Wireless communication has captured the attention of media and the imagination of the public. Wireless communication is one of the fastest growing segments in the communication industry and also offers long-range communications that are not possible with the usage of wires. The recent developments in the wireless technologies have given birth to various new technologies like ZigBee, RFID etc.
This course covers a complete note on wireless communication which involves Point-to- point links, IEEE 802.11, OSI model, Antennas, WLAN & Medium Access Control.
After completion of this course, students will know completely about wireless communication and also about some of the new technologies like Wireless HART, ZigBee and RFID.
