Overview
Ballast Networks built a CBRS (Citizens Broadband Radio Service) network at The Sound Hotel Seattle Belltown, a hotel of about 140 rooms in downtown Seattle, using Airspan Networks radios and a Druid Software core; it covers roughly 10,000 square feet across the first two floors from four transmission sites.[1][2] Comcast Business announced the hotel as a customer on November 29, 2022, saying it and Ballast used General Authorized Access (GAA) spectrum and Comcast's Priority Access Licenses (PALs), with a multi-operator core network (MOCN) gateway so the same system could act as a neutral host for mobile carriers.[3] In July 2023 a Ballast co-founder told Light Reading the network was carrying commercial traffic for AT&T customers, with 911 routing working, and that Ballast had paid the roughly $40,000 installation cost so it could use the hotel as a product showcase.[2]

- Technology
- A private cellular network linked to AT&T's public network through MOCN.[1] The hotel's general manager called it a 5G private wireless network in Comcast's release;[3] the radio generation is not otherwise detailed.
- Scale as reported
- About 10,000 square feet on the hotel's first two floors, served from four transmission sites.[1][2]
- Vendors and roles
- Ballast Networks: implemented the end-to-end network.[1] Airspan Networks: radios. Druid Software: core.[1][2] Comcast Business: service provider and PAL spectrum.[3] AT&T: network technicians supported the MOCN build and testing.[2]

How the network is used
- Indoor cellular coverage for guests, including AT&T subscribers handed onto the hotel network through MOCN, in a building whose dense materials block outside signals (campus and in-building).[1][2]
- A single network for staff communications.[3][1]
- Wireless sensors for temperature, humidity and other environmental conditions, and AI-assisted video surveillance (video surveillance).[3] Light Reading reported that the hotel tested these applications with Comcast and Ballast in 2022.[2]
