Improve Tmobile USB Mobile Broadband, PDA, Smartphone or Tether Picture Image Quality

Improve Tmobile USB Mobile Broadband, PDA, Smartphone or Tether Picture Image Quality The problemFor the past year or so I have relied heavily on a T-Mobile broadband dongle for when I am out and about. Generally the speed has been OK – at least 1mbps when signal is good – though I have seen it as high as 4mbps at times. One thing that I noticed, as I am sure you have, is that images viewed when using Tmobile service are actually a lot ‘blockier’ and of lower quality than they would be if you were viewing from a home or work broadband connection. This is not down to the fact you are using mobile broadband at all, this is down to the way T-Mobile run their network using ‘interception and dynamic image compresison’. CompressionMost images you view on the web today are what are known as ‘compressed’ images. This means that some quality is sacrified in order to download the image to your browser quicker – but not much quality as you can still see the image just fine. In fact, you may not even realise or know an image has been compressed at all. Re-compressing interceptionTmobile, however, have taken things a step further. If you view an image on a web site, tmobile actually intercept that image within their network – as its going from the server to your mobile broadband – then then add much much more compression to the image, which makes it smaller and quckier to download. This is not just Tmobile being nice to give their users a better experience – all those millions of images a day use up a lot of tmobiles network bandwidth. So tmobile add this extra compression to improvee the time in which pages take to load for you and also cut down on the amount their network is used, while sacrificing the quality of the images you see (sometimes quite a lot of sacrifice!) Is it useful? On slower connections (such as GPRS / 2.5g) or when you have a small ‘fair use policy’ on your mobile broadband, this image compresson can actually work to your advantage by making pictures load faster, and keeping the bandwidth down. Though having said that, on todays faster mobile broadband connections (3g, 3.5g, 4g), when you see an image, it is likely that you will want to see it as the website publisher intended – in the original quality. In fact, on faster mobile broadband connections pages can actually load slower with this intercepting recompresison than they would without the compression – imagine the extra time it takes for T-mobile to intercept the image and re-compress it before your browser can display it. Another issueLets say you visit www. somesite. com from your mobile broadband connection. Tmobile add their extra compression to the images and your browser ‘caches’ the images incase you re-visit the site later on. this means your browser is storing very low quality images in its cache. So now you connect to your home/work broadband or other Wifi and re-visit that same site. You will see the lower quality images still as the browser has stored them in its cache from the tmobile connection. EEK! How I fixed itI simply went to Be aware that the titles tmobile use are a bit misleading. It can actually take longer on a 3g/3.5g connection to download a re-compressed image than it can to download the original copy without the compression so im not sure why they say ‘lower speed’.
