What is an RF Drive/Walk Test?
When mobile networks are built, testing is required to ensure they function properly. However, time can take its toll on the network’s performance. Issues such as dropped calls, slow speeds, security breaches, and more can occur as networks age without proper maintenance.
To make sure this doesn’t happen, telecommunications engineers and technicians use drive and walk testing to find where potential issues may be interrupting a network signal.
RF Drive/Walk Testing Explained
RF drive/walk tests are a subset of “speed tests,” which test a phone or mobile device’s download and upload speeds, along with other factors that may affect performance.
RF drive/walk testing helps maintain a mobile radio network’s quality of service (QoS). It measures and analyzes the coverage and capacity of a network, providing wireless carriers with the data necessary to adjust to any network. RF drive/walk testing supports multiple areas of network performance, including:

RF drive/walk testing supports multiple areas of network performance, including:
- Public Safety
- LTE
- UMTS/WCDMA bands
- ITCR positive train control systems
- 2G, 3G, & 5G
- Safety standards, such as P25
RF Drive Test
RF drive testing is performed while a vehicle is in motion. To improve accuracy, RF drive tests evaluate network quality during peak usage to ensure the speed of the network remains reliable under heavy traffic. Additionally, RF drive testing ensures signals can handle speeds ranging from 20 to 60mph, and sometimes higher.
RF drive test engineers can analyze GPS data, interference, and signal levels while detecting call inconsistencies, including dropped and blocked calls.

RF Walk Test
While RF drive tests collect data from outdoor locations such as streets and highways, RF walk tests are performed in pedestrian settings. In other words, tests are conducted indoors and in urban areas to check for coverage in high-density environments, while also identifying any potential dead zones. As a result, these tests are also conducted either stationary or at a slow-walking pace to provide an added layer of data compared to RF drive testing.
RF Drive/Walk Testing Standards
The Federal Communications Commission (FCC) does not oversee or regulate all speed tests, but they have measures such as the FCC DA 18-710 to make sure internet service providers (ISPs) test their speeds to meet acceptable compliance requirements. Additionally, they provide an avenue for consumers to view their mobile connection and, if necessary, report inadequate speeds in their area through the FCC mobile speed test app.
While the FCC is the leading regulator for speed tests in the US, there are other organizations that have authority on speed testing overseas. A few examples of these regulating bodies include: The UK’s the Office of Communication (Ofcom), Australia's Australian Communications and Media Authority (ACMA), and India’s Telecom Regulatory Authority of India (TRAI).

RF Drive/Walk Tester Applications
RF drive/walk tools record a variety of mobile cellular parameters, using RF and signal processing. Network coverage, QoS, and capacity can be determined using an RF drive/walk tester, a user-friendly device with multiple network testing capabilities. The testing method depends on the area and the testing requirements of the network. Common applications for RF drive/walk testers include:
- Signal quality testing
- Public Safety, LTE, and UMTS/WCDMA band support
- Data that can be used to enforce standards for new or existing buildings
- Automated & simultaneous testing capabilities
- GPS tagging and the ability to save traces
- RF and signal processing path with impressive bandwidths
- Troubleshooting & monitoring tests
- User-definable input frequency ranges
- User-friendly interfaces
- P25 drive capabilities
- P25 walk test capabilities
