Spectrum Sharing and Microwave Relocation

When the PCS bands were auctioned in 1995, more than 4,500 U.S. point-to-point microwave paths already used the 1.9 GHz band. Because the new PCS systems and the incumbent microwave systems would operate in the same frequency band, the FCC established a series of rules for both parties to share the spectrum. The ability to meet these FCC requirements is essential to maintaining and upgrading your PCS network.

FCC Requirements, Part 24

The FCC requires that each PCS operator:

• Provide interference protection to the incumbent microwave systems using the industry-accepted interference calculation methods contained in Telecommunications Industry Association (TIA) Telecommunications Systems Bulletin (TSB) 10F
  
• Distribute prior coordination notices (PCNs) to all incumbents within a specified coordination distance at least 30 days prior to operation
  
• Submit PCS site information to the cost-sharing clearinghouses prior to operation
  
• Follow relocation guidelines when relocating incumbent systems to an alternate frequency band
  

Relocation Guidelines

In the event that a PCS system would cause harmful interference to microwave systems, the PCS operator can approach the incumbent to relocate their system to an alternate frequency band. The FCC sets strict guidelines for this relocation process including mandated negotiation/relocation periods. Learn more about the negotiation/relocation guidelines for the PCS band.
