Cool-Tether Links Phones' Bandwidth To Make High-Speed Hotspots

Barence writes "Microsoft Research has found a novel way of beating the deplorably slow speeds of mobile broadband, by combining several phones together to make one high-speed hotspot. Dubbed Cool-Tether, the system harnesses the mobile data connection of multiple mobile handsets to build an on-the-fly Wi-Fi hotspot. 'To address the challenges of energy efficiency, Cool-Tether carefully optimises the energy drain of the WAN (GPRS/EDGE/3G) and Wi-Fi radios on smartphones,' Microsoft's research paper claims. 'We prototype Cool-Tether on smartphones and, experimentally, demonstrate savings in energy consumption between 38%-71% compared to prior energy-agnostic solutions.'"

Mobile operators will just love this! Considering the cell towers can be a bit slow already and especially so when many people are using them for internet, this will not magically provide better speed off it. But it lets users abuse the network same way that BitTorrent does - hammer the network so much that you get more while others suffer.

While operators already have unlimited 3G for cheap (not in USA, so they actually are unlimited), the only way slow speeds of mobile broadband is going to improve is to push for new technologies and make the operators improve their network. But not that 3G's 5Mbps would be that slow anyway.

I was actually thinking of something like this yesterday. With the rapid increase in Wifi + Internet enabled phones and devices, it could be possible to actually have an entirely distributed network just by linking together devices in range.

Perhaps that's where we should build the Internet 2, now governments around the world are doing everything they can to control the first one. :)

Using bandwidth that you have PAID for is not abuse. A company overselling their capacity or promising more bandwidth than they provide is fraud however.

But, but.......

Everyone here knows Microsoft cannot innovate!

Good job

Microsoft Research has found a novel way of beating the deplorably slow speeds of mobile broadband...

Good job, research division. Now reluctantly hand it over to marketing which will:

- Tie it to Windows Mobile
- Cripple it to only work with Hotmail and Bing
- Junk it up with "partner channels"
- Drag out deployment long enough for Apple to be able to field something smaller, cooler and 5x more expensive six months ahead

that's why there's no simple UI for configuring it

Well, for many people, they cannot do anything on a computer with out the "simple UI". So bringing something that a very small population knows how to do on a OS that most have not heard of to the general population might be something worth doing.
