Abstract: A multichannel radio receiver configured for real-time radio channel assessment is described herein. In one example, a radio frequency (RF) front end provides a frequency spectrum which is converted into a digitized spectrum. Within a digital subsystem, resources (e.g., software or a hardware device) may analyze channels or portions of spectrum within the digitized spectrum for a packet error rate (PER) at a plurality of power levels and a plurality of modulation schemes. The analysis may result a required received signal strength indicator (RSSI) that is needed to result in a particular read reliability requirement (RRR). Using the required RSSI, endpoints communicating with the multichannel radio may be associated with a channel(s), modulation scheme(s) and/or power level(s) that results in the RRR. The analysis may be performed by one or more resources operating in parallel and operating in the background to other communications between the endpoints and multichannel radio receiver.
