Best Information on Wireless Access Point
Before the advent of wireless networks, establishing a computer network usually required a few connections via cables through walls and ceilings of the premises in order to enable network access to all network-enabled devices within the same building. But with Wireless Access Point, minimal cables (or no cables at all) are needed by a network user to add devices to the wireless network and send and receive data using radio frequencies. The standards and frequencies that govern WAP are defined by IEEE. One of the more popular and currently adopted largely for wireless networking is the IEEE 802.11 standard.
Accessing a device on a WAP is limited to a certain range with in which the wireless end user has a full network connection with the added advantage of mobility. The actual range of a WAP can vary on variables such as indoor or outdoor placement, height above ground, obstructions in transmitted signals and nearby electronic devices that might cause interference in transmission of the signals. The range also depends on the type of antenna, weather, operation frequency and output power.
An alternate to an access point is an ad-hoc network that permits the exchange of data directly between devices and workstations without the need of a middle-man as in the case of WAP, resulting in a more useful bandwidth. However WAP provides the benefit of better range, security, power efficiency, service quality and roaming. A WAP also has the ability to act as a network arbitrator. Though not adopted by a majority, it allows monitoring the status of each devices and checking if it is ready for data transmission.
As opposed to wired networks that ensure a secure network and trusting all users on the local network, a wireless network can be utilized by anyone outside the premises. The most common solution to this issue is by adopting encryption. With the special security considerations in wireless access, WAPs come with in-built encryption that has evolved over time. The first generation encryption scheme WEP was easily cracked. The second and third generation schemes WPA and WPA2 are however secure enough if used in combination with a strong password.
With the ability of wireless devices to quickly switch from one frequency to another, a better reception on a different frequency can be achieved in cases where interlinked WAPs operate on different frequencies depending on the frequency bands allowed for wireless networking in different areas. However the limited frequency spectrum legally available for wireless networking can cause problems in densely populated areas where multiple WAPs are installed amid tall buildings. In such cases, an overlap can surely cause interference in signal transmission.
For a home-based network however, only one WAP suffices to connect all the computers within the premises. Most of these devices are wireless routers that bundles together a WAP, Ethernet router and often a switch. Using the encryption settings the user can enable or disable network access to neighbors giving other users a chance to either limit access just to them or create a community based (or a large one) intra-city wireless communication network. You can have a lot more information from the internet using various websites and other information can be taken from the books as well.
