HomeRF Working Group Announces First SWAP Wireless
Home Networking Products to Debut

Group Approves Specification Updates to Speed Adoption, Proxim and Motorola Announce Plans to Ship End-User Products

SAN FRANCISCO, June 7, 1999 - In the ongoing effort to make wireless home networking standards a reality, the HomeRF Working Group (HomeRF WG) today announced that several companies are developing end-user products based on the Shared Wireless Access Protocol (SWAP) which are expected for release to the market by this winter. In support of this effort, Proxim, Inc. (NASDAQ: PROX) has today announced that its Symphony Cordless Networking Suite will become SWAP compliant and will be fully backward compatible with currently shipping Symphony products.

The HomeRF WG also today announced the release of SWAP 1.1, which incorporates several low-level changes to the SWAP specification. Launched in January, the SWAP specification provides an open platform that enables a broad range of interoperable consumer devices for wireless voice and data communications in the home.

"The broad industry support that the HomeRF Group has garnered has allowed us to rapidly move the SWAP specification to the point where these companies can begin delivering end-user products," said Ben Manny of Intel Corporation, chairman of the HomeRF WG. "We envision that these first products are simply the initial step in enabling the flexibility and mobility that consumers expect, and demand, for delivering Internet access and next generation cordless telephony service anywhere in the home or yard."

Products Coming From Industry Leaders Proxim has announced that it will add SWAP 1.1 support into new members of its Symphony product family. This will include a cordless USB adapter for desktop computers, a cordless PC card for notebook computers, and a cordless miniature design-in module for radio integration into products such as broadband Internet gateways. These new SWAP compliant devices will ship with Harmony? bridging software to enable seamless interoperability with currently shipping Symphony and other OpenAir? wireless LAN standard-based enterprise wireless LAN devices.

Earlier this year, Intel Corporation (NASDAQ: INTC) and Proxim announced a technology relationship to develop wireless home networking products also based on the SWAP specification. Last week, Motorola, Inc. (NYSE: MOT) and Proxim announced a partnership to produce integrated wireless networking products for shared high-speed Internet access in the home or small office based on SWAP.

SWAP 1.1 Release In a continuing effort to drive the market adoption of wireless home networking, the SWAP 1.1 specification update enables lower cost radio implementations and assists group members in meeting year-end product availability goals. Several low-level technical changes were made that allow companies to take advantage of existing technologies, enabling the rapid development and delivery of SWAP-based end-user products, including those announced today by Proxim, and by Motorola and Proxim last week. This update signifies the collective commitment of the group's 90+ members to ensure the broadest, quickest possible implementation of wireless home networking.

Through SWAP, consumer electronics and small appliances in and around the home will contain wireless technology that will enable them to "talk" to each other and share the resources of the connected PC without being tethered to the existing wiring and wall outlets in the home. For example, a mobile display pad linked to the Internet could access recipe information in the kitchen, be taken into the yard to assist with plant and disease identification in the garden, or be used in the garage by the automotive do-it-yourselfer looking for the latest shop manual updates.

Broad Market Support Market leaders lend their support for the SWAP specification and the wireless networking market- "We are proud to make the vision of the Home RF Working Group a reality and be the first company to announce the availability of products complying to the SWAP specification. The enormous backing of this industry group and its work toward an open cordless networking standard for the home further validates what we've believed for years - that users want the flexibility of a cordless solution to compute and be connected to information from anywhere they feel most comfortable." --Brian Button, vice president, Sales and Marketing, Proxim

"HomeRF's robustness and integrated voice support make it particularly attractive to consumers. The technology will let consumers enjoy effortless and simultaneous access to the Internet, Telephone services, and their Home Computer Network" --Vedat Eyuboglu vice president and general manager for Motorola's Broadband Home Networking Products

"The approval of the SWAP 1.1 specification and Intel's technology relationship with Proxim will enable the delivery of cost-effective wireless home networking solutions. Wireless technologies based on HomeRF SWAP will compliment Intel's line of phoneline networking products and extend home networking to mobile devices in and around the home." --Dan Sweeney, general manager of Intel's Home Networking Operation.

"HomeRF is an important initiative to making the pervasive computing vision a reality for consumers. We will be extending our product lines - Aptiva, Home Director, and ThinkPad - to take advantage of wireless networking. I believe that wireless connectivity adds an essential element to both wired and unwired homes that are technology ready for today and tomorrow." --Mary Walker, general manager, IBM Home Networking

About The HomeRF Working Group and SWAP
Launched in March 1998, The Home Radio Frequency Working Group has developed a single specification (the Shared Wireless Access Protocol - SWAP) for a broad range of interoperable consumer devices. SWAP is an open industry specification that allows PCs, peripherals, cordless telephones and other consumer electronic devices to share and communicate voice and data in and around the home without the complication and expense associated with running new wires. SWAP-compliant products operate in the license-free 2.4 GHz frequency band and utilize frequency hopping spread spectrum RF technology for secure and robust wireless communications. The current membership of the group exceeds 90 companies and is made up of leading companies across the PC, consumer electronics, networking, peripherals, communications, software, retail channel, home control and semiconductor industries worldwide.
