Imagine a highway with one lane reserved for trucks that is virtually deserted and another lane clogged with cars that are restricted from using the open lane. Something similar could happen in the wireless world as global mobile data usage continues to skyrocket. Fortunately, Dynamic Spectrum Access (DSA) technologies and evolving spectrum regulations are underway. The goal is to open up underused spectrum exclusively licensed for a single purpose to shared use with other purposes—in this case, wireless access.

Cisco is very active in expanding use of DSA techniques for unlicensed use in the 5-GHz, TVWS, and 3.65-GHz bands. Our enterprise-class Wi-Fi radios have state-of-the-art intelligence for co-existence and interference mitigation. Cisco actively works with standard bodies and regulators to advance DSA technology and expand shared access.
