Long Range: Over 1Km distance via BLE
In previous timings, radio transmit power played a crucial role in increasing the range of BLE products. With the introduction of Bluetooth modules based on Nordic solutions, users are able to obtain better communication protocols. This module supports BLE 4.2/5 protocol. Bluetooth version 5 provides long-range mode. The design of this long-range wireless module provides considerable power efficiency while achieving a coverage range of over 1Km.
In these devices, Wi-Fi and Bluetooth communicate through serial ports for transparent data transfer. The long-range module helps extend the range of the Bluetooth connection to experience enhanced positioning; it also enables robust communication in areas modbus tcp gateway
where users encounter obstacles with previous wireless devices. In addition, Long Range also supports transparent signaling.
Achieving a range of more than 1 Km via BLE depends on the surrounding environment, antenna and radio signal performance. Therefore, there are many factors that can affect the working of Bluetooth range. Typically, they are:
`Antenna
a Physical obstacles in the data transmission path
b Receiver sensitivity
cTransmitter output power
BLE technology itself has limitations based on the use of modulation. Since the performance of the antenna and radio remains fairly static for a particular Bluetooth device, the surrounding environment varies widely. For example: people may get a range of up to 100 meters outdoors, which is a rare situation. In indoor Bluetooth positioning and navigation, obstacles such as concrete walls can reduce the strength of the radio signal. Therefore, the effective range is significantly reduced.
When creating a Bluetooth device, a manufacturer can choose to give it a better range. They can also move on by choosing the Bluetooth chip with the best receiver sensitivity. In addition, its output power should ensure that the device has a good antenna. But in some cases, users need to transmit data over hundreds and thousands of meters via Bluetooth technology. In this case, they use a different network to achieve a higher range of the bluetooth module.
