GPRS tests fail to impress 06:28 Saturday 26th May 2001 David Neal, IT Week Data transfer rates of 30 kbit/s are just a pipe dream for now Tests on the performance of existing General Packet Radio Service (GPRS) services have found that the much-vaunted data transfer rates of 30kbit/s are as yet unproved, and may be some time in coming. Earlier this month BT Cellnet began offering GPRS network access to mobile phone users. BT said that by using three time slots it could give users a peak data rate of up to 30kbit/s three times that of the 9.6kbit/s offered by GSM networks. However, recent figures suggest that GPRS is under-performing. Anite Telecoms has been monitoring GPRS from a user's perspective with its wireless data performance tool, WAM, which the company launched earlier this month. It has so far only recorded data transfer rates of 8kbit/s much lower than predicted. Anite's business manager for WAM, Warren Saunders, said he was surprised to see that data transfer rates were lower than those predicted by companies offering the service. "We were amazed that the wireless data revolution, like WAP before it, is less than impressive," he said. Saunders indicated that data transfer rates may be low because the service is in its infancy, and because of the nature of the system it uses. He said the fact that it is packet- rather than circuit-based meant there was a "negotiation going on" that governed the sharing of available bandwidth. This negotiation "would take some time to address". Saunders said that until the problems were ironed out, operators should charge users on a quality of service basis. "A bill that says you used that much data last month means nothing to most users," he said. "I would rather pay for the services I use. More for voice, less for email and even less for Web content." WAM costs £15,000 for a single-user licence. It comes installed on a laptop with a GSM or GPRS cardphone preinstalled. Businesses can use it to monitor the service that their users receive when accessing their content in a wireless environment. news.zdnet.co.uk
