OVERVIEW OF MOBILE TECHNOLOGYMobile technology refers to the portable technology that is carried around by the user.Usually, the technology is characterized by moveable computer devices, two-way devices ofcommunication, and networking technologies that connect these devices. The mobile technologyindustry is growing and the number of mobile technology devices use is over 3 billion globallywith over 1.87 billion workforces as of 20222. The current mobile technology is characterized bydevices such as tablets, watches, and smartphones that are internet-enabled. Most of the modernmobile technology devices are designed in ways and features that are comparable by theircapabilities. These include making devices that have read-only memory (ROM),microprocessors, random access memory (RAM), speaker and microphone, liquid crystal display(LCD), and digital signals processors (Fox, 2019). However, these devices have differentphysical features and technicalities and different expansion capabilities as well. There arewireless technologies that are used in the connection of these devices and enable the linking andcommunication of the mobile technology devices. It’s through the wireless connections that thedevices can share data, access applications, and share voice notes as well.Communication with Cell SitesCommunication via mobile technologies entails radio frequency (RF) signals that areprojected in many directions. Essentially, cell phones have two-way radios that allow asimultaneous reception and transmission of radio waves. Networks operate by allowing the radiowaves to be picked by the base station that is near and available referred to as cell sites. The cellsites are set up in a wide geographical area and the signals created by the system constantly roamfrom a single cell area to other signal bases, creating stronger communication mobility. Multiple3base stations use different radio frequencies that do not collide (Kar & Sanyal, 2018). Thefrequency spectrum, mobile technology devices, and the signal tower create the Radio AccessNetwork (RAN), as presented in the figure below. This, therefore, forms the basis of mobiletechnology devices delivery that creates robust and consistent network infrastructure forcommunication networks.Cellular to Cellular CommunicationsCellular-cellular communications refer to what happens when a communication attemptor a call is made. Once a cell phone has been turned on, it makes the trial of locating SystemIdentification Code (SID) on the control channels to establish connectivity (Bae et al., 2019).Once a SID has been recognized, it makes a comparison of that SID with the programmed SID ofthe device, and if they are a match the phone verifies that there is communication with thedevice. The device, therefore, transmits registration requests together with Mobile TelephoneSwitching Office (MTSO) and the SID which locates the device in a database.When the cell phone moves towards the edge of the connected cell site, the base stationof that cell will not have the diminishing signal strength. At the same moment, the base cellstation to which the mobile device is moving will be able to pick up this signal and an increasingstrength signal is seen. The two base cell stations can coordinate network handover to oneanother using the MTSO. At some given point, a mobile device will be able to get signals oncontrol channels that direct it to make changes in frequencies. This switches the cell phone to thenew suggested cell site.Mobile Switching CentersThe Mobile Switching Centers (MCS) describe the network switching subsystemfoundation. This way, MSC handles multiple functions such as routing, call set up, and releasing.4Additionally, it also supports SMS routing, conference calls management, network interfaces,service billing, and fax. A cell in motion can switch from a single cell tower to another celltower, ensuring there is seamless communication for the device user. MSC acts as traffic controlof networks by facilitating network rerouting. Therefore, this makes the MSC important to thenetwork components that have control over the elements in the subsystem network switches(Davronbekov & Matyokubov, 2020). Additionally, its acts as a core component in the cellularnetwork switching subsystem (NSS) which is associated closely with ensuring the following;a) Signals are conveyed over various connections or separate channels for the conveyanceof caller address identity, alerting the station that was called.b) Connections are established through network switching used for the whole conversationalcall duration.c) The establishment and disconnection of switching networks connection through signalinformation processing, control, and supervision.Base Switching Subsystem (BSS)Base Switching Subsystem (BSS) is usually part of GSM network which is made up ofbase transceiver station (BTS) and the base station controller (BSC) (Gu & Peng, 2010) The BTSrefers to network equipment that consists of transceivers, amplifiers, duplexes and antennas thatencrypt and decrypt with BSC. The BSC describes the network elements used in controlling andmonitoring several base stations and offers the interface between cell sites and MSC.The technology of Mobile NetworksMobile devices network technology describes the technology that supports data and voiceconnectivity without wire connections (wireless connections). There have been severalgenerations of cellular technologies such as the 1G, 2 G, 3G, 4G, and 5G. 1G connection was5based on analog signals and was associated with poor connections, low call qualities, and poornetwork security. 2G, the second connectivity connection replaced 1G because it had the abilityfor data encryptions and the 3G came along, offering more effective global transmissions. 3Galso made it possible for many high transmissions such as multimedia. The 4G is the currentstandard connectivity that provides more reliable calls connectivity and access to multimedia likemusic streaming and provides high-security levels that prevent data loss and eavesdropping. Thelast is the 5G, which most technologies are rushing to create. As compared to the previousgenerations, 5G has better speed, is more responsive, and has the strength to connect to multipledevices (Salih et …
