Wi-Fi HaLow Radio Technology 6
The following image is a simplified visual to illustrate how Wi-Fi HaLow technology compares with
standard Wi-Fi, and Trimble Long Range Radio.
Wi-Fi HaLow compared to Standard Wi-Fi
Both Wi-Fi HaLow and standard Wi-Fi radios are based on the IEEE 802.11 standard and operate in
license-free ISM frequency bands. The frequency of operation for Trimble SX12 standard Wi-Fi
radio is within 2.4 GHz band whereas Wi-Fi HaLow radio uses sub-1GHz frequency band.
In the field, Wi-Fi HaLow provides a more robust radio link at a further range compared to standard
Wi-Fi based on the following two factors:
1. 900 MHz radio waves (Wi-Fi HaLow) have longer range and better penetration through
objects because they don't reflect off of dense objects as much as 2.4 GHz radio waves
(standard Wi-Fi).
2. In populated areas, the standard Wi-Fi spectrum is often congested by consumer devices
such as home Wi-Fi networks and Bluetooth devices.
Wi-Fi HaLow vs. Long Range Radio (LRR)
Trimble Long Range Radio is a proprietary radio that operates in 2.4 GHz ISM band while using
Frequency Hopping Spread Spectrum (FHSS) technology for communication. As a result, it can
achieve a longer range than standard Wi-Fi radios.
In absence of external sources of interference, both Wi-Fi HaLow Radio and Long Range Radio can
be expected to significantly surpass the connection range of standard Wi-Fi.
