Understanding Wireless Lan Networking And Long Range Wireless Lan Communication

Understanding Wireless Lan Networking and​ Long-range Wireless Lan Communication
Understanding wireless and​ wireless LAN networking enable you to​ properly plan and​ design the​ effective deployment of​ wireless networks be it​ home-networking or​ using outdoor long-range WLAN for​ rural internet connectivity.
Wireless networking allows computers and​ peripherals to​ communicate using radio frequency (RF) transmissions rather than over conventional network cabling .​
Using wireless Ethernet adaptors, any device capable of​ being used on a​ regular computer network can be accessed over a​ wireless connection for​ task ranging from file and​ printer sharing to​ multimedia and​ internet access.
Wireless Ethernet Technology is​ outlined by a​ set of​ standards called IEEE 802.11 .​
Although other wireless technologies and​ protocols exist, the​ term wireless is​ generally used in​ reference to​ the​ IEEE 802.11 standards.
The communication protocols for​ wireless networking are defined by the​ Institute of​ Electrical Engineers (IEEE) 802.11 standard, which incorporates the​ 802.11a, 802.11b and​ 802.11g protocols (although other standards are in​ progress) .​
The most widely used of​ these is​ 802.11b (Wireless-B), which is​ more reliable than the​ faster 802.11a (Wireless-A) standard, and​ is​ more cost-effective to​ produce and​ operate as​ well .​
Wireless-G or​ 802.11g, is​ a​ newer protocol that is​ becoming more widely adopted by vendors as​ it​ is​ capable of​ speeds up to​ 54Mbps rather than the​ 11Mbps of​ 802.11b devices.
It is​ no longer rare to​ find devices that support all three standards, but generally, Wireless-G is​ designed to​ be backwards compatible with Wireless-B devices .​
Thus Wireless-B and​ Wireless-A devices will not work with each other, and​ neither are they compatible with Wireless-G devices.
Some manufacturers offer models with dual-band (Wireless a​ & G/B) auto-switch mode for​ greater communication flexibility .​
Network planners can plan their network deployment by using a​ combination of​ Wireless-B,G or​ A.
Wireless 802.11 standard utilizes the​ license-free radio frequency bands around the​ 2.4GHz and/or 5GHz ranges .​
The 802.11b and​ 802.11g protocols use the​ 2.4GHz band whereas 802.11a uses the​ 5GHz band .​
Wireless-B is​ by far the​ most popular standard, with the​ newer Wireless-G (802.11g) and​ Wireless-A (802.11a) closing in​ fast.
Wi-FI or​ Wireless Fidelity is​ a​ certification program established by the​ Wi-Fi Alliance to​ ensure interoperability of​ wireless devices .​
Originally, the​ term Wi-Fi was intended to​ be interchangeable with 802.11b, but more recently it​ has broadened to​ cover any 802.11 network.
WLAN or​ Wireless Local Area Network, is​ a​ computer network –or part thereof- that incorporates wireless devices .​
In a​ WLAN network, a​ conventional LAN set-up can be extended to​ include wireless devices using an​ access point .​
Although wireless networks can be completely independent of​ conventional network, WLAN usually forms part of​ an​ existing wired network.
Wireless Transmission ranges vary greatly and​ lowering the​ bandwidth will increase the​ coverage area, a​ standard 802.11b or​ 802.11g device will typically have a​ range of​ about 30m indoor and​ up to​ 120m line-of-sight outdoors .​
The main reason for​ the​ variance between indoors and​ line-of-sight coverage is​ that walls and​ other objects do impede the​ wireless signal .​
Because wireless transmissions are actually low frequency radio waves, they will pass through walls and​ other solid matter relatively easy .​
As distance increases, the​ throughput decreases .​
This is​ because lower signal strength result in​ dropped packets and​ result in​ a​ general decrease in​ network efficiency.
Understanding the​ technology in​ wireless and​ wireless LAN/WAN networking allows the​ planner the​ flexibility of​ using wired and​ wireless networks .​
There are areas that wired networks can not go owing to​ distance, terrain or​ topography thus if​ the​ planner has knowledge on wireless LAN networking, the​ simpler, faster and​ easy it​ is​ to​ deploy an​ effective wireless network.
Understanding how wireless LAN works will also help you plan deployment of​ a​ rural wireless internet access service .​
Wireless LAN is​ a​ very cost-effective solution for​ much needed internet connectivity requirements in​ far, remote villages .​
WISP is​ a​ good and​ potential business in​ remote areas.
Either you use commercial off-the-shelf WLAN gadget, tweak and​ improve its performance by using higher-gain outdoor antenna or​ buy a​ true-outdoor long-range Wireless LAN .​
For assured network performance, service-quality and​ less network downtime, we recommend using the​ latter.
The goal is​ to​ reach people yearning to​ start their own home-based business even in​ remote regions thru cost-effective internet business and​ long-range wireless communication solutions.
