Deploy and optimize CBRS wireless network
Citizen Broadcasting Radio Service (CBRS) is a 150 MHz broadcast band in the 3.5 GHz band. At the beginning of 2020, the Federal Communications Commission (FCC) approved the full commercial deployment of CBRS, paving the way for this year's 4G and private networks and the US's future mid-band 5G network. As new networks are established on this frequency band, RF engineers will need to conduct drive tests to evaluate network performance, determine coverage, and identify and solve problems.
Traditionally, drive test equipment is limited to specific frequency bands or technical standards, requiring users to purchase additional hardware or software to monitor multiple frequency bands. As CBRS-enabled spectrum sharing and increasing network complexity become a major challenge, wireless network operators need a solution to design and optimize networks, identify and locate destructive RF interference, analyze propagation characteristics and ensure this new standard Spectrum availability in
Application and requirements
RF engineers need a solution:
- Measure and analyze the new CBRS standard
- Record and store data for real-time analysis or post-processing
- Mobile and driving tests in the vehicle
- Easily upgrade to new technologies or new frequency bands
- Reduce network optimization and planning costs
The power of CBRS network
The CBRS solution is a fully integrated wireless network test system that allows RF engineers to use the same hardware for RF spectrum analysis and wireless technology scanning. This cost-effective, portable and universal solution enables engineers to simultaneously monitor and record the 3.5 GHz band of interest and the surrounding spectrum for accurate performance prediction or playback and post-processing.
Using Hongke ThinkRF TM real-time spectrum analyzer and leading CelPlan® software, the combined solution can be easily deployed in vehicles and provides all the analysis, scanning and storage functions required by users in one system.
The combined solution can:
- Basic planning and optimization
- Capacity planning for multi-technology networks
- Real-time collection of geotagged spectrum
- Network performance and coverage mapping
- RF interference search
- RF propagation characteristics
- Performance evaluation and benchmarking
