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.
The main benefits for an end user are the following: "5 bar" coverage when there is no existing signal or poor coverage; Higher mobile data capacity, which is important if the end-user makes use of mobile data on their mobile phone (may not be relevant to a large number of subscribers who instead use WiFi where femtocell is located)
A digital loop carrier (DLC) is a system which uses digital transmission to extend the range of the local loop farther than would be possible using only twisted pair copper wires. A DLC digitizes and multiplexes the individual signals carried by the local loops onto a single datastream on the DLC segment.
5G Broadcast (5GB), officially known as LTE-based 5G Terrestrial Broadcast, is a system for the distribution of television and other broadcast media content via terrestrial radio broadcast networks based on downlink-only LTE technology. [1] [2] 5G Broadcast focuses mainly on mobile use cases like smartphones and in-car radio.
Since only one wireless device can transmit at once, wireless transmissions are doubled (router to the repeater and then repeater to the client versus just router to the client), and so: Wireless throughput is reduced by at least 50%. [1] Wireless interference (e.g., with other networks on the same channel) is at least doubled.
While the repeater station is designed for simultaneous reception and transmission, mobile units need not be equipped with the bulky and costly duplexers, as they only transmit or receive at any time. Mobile units in a repeater system may be provided with a "talkaround" channel that allows direct mobile-to-mobile operation on a single channel ...
Some ADSL loop extenders aren't repeaters, but instead convert to a different signal (like G.shdsl) that fares better over extreme distances. This is because G.shdsl can use the lower frequencies that ADSL reserved for voice use. Crosstalk has been analyzed using T1.417 Method B and found to be compliant.
An autopatch, sometimes called a phone patch, is a feature of an amateur radio (or other type of two-way radio) repeater or base station to access an outgoing telephone connection. [1] Users with a transceiver capable of producing touch tones ( DTMF signals) can make a telephone call , typically limited by settings in the autopatch module to be ...
