Must-Have Features to Look For in Your Next Wireless Test Receiver

As we’ve discussed previously cell phones alone can’t give adequate data for accurate signal testing. A dedicated receiver is the best choice for a variety of reasons, but what features should you look for when considering one?

Multiple Bands

The receiver should support all of the frequency bands and channels you require, or have the option to swap out modules for testing various signals. This eliminates the need to carry around multiple receivers. From legacy CDMA networks up to current 4G LTE modulation, the base receiver should support a host of RF bands and modulation schemes.

Simultaneous Testing

A receiver should allow you to run tests on multiple bands or channels simultaneously. This saves time and cuts down on the number of drive tests or surveys required to gather the information you need. It also lowers costs associated with labor, fuel costs and test vehicle maintenance.

GPS

A GPS module is essential for drive test studies, and also useful for outdoor stationary testing such as site surveys. Your next receiver should either have a GPS module built into the unit, or offer a connection port to interface with an external GPS.

High Measurement Rate

The minimum recommended sampling rate is 40 lambda, but a receiver with a higher sampling rate allows you to drive faster when conducting drive tests. This means you can get accurate test results in less time.

Captured Data Output

The ideal receiver should have the ability to capture data and store data without requiring a connection to a PC. This allows you to travel light without having to haul around a bulky laptop. It should also allow you to export the data via memory card or a direct connection to the computer. A direct connection allows you to transfer the information and import it into your software of choice. A memory card allows you to transport the data and examine it later without needing direct access to the receiver.

Removable and Rechargeable Batteries

Rechargeable batteries are cost effective, but they should also be removable. You don’t want a dead battery in the receiver to leave you dead in the water. A swappable battery allows you to keep several batteries charged in reserve for those long drive tests where there is no open 12v power supply.

Sensible Construction

One of the major problems with using regular cell phones for testing wireless signals is how fragile they are. Your ideal receiver should be built tough enough to withstand the bumps, knocks and drops that come with working out in the field. If the receiver has a screen, it should be large enough to read at a distance and easily readable under a wide variety of lighting conditions. It should also be compact and lightweight, so it doesn’t weigh you down while walking to the site.
