- exception would conflict with any other decisions the Commission has made concerning the differences between common carriers and non-common carriers. We seek comment on this proposal and any alternatives thereto. 2. Shared bands . Several frequency bands are used for TV Broadcast Auxiliary Services, Cable Relay Service (CARS), Private Land Mobile Radio Service, and Fixed Microwave Services. For example, Sections 74.644, 78.108, 101.143, and 101.803(b) set out minimum path lengths and appropriate power reductions for many of the same bands. However, Section 101.803(b), which regulates LTTS, requires compliance with the technical rules provided in Parts 74 and 78 of our Rules, which are different from those contained in the Part 101 rules. In addition, we understand that some confusion exists concerning

- Isotropic Radiated Power (EIRP) for Short Paths There are several rule sections used for TV BAS that work in tandem to regulate the amount of power that can be used at a specific station. Specifically, Section 74.636 of the Commission's rules limits, for some frequency bands, the maximum EIRP for which a TV BAS station can be licensed, and Section 74.644 specifies the minimum path length for which the maximum EIRP will be authorized for fixed links. Applicants proposing path lengths shorter than those specified in Section 74.644 are required to reduce power in accordance with the equation provided in rule section 74.644. In its petition, TIA points out that the current equation requires a steep reduction in EIRP for paths

Currently, the equation specified in Section 74.644 requires a steep reduction in EIRP for paths slightly
