2. 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.

   These are the QTM052 mmWave antenna module family and the QPM56xx sub-6 GHz radio frequency (RF) module, and they'll pair with the company's previously announced Snapdragon X50 5G modem -- making ...

4. Smart antenna - Wikipedia

   en.wikipedia.org/wiki/Smart_antenna

   Smart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target.

   The good news: Apple's AirTag is one of the most powerful trackers you can get, leveraging the iPhone like no other device can. The bad news: "iPhone" is where AirTag compatibility ends.

6. Signal strength in telecommunications - Wikipedia

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

   In telecommunications, [1] particularly in radio frequency engineering, signal strength refers to the transmitter power output as received by a reference antenna at a distance from the transmitting antenna. High-powered transmissions, such as those used in broadcasting, are expressed in dB-millivolts per metre (dBmV/m).

7. 'Hovering' antennas promise speedy 5G phone networks - AOL

   Wireless networks already have to deal with increasingly crowded waves, and that's only going to get worse when 5G rolls around. Any boost to the signal could lead to a big jump in performance ...

8. Wireless device radiation and health - Wikipedia

   en.wikipedia.org/wiki/Wireless_device_radiation...

   The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).

9. Omnidirectional antenna - Wikipedia

   en.wikipedia.org/wiki/Omnidirectional_antenna

   Omnidirectional antennas are widely used for radio broadcasting antennas, [3] and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.
