In real deployments, your receiver must decode a wanted signal while strong unwanted signals are present nearby in frequency. Receiver blocking evaluates that resilience. What Receiver Blocking Actually Means Receiver blocking is the receiver’s ability to keep working when two RF signals are present: A wanted signal: the one your device should decode A blocking signal: an unwanted interferer that is intentionally made strong During a blocking test, the wanted signal is usually set near the receiver threshold, while the blocking signal is applied at specific offset frequencies defined by the applicable standard.
