WAP internet through computer data




WAP internet through computer data
The Low Income Weatherization Assistance Program (WAP) provides eligible households with full-scale home energy conservation services.

The program is administered by a network of local agencies, in many areas the same agency that administers the Low Income Home Energy Assistance Program (LIHEAP or Fuel Assistance) program. See the “How to Apply” section below to find the local weatherization agency.

Eligible Applicants

Households that are eligible for the Low Income Home Energy Assistance Program (LIHEAP or Fuel Assistance) are eligible for weatherization services. Eligibility is based on a maximum gross annual income not to exceed 60% of the Estimated State Median Income. Priority of service is given to those households with elderly, disabled, children (6 and under), LIHEAP high-energy users, and Native Americans. Homeowners and tenants with their landlord's permission are eligible.

A typical corporate use involves attaching several WAPs to a wired network and then providing wireless access to the office LAN. Within the range of the WAPs, the wireless end user has a full network connection with the benefit of mobility. In this instance, the WAP functions as a gateway for clients to access the wired network.

A Hot Spot is a common public application of WAPs, where wireless clients can connect to the Internet without regard for the particular networks to which they have attached for the moment. The concept has become common in large cities, where a combination of coffeehouses, libraries, as well as privately owned open access points, allow clients to stay more or less continuously connected to the Internet, while moving around. A collection of connected Hot Spots can be referred to as a lily-pad network.

The majority of WAPs are used in Home wireless networks. Home networks generally have only one WAP to connect all the computers in a home. Most are wireless routers, meaning converged devices that include a WAP, router, and often an ethernet switch in the same device. Many also converge a broadband modem. In places where most homes have their own WAP within range of the neighbors’ WAP, it’s possible for technically savvy people to turn off their encryption and set up a wireless community network, creating an intra-city communication network without the need of wired networks.

A WAP may also act as the network’s arbitrator, negotiating when each nearby client device can transmit. However, the vast majority of currently installed IEEE 802.11 networks do not implement this, using a distributed pseudo-random algorithm called CSMA/CD instead.
