In macro networks, coverage drives design. Indoors, capacity often drives design, especially for 4G. A stadium or convention center may require hundreds of small cells or DAS nodes per square kilometer, while a rural hotel may need only one repeater.

| Generation | Service | Required RSRP (LTE) / RSSI (2G) | Signal-to-noise (dB) | Blocking probability | | --- | --- | --- | --- | --- | | 2G | Voice/SMS | > -85 dBm | > 9 | < 2% | | 3G | Voice/data | > -80 dBm (CPICH RSCP) | Ec/Io > -12 dB | < 5% | | 4G | Data (10 Mbps down) | > -105 dBm (RSRP) | SINR > 3 | < 10% | A practical guide for 2G
Note: 4G RSRP is lower due to better coding and HARQ, but SINR must be tightly controlled.
The cornerstone of indoor planning is the Distributed Antenna System (DAS).
