The aim of this report is to research wireless antennas and differences between them. Antennas are included 3 types: omnidirectional‚ semi-directional‚ and highly-directional. Any antenna has three fundamental properties: gain‚ directional and polarization. Omnidirectional Antennas. We can use this antenna in a: point-multipoint link‚ warehouse‚ hotspot‚ trade show‚ airport. The omnidirectional antennas transmit a signal in all directions‚ it is known dipole ("non-directional") antenna. The

7. How do local area networks (LANs) differ from metropolitan area network (MAN)? A local area network (LAN) is a group of microcomputers located in the same general area. It covers a clearly defined small area‚ such as an office‚ home network ‚one floor or work area‚ a single building‚ or a group of buildings. While a metropolitan area network (MAN) connects LANs and BNs located in different areas to each other and to WANs. MANs typically span between three and 30 miles. For example a large university
