Dish Wireless has received permission from the Federal Communications Commission to experiment with CBRS outdoor power transmission limits that go beyond those currently allowed.
According to Dish’s Special Temporary Authority filing, the technical study is being conducted with assistance from the National Institute of Standards and Technology (NIST) and its Institute for Telecommunication Sciences (ITS) lab; the testing will be conducted at the Table Mountain Radio Quiet Zone outside Boulder, Colorado, near NIST’s Colorado facility.
Dish will be testing CBRS spectrum at 3.65-3.69 GHz, using 5G with two transmitters at 0.5 watts and up to 1.585 kilowatts of power. The operator said that it wants to conduct the experiments to evaluate what the improvements to coverage, throughput and spectral efficiency would be with high-power CBRS operations, as well as what the impact would be to current General Authorized Access (GAA) and Priority Access License (PAL) operations in terms of whether base stations or end-user devices might be blocked under the higher-power conditions. Dish said in its filing that it also wants to test what the impact to GAA/PAL operations would be “if the in-band emission requirement of -25 dBm/MHz is waived to align with [the] adjacent C-Band.”
