 CSL and Nokia have demonstrated what is claimed to be the industry's first seamless service continuity between HSDPA and EDGE networks. In practice, this means seamless hand-overs from HSDPA to EDGE and back without service interruptions.

With the Nokia HSDPA and EDGE solutions, CSL is confident it can offer its customers data services such as fast Internet access, rapid email and high-quality video streaming.

The demonstration took place as part o f a HSDPA testing within CSL's live network and using Nokia's HSDPA solution. The service continuity between the HSDPA and EDGE networks was demonstrated with large file downloads with commercially available HSDPA/EDGE devices; during the test download speeds of 1.6 Mb/s were steadily achieved in HSDPA.

After moving away from the HSDPA coverage area the service was seamlessly handed over to EDGE and continued at 200 Kb/s download speed. The same performance was also achieved when the download started in EDGE and upgraded to HSDPA as soon as the HSDPA coverage was available again. In addition to offering services to consumers using a multi-radio network, this system change allows CSL very flexible HSDPA roll-out possibilities.

 Nokia's HSDPA is a software upgrade to Nokia WCDMA networks, offering average data speeds of 1-2 Mb/s in the first phase. Later HSDPA supports up to 14.4 Mb/s according to the industry standard. The company has over 20 HSDPA contracts globally and 53 EDGE network references, suppl  yi  ng to over half the commercial WCDMA/EDGE operators. Nokia and CSL have been working together since 1991.

 \* CSL specialises in the mobile communications market in   Hong Kong  , launching its mobile services in 1983. It operates a GSM/WCDMA network through its mobile brands 1O1O and One2Free. CSL is 100% owned by Telstra.
