Scalable radio channel emulator for testing 4G LTE
EB Propsim F32 — with 32 RF channels and 128 fading channels –— is an easy solution for testing complex technologies such as 3G/4G, LTE, LTE-Advanced and beyond. It is a scalable test solution with up to eight times the traditional emulator testing capacity in a single box — hence being the first radio channel emulator that can truly test the performance of an entire 4G LTE network in a laboratory.
In order to ensure the reliable functionality of 4G LTE products, it is essential to accurately capture its veritable performance during R&D phase. EB Propsim radio channel emulators are designed to replicate wireless environments such as fading, noise and spatial channel conditions. The radio channel emulator isolates the performance issues of a developed product in all phases of R&D and therefore shortens the product development cycle, which provides cost savings down the wireless ecosystem.
"4G LTE creates design and test challenges with adoption of new technologies such as MIMO and beam forming. With this in mind, we have designed EB Propsim F32 to support our customers to conduct cost-effective LTE testing," said Janne Kolu, vice president, test tools at EB. "There is a remarkable gap between lab testing and field testing. Often the test results in the lab are good but the actual product performs badly in real field conditions. Our mission is to bridge this gap by bringing the most technically advanced test methods available to everyone working with LTE."
Further product features of the EB Propsim F32 include: high emulation capacity, scalable number of RF channels from eight to 32, setup-wizard and 24/7 automated testing for ease of use, and state of the art channel models and minimized test cabling.
