| Radio vendors for the private LTE network include Baicells and Ruckus, which is part of CommScope. Hunt Electric is deploying the radio network. Each school will get one outdoor Ruckus Q910 CBRS access point and one or two indoor Q710 APs, depending on the size of the building. Stewart said the goal is to blanket each building with coverage and to propagate the LTE signal in all directions outside the buildings. Students can connect from the schools’ parking lots or stadiums in order to access the districts’ content and communicate securely with teachers and other students. Stewart said the UETN network is very much a work in progress, and that his goal is to try various configurations and fail fast so that his team can learn what doesn’t work and what does work. One question is how far the radios will transmit in various environments. In some cases the Ruckus Q910 APs can broadcast up to 800 meters, but the range is usually less than that. He said Baicells CPE units act as extenders for the CBRS access points, increasing the network’s reach. However, he has told the schools in his district that the signal is not meant to provide LTE for the community-at-large, even though several smartphones now support CBRS.UETN is using generally available, unlicensed CBRS spectrum for its network. Stewart said his team considered bidding for priority access licenses (PALs) and decided it wasn’t necessary. “I just think there is going to be a secondary market,” Stewart said. “We are already talking to some of the PAL winners, and when you think about going inside our buildings, they really can’t go in there without us anyway. … I think they’re going to work with us.”Stewart said his interest in private wireless started more than two years ago. “We were looking for some sort of a solution that stayed wireless but gave you some of the benefits of having the fiber connection,” he said. He started learning about 5G, and realized that the next generation of cellular would require an exponential increase in the number of in-building radios needed. “I don’t want the carriers to get into that space and start charging me for every bit that I pass inside … all the 1,700 buildings that we connect,” he said. So Stewart started investigating private wireless, starting with Educational Broadband Service and soon pivoting to CBRS. So far, he likes what he sees. “I think there’s a lot of great things that will happen with this,” he said. Although Stewart doesn’t want to rely on the wireless carriers, he said he would love to partner with them to help enforce policies. He said the parents in his district have concerns about what their kids can see online, and he thinks the carriers could help enforce the private network’s content restrictions. “It would be great if whatever government building you were in, you had that ability to authenticate when you’re inside,” Stewart said. “We could do some things to make sure that if you were a K-12 student inside any one of those buildings, we’d make sure you were filtered and we’d have some control over that.” -- ???????? | |||
