Cellular Network Architecture | PDF | 4 G | 3 G An in depth guide on the architecture of a mobile/cellular network. we'll study about all the constituents and how they work in tandem to place a call. A cellular network is formed of some cells. the cell covers a geographical region and has a base station analogous to 802.11 ap which helps mobile users attach to the network and there is an air interface of physical and data link layer protocol between mobile and base station.

Cellular Network Architecture Diagram

Cellular Network Architecture Diagram Because of this, today's core network architecture resembles what we show in figure 1: the union of multiple core networks from different technologies (i.e., 2g, 3g and lte). the overall. The architecture of different generations of mobile cellular technology from 2g to 4g. the core technologies have moved from circuit switching to the all ip evolved packet core (moving right to left). The cellular network allows a user to connect wirelessly to the pstn (public switched telephone network). to really appreciate what technology has done for us all in the evolution of cellular networks, let’s take a brief look at what pstn looked like initially. Cellular architecture is constituted of the following −. a network of cells each with a base station. a packet switched network for communication between the base stations and mobile switching centers. in all cellular systems, land area is divided into a number of cells each with its radio service.

At&t bell labs designed a cellular structure to reuse frequency. no two adjacent cells use the same frequency. 832 channel pairs in each area. 416 pairs per carrier. on towers, roof tops, water tanks, utility poles, good source of income for utility companies, cities, schools, churches, hotels,. As shown in figure 3, the mobile cellular network consists of two main subsystems: the radio access network (ran) and the mobile core. the ran manages the radio resources (i.e., spectrum), making sure it is used efficiently and meets the quality of service (qos) requirements of every user. Radio resource control: extra control& state . 1a. phy: 802.11a/b/g/n/ac (tdma, ofdm) 1b. mac: csma ‐ca (contenon ‐based) . 2. from access to core gateway . 2a. within one network 2b. integrated (e.g., layer ‐2 tunneling from base staon to core switch) . 2c. control plane 2d. It uses a circuit switched network architecture that divides the radio spectrum into several channels. the 2g network architecture comprises three main components: mobile station (ms): this includes the mobile phone and the sim card.
