coondoggie writes "Later today IBM plans to announce microprocessor chipsets that can wirelessly transmit high-definition video at extremely high speeds. 'IBM will do this by teaming with MediaTek to launch a joint initiative to develop these ultra fast chipsets.The companies will be developing millimeter wave (mmWave) radio technology — the highest frequency portion of the radio spectrum — 60 gigahertz rather than 2.4 gigahertz — and digital chipsets that enable at least 100 times higher data rates than current Wi-Fi standards.'"

This makes it pretty nice for a lot of uses, since it removes much of the potential for interference. A good use-case for this kind of technology would be your pocket computer talking to your TV for display when you were in your home. Throw in a wireless keyboard and pointing device and you've got an ideal pocket computer. With that much bandwidth, you can also talk to the NAS hidden in your basement with access points in each room.

Most 54Mbps wireless networks do max out at about 30Mbps, but not for that reason. You miss out on the max speeds because of overhead from the 802.11 protocols and interference, not so much because it's flipping directions. If you've got 802.11b clients in the area, it can get even worse, dropping an 802.11g connection down to a practical throughput of about 15Mbps.

Checkout my idea:
We know power lines can carry data. So, you buy little transformer-like devices that take this wireless video signal, transform it and beam the data in the power network.
Then you take another such transformer, and plug it in any socket at all in your house, or house around you even, which beams the data back to 60 GB wireless signal which hits your laptop, tv, console etc.
Achieved benefits:
1. no wires
2. works through walls
3. gigabits of bandwidth for your video and net
4. potentially getting brain cancer and dying young, but that's not important.

Personally.. I like cables for hooking up video. Wireless is buggy, snoopable, power hungry, and hard to set up (with 4 transmitters and 4 receivers, how to you configure what displays where?) Cables, while bulky and sometimes annoying have an incredibly easy UI. Plug one end here, the other end there, the things are connected. Want to change it? plug the wire in somewhere else.
