Cell phone towers are everywhere, but for many people, they just blend into the landscape. Although people don't often think about cell phone towers, they are absolutely vital to the wireless infrastructure that powers our world.
The terms "base station" and "base station" are often used interchangeably, but in reality, each term stands for different things. Before we dive into the types of base stations and base stations you need to know, here are some quick definitions:
Base chaw nres tsheb
Txhua yam khoom siv (antennas, vaj tse, thiab hauv av) siv los xa xov tooj ntawm tes ntawm cov khoom siv mobile thiab receivers. Feem ntau suav nrog transmitter/receiver, GPS, backup power, base station receiver (BTS), backhaul connection, etc.
Cell xov tooj ntauwd
Lub cev qauv uas lub kav hlau txais xov txuas nrog. Qee lub xov tooj ntawm tes tuaj yeem txhawb nqa ntau tus neeg ua haujlwm wireless, kev nyab xeeb rau pej xeem, lossis kev sib txuas lus hauv tuam txhab. Ntauwd yuav yog tus tswv los ntawm tus neeg teb xov tooj wireless lossis tus neeg thib peb thiab xauj rau ib lossis ntau tus neeg ua haujlwm. Raws li koj yuav pom hauv qab no, tsis yog txhua hom ntawm lub vev xaib raug teeb tsa ntawm lub xov tooj ntawm tes.
Tam sim no peb tau paub cov hauv paus ntsiab lus, cov hauv qab no yog cov feem ntau hom cellular base stations thiab cellular yees.
Base chaw nres tsheb hom
Cell xov tooj ntau qhov chaw
Kev pab: 0.5 mus rau 25 mais
When you hear the term "cellular base station," you usually think of towers. A cell tower is a physical structure designed to support one or more cell sites. Read on to learn about the four most common types of signal towers.
Ru tsev qhov chaw
Kev pab: 1.5 mus rau 25 mais
Rau lub ru tsev systems, kav hlau txais xov thiab cov khoom siv kis tau tus mob raug ntsia rau ntawm lub ru tsev ntawm lub tsev. Cov khoom siv txuas nrog rau cov khoom siv hluav taws xob rau pej xeem ntawm qhov chaw, thiab qhov backhaul fiber optic kev twb kev txuas yog coj los ntawm lub xov tooj tseem ceeb demarcation point ntawm lub tsev. Qee zaum, yog tias lub tsev nyob hauv qhov chaw zoo tshaj plaws ntawm qhov chaw ntawm tes, tus tswv tsev xauj tawm nws lub ru tsev mus rau lub wireless cab kuj.
Cell me me
Kev pab them nqi: 1/10 ntawm thawj mais, 2 mais ntawm ib leeg
Ib lub xovtooj me me yog ib lub xovtooj ntawm ib lub xovtooj uas me me, lub zog, thiab lub vojvoog npog dua li qhov chaw macro cell. Cov hlwb me feem ntau yog siv los ua ib feem ntawm lub network densification txoj kev npaj kom muaj peev xwm tag nrho ntawm lub network. Vim lawv qhov loj me, cov roj teeb me me tuaj yeem teeb tsa yuav luag txhua qhov chaw, los ntawm cov khoom siv hluav taws xob mus rau lub tsev ru tsev.
Sab nraum zoov Distributed Antenna System (DAS)
Kev Pabcuam: 1/10 ntawm 1 mais ntawm ib qho ntawm thawj mais
A distributed antenna system, or DAS, is, yes, an antenna network that transmits and receives cellular signals on an operator's licensed frequency. The outdoor DAS consists of a "hub", where necessary equipment is centrally installed. The antenna locations are strategically separated to cover the required area. The antenna location is called a node, and is connected to a hub via a fiber optic cable. There, the node is connected to the transmission equipment.
Sab Nraud DAS feem ntau tshwm sim nyob rau hauv cov cheeb tsam uas nws nyuaj los yog tsis yooj yim sua kom ntxiv ib txwm yees rau zoning cov cai. Cov kav hlau txais xov feem ntau yog ntsia rau ntawm cov qauv uas twb muaj lawm, xws li cov ncej hluav taws xob.
