2. 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.

3. 4G-LTE filter - Wikipedia

   en.wikipedia.org/wiki/4G-LTE_filter

   4G LTE is the fourth generation mobile phone standard. In urban areas, the 4G uses a frequency band located between 1800 MHz and 2600 MHz, and therefore is quite far from the TV band for causing any type of interference problem. In rural areas, however, the major operators asked to use part of the UHF band.

4. 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.

5. 4G - Wikipedia

   en.wikipedia.org/wiki/4G

   The pre-4G 3GPP Long Term Evolution (LTE) technology is often branded "4G – LTE", but the first LTE release does not fully comply with the IMT-Advanced requirements. LTE has a theoretical net bit rate capacity of up to 100 Mbit/s in the downlink and 50 Mbit/s in the uplink if a 20 MHz channel is used — and more if multiple-input multiple ...

7. History of smart antennas - Wikipedia

   en.wikipedia.org/wiki/History_of_smart_antennas

   Antenna for LTE MIMO technology with 2 connections of offset indoor antennas. Smart antenna research led to the development of 4G MIMO. Conventional smart antenna techniques (such as diversity and beamforming) deliver incremental gains in spectral efficiency. 4G MIMO exploits natural multipath propagation to multiply spectral efficiency.
