CTIA is always an interesting event especially the Tower Technology Summit. Today, I sat on a CTIA panel session to discuss the topic of “Microwave Backhaul Gaining Momentum”, along with two other colleagues from other microwave companies. The purpose of the session was to discuss the proposed changes to FCC Part 101 rules listed in 10-153 for fixed microwave links. Sounds pretty dry? Not really, as the proposed changes being considered by the FCC are intended to ease some of the restrictions placed on microwave links operating in the lower frequency bands, and also to enable more flexible use of technologies like Adaptive Modulation. In short, good ideas to make microwave even more cost effective for operators.
Each panelist gave a short talk on updates to the new proposed changes and what these changes mean for microwave backhaul. At the high level, there was clear agreement that the current rules are pretty old, outdated, and need modification to support the industry’s migration to all IP. However, there was broad recognition that changes probably won’t happen overnight!
The panel had a heavy focus on total cost of ownership (TCO) for microwave solutions, and how smaller antenna sizes can play a significant factor in reducing costs. I presented our view of a TCO model (that we recently presented in more detail on a recent Strategies for Lowering Your LTE/4G Backhaul Bill webinar with the WCAI ), and discussed technology and network design approaches to utilize smaller antennas.

LTE backhaul capacity requirements and backhaul options for small cell architectures were also topics of discussion. Our perspective on this is that LTE backhaul capacity requirements are often over-hyped and overstated, leading to poor backhaul decisions, which seemed to garner a lot of “head-nods” from attendees. There was also general agreement from the panelists that new backhaul solutions were needed to address the small cell backhaul challenge and a “one-size-fits-all” product would surely not meet the needs.
We are just touching on the tip of what will become a hot topic of discussion in the months and year ahead. For more on this topic check back next week for my follow up post to Microwave Total Cost of Ownership (TCO) Pt. 1.
