5G & Cellular Coverage

5G makes this harder in two ways. First, the spectrum is wide and fragmented, from sub-1 GHz low band through mid-band and on into the millimeter-wave frequencies above 24 GHz. A receiver that stops at a few gigahertz does not reach the FR2 bands that carry the most capacity. Second, mmWave signals are fragile. They fade fast, bounce off glass, and drop behind a wall or a parked truck. Coverage that looks fine on a planning map can collapse over a few meters of real street. That behavior is characterized on foot and by vehicle, point by point, across the bands in service.

How the ICX-FieldHawk line solves it

The ICX-FieldHawk platform brings frequency reach and field portability into one instrument. Coverage extends to 40 GHz on the ICX-400, which puts the FR2 bands n257, n258, n260 and n261 in range alongside low-band and mid-band cellular; n259 runs to 43.5 GHz and is covered in part. One analyzer covers the survey instead of forcing a team to carry a separate box for the high band.

The SpectraCore software drives the measurements that coverage work depends on, and both are standard on every model. Channel power gives a calibrated read of how strong each carrier arrives at the test point. ACPR, the adjacent channel power ratio, shows how cleanly a transmitter stays inside its assigned channel and how much energy spills into its neighbors. Together these answer the two core questions of any coverage survey: is the signal strong enough here, and is it clean enough to coexist with the channels around it.

The workflow is built for movement. In a walk test, an operator carries the analyzer through a building, a venue, or a campus and records measurements along the route. In a drive test, the same instrument rides in a vehicle and logs the same metrics across miles of road. On the ICX-045, 060 and 090, Mapping mode is standard and stamps each reading to its GNSS position on a heat map. On the 9.5, 20 and 40 GHz models the survey software matches each reading to its own GNSS log by timestamp, with the analyzer’s 1PPS synchronized to ±100 ns. Either way the result is a picture of how coverage rises and falls across the area served, rather than a single number.

Which models and accessories fit

For walk tests and indoor surveys, the ICX-FieldHawk handheld is the practical choice: a 1.5 kg instrument with a 10.1-inch display and about 3 hours of battery (2.5 hours on the ICX-045/060/090), so an engineer can sweep a floor, a stadium concourse, or an office tower without a laptop. The result is faster routes and fewer things to break.

For drive tests and vehicle-mounted survey rigs, the ICX-Series USB analyzer (ICX-200U to 20 GHz, ICX-400U to 40 GHz) integrates cleanly into a logging setup. It draws 10 to 14 W over its Type-C connection and streams measurements to the survey software running on the test computer, which makes it a good fit for permanent or semi-permanent vehicle installations.

For survey teams that work outdoors in heat, dust, and rain, the ICX-FieldHawk-R variant carries the same measurement capability in an IP68 impact-protected chassis with temperature classes to -40 °C. When direction toward a specific cell or interferer matters, the RFA-3100-N directional antenna adds a directional front end from 500 MHz to 10 GHz with a 20 dB amplifier that can be bypassed, useful for isolating one carrier from a crowded skyline.
