Transtema Deploys Aperto Networks for 3.5 GHz Municipal Broadband Wireless Access
In Kungsbacka, Sweden

Milpitas, Calif. and Gothenburg, Sweden. June 21, 2004 - Kungsbacka, one of the rapidly growing coastal municipalities in Sweden, has deployed Aperto Networks' 3.5 GHz systems for broadband wireless access (BWA) serving both rural and urban areas of the municipality. Five Aperto PacketWave^® base stations will provide complete BWA to the region.

The new Aperto-powered network complements the extensive fiber and radio infrastructure already in operation. "Aperto clearly stood out in the crowd as a feature-rich, robust and high performance system that fit our current and future needs serving the municipality, households and business users", says Ulf Lindälv, IT Director in Kungsbacka. "Our approach is to deploy an equal access network covering the entire municipality, allowing several competing providers to offer services to users in both urban and rural parts of the municipality. Aperto's unique technology allows us to meet our requirements in a cost-effective way".

Transtema, one of Sweden's preeminent systems integrators, has designed and deployed the network. It is using the municipality's newly-granted 3.5 GHz license and Aperto Networks' 802.16 class BWA systems. "We've worked with Kungsbacka since 1999, when we originally deployed the country's first LMDS system to provide high-speed connectivity for schools and other municipality needs," says Magnus Johansson, CEO Transtema. "We are proud to continue our co-operation with Kungsbacka and to deliver and operate the next generation BWA network.

"In particular," he continued, "the municipality will benefit from Aperto's VLAN double-tagging function, which allows us to configure multiple groups of users securely on the same network. We have numerous public and private consortia on the network, and in effect, we can segregate and securely tunnel their traffic with this feature. Together with the PacketWave Quality of Service (QoS) functions, we can achieve very high performance for many users and traffic types, at much lower cost than ever before."

Kungsbacka and Transtema are now preparing for the Aperto-powered network to be interconnected to a larger national network operated by the largest television and radio broadcaster and 3.5 GHz license holder in Sweden. The Aperto systems, already 802.16-class and carrier-grade, are well-suited to interoperability and have already proven their compatibility in hybrid, multi-vendor carrier networks in five continents, as well as their reliability in Aperto-centric networks in over 50 countries.
