It is primarily used in smart homes particularly for control, monitoring and status reading for household appliances having physical range of 100 meters. It operates in ISM band and is developed for low bandwidth data communication applications. This technology, due to its interoperability … Read more

What is Zigbee?

Zigbee is a wireless technology based on IEEE 802.15.4 standard which very well suits the unique needs of low cost, low power wireless IoT networks. It was created by the ZigBee Alliance which comprises of technology partners like Philips, Motorola, Intel and HP. It operates in the unlicensed band including 2.4 GHz, 900 MHz and … Read more

What is Wi-Fi?

Wi-Fi is the wireless networking technology that connects the device with the Internet. Rather than using wires it uses radio waves to transmit information. Wi-Fi stands for Wireless Fidelity. When an antenna receives this radio wave, an electromagnetic field is created which can travel through space. It is based on IEEE 802.11 family of standards. … Read more

Wired Communication Protocols

Wired Communication implies transmission of data from the transmitter to the receiver end point over a wired physical medium. Examples of wired communication includes Telephone lines and Television transmission system. It may use devices like ethernet, RS-232 or RS-485 cables or Universal Serial Bus (USB) for data transmission. It is advantageous to use Wired Communication … Read more
