A wireless wide area network (WWANs) is “a network that spans a geographical areas as large as an entire country or even the entire world.” (Olenewa, 2013, p. 480) The cellular phone advance technologies offer organizations the ability to establish WWAN for employees to connect and access data. Interestingly, locations, where cellular networks are unavailable satellite technology, provides users an avenue to connect to the internet.
Cellular telephony is a sophisticated wireless communication technology. The two key factors to understand how mobile telephony works are cells and digital transmitters. A cell is the coverage area divided into smaller sections. (Olenewa, 2013, p.360) Cell coverage can range from a thousand feet to ten square miles with a transmitter and receiver in the center. The transmitter connected to the base station communicates to a mobile telecommunication switching office (MTSO). The second key factor is a digital transmitter, while cellular phones operate at a lower power level, which enables cells to not experience interference with another cell.
A cellular phone scans frequencies configured to use and listen to for any broadcasts from the nearest base station.
If the phone or subscriber identity module (SIM) matches the broadcast, then the phone will transmit a registration request to the base station to the MTSO uses to track cell phone location.
If the SID request does not match, the phone goes into a roaming status.
A call initiated, the MTSO locates the phone and assigns a frequency for the communication. The MTSO will then notify the control channel, and the telephone and transmitter will algin the frequency, and the connection sealed.
A phone signal strength that decreases due to moving away from a cell, the base stations and MTSO will coordinate with the control channel to provide a more reliable signal to another cell, referred to as a handoff.
The process of phone, transmitter, and frequency changes will occur as required or location.
Describe wireless wide area networks (WWANs) and how they are used.
The WWAN (Wireless Wide Area Network) is a communication technology that was designed to cover an entire country or geographically continents of the world. It facilitates connectivity to the Internet with the aid of satellite technology and are used to access corporate networks and to conduct various types of business across the globe or in an entire country such as the United States.
2. Explain how cellular telephony functions.
Cellular Telephony technology are preprogrammed during manufacture with special codes to identify owners, and the carrier (service provider) that provides the SIM (Subscriber Identity module) card and its works are based on two keys. (1). The division of the coverage area into smaller individual sections, called “CELLS” that range from a few thousand feet in diameter to approximately 10 square miles (26 square kilometers). Positioned in the center of each cell are a transmitter and a receiver which the mobile devices near that cell communicate via Radio Frequency (RF) signals. Functions: The transmitters are linked to a base station or stations connected to a Mobile Telecommunications Switching Office (MTSO) – which controls transmitters and serves as the linkage point for cellular phone network and the wired telephone environment. (2). the functionality of cellular telephony technology employs digital transmitters which allows digital cellular phones to operate at a low power level and in the process, enables the confinement of the signal in the cell of a single phone to prevent interference with any other cells. The signal’s frequency level remains within the cell area and could also be used in other cells at the same time; rather than in adjacent zone – known as “frequency reuse.
