A provider-independent address space (PI) is a block of IP addresses assigned by a regional Internet registry (RIR) directly to an end-user organization. [1] The user must contract [2] with a local Internet registry (LIR) through an Internet service provider to obtain routing of the address block within the Internet.
A wireless Internet service provider (WISP) is an Internet service provider with a network based on wireless networking. Technology may include commonplace Wi-Fi wireless mesh networking , or proprietary equipment designed to operate over open 900 MHz , 2.4 GHz , 4.9, 5, 24, and 60 GHz bands or licensed frequencies in the UHF band (including ...
The result was the first (FCC licensed) point-to-point microwave radio capable of delivering 10 Mbps Ethernet, full-duplex, between local and remote networks up to 4.3 miles apart. Distance limitation had more to do with 802.3 Ethernet latency than microwave range.
This can be a local WAN connection. Cell phones communicating with a single cell tower constitute a local subnetwork; the connection between the cell tower and the rest of the world begins with a backhaul link to the core of the internet service provider's network (via a point of presence). A backhaul may include wired, fiber optic and wireless ...
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, [1] [2] [3] and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and sharing network devices, such as printers.
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.

Both IEEE 802.11, which includes Wi-Fi, and IEEE 802.16, which includes WiMAX, define Peer-to-Peer (P2P) and wireless ad hoc networks, where an end user communicates to users or servers on another Local Area Network (LAN) using its access point or base station. However, 802.11 supports also direct ad hoc or peer to peer networking between end ...
