| In CBRS lingo, CBSDs refer to Citizens Broadband radio Service Devices, which may include access points or small cells. During the March to April time frame, across the industry, the CBRS ecosystem consisted of 17 CBSD vendors, 48 different FCC-certified CBSD models, 70 different FCC-certified end user devices and modules, and more than 1,250 Certified Professional Installers (CPIs). Google`s Spectrum Access System (SAS) supported all of the hardware and Google helped train a large fraction of the CPIs.“We take mobility for granted, but hand-overs are a hard problem and LTE is a proven solution,” Marshall told FierceWireless via email. “We see demand in places where robots and autonomous vehicles need to move around, like in warehouses, distribution centers, or agricultural fields. Those devices need to maintain connectivity at all times.”Examples where Google sees demand are applications in factory settings where even small amounts of downtime can be very costly and where safety is a factor. For example, a factory might need to immediately turn off a robot in a hazardous situation. Or, a job like remote video monitoring might be done more effectively with LTE.CBRS also covers a wider area with fewer radios than a Wi-Fi system. If a business needs to cover a distribution center spanning many football fields or acres of farmland, CBRS will do the job. And in terms of control and security, CBRS lets enterprises take control and put radios where they’re needed without having to depend on a third party.According to Marshall, for many enterprises, it may not make sense to bid on a county-wide license, and the GAA will suffice. Where PALs get more interesting for enterprises is sub-leasing, where a company might want a higher guarantee of spectrum availability for the long term, but only needs it for a small geographical footprint. -- ???????? | |||
