New Wireless Technologies

Posted by ryuzaki0 on from the badger-cmdrtaco-for-a-wireless-topic dept.

Codex The Sloth writes "The Economist has an article on 4 emerging wireless technologies: (1) Smart Antennas for improved base-station capacity, (2) Mesh Networks to make each wireless reciever also be a relay, (3) Ad hoc networking to use network devices as routers, (4) Ultra wideband to transmit 100 mbs wirelessly (but only for distances of 10 feet...). Some of these are already in use while others are still in the lab."

    I mean, only ten feet? Why not just use a cable at that point?

    Synchronizing your high-capacity portable MP3 player or digital camera without having to buy a USB hub, for two. Bluetooth is one thing, but being able to move that much data in mere seconds has a real appeal.

    IANANE(I am not a network engineer), but it seems to me that widespread mesh and ad hoc networks decentralized nature might prove difficult to "police". Already we see Snort and other tools designed to break into exsisting WiFi networks. The distributed nature of these new networks would lend itself to such attacks. While strong encryption would prevent a properly configured station from being cracked, the real problem with WiFi and perhaps these new networks is foolish people leaving them wide open. Then there is the question of accountablity. What happens when my feed starts providing resticted intellectual property like "Oops!...I did it again"? Just who gets sued. Present laws dictate that ISPs are not liable as long as they take steps to immediately cut the source. Assuming, you would be protected under such a law it seems to me the central feature of the network(relaying others data) is discouraged by legal the standards.
