MOUNTAIN VIEW, Calif., February 3, 1992 -- Proxim Inc., a leading supplier
of wireless networking products, today announced RangeLAN, the first
family of wireless LAN adapters for both desktop and portable PC users.
All products in the RangeLAN family are based upon the same architecture
and protocols, allowing complete interoperability across the entire
product line.

The first product offering available in the RangeLAN family, called
RangeLAN/ISA, is a full-size ISA interface card that fits into a
full-length slot and includes a small antenna that extends from the
backplane of the PC. RangeLAN/ISA provides driver support for NetWare 2X,
NetBIOS and Artisoft's LANtastic networks.

The new LAN adapter card uses spread spectrum radio frequency technology
that, unlike conventional radio frequencies, does not require Federal
Communication Commission (FCC) licensing.

"RangeLAN is a cost-effective extension to existing LANs," said Paul Smith,
vice president of marketing for Proxim. "It's a complement to existing
LANs, extending them without the need for cabling to a distance of almost
three football fields. It's analogous to portable phones which complement
the conventional wired telephone network."

"RangeLAN addresses the needs of frequently changing office environments
while simultaneously serving the needs of portable users," said Smith.

RangeLAN is designed for desktop applications in situations where wiring of
LANs is difficult or impractical, such as older buildings and factory
floors, work groups which move frequently, new LAN nodes which will
ultimately be wired but need to be connected immediately and in situations
where high labor and material costs make cable installation prohibitively
expensive. In addition, portable computer users in the office who move
around during the day, and traveling professionals who do in-office file
transfers before and after trips can also benefit from a wireless LAN
solution such as RangeLAN.

The market for wireless LANs has been growing significantly since 1990,
when worldwide sales were $3 million. The Yankee Group, a Boston-based
research firm, forecasts the worldwide market for wireless LANs to be $300
million by 1993.

RangeLAN features a range of up to 800 feet and high interference immunity
made possible by Proxim's patented spread spectrum technology. RangeLAN
operates at a data rate of 242 Kbps and provides users with three full
channels that effectively triple the available bandwidth, enabling users
to have three independent wireless LANs in the same physical space. By
using the spread spectrum technology, RangeLAN also features a highly
reliable signal reception that provides a consistent data rate over the
entire range.

"Because RangeLAN is designed to extend the LAN to both desktop and
portable systems' users can take advantage of a single wireless protocol
for all systems within their enterprise," said Smith. "We have leveraged
our experience in developing leading-edge spread spectrum products for
OEMs and have advanced the technology for the end user," said Smith.

RangeLAN will be sold through national and international distributors and
national retail outlets. Priced at $495 per unit, production quantities of
RangeLAN will be available through distributors in March. RangeLAN for
portable systems will be announced in Q2 1992.

Proxim Inc., headquartered in Mountain View, Calif, is the leading supplier
of spread spectrum communications products for OEMs and end users. The
company's family of wireless networking products allows Proxim customers
to achieve efficient, flexible connectivity while eliminating the expense
and difficulty of installing hardwired networks.
