Wireless computer headset is used in the telecommunication systems to transfer information without the use of wires. It can be used both for long or short distant communication.

They also use electromagnetic waves to carry signal of the whole communication path.

Below are some of the most commonly examples which can be used in wireless computer headset:-

• LMR and SMR which are used by business, industrial and public safety people.
• Consumer two way radios
• Marine VHF radios
• Cellular telephone for both portable and mobile computer headset.
• GPS which is normally used by motor vehicle drivers, aircraft pilots and ship captain to guild them on the location there are in.
• Computer accessories such as keyboard, mouse and printers.
• Cordless telephones
• Satellite television
• Wireless gaming

All this examples are used in wireless computer headset within seconds while using the Wifi devices by connecting to the laptop which is easy to carry from one point to another. This technology has justified the use of wireless computer headset such as:-

• Distance of cabling the normal cables.
• To avoid structures such as EMI or RFI
• It provides communication incase of normal network blackouts.
• To provide temporary workstations
• To connect mobile or networks remotely

Most people have been confusing the term wireless and cordless. Cordless are cables devices that operate from a power socket from the main power supply.

A wireless operation was first invented by Jagadish Chandra Bose with the first detection device, electromagnetic wave and biophysics in the field.

Eight years later David E Hughes introduced morse code with a transmission called clockwork transmitter and in 1885 T.A. Edison invented a magnet vibrator which was used to signor the Lehigh valley railway and in 1888 he invented a wireless patent.

In the same year Heinrich Rudolf Hertz introduced the theory of electromagnetic wave which had early on been researched by James Clerk Maxwell and Michael Faraday. Rudolf demonstrated that electromagnetic waves could be transmitted through straight lines and were able to receive.

Later on his experiment was borrowed by Hertz with the practical application of the wireless communication with the remote control technology been improved by Nikola Tesla.

Wireless computer headsets have become so popular in today’s world as it is less expensive. This new technology has found customers been charged a very minimum service charge and others been charged for free.

While the technical term for the wireless network can be used to refer to any type of network is wireless, the term is most commonly used to refer to a telecommunications network whose interconnections between nodes is performed without the use of cables, such as a computer network (which is a type of communications network). The wireless telecommunications networks generally implemented with some form of remote transmission system information.

Applications of wireless technology

1) Security System

Control 2) Television remote

3) Voip

5) Wi-Fi

Benefits of wireless technology

Wireless LANs offer the following productivity, convenience and cost advantages through wired networks:

• Mobility – Wireless LAN Wireless Systems can provide users with access to information real time anywhere in your organization. This mobility includes productivity and service opportunities not possible with wired networks.
• Installing high speed – Installing a wireless network may be fast and easy and can eliminate the need to pull cable through walls and ceilings.

• A minimum cost-of-Ownership – While the initial investment required for wireless LAN hardware can be greater than the cost of wired LAN hardware, installation costs in general and life cycle costs can be significantly lower. The long-term benefits outweigh costs in dynamic environments requiring frequent moves and changes.

• Flexibility: Wireless LAN systems can be configured in a variety of topologies to meet the needs of specific applications and installations. Configurations are easily changed and range from peer-to-peer suitable for a small number of users to full infrastructure networks of thousands of users that enable roaming over a wide area.

Common examples of wireless equipment in use today include:

· Professional LMR (Land Mobile Radio) and SMR (Specialized Mobile Radio) typically used by businesses, industrial and public safety entities

· Consumer Two Way Radio and FRS (Family Radio Service), GMRS (General Mobile Radio Service) and Citizens Band (CB) Radios

• The Amateur Radio Service

Professional and consumer · VHF radios marine

• Phones phones and pagers: provide connectivity for portable and mobile applications, both personal and business.

· Global Positioning System (GPS): allows drivers, captains of boats and ships, and pilots of aircraft to determine or find your location at any place on earth.

· Wireless Peripherals: Wireless mouse is a common example, keyboards and printers can also be linked to a computer wirelessly.

· Wireless phone devices: these devices are limited range, not to be confused with mobile phones.

· Satellite television: allows viewers in almost any location to select from hundreds of channels.
