The introduction of Wi-Fi 6E and the push to utilize the 6 GHz spectrum for mobile 5G are presenting increasing interference risk to existing operators using fixed links in the 6 GHz FCC bands. In this article we look at one recent instance of interference from an unauthorized use of a point-to-multipoint (PTMP) radio system that was operating in the licensed L6 GHz spectrum that severely impacted the operation of a newly deployed 6 GHz point-to-point (PTP) microwave link, how this was discovered and what steps were taken to resolve it.

When considering a Multi-Band solution, users are usually interested in accessing the multi-gigabit high capacities available at the millimetre-wave frequency bands at 80 GHz, supported by the robust operation of microwave radio. A tightly integrated radio solution that provides a seamless single transport interface for users makes Multi-Band a no-brainer for Mobile Service Providers, WISPs and Private Network operators.

Telecoms network operators are striving to achieve the goal of 99.999% availability on an individual link basis, which translates to a mere 5 minutes of allowed downtime per year. To achieve this many operators add physical equipment protection in the form of N+N configurations and/or space diversity path protection. Techniques like adaptive modulation and automatic transmit power control have proven very successful in achieving more resilient networks by mitigating the adverse effects of radio propagation.

5G is fast becoming a reality in many parts of the world. According to the Global Mobile Suppliers Association (GSA), 461 operators in 137 countries/territories are now investing in 5G, including trials, licenses acquisition, planning, deployment, and launches. Of those, 176 operators in 72 countries/territories had launched one or more 5G services.

Today, Public Safety networks need to support a growing range of customers, applications, and services. Along with the increasing amount of mission-critical traffic to support public health and emergency responses, most agencies are also supporting traffic involving other agencies, consolidating inter-, intra-, and adjacent agency traffic over a common infrastructure.

Natural or man-made disasters don’t provide advance warnings and when they occur, they can immediately and significantly impact networks. Fallen trees, bridge outages, and construction catastrophes can cut fiber. High winds can destroy microwave antennas and RF units. Floods can topple overhead lines and wreck equipment depots. Fires can destroy equipment sheds. Terrorist attacks and acts of vandalism can bring down a network in seconds.
