3. Signal strength in telecommunications - Wikipedia

   en.wikipedia.org/wiki/Signal_strength_in...

   For very low-power systems, such as mobile phones, signal strength is usually expressed in dB-microvolts per metre (dBμV/m) or in decibels above a reference level of one milliwatt . In broadcasting terminology, 1 mV/m is 1000 μV/m or 60 dBμ (often written dBu). Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some receivers

4. Mobile phone signal - Wikipedia

   en.wikipedia.org/wiki/Mobile_phone_signal

   A mobile phone signal (also known as reception and service) is the signal strength (measured in dBm) received by a mobile phone from a cellular network (on the downlink). Depending on various factors, such as proximity to a tower , any obstructions such as buildings or trees, etc. this signal strength will vary.

5. In-Building Cellular Enhancement System - Wikipedia

   en.wikipedia.org/wiki/In-Building_Cellular...

   As the industry evolves, most MNO networks are now made up of 3G based services and are migrating towards 4G based services. In-building cellular enhancement systems designed for 2G or primarily voice-based services may not be sufficient to support 4G services since signal strength and signal quality specifications become more stringent as the applications move from a voice-centric paradigm to ...

6. Cellular repeater - Wikipedia

   en.wikipedia.org/wiki/Cellular_repeater

   A cellular repeater (also known as cell phone signal booster or cell phone signal amplifier) is a type of bi-directional amplifier used to improve cell phone reception. [citation needed] A cellular repeater system commonly consists of a donor antenna that receives and transmits signal from nearby cell towers, coaxial cables, a signal amplifier, and an indoor rebroadcast antenna.

7. Path loss - Wikipedia

   en.wikipedia.org/wiki/Path_loss

   The environment will produce several deflections of the direct signal onto the antenna, where typically 2–5 deflected signal components will be vectorially added. These refraction and deflection processes cause loss of signal strength, which changes when the mobile antenna moves (Rayleigh fading), causing instantaneous variations of up to 20 dB.
