Key Metrics for Successful WiFi Device Performance

Featured Product from Remcom (USA)

Wireless InSite®, Remcom’s site-specific radio propagation software for the analysis of wireless systems, features a Communication Systems Analyzer with important WiFi and LTE metrics for in situ assessment of devices such as smart home appliances and intelligent personal assistant devices, wireless access points (routers), LTE base stations, and more.

The Communication System Analyzer calculates bit error rate (BER) and throughput by post-processing Wireless InSite’s high fidelity signal coverage predictions, giving users the tools they need to visualize and optimize device performance.  Wireless InSite offers throughput options for WiMAX, LTE, and 802.11n and 802.11ac WiFi protocols.  A multi-stream parameter provides an estimate of potential multiple-input multiple-output (MIMO) performance.  User-defined throughput tables are also included, providing users with a mechanism for defining custom mappings between the signal quality and the modulation coding scheme and resultant throughput.

The Communication System Analyzer also includes Shannon capacity, a calculation of the upper bound on the data rate of a communication channel, and BER calculations to support modulation coding schemes up to 1024 QAM.  Metrics include signal-to-interference-plus-noise ratio (SINR), received signal strength indicator (RSSI), reference signal received power (RSRP), and reference signal received quality
