2.4 GHz systems generally offer a reliable signal and sufficient range for most RC applications. However, the effective range can be influenced by factors like obstacles and interference. Users typically enjoy good signal stability within the typical operating range of the RC car.
Unlike older radio systems that operated on different frequency bands and were susceptible to interference from other electronic devices, 2.4 GHz systems are less prone to interference. This is because they use a spread spectrum technology that can hop between different frequencies within the 2.4 GHz band.
This vid shows the effective range of low cost RC radio. As can be seen, the range is definitely long enough for day to day RC racing and bashing!
