated its terms and conditions so that all apps on the Play store must use Google's update mechanisms and are not allowed to directly update themselves.

This will directly affect Facebook's Android app, which had a persistent message displayed to users that a new version was available and took the user to a download link directly from Facebook.

Forcing users to only update through Google Play is a good move as it also allows Google to ensure apps can be removed from the store and thus users will no longer be able to access updates, which is especially useful if they are found to have malicious code or break other T&Cs. It also allows Google to track downloads etc.

Duedil, the site that is becoming the site to visit for company information has started offering premium payment options for access to some of it's services. It has been possible to download company reports on a pay-as-you go basis, but now it's possible to download company credit reports, official company documents, CSV financial table downloads and more using pre=paid credits. Members who subscribe are also given an ad free experience.

It's possible to subscribe on a monthly or annual basis which give the following options: -

Feature	Monthly £24.99 pm	Annual £249.99 pa
Document downloads	500 pm	unlimited
