CBRS Offers 'Bandwidth Abundance,' Will Spur Innovation, Says Google

The citizens broadband radio service offers “bandwidth abundance,” said Preston Marshall, principal wireless architect for Google Wireless, during an Enterprise Wireless Alliance virtual conference Thursday. He's surprised about how fast the band's use has grown despite the pandemic and the amount of interest in private LTE. “It was developed, supported by the cellular industry,” he said: “It’s available to you” and you can buy equipment off the shelf. You can deploy “very rapidly” without “having to develop your own unique, proprietary hardware,” he said. Marshall predicted CBRS will be widely used by startups. “You can start small and you can grow,” he said. The cost of spectrum has “been an obstacle” because it was expensive, he said. Obstacles remain, he said. “We still need to work on how we create seamless roaming and authentication between operators,” he said. “The business models are still evolving -- who pays for what, how much do they pay, what are the methods of managing these transactions," he said. Further work remains on coexistence in a shared band, he said. Equipment makers also need to include the band in more handsets, he said. Mark Gibson, Commscope senior director-business development and spectrum policy, said the biggest surprise was the $4.6 billion raised in the CBRS auction, with more bidders than any previous FCC auctions. Big players like Verizon and Dish Network dominated the auction (see 2009020057), but the cheapest licenses went for as little as $1,100, he noted. It’s “the people’s band” with wireless ISPs and electric utilities bidding in their first spectrum auction, he said.
