Wireless Telephony :Features and Application ~ Webtechnology5

Wireless telephony

Wireless telephony is the technology that operates by transmission of information through space; there is no physical or fixed connection in between sender and receiver devices. By using the wireless telephony peoples can be transceivers the information from airplanes, driving cares, swimming pools and while jogging in the park. Wireless telephony come in two basic varieties:

1. Cordless phones (sometimes called portable telephone) and

2. Mobile phones (sometimes called cell phones).

Cordless phones are devices consisting of a base station and a handset sold as a set for use within the home. These are never used for networking, because of its limited range; usually it’s expected range up to the same building or some short distance from the base station. The base station attaches to the telephone network the same way a corded telephone does.

Mobile phone is one another generations of wireless telephony that can highly feasible to make and receive calls over a radio frequency carrier while the mobile user is moving within a telephone service area. The radio frequency is responsible to establish a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Most modern mobile telephone services use cellular network architecture, and therefore mobile telephones are often also called cellular telephones or cell phones. The Mobile phones wireless telephony has gone through three distinct generations, with different technologies:

Analog voice.
Digital voice.
Digital voice and data (Internet, e-mail, etc.).

A wireless telephony can be used like a local area network (LAN) with voice capability and can be part of a larger network or can be connected into the telephone system. It’s real time example is Personal Access Communications System (PACS). It is a type of wireless telephony compatible with telephone sets, answering machines, fax machines, and computers.

Features of wireless telephony:

As high acceptability of wireless telephony across world the wireless telephony require a different set of features are as follows;

1). High Capacity Load Balancing: The origin of wireless telephony to cover the smartphones, tablets, e-readers devices, etc. With the increased demand on the wireless telephony infrastructure, it must require incorporate high capacity load balancing. The actual mean of load balancing is that when one access point is overloaded or number of users reaches up to the limit, the wireless telephony allows the system to actively shift wireless device users from one access point to another depending on the capacity that is available.

2). Scalability: The growth rate in popularity of new wireless gadgets has will only continue to grow. A wireless telephony needs to have the ability to start small if necessary, but expand in terms of coverage and capacity as needed without having to overhaul or build an entirely new network.

3). Mobility: Wireless telephony is more popular for their mobility features that assigning and controlling the wireless links for network connections. It provides the alerting function for wireless telephony devices for data completion to a wireless terminal.

4). Centralized Management: In current high technology world wireless telephony are much more complex and it may consist of hundreds or even thousands of access points. Therefore, wireless telephony will require a smarter way of managing all the access points within specified network that network is named as centralized management. Updates and configuration changes should be made once and the system updates all access points across over wireless telephony network.

5). Real Time Wireless Visibility: For all wireless telephony devices, administrator need to have the ability to see the wireless telephony network users in real time, what type of device uses are using, what type of coverage shows in that area, and the status of the different networking components that may affect the use of that device et. The wireless telephony administrator needs to be able to see what’s going on in order to address any issues.

Applications of wireless telephony:

As the hugged amount of valuable features wireless telephony highly acceptable by industry and common people in their daily life. Various real time application of wireless telephony are as follow;

To provide wireless data communications:

Wireless data communications are an essential component of mobile computing. To achieve fast and secure data transmission with high speed wireless telephony is highly advance technology. The various available technologies differ in local availability, coverage range and performance, and in some circumstances, users must be able to employ multiple connection types and switch between them.

To transfer wireless energy:

Wireless telephony is applicable to wirelessly energy transfer process, in this technology electrical energy is transmitted from a power source to an electrical load that does not have a built-in power source, without the use of interconnecting wires. There are two different fundamental methods for wireless energy transfer are as follow;

1. Far-field methods that involve beaming power/lasers,

2. Near-field using induction that involves radio or microwaves transmissions.

To support wireless medical technologies:

Latest wireless technologies of wireless telephony, such as mobile body area networks (MBAN), have the capability to monitor blood pressure, heart rate, oxygen level and body temperature. The MBAN works by sending low powered wireless signals to receivers that feed into nursing stations or monitoring sites. This technology helps with the intentional and unintentional risk of infection or disconnection that arises from wired connections.
