Penetration Measurements from Low-height Base Stations at, and MHz ”, NTIA Report TR, Institute for Telecommunication Sciences, Boulder, Colorado, September   As shown in Section IV-A, a higher base station antenna gain is needed for some frequency ranges and building types.

Hence, in this section, performance results are presented in terms of DL user throughput assuming a base station antenna gain of dBi. As we are primarily interested in coverage, the focus has been on simulating low-load cases. An infrastructure relay system that transfers information from a base station to a randomly located mobile station (MS) using fixed-location relay stations (RSs) is studied.

RRC protocol requirements are specified in TS Receiver and Transmitter Performance Because of the small duplex distance (45 MHz) and duplex gap (10 MHz), with the same duplexer technology and size, the MHz duplexer insertion loss in a UE is expected to be.

Hence, in this section, performance results are presented in terms of DL user throughput assuming a base station antenna gain of dBi.

As we are primarily interested in coverage, the focus has been on simulating low-load cases. The value of "Wge" is dB at MHz and dB at MHz.

~ L o s s = Loss(in) - Loss(out) = a d - G h h+af log(!)+aLos LOS + W (2) where ~ L o s s is the building penetration loss, Loss(in) is the propagation loss between the BS and the receiver inside the building, and Loss(out) is the propagation loss between the BS and the receiver.

Precise characterization of in-building penetration is difficult, a rough approximation of an average penetration loss μi around 10 to 15 dB and a standard deviation σi around 6 dB seems to be the norm in published studies.
