A two way radio employs various technologies to send and receive data. These technologies have been se developed that they make the use of this type of a radio very easy. Also with every technology, different types of features are incorporated within the radio so that it meets the needs of the customers.
The first two way radios employed a conventional technology in which operated on fixed channels. The use of conventional technology allows the use of only a single channel at a time even if the radio can operate on multiple channels Trizetto login . When radios are made using this technology, they are provided a scan feature so that the user can scan for and find the particular channel that one wants to listen to or use for the transmission of data. The provision of this feature prevents the user from using the channel selector that takes a lot of time to locate a particular channel.
Another technology used for two way radios is the trunked technology. In this technology, the radio picks up a frequency by itself. In this type of technology, the radio channels work according to a protocol to ensure that the assignment of channels takes place automatically. In this type of a radio system, a control channel is used by the protocol so as to control the allocation of frequencies to the radio.
Simplex technology is yet another technology that is used for two way radios. In this a single channel is used by the radios to send and receive data. Radios with this technology are the most common ones used for the purpose of communication. These types of radios are the most reliable ones for short distance transmission of data. The duplex technology when used for two way radios makes available two different channels, one for sending data and the other for receiving data. The use of two separate channels ensures that the data or signals do not interfere with each other. The duplex technology can be used in two ways in a two way radio. The first is the half duplex technology in which a radio can either send or receive signals at any given time. The second one is the full duplex technology in which the radios can send and receive signals simultaneously. This technology results in faster transmission of data.
Push to talk technology has also been used in these types of radios recently. In these radios, a button has to be pushed to start the transmission of data. These are popularly used in different types of vehicles.
Are you aware of IPS Panel Technology? IPS (in-plane switching) technology is the best type of Panel Technology available today in the market for the manufacturing of LCD. When you buy a LCD monitor you never know what type of panel technology has been used in that monitor because the specification list does not mention the type of panel used in that LCD by the manufacturing company. It’s not the price that matters while you buy the LCD monitor, you should know about the benefits of the panel type in that particular brand of LCD before you buy it.
The Thin Film Transistor (TFT) technology is widely used by the manufacturers of LCD monitors which improves the quality of the image. IPS is the nickname of this TFT technology. The specifications and details of IPS Panel Technology are considered best for high accuracy in colour, its quality image and wide viewing angles. Various types of panels are available in the market at present and the most advanced being IPS but at a price. But who would not want a wide angle view which is an absolute treat after TN matrices and not to mention the high colour reproduction. The IPS (In Plane Switching) was developed by one of the most famous companies of Japan in 1996 to solve the problems of TN-matrices. IPS is now-a-days widely used technology by the manufacturers of LCD monitors other than the technologies like TN Film, MVA and PVA. The other panels may be popular within some users though they are inexpensive. But if you compare the IPS panel technology with other panels, you will find the colour reproduction and viewing angle more advantageous. The response time is excellent which makes them ideal for fast gaming. Used in 22″ monitor which is a size popular among consumers.
Being the excellent panel technology S-IPS/H-IPS panels are also expensive but they offer excellent picture reproduction and suitable for graphic work, web browsing and also other applications. You will find IPS technology used in panel sizes; in monitors, size ranging from 20 to 30 inches and in LCD monitors from17 to 52 inches. Up to 178 degree of wide viewing angle and reasonably okay response time are some of the few advantages it has to offer. The lower contrast level that IPS has does not give dark blacks as in the case of VA based panel technology and the pixel response is slower than TN panels but in the Super-IPS (S-IPS), the pixel response comes improved. The VA panel technology which has higher contrast levels gives darkest blacks and due to its disadvantage of colour shift, the details are lost when viewing the darker areas directly. The viewing angles are good but IPS is the best where the viewing angles are concerned
