The Modern Rules Of Cellular Mobile
A cellular mobile or mass network is a worldwide communication network in which each connection is wireless. The network consists of various cell sites or base stations, usually served by one or more fixed-location transmitters, but in more commonly, several cell sites or primary base stations. Most mobile devices communicate with these base stations or cells through a network's primary relay stations. Cell sites and base stations are usually strategically located to provide service to the most people. In this way, many people can share the same connections at the same time without much difference in quality or performance.
Cellular mobile devices and services are increasingly becoming a necessity for businessmen and individuals alike because they can save a lot on the cost of long-distance calls, aside from being more convenient. This type of mobile phone service offers the convenience of calling anywhere anytime with a compatible phone, while at the same time conserving money and other resources. For this reason, cellular operators and providers have come up with more sophisticated ways of operating their systems and networks. Through this, they are able to offer more services and better capabilities for their customers.
Cellular mobile phones operate on different frequencies. The frequencies allow cell phones to pick up signals from other nearby cells and transmit them to the user's cell. Cell phone companies usually offer two types of frequencies for their products. One is CDMA, which are considered as the international standard, and the other is GSM, which are the worldwide standard used in making mobile phones. However, CDMA cellular phones can only receive and send data at a speed of 40 Mbit/s; while GSM cellular phones can transmit and receive data at a rate of 10 Mbit/s.
CDMA cellular phones use a frequency that allows them to only receive and send data at a specific speed. As a result, it is unable to send or receive information at a higher bandwidth. GSM cellular networks, on the other hand, work with any frequency, and therefore it can accommodate the demands of a wide spectrum of users.
Aside from the technology and features, another thing that separates these two is the way they are used. GSM cellular networks are accessed by using a SIM card. In contrast, CDMA cellular networks use the so-called transceivers, which receive and send signals within a small range. These signals are usually picked up by base stations. In both cases, these signals are converted into digital data that can be sent to an area code and/or an autonomous area code.
In order for cell phone users to use CDMA and GSM cellular networks, they usually insert a small chip into their telephone handset. This device, which is known as a transceiver, is then connected to an antenna. The antenna receives the transmitted radio signals and converts them into electrical pulses. The converted signal then causes the transmitter to generate radio waves, which can be picked up by the different cells in the vicinity.
To use GSM, the transceiver must have a specific frequency. Once the signal has been acquired, the receiver of the device can determine the location of the particular mobile unit and activate it. It then sends the transmitted radio waves out to the different cells within the area. Because of this, the entire process takes only a few seconds.
In contrast, CDMA cellular phones operate using a different system. Rather than being activated by a signal, the rf signal is used instead. The rf signal is generated by the base station and the transmission requires a one time fee. The fee is charged because the base station's job is to ensure that the transmission takes place. Because of this, it is able to maintain constant communication with the mobile unit and ensures that all calls are answered promptly.
