FirstNet Faces the Facts

FirstNet is facing technological challenges as it careens toward key decisions for the Nationwide Public Safety Broadband Network. That was the key takeaway when APCO held its Public Safety Broadband Summit in Washington D.C., May 13-14. In that context, backhaul continues to be a hot topic. Typically more of an afterthought in commercial telecom systems, backhaul becomes the 900-pound gorilla in the room when defining high reliability telecom networks such as mission-critical public safety networks. This is due to the extremely high cost of fiber—CAPEX for new runs and OPEX for leasing—as well as its proven lack of survivability in worst-case scenarios.

For example, during Superstorm Sandy, 25 percent of all affected commercial mobile sites were down, and most had to be propped up by temporary microwave radio backhaul solutions due to the lengthy time needed to replace the damaged fiber. Chief Dowd of NYPD provided insight into the situation stating that the network’s reliability is defined during worst-case conditions, not during sunny days.

Know Your Microwave Backhaul Options

If you look in the November issue of MissionCritical Communications, you will see an article by Aviat Networks director of marketing and communications, Gary Croke. In his article “Know Your Microwave Backhaul Options,” Gary covers:

  • Benefits of using indoor, outdoor and split-mount microwave radios in various scenarios
  • Rationale for choosing microwave over fiber (especially for LTE)
  • Deployability of microwave
  • Software-upgradeable capacity for “pay-as-you-grow” capex scalability
  • Cost contribution of towers over the first 10 years of LTE implementation
  • And more

What is Mission Critical Microwave?

Public safety agencies with first responder assignments, mobile service providers with national footprints, and utilities companies all have communication networks carrying mission critical applications. These networks require robust, secure and powerful microwave radios.  

So what are the defining characteristics of Mission Critical Microwave?

  1. Hybrid (TDM and IP): Native TDM, native IP. No proprietary emulation or encapsulation.
  2. RF performance: Superior system gain. Adaptive Coding and Modulation.
  3. Reliability: 100+ year proven terminal (1+0) MTBF.
  4. Strong Security: Secure Management to prevent unauthorized access. Secure payload encryption to prevent eaves-dropping.
  5. Bullet Proof Redundancy: Full port, card, system level redundancy. Integrated T1 loop switch (USA).
  6. Physical Design for Usability: Front access, no hidden cables. Compact footprint. Expansion port.

 But delivering Mission Critical Microwave extends far beyond products and deals with the way a company behaves and treats its customers including:
