Laying the Groundwork for WiMAX
Published 13th Apr 2009 | Source - Mobility | Pages - 4Thinking About Laying the Groundwork for WiMAX
Early trial results show wireless performance on par with T1 technology and expose early network integration considerations. AT&T is currently transitioning from a technical trial of early WiMAX access technology that involved a handful of customers and pre-standard equipment to one involving more than a dozen customers and standards-compliant equipment.
The primary goal of the first technical trial was to test the viability of the emerging wireless network as a potential access service by comparing it with T1 technology in terms of reliability and performance. The early trial indicated that WiMAX is on par with T1 technology in terms of the key network performance metrics: latency, jitter, throughput and packet loss (see Table on page 2).
Also, getting both carriers' and customers' feet wet with WiMAX has helped expose some integration issues with existing routing systems, primarily in the proper configuration for active/standby connection failover. Learning about these in a test scenario has educated participants so that they can be aware of how to best integrate WiMAX into their existing networks, should they decide eventually to go live with a commercial service.
