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 base transceiver station (BTS) or a baseband unit [1] (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers.
A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. [1]
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 ...
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.
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.
4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.
