3G laptops: cheaper, faster, longer-lasting?

I wouldn’t be surprised to open a packet of cornflakes and have a 3G USB dongle fall out, they’re getting so common. They may be convenient but they’re not the most efficient way to get a 3G connection on a laptop. A notebook with a built-in antenna gets 25% better bandwidth (because the better the signal, the more data throughput you get). And given that most 3G cells have only a 1Mbps pipe connecting them to the Internet , you need all the throughput you can get.
The rumblings about EU regulation of SMS and mobile data costs carry on in the background along with OFCOM’s proposals for a voluntary code of conduct for ISPs to make sure your DSL line gives you the speed you’ve paid for, and OFCOM has also been making noises about checking out what speeds mobile broadband really offers. It’s a nice idea and it might concentrate the attention of the operators on the issue, but the speed you get depends on a mix of your handset, the Internet backhaul of the base station, how many other people are using data on the same base station - and the weather, so it’s hard to be precise.
I was impressed by the independent tests that Vodafone was trumpeting last month claiming they have the fastest HSDPA network. They’re claiming up to ten seconds faster to download a 2MB MP3 file (13.54 seconds) and four times faster to open a Web page (6.7 seconds). Anecdotally, Vodafone does feel faster than T-Mobile and Orange in the areas of London we visit, on EDGE and on HSDPA. With BT’s announcement today that it’s dropping backhaul pricing, if the mobile operators put in connections from the base stations to the Internet that are as fast as your connection from your phone to the base station, we’ll start to see which side of the network really needs to speed up.
I expect better battery life is also going to be better when you’re using built-in 3G than when you’re going through a USB port. The voltage won’t be much different but you can have much more sophisticated power management - and of course if you have a better signal, you don’t have to keep turning the radio up to try and improve things.
So Lenovo’s Centrino 2 announcements caught my eye today. Either the growth in the dongle market means Ericsson has dropped the prices of its 3G modules (scale, competition or a mix of the two) or Lenovo has decided that 3G is the best way to fight off the buzz around ultra-cheap machines like the Eee PC and Aspire One that cut features along with the price. Whichever it is, Lenovo is dropping the price premium for built-in 3G from around £100 to around nothing: from August 4th notebooks with a mobile broadband module will cost, and I quote, ”approximately the same price as those without”.
Although BT is now referring to the still-in-draft 802.11n proposal as a standard and putting it in the shiny new BT Home Hub (the rotating ten foot model of it at the BT event last night was a little scary), the n debacle drags on. At this rate, we might have HSDPA built into more laptops than 802.11n…

Sorry, The most they can install is up to 6M in the RBS 3000 base stations. The cards are costly and dont work with lost cost ADSL. Go and connect to a fast WiFi connection at a fast food joint.
