Running head: Blog writingHOW 2G NETWORK WORKS?June 22, 2019INTRODUCTION TO 2G NETWORK2G is being regarded as the short generation for mobile technology. In other words, it canbe said that the 2G network is basically a type of cellular network that was commercially beinglaunched on the GSM standard in Finland by Radiolinja in the year 1991. On the other hand, itcan also be depicted that 2G network is being regarded as second generation wireless telephonytechnology that tends to replace analog 1G technology. This indicates that there is enormousdevelopment had happened in cellular technology. Additionally, the second-generation mobile technology has completely changed theconcept of mobile phones. The respective technology has enabled users to gain the advantages inthe form of the increased frequency band, high data transfer rate, and the wireless connectivity,etc. However, at present, the technology of mobile communication has evolved to 5Gtechnology. But, in the given blog we will gain a thorough understanding of the 2G networktechnology. In this regard, we will basically see the working process behind the respectivetechnology. Further, this blog will also entail about the benefits as well as the limitations that areassociated with the 2G network in an effectual way. FACTS AND FEATURES RELATED TO 2G NETWORKThere are some facts and features of 2G network examined. These features will assist anindividual in the task of assessing the 2G technology among different other forms of networktechnologies. The description in relation to the same is given below:For the processing purpose, digital signals are used instead of analog signals that arebeing employed in a 1G network.The digital signal processing that is being used in the 2G network will allow thenetwork to give support to the voice traffic and the data transfer.It connects mobile devices with the internet and the different other types of businessnetworks. 1

This is due to the fact that lack ofknowledge of the same will not enable individual to improve better understanding of the givennetwork. The details about all the technology are given below:FDMA (Frequency Division Multiple Access): FDMA is being defined as the channelaccess method that is being used in some of the multiple access protocols. Therespective technology gives the opportunity to the multiple users with respect to sendthe data by using a single channel of communication such as microwave beam or thecoaxial cable etc. In addition to this, it tends to divide the bandwidth of the channel intothe separate non-overlapping frequency of the sub-channels. In addition to this, hereeach sub-channels are allocated separately to the different users. The given form oftechnology is basically used in the satellite communication system as well as in thetelephone trunklines. On the other hand, the FDMA enables the call with regard to usevaried frequency and for this purpose, it splits calls into different small cells. Further, itis also examined that FDMA works best in the analog transmission but it does not meanthat it will not provide support to the digital transmission. Although it is giving servicesof digital transmission, the services which are being given by it is very much poor. TDMA (Time Division Multiple Access): It is also being regarded as another form ofmobile phone technology that is being used in 2G network. It is being regarded as thechannel access method that is being used in the shared medium method. The respectivetechnology gives the opportunity to the user with respect to sharing the channel of thesame frequency by dividing the signals into the different types of time slots in aneffectual way. In addition to this, it also allows the multiple stations to use the samemedium of transmission while using only some part of the channel capacity. In additionto this, the given technology was first used in the satellite communication system by theWestern Union. However, at present, it is extensively used in the passive optical2
