Wireless Networking Point to Point connectivity :-The point-to-point wireless topology (also called P2P) is the simplest network architecture you can set up in order to connect two locations using a wireless radio link.Point-to-point wireless links can go from a short-range link connecting two locations just a few hundreds meters apart to a long range point-to-point wireless link that connects two locations tens of miles away from each other. In a point to-point-wireless link, distance is affected by the height of each Ethernet radio device, the frequency used, the power level, and environmental interference.Point-to-point wireless links are usually deployed between two locations that are in clear line of sight (LOS) with each other in other to maximise the performance of the wireless link. For point-to-point wireless links working in the license free 5 GHz band (for example in the 5.8 GHz or 5.4 GHz license-free bands) or in the 4.9 GHz public safety band we suggest to deploy the link in clear ling of sight (LOS) because, above 2.4 GHz, line of sight (LOS) operations provide a much more reliable wireless link.Wi - Fi Router Configaration :-Netgare, D-Link, TP-Link, Cisco routers.Wi-Fi is a term for certain types of wireless local area networks (WLAN) that use specifications in the 802.11 family. Products that pass the Wi-Fi Alliance tests for interoperability, security and application-Unless adequately protected, a Wi-Fi network can be susceptible to access by unauthorized users who use the access as a free Internet connection. The activity of locating and exploiting security-exposed wireless LANs is called war driving. An identifying iconography, called war chalking, has evolved. Any entity that has a wireless LAN should use security safeguards such as the Wired Equivalent Privacy (WEP) encryption standard, the more recent Wi-Fi Protected Access (WPA), Internet Protocol Security (IPsec), or a virtual private network (VPN).
