Indoor Radio Planning A Practical Guide For 2g 3g And 4g 3rd Edition 2015pdf Gooner May 2026

Indoors, radio waves do not obey simple free-space path loss models. Instead, they encounter:

Indoor radio planning is crucial for ensuring reliable and efficient wireless network coverage within buildings. This process involves designing and optimizing the placement of antennas and base stations to provide adequate signal strength and quality throughout the indoor environment.

Scenario: A 1990s concrete building with poor macro signal. Legacy 2G microcells exist but no 3G/4G inside. Users complain of dropped calls in elevators and slow data near windows (macro interference). Indoors, radio waves do not obey simple free-space

Solution per the practical guide:

Results after deployment:

For a downlink (base to user):

Received power (dBm) = Tx power (dBm) – Cable/combiner loss (dB) + Antenna gain (dBi) – Path loss (dB) – Body loss (dB) + Fade margin (dB) Results after deployment : For a downlink (base

Example for LTE at 2.6 GHz:

Received power = 15 – 6 + 3 – 68 – 3 – 10 = -69 dBm (well above -105 dBm requirement) Received power = 15 – 6 + 3
