Bryon Gunnerson
Bryon's tenure in the wireless industry dates back to the early 1970’s. In the early 1980’s, Bryon joined McCaw Cellular with the responsibility of building out many parts of the wireless network. The company would eventually become a part of AT&T Wireless. Following his time at McCaw, Bryon assisted with the founding of Western Wireless and led the development of the network that would eventually become a part of T-Mobile USA. Bryon remained at T-Mobile for years leading the continued development of T-Mobile's western region.
After leaving T-Mobile, Bryon recognized a need for industry experts whose interests were not aligned with the national wireless carriers. To test that theory, Bryon worked with several municipal and private entities to correct issues with their wireless leases and developed new leasing programs. Through the results gained from this experience, it became apparent that wireless landlords and property owners, large and small, public and private, could benefit from the knowledge and expertise of a group of wireless industry experts.
In 2010, Bryon founded Gunnerson Consulting & Communication Site Services (GCCSS) to assist in several areas of the wireless industry:
- Low Latency, High Speed Network Development
- Wireless Network Development and Deployment for large and small entities
- Consulting Services for Wireless Landlords
- Site Management Services
