Oki Electric Unveils Distributed Access Points for Voice over Wireless LAN

Enabling Low Costs Wireless IP Phones with MWINS™ BR2100 Series

Tokyo, Japan, September 20, 2005 -- Oki Electric Industry Co., Ltd. (TSE: 6703) today announced Japan's first distributed wireless access points for Voice over Wireless LAN(VoWLAN) without the need of wireless LAN controllers. This new MWINS™ BR2100 Series that comes in two models, eliminates the costly LAN controllers and utilizes the existing network equipment, which enables users to establish a VoWLAN system at a low cost. Sales start today in the Japanese market with initial shipments due on November 21.

The use of the high performance Intel® IXP425 Network Processor in the MWINS BR2100 Series eliminates the need for costly wireless controllers and switches of the conventional systems. Additionally, the MWINS BR2100 Series enables nearby access points to exchange information, such that high-speed network is no longer necessary to avoid latency between wireless LAN controllers/switches and access points. The new "MWINS BR2100 Series" includes two models:

MWINS BR2101" that allows switching between IEEE802.11a or and 11b/g and is suitable for customers with relatively small data traffic.
MWINS BR2102" that allows simultaneous use of IEEE802.11a and 11b/g and is suitable for customers with large data traffic.

"Our MWINS BR2100 Series is Japan's first distributed access point, enabling users to easily establish a VoWLAN system,"said Masashi Tsuboi, President of IP Systems Company at Oki Electric."To establish a best-suited VoWLAN, high-skilled technology is necessary to analyze design and manage wireless environment. Based on the strong track record Oki has established through SS9100 mobile IP systems, Oki will provide a one-stop VoWLAN solution that includes design, establishment, operation, and maintenance services."

"The performance and flexibility of our network processor technology has become very attractive in communications systems, including WLAN access and VoIP related applications,"said Ton Steenman, General Manager of Intel Infrastructure Processor Division."In addition to best in class performance, and a rich feature set, Intel's network processors offer customers the flexibility to optimize designs for target specifications."

Oki included several functions to maintain high voice quality in VoWLAN system such as:

Quality of Service (QoS) control function to prioritize voice packets (in compliance with IEEE802.11e; the Enhanced Distributed Channel Access -EDCA- method).
Connection limiting function to prevent voice degradation caused by wireless traffic overflow during terminal concentration/
High-speed handover function to control call drops while in transit.
Security and encryption function (in compliance with IEEE802.11i) to avoid eavesdropping, falsification and identity theft.
