2270/DM - Radio frequency Equipment

The Urban Flows Observatory at The University of Sheffield, led by the Departments of Civil and Structural and Automatic Control and Systems Engineering, is intending to undertake a survey of wireless networks using radio frequency technology. This will cover frequencies operated for Wi-Fi, Internet of Things (IoT) connectivity and cellular/mobile systems.

The purpose is to provide measurements of signal strength, signal-noise ratio and coverage to assess the likelihood of interference and problems that may be encountered as new systems are implemented to support the proliferation of low-power sensing that will form part of the IoT. Research is also planned that will inform how rapid changes to the urban landscape affect both regulated and unlicensed network systems and consider what steps could be taken to plan for transmission/reception issues.

The Observatory is looking to purchase three distinct systems and could be based on different product offerings, possibly from differing manufacturers or suppliers.

The systems required are:

1. Drive-test analyser 2. Walk-test analyser 3. Automated directional signal analyser (this could be combined with 1 in particular though the capability to use with 2 also would be seen as a benefit)
