Engineering Innovation Enables Cirronet to Deliver Enhanced

Residential Broadband Connections

Cirronet(TM) Inc., a broadband wireless Internet access equipment company that is breaking residential market deployment barriers, introduced today at SUPERCOMM 2001 the first last-mile broadband wireless product to take advantage of the Federal Communications Commission (FCC) regulation channel width changes in the 2.4 GHz band.

The FCC Part 15 regulation amendment, dated August 31, 2000, increased the accessible channel size from 1 MHz to 5 MHz for frequency hopping spread spectrum (FHSS) technologies in the license-free 2.4 GHz band. This amendment enabled Cirronet to apply value engineering to its broadband wireless equipment for enhanced near-line-of-sight (NLOS) connections and improved throughput speeds. Over wider channels, Cirronet increased the performance of its WaveBolt(TM) product family, designed to break deployment barriers in the residential and small business Internet access market, while maintaining a comparable price point. Cirronet's WaveBolt(TM) was the first last-mile Internet access product to technologically take advantage of the new regulations for FHSS systems.

"Our products are developed based on a solid understanding of market needs," said Robert Gemmell, CEO and chairman of the board of Cirronet. "Our customers have clearly told us that the market will not emerge until they have an affordable equipment solution, meaning a high-speed, near-line-of-sight solution that is cost-effective and can be user installed. The new FCC regulations will enable us to provide our domestic market with these features, as well as increased product scalability."

Cirronet has a long-standing history of meeting the needs of the market. WaveBolt was developed based on ISPs' requests for an affordable, robust and high-speed wireless access product priced under $400 per subscriber, including installation and amortized base station. Taking advantage of the FCC regulation changes is another industry first for Cirronet and an innovation that has enabled the company to deliver the most robust license-free wireless Internet access systems to the market.

Cirronet's proprietary, patent-pending media access controller (MAC) layer increases WaveBolt's robustness. It is engineered with flexibility to work with the wider hopping channels approved by the FCC. Cirronet, applying these regulation changes, will increase WaveBolt's bandwidth to 1.8MHz--balancing the higher throughput with improved receive sensitivity.

Cirronet uses FHSS technology as the foundation for its wireless data products. FHSS is a robust technology utilized in license-free frequency bands to overcome interference issues. Known for its excellent range, immunity to jamming and multipath fading, bandwidth, networking features and ease of use, FHSS allows the data to work around noise or interference. The network "hops" randomly and extremely quickly through channels. Transmission interference on one channel is eliminated within milliseconds with a `hop' onto the next channel. These features make the technology ideal for near-line-of-sight wireless Internet access in the residential and small business markets. Cirronet's WaveBolt remains both FCC and ETSI compliant and can be deployed internationally.

Cirronet(TM) is exhibiting its WaveBolt(TM) Internet access product family at SUPERCOMM 2001 at the Georgia World Congress Center in Atlanta, June 5-7. Cirronet can be found at booth No. 6790 in the Wireless Zone.

About WaveBolt

The WaveBolt product family is a point-to-multipoint fixed broadband wireless system designed to break the price and deployment barriers of the residential market. The WaveBolt subscriber unit--integrating a microwave antenna, radio and modem--is packaged as a small, hand-size device and is designed for easy mounting and connection, without opening a PC. Avoiding complicated in-home installations, the WaveBolt system uses the dial-up networking routines that are part of Microsoft Windows(R) to establish an always-on subscriber connection, eliminating the need for truck roll. Designed for adverse industrial conditions, the CPE maintains a near-line-of-sight (NLOS) connection with the ISP access point. Operating in the license-free 2.4 GHz band and approved by the FCC and ETSI, the system's patent-pending frequency hopping spread spectrum (FHSS) technology also provides immunity from potential jamming sources as well as security from eavesdropping. Cirronet's WaveBolt system delivers competitive market advantages through its proprietary media access controller (MAC), for which two patents have been filed.
