If you have a CBRS 4G network to build, given requirements on facility characteristics, device density and application performance, Celona's Network Planner can help figure out how many indoor and outdoor access points (AP) you might need. But then again, all of us have to answer the simple question: what's the performance of a wireless AP?

Summary below highlights the expected total data rate for a CBRS based 4G AP, assuming several generic CBRS capable client devices are on the other end of the wireless connection. It is assumed that the AP comes with two radios, each capable of operating on a separate 20MHz channel within the CBRS spectrum. Note that Career Aggregation (CA) allows for bonding of 20MHz channels across two radios in the download direction and is not available for traffic flows in the upload direction.

Download speeds per AP with at least one client device active:

  • LTE-TDD Config 1 peak speed: 150Mbps with CA, 75Mbps without CA

  • LTE-TDD Config 2 peak speed: 200Mbps with CA, 100Mbps without CA

Upload speeds per AP with more than one client device active:

  • LTE-TDD Config 1 peak speed: 25Mbps per radio, 50Mbps per AP

  • LTE-TDD Config 2 peak speed: 12Mbps per radio, 24Mbps per AP
