***Iospan Wireless Completes Field Trials of First MIMO-OFDM Non-
Line-of-Sight Fixed Broadband Wireless System
(January 14)

Iospan Wireless, Inc., a provider of wireless broadband multiple
antenna technology, today announced the first successful field
demonstration of a Non-Line-of-Sight (Non-LOS) fixed wireless
network utilizing Multiple Input, Multiple Output – Orthogonal
Frequency Division Multiplexing (MIMO-OFDM) technology. This
wireless technology is the first, and currently only, one to meet
all six of the IEEE's standardized channel models for Non-LOS.

Iospan's field trials used their MIMO-OFDM-enabled AirBurst™
technology to deliver symmetric multi-megabit data rates between
a 50-foot cellular base station antenna and a dictionary-sized,
indoor home CPE located nearly four miles away in a stucco-walled
apartment (representing the home of a user). Statistics from the
trials announced today include peak individual downlink rates of
over 13.6Mbps using Iospan's 2MHz channelization, which equates
to over 40Mbps on a typical 6MHz MMDS channel. Iospan believes
that with a base station antenna of 100 feet, as opposed to the
50 feet, AirBurst technology could deliver these speeds at
distances of up to 10 miles.

The trials of AirBurst™ technology are being conducted in the San
Francisco Bay Area using the 2.5 – 2.686 GHz Multichannel
Multipoint Distribution Service (MMDS) frequency band. The
demonstrations also included several streaming videos running
simultaneously to standard laptop computers utilizing an 802.11b
wireless local area network.

Iospan offers AirBurst reference designs, chipsets and board-
level solutions to wireless OEMs interested in creating broadband
wireless systems designed for the residential and small to
medium-sized business markets.

Iospan Wireless plans to continue field trials of its MIMO-
enabled AirBurst technology through early 2002. They have already
announced plans to begin international field trials of AirBurst
with International Networks Company (INC), a subsidiary of Emaar
Properties, a large technology company in the Middle East. In a
letter of intent recently signed by the two companies, INC has
stated that it plans commercial deployment of systems based on
Iospan's AirBurst technology in the broader regional markets
following successful field trials in 2002 and local regulatory
clearances.
