Japan wireless operator TU-KA group successfully launched high- speed wireless packet data services over its Motorola-supplied Personal Digital Cellular (PDC) system. TU-KA group subscribers in the Kanto region and in the major cities in the Tokai area now have the ability to wirelessly access the Internet at speeds up to 28.8 kilobits per second (Kbps).
TU-KA group customers will experience the benefits of 28.8 Kbps wireless Internet access using its mobile devices in Japan. The services were launched on Oct. 2. TU-KA plans to expand its high- speed data services in the major cities of the Kansai area in November 2001.
TU-KA was the first operator to implement Dynamic Equip Sharing (DES) software on its PDC network in 1997. DES software enables the network to respond to subscriber usage peaks by dynamically assigning base station resources to the busiest sector, thus meeting the changing traffic needs.
"TU-KA is ahead of the competition by a few months," said Hiroshi Fukumuro, managing director and general manager of the Technology and Engineering Division, TU-KA Cellular Tokyo, Inc. "We expect that this service will enable us to satisfy data service demand, which is growing rapidly, especially among young people in Japan, and our customers will be able to experience the benefits of high- speed wireless data transfer when they download various content, such as images and music files," said Fukumuro.
Motorola is a world leader in high-speed packet data wireless networks, having commercially deployed the largest number of IS- 95B packet data networks capable of data rates of 64Kbps and general packet radio service (GPRS) networks capable of data rates of 115 Kbps. Data services have also been deployed with Motorola's iDEN(R) technology.
"TU-KA accurately anticipated the need to increase data rates on PDC. We are proud to have provided a 28.8 Kbps high-speed wireless Internet access for a PDC system in Japan," said Shinji Ogura, general manager of Motorola's GTSS operations in Japan. "Motorola's move in high-speed packet data technology is another demonstration of the company's leadership and commitment to delivering advanced data solutions to our customers, and we will continue to provide our best technologies and services in order to assist customers in all their telecommunications needs," said Ogura.
Motorola's high-speed wireless Internet access was designed to allow sharing of network resources among a large number of data users who use applications that only require "bursty" intermittent connectivity. By maximizing efficient use of the resources, packet data services maximize the operator's revenue generation potential. This planned architecture minimizes the impact required to implement a packet data network into the existing radio network. The architecture lends itself well with how packet sessions are functionally isolated from voice calls even though they share physical resources.
