NetTest releases QoS tester for wireless nets

NetTest has announced the release of QUEST GPRS, an IP (Internet protocol)-based protocol analyzer for wireless network operators.

NetTest says the QUEST GPRS is a device that works with off-the-shelf General Packet Radio Service (GPRS) mobile phones to facilitate end-to-end IP quality-of-service testing. The company says that together with software integrated in the mobile phone, the device gives GRPS operators the ability to gauge the performance customers receive when GPRS is deployed in their networks.

GPRS is a service that extends the current voice services of GSM (Global System for Mobile Communications) wireless networks. With GPRS, customers can send and receive packet-based data. GPRS is said to enable high-speed IP services without constant bandwidth consumption.

NetTest says operators can use QUEST GPRS to analyze user-level traffic to monitor for problems. Operators can distinguish between GPRS network problems and external IP network problems using this tool, NetTest says.

Other features include protocol analysis for each GPRS and GSM interface, and support for ATM interfaces.

QUEST GPRS also decodes over 250 IP protocols, including FTP and HTTP, the company said. It can be configured to work in portable and rack-mount configurations, and contains eight test interfaces in a single chassis.

Pricing starts at US$30,000.
