This communication can be between two portable devices or between a portable device and a fixed device. Infrared Communication. Disadvantages of Infrared . Still, I have answered 2 questions. Isolation of signal to the room—important if privacy is an issue. disadvantages - radiation can ionize and damage cells and is very expensive to use. The transmission data rate is low. Microwave spectrum is divided into a different channel as per application. Infrared waves cannot penetrate the walls. The advantages for this method is it able to engender a strongest signal compare with mutual capacitance, but the disadvantages is it can't accurately resolve more than one finger, as a result in "ghosting", or mislay position catching. The propagation of light waves in this band can be used for a communication system (for transmission and reception) of data. They are extremely reliable. • IR devices are less costly. Interconnection of systems, people or things with the help of a communication media can be referred as network.The type of communication in which use electromagnetic waves as communication media for transmitting and receiving data or voice is called wireless communication.The electromagnetic spectrum is divided into well-defined channel for data transmission. Another advantage of infrared communication is massive bandwidth which is available for use, but has not been exploited to its full extent. Unlike radio-based communication, an IrDA transmitter needs to be aligned with an IrDA receiver. They can be blocked by anything and everything we can imagine ranging from rain droplets to fog and dust particles. Their main disadvantage is that infrared is quite easily shielded. Spectrum sensing is used to detect the (unlicensed) the unused (licensed) frequency bands. (Planarembeddred, 2010) Infrared This can generate several interferences with IR transmission. Infrared waves at high force can harm eyes. Satellite Communication is one of the most impressive spin-off from space programs, and made a major contribution to the international communication. They are very fast. Advantages and disadvantages 7 7. In a low-cost wireless infrared system, it is extremely difficult to collect appreciable signal power in a single electromagnetic mode. It is not feasible for intruder to come in between and hack the data. This represents that it can easily include it within a room. These waves cannot be used for longer distances. There is some kind of IR communication between the ir remote and the receiver devices who receive the ir signal. The applications of infrared transmissions are as .
