Barry McLarnon, VE3JF has compiled a Wireless LAN Modem Product Directory. This is a survey of wireless LAN modem products currently available.
On Phil Karn's, KA9Q, WWW page, he describes several amateur digital applications regarding digital audio and digital coding techniques.
On N6GN's Higher Speed Packet WWW Page --> --> Glenn Elmore, N6GN, describes his Layer 3 TNC Project Hardware complete with block diagrams, phasenoise and spectral plots, and information on L3TNC, which is a DSSS radio.
Lew Shannon, K0RR, lshannon@uh2309p02.daytonoh.ATTGIS.COM is pushing the edge of packet radio networking. He has a 2mbs high speed packet link working over a 1/2 mile path on 910mhz between W8PLQ and himself. They are using wireless LAN (AT&T's Wavlan) cards at 250mw using spread spectrum technology. He found it necessary to put a 33ele loop yagi with hardline up at about 45ft in an attempt to get over the trees.
They are getting a measured 98% packet reliability rate over the link. They are using the standard packet driver that comes with the WavLan cards. His JNOS 1.10i system serves as the router and bridge to the Ohio 19.2kb UHF packet network.
The 386/20 system has an Ethernet adapter which is linked to his Win95 486/66. The differences in throughput over the WavLan link and Ethernet are hardly noticeable when moving large files via FTP (it's FAST).
This was a low budget operation with hardline scrounged from a local cable company that was doing large scale conversion to fiber. The real deal was getting access to some early beta versions of the WavLan cards that were no longer needed. It's amazing what you can do when the price is right!
On Part 15 Devices WWW Page by Lee Fry, AA0JP, you can find links to information about Part 15 Wireless LAN (WLAN) and consumer devices that may be of use to amateur radio experimenters. The focus is on part 15 devices at the chip, board, or box level.
