Scalable Network Technologies Unveils QualNet 3.6 Software; Latest Release Includes 802.11a, Satellite, and Cellular Network Models

Los Angeles--(BUSINESS WIRE)--April 11, 2003--Scalable Network Technologies (SNT), the developers of QualNet software, announced today that version 3.6 is now available for download. QualNet Developer 3.6 is the latest release of SNT's fast simulation software for communication networks. There are three significant additions to the model library:

• Cellular GSM
• Detailed Satellite
• IEEE 802.11a

"QualNet 3.6 is an important milestone for SNT," said Rajive Bagrodia, President and Founder of SNT. "Our customer base has been expanding rapidly, and these three new models represent some of the fastest growing areas in network modeling. Our detailed geosynchronous satellite model will be an extremely valuable addition to the ever-growing QualNet Library of Models. For Wi-Fi applications, our new IEEE 802.11a model will complement the 802.11b offering we've had for a while. And finally, the GSM cellular model is an important extension to QualNet. Our product is famous for the detail in which it models wireless communications, particularly in the physical layer. The new QualNet GSM cellular model should be unrivaled in speed and scalability."

In addition to nine new models added to the QualNet library, QualNet Developer 3.6 includes a number of functional improvements. QualNet Developer's code editor and assisted code development tools have been greatly enhanced, and threaded traffic file formats are now supported.
