Veterans Day is a special day, created to honor and pay respect to our country’s heroes. These heroes never ask for our recognition or gratitude, yet they deserve our appreciation every day. Thank you to those brave men and women who have sacrificed, along with their families, to serve our nation and protect our freedom.

Back again from hiatus. Well, we really never left. We've just been posting lots over at our official Facebook page. But hopefully we'll have finished two all new test drive reviews to tell you about. First we drove a new 2014 Volkswagen Beetle GSR, and we followed that up with a recent drive in a 2014 Tesla Model S 85. Both were very exciting. So look for those reviews later this week along with a few other stories.

This one just came across my desk and I felt this one was worth of posting here as I, and many others in our office are Cannonball Run, Gumball Rally, Bull Run, etc fans. Ed Bolian, a Lamborghini dealer from Atlanta, Georgia. is such a fan of the infamous Cannonball Run events, that he once told Brock Yates that he planned to break the record. This was before Alex Roy setting the previous record of 31 hours and 4 minutes in his ultra modified BMW M5.

I guess we should say what the new record is. Would you believe, 28 hours and 50 minutes? Shattering the previous record by about 3 hours. Very impressive, but also extremely dangerous. Bolian's choice of equipment was a 2004 Mercedes Benz CL55 which like Roy's BMW was equipped with several navigation units, and a host of radar detectors and monitoring equipment. And the run was made with co-driver Dave Black and support passenger Dan Huang. So, a pretty comfortable ride for 3. During the run, their top speed was 158 miles per hour with an average of 98 miles per hour from the Red Ball Garage in New York City and finishing at the Portofino Inn, in Redondo Beach, California. The original start and finish of the Cannonball Runs. The only thing that I personally didn't agree with was releasing the details about the run this soon. Alex Roy waited nearly a year before releasing the details of his run so that the statute of limitations would expire. Bolian's run was just made on October 19th. And he only waited about 10 days to release the news. But either way, the record has been broken. I wonder who will break it next, and more importantly, with what car? Congrats go out to the team. But we do caution our readers. If you have the need for speed. Please, take it to the track.

Thinfilm based out of Oslo, Norway, has developed a method of using specialised inks to print smart electronics onto labels, the first of which is a temperature sensing label for monitoring the temperature of perishable goods.

The labels are thin and flexible, contain the sensors, batteries, display and memory, connected by printable ink. This also means they can be both manufactured on continuous roller production lines and then placed on goods using roller systems to remove the labels and place them.

It is expected that the market for thermo sensor labels will be over $3.2 billion USD by 2020.

The technology uses full addressing logic for multi-bit read-write of printed memory, memory write based on detection of temperature thresholds and low-voltage display driver based on complementary organic logic. The memory should remain readable for at least 10 years.

Products based on the combination of these technologies is expected to be market ready by the end of 2014.

Printable electronics can significantly reduce costs and will permeate many areas that currently use discrete electronic systems that are more expensive and not suitable for rolling production.

There are also many other uses that can be used for the Internet of Things.

Last week LinkedIn introduced a new iOS app called Intro. It seems a really good idea by scanning your email and showing how the person sending the email is connected to you, their LinkedIn details etc.

Unfortunately it does this by modifying the iOS mail connection profiles and pointing them all at a LinkedIn's IMAP proxy, thus intercepting ALL your email. This means that LinkedIn suddenly have access to all your email accounts and also every email that your iOS device has access too and of course they'd never do anything sinister with all this data (forget the NSA and GCHQ tapping emails, this is LinkedIn doing it with your permission).

Of course LinkedIn strenuously deny that they're doing anything dubious and their IMAP proxy is heavily secured (including connections to and from it using SSL/TLS), however it must suddenly be a great target for hackers as within the proxy itself all emails will be at some point held in clear-text.

Various mail providers are already looking at blocking LinkedIn's IP blocks to their mail services (listed below).

Nice try, just be scared.

A couple of weeks ago I was lucky to invited to test ride a SMART e-bike. There are some things I should point out: -

• I'm not really a bike rider
• I haven't properly ridden a bike for many years
• Riding through London terrifies me

However saying that, the e-bike is pretty, we used the white and green version (it also comes in grey with orange trim - which I thought looked prettier).

The bike is quite heavy (though having an aluminium frame, and the metal drive chain replaced by a carbon-fibre drive pulley), it weighs 26.1Kg. It comes with hydraulic disc brakes front and rear (and mud flaps). The seat is quite comfortable as it contains a gel liner to pad your sensitive bits. There's also an air shock absorber on the front section (which is adjustable) to smooth out those bumps.

In the rear wheel there's a 250W brushless DC motor that can move the bicycle up to 15Mph.There's also an 'automatic' gear system (from 1 to 3 where 1 is the easiest and 3 is the least gearing).

The rechargeable battery (mounted in bit that the seat fits on to) is lithium-ion 48V with a capacity of 423Wh which can be removed. It comes with a normal mains charger (that can charge the battery in situ) and a full charge takes around 5 hours. The battery is guaranteed for 500 charging cycles and will retain 80% residual charge for 2 years. The management unit also has a USB port (for diagnostics/software upgrades/etc) and can also change a device like a smartphone, useful with the optional smartphone holder that mounts in-front of the unit allowing a user to use GPS/maps/etc.

There's also a display mounted between the handle bars that is the 'brains' of the e-bike. It has a trip counter, shows the battery charge remaining, speed and also the amount of power applied to the motor (from zero to 4 units at max power). The unit can also put the motor into charge mode (from -1 to -4) where the the motor will then act as a brake.

When riding from stationary, the motor won't actually kick in until the pedals have completed around 2 revolutions, this is to stop the bike say lurching forward when traffic lights go green, straight in to the back of a vehicle in front.

Riding isn't effortless - a rider still has to pedal, though when the motor kicks in it;s certainly easier riding. Also when climbing a steep hill, putting the e-bike into low gear and turning on full motor assist does make a life a lot easier.

If then going down a hill, put the motor into charge mode and as well as the motor acting as a smooth brake, it also charges the battery. The battery is also charged when the front-brakes are applied (i.e. the motor assists with breaking).

I managed a ride of 13.9 miles in about 4 hours (with a break) and wasn't particularly sore afterwards (apart form soft fleshy bits, but that's just not being used to bike parts rubbing me). It really did make riding easier. The bike has a range of 60 miles (I'd assume normal road riding conditions), though this will vary depending on how much the motor is used and how much the motor is used as a brake (which will charge the battery).

There was one major flaw with the bike, the controls for the management unit are on the unit itself, when they should have put them near the handles of the bike (maybe an extension system). Changing the controls meant taking your hand off the grip and fiddling with the control unit, which isn't the safest thing in the world.

The bike is also heavy, so manoeuvring at slow speed (like going through cycle gates) was hard as it meant moving a heavy bike and trying to navigate odd turns etc. and at low speeds 9without pedalling) you're on your own.

The e-bike isn't cheap, it costs £2,600 without any of the accessories - coming from Mercedes, they're not cheap either.

NOTE since writing this SMART have updated the e-bike and put the controls for the management unit into the handlebars, they've obviously listened to feedback fro early users. Maybe the next version will be made out of carbon-fibre and thus reduce the weight too.

TomTom Business Solutions is launching a new device the TomTom Link 100. This connects to the engine management unit (EMU) via the standard CAN-bus and has a built in 3D accelerometer. This then can connect to a smartphone device via Bluetooth allowing easy diagnostics in the event of a crash or even the vehicle breaking down.

All modern cars use the standard bus interface so it should work will most cars on the road.

The device can also be used by insurance companies to track driving habits etc (though no GPS information is available), drivers could also use the device to improve their driving.

TomTom have not said what data is exposed (apart from RPM, load and temperature), though the EMU provide a lot more information and with the right application many minor faults can be reset by such a device making trips to the garage less frequent (and also allowing drivers to check what faults garages etc are charging them for and whether it is a major or minor fault).

If the all the data is exposed and TomTom allow read and write information it could allow app vendors to make interesting solutions to make the driving experience better, though of course insurance companies will want these devices to ensure drivers drive better.

Ofcom, the Super regulator that has responsibility for spectrum allocation, is consulting on the planned release of MoD spectrum in the 2.3GHz and 3.4GHz bands.

The bands being made available are 2350 to 2390 MHz (40MHz) and 3410 to 3600 MHz (150MHz). It is expected that these bands will be licensed for use by mobile network operators for 4G/LTE services, though other broadband services could also be offered.

Unfortunately these bands are also used by amateur radio and it is likely that severe interference can be expected. Therefore Ofcom has proposed three recommendations to minimise interference.

• i) Remove access to the adjacent bands
• ii) Retain access to the adjacent bands on the current terms but with clarification of the notice period required for future amateur use to cease if amateurs cause interference to other users in the release band or the adjacent band
• iii) Restrict amateur access to a smaller part of one or more adjacent bands.

Of these 3 Ofcom's preferred option is ii) whereby Ofcom will require amateurs to stop using these bands if there is interference to licensed users (with a notification period).

Ofcom wants to make changes to amateur licenses such that if the proposals are accepted would

• i) remove the frequencies of the release bands from the licence.
We have set out three options for the adjacent bands and are recommending option two which if implemented would:
• ii) introduce a procedure to enable removal of additional frequencies (i.e. the adjacent bands) to quickly if harmful interference arises in the future.

Though this will adversely potentially affect amateur radio users, the benefit to the overall population will be increased with access to more spectrum for LTE or other services.

The consultation has now closed.

Ofcom, the Super regulator that handles radio spectrum as part of its remit, is holding a consultation on the coexistence of whitespace devices.

Whitespace is the spectrum that is unused in certain areas due to geographic transmission systems that can not overlap and in this case relates to the UHF TV channels (470 MHz to 790 MHz). As there are multiple transmitters across the UK, adjacent transmitters can not operate in the same frequency bands (especially for digital TV) or the transmitters would interfere with each other.

This leads to large chunks of the UHF spectrum not being used in a particular geographic zone, which could be used for other purposes (as long as it was low power and didn't reach neighbouring areas).

Current plans are that whitespace devices will monitor what bands are in use (by listening to those frequencies) and thus not use them, in the UK they must also contact a central database, report their location and the database will specify what frequencies are available and what power they can transmit at.

There are other services that can also be interfered with such as program making and special events (PMSE) - things like outside broadcast units which can use some of the spectrum for remote TV cameras and such like, which also have to be catered for.

Ofcom have already said they will allow whitespace use on a license exempt basis, but they also must ensure that there will be no harmful interference to digital terrestrial television (DTT) and PMSE.

Whitespace technology is new and thus there is some uncertainty on how whitespace devices may interfere with DTT or PMSE services. However Ofcom doesn't want to overly constrain whitespace use such that large amounts of spectrum go unused, or that power levels/etc are so restrictive that reaching any sizeable population is unrealistic.

Ofcom will currently err on the side of caution and setting parameters that can be relaxed in future. Later this year there will be a set of pilot trials across the UK with a number of service providers where the increased power levels can be used for limited periods of time to ensure interference doesn't occur. The trials (and stakeholder consultations) will continue until Summer 2014 and will help Ofcom set the parameters for future national whitespace roll-outs starting in Q3 2014.

Ofcom has set the parameters and algorithms for use in trials to minimise the effects on

• Digital Terrestrial Television services
• licensed users of equipment for Programme Making and Special Events
• services above and below the UHF TV band.

Ofcom have also noted that whitespace availability will vary in areas across the UK i.e. London has relatively low DTT issues with whitespace use while Glasgow has much less spectrum available, however Glasgow has very little PMSE use while in central London (and areas like Wembley Stadium) there is a large amount of use.

Though it is yet early days, whitespace spectrum should allow high bandwidth services with good propagation characteristics (coverage) which could be used to provide mobile network operator capacity off-loading, broadband and machine-to-machine (M2M) services.

Companies such as Neul (a CSR - now Samsung spin-off) are betting their futures on whitespace.

The consultation closes on 15 November 2013 and stakeholders can respond on-line.

Ofcom, the Super regulator that looks after spectrum management is holding a consultation on proposals to change the management and authorisation approach used to manage the bands 71 - 76 GHz and 81 - 86 GHz (70 / 80GHz). These offer 2 x 4.75 GHz of bandwidth allowing very high capacity links (over 1Gb/s) which are not supported in lower frequency bands. These bands have been available for use since 2007.

Currently the spectrum is not managed at is up to the users of these bands to co-ordinate amongst themselves on use (self coordinated spectrum), though currently use of the spectrum is minimal compared to lower frequency bands. However with the rapid adoption of 4G services and the bandwidth that will be required to remote cell-sites, usage can be expected to rapidly increase and operators are now worried that self-coordinated management will not suffice as links in these bands will have to provide 99.99% to 99.999% availability, so any interference could be disastrous for mobile networks.

Ofcom is proposing to manage the spectrum in a mixed manner offering partial self-coordinated use and partial managed use.

Ofcom coordinated approach: 2 x 2 GHz

Guard band: 2 x 250 MHz

Self coordinated approach: 2 x 2.5 GHz

NOTE Image (C) Ofcom.

This will allow non-critical links to be operated as now in the higher part of the bands while more critical services will be in the lower part of the bands managed by Ofcom (using the same regulatory environment as for fixed links in lower bands).

This should be good news for users and backhaul links get very expensive very quickly and can limit the growth of a mobile network (in terms of coverage), so being able to use protected spectrum to maintain high bandwidth links to cell-sites and allowing the networks to provision more 4G cells.

The full consultation is available on-line and stakeholders may respond here, the by 5th October 2013.

Qualcomm the company that makes chips such the Snapdragon and Powerline electronics (after acquiring Atheros) has sold it's mobile tracking unit Omnitracs to Vista Equity Partners for $800m. Omnitracs makes vehicle tracking systems that are used for fleet tracking and other automotive solutions like for consumer insurance systems (i.e. the insurance company can track the user's driving behaviour).

Orb Networks offered the free media streaming service MyCast as well as Orb Live along with the Orb TV and Music MP-1 devices. These will all be discontinued. It's assumed Orb services will be integrated into the Atheros media and home automations lines (such as Powerline and other devices).

Ofcom, the Super regulator, is holding a consultation on how local numbers must be dialled in 5 areas which are running out of local numbers.

The areas affected are Aberdeen (01224), Bradford (01274), Brighton (01273), Middlesbrough (01642) and Milton Keynes (01908). In these areas, the full number (including the area code) will have to be dialled - which will allow around 200,000 new numbers to be made available in these areas, which should satisfy demand for at least 10 years.

The change means the affected areas will use closing local dialling and will allow numbers starting with 0 to be issued i.e. for Aberdeen numbers will be able to be allocated like 01224 0XXXXX and 01224 1XXXXX. If the area code 01224 was not included there could be clashes with numbers starting with 0 or 1 such as 100 for operator assistance or 118xxx directory enquiry services.

The consultation closes on September 13th 2013 and the change is expected to come into force in October 2014.

Ofcom's statement is available here and stakeholders may respond on-line.

Ofcom, the Super regulator that looks after radio spectrum management and broadcasting amongst other things has reported on a trial that used open source software to run a digital audio broadcast (DAB) transmission.

The trial was based in Brighton and used Linux software and an software defined radio (SDR) to broadcast DAB signals in the Brighton area, though the trial was only low power (the output of the SDR was set to 5mW) a signal could be received over 7Km away. There was also no detectable interference to the BBC local DAB multiplex which was around 3Km away from the trial transmitter.

The trial was carried out privately under Non-Operational Test and Development licence issued by Ofcom.

The full report is here, Ofcom doesn't endorse any software or hardware used, but the report contains references to all the hardware and software used.

Initially the trial was conducted using 2 laptops, but the software was integrated on to a single (rack mount) PC running xubuntu. It would also be possible to run at least some of the software (multiplexor etc) on a RaspberryPi.

Maybe this will lead the way for other Ofcom 'approved' trials such as running lower power GSM networks also using open source software.
