How much range does 2.4G Tx/Rx give? (2024)

FAQs

What is the range of a 2.4GHz remote control? ›

2.4GHZ transmission: Anti-interference, remote control distance can reach 500 meters.

Radio control

Many radio-controlled drones, model aircraft, model boats and toys use the 2.4 GHz band. These radio systems can go up to 500 meters in R/C cars and over 2.5 kilometres (1.6 mi) in drones/airplanes.

Generally, modern RC transmitters offer a reliable control range of several hundred meters to several kilometers. Transmitters operating in the 2.4GHz frequency band, which is commonly used in RC systems, can typically provide a range of several hundred meters.

RC control range varies greatly depending on system used, installation, antennas used, terrain, and even weather conditions. But in general, for discussion purposes here, RC systems can be categorized into Short Range (2km and under) , Medium (2-10km) and Long Range (>10km).

Use 2.4 GHz for a device farther from the router

This wavelength has a longer range and can penetrate solid objects more easily than the 5 GHz band, making it ideal for devices that are taken from room to room or are further away from the router.

The 2.4 GHz WiFi frequency has a longer range but a lower bandwidth. This means it has a long-range coverage area, but it comes at a cost, which is slow speed. However, this does not imply that the frequency's slow speed renders it useless.

Advantages and Disadvantages

2.4 GHZ. Advantages: farther range, can penetrate through solid objects easier. Disadvantages: because 2.4 GHz is more common, it's more susceptible to interference, slower speed.

The primary differences between wireless frequencies are the range (coverage) and bandwidth (speed) that the bands provide. The 2.4 GHz band provides the most coverage but transmits data at slower speeds. The 5 GHz band provides less coverage but transmits data at faster speeds.

Convenience. The 2.4 ghz band RC systems are the most common. They are now insignificantly more expensive to manufacture than the older AM and FM systems and they provide better reliability.

With 2.4GHz effectively 40 channels are available and the sets automatically set themselves to an unused frequency when switched on. Operation is constantly self monitored and the set will move to an unused frequency if any interference is detected.

Is 2.4GHz good for RC? ›

In general 2.4 which normally is frequency hopping and is reliable so long as you're not near any interference which can come from a cell tower and your setup installation is done correctly. Good antenna placement and reliable power source to receiver.

Being low-powered, most transmitters typically have a short range of 100–300 feet (30–91 metres), depending on the quality of the receiver, obstructions and elevation.

The radio technology of RC cars these days uses the 2.4 GHz frequency, which makes it possible to drive dozens of cars simultaneously without having to manually change the frequencies. After the transmitter and the car's receiver are bound, their functioning won't be interfered by other radio equipment.

90% of the time you will be working within the range of 5 to 30 meters (15 to 100 feet) because the limitation will not be the radio signal, but your eyesight.

Range and Penetration

2.4GHz: Better at covering larger areas and penetrating through walls and floors. 5GHz: Provides stronger performance in smaller spaces with less physical obstructions.
