Wi-FiHaLowRadioTechnology 2
Introduction
The Trimble® SX12 scanning total station comes in two different models: one with Long Range
Radio, and a new version with Wi-Fi HaLow™ radio technology. Each model also includes standard
2.4 GHz Wi-Fi™ as a secondary communication method.
Traditionally, wireless communication methods are a tradeoff between range and how much data
can be sent and how quickly (throughput). The Long Range Radio model of the SX12 can achieve
impressive range, but is limited in throughput. Conversely, when using standard 2.4 GHz WiFi on
the SX12, the throughput allows you to easily transfer scans or panoramas, though the range is
limited.
The new SX12 with Wi-Fi HaLow model provides the best of both technologies -- you can perform all
of the high-throughput functions you require, the connection is extremely robust, and you can
work at the range that you want with a robotic total station, all without having to switch or think
about communication methods.
This white paper describes Wi-Fi HaLow technology, how it compares to other radio technologies,
and how it works with a Trimble SX12 scanning total station and a Trimble controller equipped with
an EM130 module.
Note - Due to government regulation of communication frequencies, the Trimble SX12 with Wi-Fi
HaLow model and EM130 are only available in the United States of America, Canada, Australia
and New Zealand.
