Cellular Networks Comparison - Essay Example

Cellular Networks Comparison Comparison of the network architecture of UMTS, EV-DO, LTE, WiMax, and Satellite A cellular network is a wireless set-up spread over geographical areas called cells, all working closely with at least one permanent site transceiver also called a base station or cell site. When base station or cell sites are linked together they make available radio coverage on an extensive geographic space. Thus permits an enormous amount of portable transceivers like pagers, mobile phones and much more to converse with one another as well as with static transceivers plus handsets whichever in the network, through base stations, while numerous transceivers are passing over one cell through broadcast (Sesia 22)1. Some the cellular networks include; UMTS, EV-DO, LTE, WiMax and Satellite (Kostas 38)2. The UMTS (Universal Mobile Telecommunications System) is known as the third world (3G) wireless frequency that is used on the (GSM) Global System for Mobile communication, to convey text, audiovisual, digitized voice as well as multimedia (Markus 62)3. The network architecture of UMTS entails simply of enodeBs continuously on the network. The functional components of UMTS are User Equipment (EU), the essential network as well as the Radio Network System (RNS) which delivers then bring about air interface fort and the call processing of UMTS involves controlling the call operating layer nodes. The weakness of UMTS might be distortion and weak signal while its strength is linked to the high speed to transfer voice as well as mobile data (Markus 93).The EV-DO (Evolution Data Only or Evolution Data Optimized) is a procedure intended to transfer high speed moveable data as well as voice (Markus 72). EV-DO network architecture is centered on wireless Internet Protocol architecture while the functional components of EV-DO are the Core Network (CN), the Radio Access Networks (RAN) and the Mobile Station (MS). The call processing are boosted by IS -95 over high speed data period. The weakness of EV-DO may be distortion as well as weak signal while its strength is allied to the high speed to convey voice plus wireless data (Markus 493). LTE (Long Term Evolution) is a standard wireless communication, legally submitted as a contender for a 4G structure to ITU-T. LTE is still on Continual architecture network improvement radio technology and its functional component was tested publicized and the achievement of a 4G trial where it succeeded an extreme packet its strength broadcast rate of about 5 Gbit/s in the downlink consuming 100 MHz frequency bandwidth to a wireless place stirring at 10 km/h while LTE weakness might be distortion as well as streaming signal. The WiMax refers to Worldwide Interoperability for Microwave Access, the WiMax network architecture is built on the Internet Protocol based where the network is split into three rations called ASN (the access service networks,) the mobile stations (MS) and the connectivity service network (CSN) which runs Internet Protocol linkage (Goff 77)4. The functional components of WiMax cellular network are the BS (base station), the connectivity service network (CSN) as well as the ASN-GW (access service network gateway) (Goff 66). Call process of WiMax session is started once the mobile station (MS) effectively complete the method of linking into the network, thus necessitates opening BCE Basic Capability Exchange, the recording and verification and Internet Protocol obligations. WiMax Strengths is that it is easily accessed, inexpensive and applied effortlessly, WiMax has a wireless broadband that alternate to Cable (Goff 300) while WiMax weakness is that the set up cost is costly, strangely limited personnel may be capable, and WiMax networking safety might be weak (Goff 340). Satellite is a technology used to communication and is positioned into orbit by human endeavor. The functional component of human made satellite in the delivering of its mandate to cellular networks is to offer communication proficiencies to the globe, power source as well as a controls network to achieve predictable operations. The call processing of satellite is to take part with the GSM (Global System for Mobile Communication) to increase mobile accessibility (Markus 420). The weakness of satellite may be distortion as well as weak signal while its strength is allied to the high speed to convey voice plus wireless data (Markus 493) The similarities and differences of the cellular networks The similarity of the above cellular networks is that they link a wide geographical space. The various cellular networks conversed above allow the end user to be able to interconnect to one another over an extensive topographical space (Markus 45). They as well guarantee slightly reduced power consumed as equating to cable data as well as voice transmitter in reference to wireless transceivers that use less energy as compared to its job description. The difference of the cellular networks involves their competences to consume components and roles of all secured and public networks. Comparison of the network security of UMTS, EV-DO, LTE, WiMax, and Satellite The UMTS (universal mobile telecommunications services) network security is heightened by the GSM (global system for mobile communication) as well as the GPRS (general packet radio service). The UMTS authentication is done by smartcard request known to as USIM (Universal Subscriber Identity Module). It is as well authenticates public pass words amongst portable and BS to evade bogus occurrences (Lee 31). The EV-DO is secured by protecting session safety over re-authenticating the AT in the current session thus shield the session in movement from hacking hence defends the consumer packets. EV-DO is also guarded by authenticating as well as encryption purposes (Sesia 123). The LTE (Long Term Evolution) permits the cellular networks upsurge broadband bulk to sustain up to 10 times greater data tolls. A security network of the LTE is of NAS (Non- Access Stratum) in addition to Access Stratum that facilitates the success between User Equipment and core network (Sesia 43). The LTE similarly uses the USIM (Universal Subscriber Identity Module) it is a card that contains the subscriber uniqueness that could be continuous in the process of allocating of phone improvement. The WiMax network security detailed physical layer security which safeguards congestion and additional packet jamming, wireless authentication transmission, encryption in addition to third party invasion fortification (Sesia 48). Packet clambering involves occurrences that can be regulated with the corresponding downlink as well as uplink. Encryption is the first phase of resistance for the end users of WiMax cellular networks. This expertise involves enthusiastic PCs to manage and regulate base stations that which is extremely operational. Satellite network security comprises delivery of username as well as password for all peripheral in a network, presentation of unrestricted guidelines in addition to regulation, application of satellite security practices as well as exploitation of security devices like encryption (Markus 65). Firewalls are also being used as networks security devices against networks attacks. Firewalls safeguard movement by opening and closing network ports. The cellular networks usually have encryption for network safety. Encryption involved a method of creating crypto amenities at the network transmission level. These layers are connected with the linkage and course plotting among two finish points. Authentication is where by network necessitates verifying, logging the identity of the user against a network. This is through the use of PIN, biometrics, arithmetical certificates as well as smart cards (Sesia 72). Works Cited Hill, Goff. The Cable and Telecommunications Professionals' Reference.
