BlueKite Technology Becomes a Key Element of BT Cellnet's GPRS

Service; Wireless Browsing Speeds Increased by Up to Five Times

BlueKite.com, a leading wireless Internet software provider, has been chosen by BT Cellnet (NYSE:BTY) as a preferred supplier to optimize the transmission of web-based data over wireless. This formalizes a relationship that has included months of joint testing, development and trials. It also means that BlueKite technology will now be a core part of GPRS (General Packet Radio Service) services offered by BT Cellnet.

By incorporating BlueKite's Data Reduxion(TM) technology into its services, BT Cellnet will offer simpler, more advanced data applications for its customers. The technology enables wireless Internet and intranet speeds to be increased by an average of five times when compared with browsing not enabled by BlueKite's platform. It also reduces data transmitted by a factor of eight, thereby greatly improving bandwidth efficiency for both BT Cellnet and its customers. This means that customers will benefit from fast, seamless and convenient wireless web access at speeds equivalent to or better than fixed line connections.

Initially BT Cellnet's corporate customers are being offered BlueKite in the PocketNet Office portfolio of products and services, based on GPRS. To prepare for widespread consumer mobile web browsing services, BT Cellnet is also exploring possibilities for using BlueKite in other market sectors.

BT Cellnet has already identified the potential benefits that BlueKite optimization can deliver to large organizations. These include cost reductions due to reduced data volumes and increased customer satisfaction due to speed advancements.

In June 2000, BT Cellnet was the first mobile operator to roll out GPRS across the UK, and the operator is seen as the leader in terms of innovation and new service delivery.

Stuart Newstead, BT Cellnet's General Manager of Wireless Data, said, "BlueKite will allow our business customers to experience web browsing over GPRS in the same way they connect to their PC at their desk. The team at BlueKite supports our need to develop wireless business services, and this relationship will hopefully be extended to other markets."

Jan Wiejak, BlueKite's Managing Director for Europe, said, "We are delighted to be a supplier and to be associated with BT Cellnet, especially at a stage in the marketplace when Mobile Internet is becoming a reality for corporate users," Mr. Wiejak continued: "As strategic partners, BT Cellnet and BlueKite are demonstrating a commitment to work together to deliver superior GPRS and Mobile Internet solutions in a number of market sectors and countries. Furthermore, this venture will contribute to overall market growth by rapidly delivering easy-to-use, web-based applications to end-users. It is great news for us and for the industry."
