Poor image quality with mobile broadband

Some of you may have noticed that when you’re browsing the web with mobile broadband that your image quality is poorer then when you use normal fixed line broadband. This is due to optimisation by Vodafone – they’ve got a box in their network (supplied by a company called Bytemobile) that intercepts web requests and optimises them to reduce the size of the request so that web pages load faster and use less bandwidth on the network.

This optimisation is done at a number of levels, but the most noticeable is the lossey compression applied to images. This means that the size of the images you download are much smaller than the original file, but the quality suffers – resulting in blocky, fuzzy or grainy images. The technical name for this is ‘compression artifacts’ – see http://en.wikipedia.org/wiki/Compression_artifact for more details.

Improving Image Quality

Quick Fix
There’s a number of ways you can improve the image quality on a web page, the easiest is to hold down shift on your keyboard whilst clicking on the refresh button in your web browser. This will cause your browser to send a ‘no-cache’ header – the optimiser sees this header and sends the original, untouched web page to your browser. This fix however doesn’t work on Safari.

For the nerds out there I’m pretty sure you can tinkle with Firefox’s headers via a plug in and force the no-cache header to be sent every time.

Windows Client
If you want a more permanent fix, you can download the full Vodafone dashboard client from here . This software includes the Bytemobile optimiser client, and allows you to change your optimisation settings.

Once you’ve installed the client, click on settings, then optimisation. On this screen you’ll find the option to set the image quality to ‘highest’.

Mac OS Client
ByteMe There’s no official client for Mac OS users, however the guys over at http://aitne.com/ have created an app called ‘ByteMe Optimizer’. This tiny little app runs in the background and kicks the Vodafone optimiser into returning uncompressed pages.

Vodafone simplifies mobile broadband approach

Here’s a press release from Vodafone UK: 

This summer Vodafone UK will begin a multi-million pound investment to extend its fast and reliable mobile broadband network to a further three million people across six major conurbations; Birmingham, Bristol. Glasgow, Liverpool, Manchester and Reading. These towns and cities join London and major British airports, which were the first locations to benefit from Vodafone’s high speed upgrade in 2007. Roll out is expected to be completed by Autumn 2008.  This summer will also see Vodafone start to do even more to simplify the way it sells mobile broadband services to customers.

Since pioneering Mobile Broadband in June 2006, Vodafone has led the way in keeping things simple and through innovation and customer insight1 has introduced the following key elements; the award winning USB modem2, plug and play software, flat rate domestic tariffs and ‘per day’ roaming sessions with Mobile Connect Abroad. Customers can also be assured of the fastest, most reliable network, as recent independent trials3 consistently show Vodafone leading in these areas.

From June, Vodafone customers will see a change in the way Vodafone UK sells Mobile Broadband. Vodafone UK will do even more to help customers make the most of the service, providing more information that reflects the way customers actually use the network.

For example, customers can expect to see more information at the point of sale to help them understand the time it will take to download files, films and music on the mobile broadband network4. The number of emails a customer can expect to download or the number of web pages they can browse will also be more clearly illustrated. Details will be made available in store, online and through our contact centres from June.

“The recent acceleration in the take up of mobile broadband has demonstrated just how hungry consumers are for internet access wherever they are.  As a result we are significantly investing in our network so that more customers can experience our award winning, fast and reliable mobile broadband network,” said Nick Read, CEO of Vodafone UK.

“We are committed to keeping life simple for our customers in terms of access to information about services and speeds, keeping pricing clear, as well as ensuring our device range comprises easy to use, plug and play modems. From June we will focus on providing additional relevant information with details on everyday usage scenarios, which will ensure customers can continue to make the most of Vodafone’s  high speed mobile broadband service,” continued Nick.

Today’s news builds on an announcement5 made in April by Vodafone UK that it has signed a five-year agreement with BT that will give Vodafone the capability to deliver the highest performing mobile broadband experience for customers. The agreement will see BT deploy its new 21st Century Network-enabled Ethernet service. This will enable Vodafone UK to manage the predicted growth in traffic and bandwidth requirements without the need for further investment. (see link to full press release)

Problems with the E870 ExpressCard on certain machines

It looks like there have been some compatibility issues between the Huawei E870 ExpressCard where the card will not power up correctly (normally resulting in the LED indicator going a solid colour as soon as it is plugged in or no lights at all). This has been seen on certain models of Advent, E-Systems, Fujitsu Siemens and Dell machines to name a few.A new firmware for the card (not a VMCLite Update) has been released to resolve this which can be found here: E870 Firmware Update  It looks like this can be applied on the machine its failing in as long as the Huawei 3G PC UI Interface device component is visible in Device Manager under Ports.cheersSimple

Huawei E220 - 7.2Mbps firmware update

I’ve just got my mits on the latest firmware for the Huawei E220. This update upgrades the modem to download at speeds up to 7.2Mbps - compared to the standard 3.6Mbps. I’ve just installed it and run a speed test in a 7.2Mbps area and I’m getting average speeds of around 2.5Mbps, peaking at 4.3Mbps (see the NetPerSec screenshot). The lack of receive diversity on the device will prevent it from hitting speeds much higher than this.

E220 7.2Mbps

This firmware isn’t an official release from Vodafone, so don’t expect any support from them… The usual disclaimers apply here - if you want to install the update do so at your own risk…..

Download firmware 11.117.09
