Wireless communication involves the transmission of information over a distance without the aid of wires, cables and other electrical conductors. The distance distribution can also reach anywhere within a few meters (eg TV remote control) and the thousands of kilometers (eg radio communication). Some devices are typically used for wireless communication is a wireless phone, cell phone, GPS, computer parts wireless and satellite television.
Best Wireless Technology
The advantage of using wireless technology
- The communication system has become better so that they can deliver information more quickly to consumers.
- Professional workers can work and access the internet anywhere and anytime without having to carry around cables wherever they go. It helps them to be able to complete the job on time thus increasing productivity.
- Doctors, workers and others can be located in a remote area may contact the health center through wireless communication devices.
- The precarious situation can be overcome with the wireless communications technology. The region affected can be assisted and supported by the service alert through the help of wireless communications technology.
- Wireless networks are cheaper to install and maintain.
Disadvantages wireless technology
The development of wireless networks is allowing us to use personal devices anytime and anywhere. Wireless technology is already helping people in all aspects of their lives, but wireless technologies also pose much of a threat as well. For example, wireless technology threatens the security of many things in human life. It is easy for hackers to take the wireless signal is spread in the air. It is important to keep the wireless network so that information that we have not exploited by users who are not permitted.
Strong security protocols must be created to secure wireless signals such as WPA and WPA2. Another way to secure a wireless network is to install an interference suppression system. There are several types of wireless communication technologies, among others:
Infrared (IR) wireless communication
Wireless IR communication technology deliver data or information on the device or system via infrared radiation. Infrared is electromagnetic energy wavelengths over a red light. IR wireless used for short to medium distance communication and security control.
IR communications systems work normally operated in the mode line-of-sight, which means there are no obstacles between the transmitter (source) and receiver (destination). Infrared remote control is usually used in television and security systems.
Wireless WAN (wireless wide area network)
Best Wireless Technology Future
Wireless WAN is a wide area network is the coverage area of its widespread or mobile connected wirelessly to provide services on a large geographic area. WWAN services are especially intended for smart phones and other handheld devices sold by cellular service providers and their retail partners, but other mobile devices can also be used. In addition, some netbooks are available with WWAN card already installed in it, but if we have not installed netbook WWAN card, we can buy and install them yourself.
Unlike Wi-Fi card that can only be used in hotspot areas only, the device must be specifically determined WWAN for access services provided by the network provider. The Company will take care of the bill provide roaming access which involves a network of other providers.
Radio frequency
Radio frequency (RF) electromagnetic wave frequency is the vast stretches of about 3 kHz to 300 GHz, including frequencies used for communications or radar signals. RF usually refers to electrical rather than mechanical oscillations. To receive radio signals, we must use the antenna as well.
However, when the antenna can take thousands of radio signals, then we need to turn on the radio tuner or find a specific frequency. This is usually done through a resonator that is a circuit board or electrical conductor comprising a capacitor and inductor forming circuit turned. Resonator strengthen oscillations within a certain frequency band, but the resonator also reduces oscillations at frequencies outside the band.
