Goals: 100 Mbit/sec for 50 users
We decided to use a commercially-available RF modem even though it
deviates substantially from the long term plan for the InfoPad
wireless link described in [She92, She94]. The link for the IPGraphics
prototype used a half-duplex, 1 Mbps RF modem: the DE6003, from GEC
Plessey. It was chosen because it had the highest data rate of
commercially available radio modems, in a form factor that we could
place in the IPGraphics unit The DE6003 (Figure 4) provides a
demodulated signal to the baseband receiver, implemented in a Xilinx
4000 FPGA, without any explicit timing information or attached

The AirShare modules are about the size of a pack of cigs. One is AC powered
and attaches to the serial port of the fixed-device (like a desktop PC, or for
me, a modem). The other can either be powered by an AC adapter, a little 9V
battery, or if your mobile device supports it, a PS/2 mouse-port. It also
attaches to the serial port. You can select one of three different
communication channels (for up to three machines you wish to talk to). It
uses frequencies up in the 900MHz range, supports up to 115K bps, and
distances of up to about 30ft.
A 27 page Acrobat datasheet is available at:
in the "Communications, Wireless" directory.
Contact firstname.lastname@example.org for any questions about the modules.
They are sold in sets by Traveling Software. The set contains two
modules, a battery pack, PS/2 mouse/kbd 'piggy back' power adapter and

Infrared Data Association
Last year, a consortium of industry leaders, the Infra Red Data
Association, agreed on a standard for infrared data transmission,
Protocol 1.0. This low power standard transmits data at speeds up to
115.2-Kbps within a three-meter range. To implement the protocol, IrDA
estimates it will only cost $2 to $4 per unit.

October 16, 1995
What PC Week Labs learned when we cut the 10BaseT cables and went wireless
By Terry Tam
Wireless LANs cut traditional wired ties between a workstation and hub, bringing mobility to movers and shakers and forcing a paradigm shift in how IS managers view their world.
Not to be confused with the more popular cellular modem market (linking to RadioMail or WyndMail, for instance), spread-spectrum wireless technologies are designed for connectivity to a LAN or for the...
Wireless LANs provide the same benefits of continuous connectivity to the corporate backbone as cellular modems, only a wireless LAN rescues corridor cruisers rather than road warriors.
To explore the real-world ramifications
