20W BTS Tx power If DL only considered: -SINR requirement ≈ -6dB => RSRQ>-16.9dB, empty serving cell RSRQ>-17.7dB, fully loaded serving cell RSRP>-130dBm (1dB interference assumed).Throughput requirement 500/64kbps (DL/UL).Typical coverage requirement is that 95% of the measurement samples is fulfilling the criteria.Coverage criteria for field measurement can be estimated with link budget tool.In these situations, a cell phone signal booster for home, office, or vehicle can solve your reception problems.11 © .ltdFor internal use only Low areas around lakes, rivers, and gullies can also experience problems-there is signal, but it’s passing way over your head.ĭense urban areas with tall buildings have a different set of problems: Sometimes the top floors of buildings, forty or fifty stories up, can’t get reliable cell signal because cell tower antennas are aimed at lower elevations. If you’re outdoors, dense forest and hills will reduce or block cell signal. Stucco with wire mesh, metal roofs, large logs, and vapor barriers in attics also impede cellular signal, as will a large concrete building between you and the cell tower. Many building materials-including concrete, metal, low-e glass, wood, and plaster-reflect or absorb cellular frequencies, preventing them from penetrating the building and reaching your phone. It’s possible to be close to a cell tower but still be receiving weak cell signal. Physical barriers block cellular transmissions
