How will RF test cable change the future of road test

The launch of RF test cable will have a significant impact on real-time network test or road test. With the adoption of new technology and new strategy, new testing technology and equipment will be needed. Due to advanced transmission methods and the use of orthogonal frequency division multiplexing (OFDM) waveforms, RF test cable will greatly change the air interface. These new technologies will greatly improve the speed, network capacity and bandwidth efficiency, so as to greatly reduce the delay, less than one millisecond.

However, these huge improvements do bring challenges to test engineers, especially the road test will face considerable changes and challenges.
Although the implementation speed of RF test cable slowed down in 2020, the prospects for 2021 and beyond began to improve. According to the global system for mobile communications (GSMA), by 2025, 20% of cellular connections will be 5g, RF test cable. After 2021, RF test cable is developing rapidly, and network monitoring performance and coverage are crucial to commercial success.

Foundation of RF test cable
The key role of road test is to collect data about voice and data services of mobile network operators, and then measure it according to RF test cable. By performing such RF test cable tests, operators can prevent problems such as poor signal, low data rate, black spots in coverage, possible interference, video stream delay and dropping in an area. Operators solve any problem by ensuring high-quality service and high-quality experience, and minimize the loss of users.

How will 5g affect RF test cable
The implementation of 5g marks a big step towards a more intelligent society and also means great changes in the field of road testing. Although the basic knowledge remains unchanged, RF test cable has changed in the method of evaluating network coverage in specific areas.

Although the use of RF test cable will be a relatively small challenge in the 5g test field, the obstacles will be much greater when turning to complex multi antenna configuration and beamforming rather than traditional, evenly distributed cell-based coverage.

Firstly, whether in terms of energy consumption and cost, or in terms of the speed and reliability of RF test cable service, the multipath propagation of signals reaching the receiving antenna through multiple paths will improve the efficiency of mobile networks.

By using UAVs for aerial RF test cable and ground test, 3D maps of the coverage of each base station can be created, allowing the collection of vertical and horizontal data. This will provide clearer coverage and strengthen the decision-making process to make improvements.
