High-Powered 5G CBRS Operations Will Be Tested by Dish

5G

Dish Wireless has been given approval by the Federal Communications Commission to test CBRS outside power transmission limitations that are higher than those that are presently permitted. The testing will take place at the Table Mountain Radio Quiet Zone outside of Boulder, Colorado, close to NIST’s Colorado facility, as stated in Dish’s Special Temporary Authority filing. The technical study is being carried out with assistance from the National Institute of Standards and Technology (NIST) and its Institute for Telecommunication Sciences (ITS) lab.

Using Two Transmitters, Dish Will Test the 5G CBRS Band

Dish has argued in favour of higher-power operations in the CBRS band and is a significant holder of PAL licences. The business purchased 5,492 licences in 3,128 counties through the PAL auction for $912.9 million. In light of the fact that licences were offered in 3,233 U.S. counties, Dish exploited the auction to establish a national footprint for priority access to the 3.5 GHz CBRS spectrum.

Using five-generation (5G), two transmitters operating at 0.5 watts and up to 1.585 kilowatts of power will be used by Dish to test the CBRS spectrum at 3.65–3.69 GHz. The operator stated that it intends to carry out the experiments to assess the potential benefits of high-power CBRS operations in terms of coverage, throughput, and spectral efficiency, as well as the potential effects on current General Authorized Access (GAA) and Priority Access License (PAL) operations in terms of whether base stations or end-user devices may be interfered with. In its application, Dish stated that it also intends to examine the effects that waiving the in-band emission requirement of -25 dBm/MHz might have on GAA/PAL operations. This is done in order to synchronise with the adjacent C-Band.
