Mobile Backhaul Transition Requires New Testing
|
|

Ethernet technology requires careful attention to match these capabilities. Testing for Ethernet-based mobile backhaul systems can be split neatly into performance testing and conformance testing. It is essential that wired and wireless components now be tested with the same types and scale of traffic seen in actual network deployments.
