Low-Power Wireless Area Network (LPWAN) and Low-Power Wireless Personal Area Networks (LoWPAN) Overview
A personal area network (PAN) is the backbone of a personal computer and electronics device network that encompasses a personal workspace. A wide-area network (WAN) is a wireless telecommunication wide area network that is designed to allow for long-range communication among connected devices. A wireless PAN (WPAN) is just a PAN that uses wireless data connections to the myriad of potential...
Yagi Antennas- Front to Back Ratio, Gain vs # of Elements, and Element Spacing Explained
A Yagi-Uda Antenna (Yagi Antenna), named after the co-inventors Hidetsugu Yagi and Shintaro Uda, is a direction antenna with a single driven dipole section with a series of parasitic elements (directors) that re-radiate energy from the main dipole thus manipulating the antenna pattern. The parasitic elements of a Yagi antenna are within the near field of the main dipole, and hence significantly...
