Chevron Nigeria uses new USA produced WiFi-Plus multi-polarity obstruction penetrating antenna for successful telecom in challenging environment

Chicago, IL July 18, 2004 -- New, patented antennas from WiFi-Plus, Inc. which are being used in city-wide WiFi deployment in Lancaster, CA and electronic signage networks on the streets of New York City, is connecting Chevron in Nigeria to the world through an 802.11b hotspot.

"The vastly superior performance of the WiFi-Plus antenna, and the associated need for less equipment overall, allowed us to proceed with this project, and to enjoy very high telecom performance" said Jaime Vargas Communication Consultant for Why Wire, Inc. the project spokesman.

Mr. Vargas of Why Wire added, "By integrating WiFi-Plus, Inc. obstruction penetrating antennas with our Rasta 2400 base stations, we were capable of delivering reliable, available, scalable wireless telecom which as an added bonus, required only a quarter of the base stations originally expected. All other antennas tested either failed or rendered the project cost-prohibitive. WiFi-Plus is clearly the new standard. Finally for the customer premise (CPE) we decided to use the Horizon cards by Direct2Data. These cards not only out performed other card, but they we are able to provide a good data throughput even on a fair or faint signal level".

The patented WiFi-Plus, Inc. multi-polarity antenna met the challenges of a particularly difficult wireless telecom environment. Signal obstacles in the 3 mile radius included:

1. Buildings made of concrete walls or center block walls with reinforced steel.
2. Building exterior was 100% covered with highly reflective tile with few windows (windows allow the signal to propagate inside).
3. Dense foliage
4. Roofs made of aluminum.
5. Humidity reaching 90%, temperatures as high as 110F, and monsoon rains.

While speaking with leaders from the satellite, military and homeland security sectors as well as municipal and telecom industry representatives during ISCe2004, the International Satellite Conference and Expo, held in Long Beach, CA, WiFi-Plus, Inc. President Dennis Broderick said, "The flow of commercial and public safety information between people and devices is no longer impeded by performance or cost constraints that have been imposed by antenna technology. WiFi-Plus multi-polarity antenna technology created in the US enables the next generation of connectivity to proceed."
