Low maintenance and installation cost compared to wired networks.Information (data, videos, etc.) is transferred quickly and faster.Wireless network systems are easy to set up, cheaper to install and also maintain.The Radio Frequency Identification (RFID)Īdvantages and disadvantages of wireless technologies.The Mobile Telephone System (Cellular Communication).There are so many wireless technologies now, and there’s a possibility of more in the future as technology advances and the needs of humans evolve. The receiver undoes what the transmitter did, and that’s why the receiver path has the demultiplexing, demodulation, channel decoding, decryption, and source decoding. It’s work is to reproduce the source information signal after receiving it from channel. It’s the medium of transmitting information signals from the sender (transmitter) to the recipient (receiver).

It’s then multiplexed and sent to the channel. The Encoder minimizes faults in the information like noise to get a modulated signal. The info is then encrypted by an Encryption standard then transferred to an Encoder. It has an encoder that receives information from the source and converts it into a readable signal. What are the main elements of a wireless communication system?Ī basic Wireless Communication System has 3 main elements: They interconnect compatible devices like phones, pcs, Bluetooth beacons near a central location.Ĭomes as a result of mobile phone signals provided by cellular service providers. They are short-range networks (usually a 30ft range) utilizing Bluetooth technology. The Wireless Personal Area Network (WPAN).They use radio waves, but the mother network uses wires but transmits to one or several wireless access points where a wireless user can connect to the wired network. The Wireless Wide Area Networks (WWAN).It’s a way of transferring information from point A to B (or between two or more points) without using any electrical conductor or physical medium. This shows how wireless communications systems have become an integral part of human’s day-to-day lives. Services like TV, Radio, cellular telephone, and live conferencing are made possible by wireless technologies. With wireless technologies, people can share data, voice, images, and even videos in a snap. Therefore, there’s a need for internet, multimedia, and most crucial, wireless communication networks. Apparently, the world is a global village, and people need to communicate, participate in projects and events virtually, and execute tasks remotely.
