Knowing the difference between wireless and wireless networks will help you plan and design the efficient implementation of networks using wireless technology, whether it at home or with outdoor long-range WiFi for internet connectivity in rural areas Wi-Fi Site survey.
Wireless networking permits peripherals and computers to communicate via radio frequency (RF) transmissions instead of using traditional network cabling. With wireless Ethernet adapters, any device that is able to be connected to a computer network is able to be accessed via a wireless connection to perform tasks ranging from sharing printers and files to accessing internet and multimedia.
wireless Ethernet Technology is defined by an array of standards referred to as IEEE 802.11. While other wireless technologies and protocols are available but the term “wireless” is usually used to refer specifically to the IEEE 802.11 standards.
The protocols for wireless communication networks are defined in the Institute of Electrical Engineers (IEEE) 802.11 standard that incorporates standards such as the 802.11a, 802.11b and 802.11g protocols (although other standards are also in development). The most popular of them are 802.11b (Wireless-B) which offers greater reliability than more robust 802.11a (Wireless-A) standards and is cheaper to manufacture and run in addition. Wireless-G, also known as 802.11g is a brand new protocol that is now being widely used by manufacturers as it has speeds of up to 54Mbps, instead of the 11Mbps offered by 802.11b devices.
It’s not uncommon to discover devices that support three different standards, however generally, Wireless G is designed to be backward compatible with Wireless-B devices. Therefore, Wireless-B and Wireless-A devices are not compatible together nor are they compatible with Wireless-G devices.
Certain manufacturers have models that come that come with dual-band (Wireless A and G/B) auto-switch modes to provide greater connectivity flexibility. Network planners can design their network’s expansion using a combination of Wireless B, G or A.
The wireless 802.11 standard uses the licensed radio frequency bands that are within the 2.4GHz or 5GHz ranges. Its 802.11b as well as 802.11g protocols operate on the 2.4GHz band, whereas 802.11a utilizes bands 5GHz. Wireless-B is the most used standard and the latest wireless-g (802.11g) along with Wireless-A (802.11a) getting closer to.
Wi-Fi or Wireless Fidelity is a certification program that was created through the Wi-Fi Alliance to ensure interoperability of wireless devices. In the beginning, the term Wi-Fi was designed to interchange with 802.11b however, more recently it has been expanded to encompass all 802.11 network.
WLAN (also known as Wireless Local Area Network, is a network of computers – or part of it that includes wireless devices. In the case of a WLAN system, the traditional LAN setup can be expanded in order to incorporate wireless devices by using the access point. While wireless networks are entirely independent of traditional networks, WLAN usually forms part of a wired network.
Wireless transmission ranges differ greatly and by reducing the bandwidth, you can enhance the coverage, the standard 802.11b and 802.11g device typically has an area of around 30m indoor and as high as 120m line-of-sight outdoor. The reason behind the difference between indoors and line-of sight coverage is that walls and other obstacles hinder an antenna’s wireless signals. Since wireless transmissions are radio waves with low frequencies and are not acoustic, they can travel through solid objects fairly easily. As distance increases, efficiency of the transmission diminishes. This is due to reduced signal strength results in lost packets and in a decrease in the effectiveness of networks.
Understanding the technology behind wireless and wireless networks provides the planner with the freedom to utilize both wired and wireless networks. There are some areas where wired networks aren’t able to go due to topography, terrain or distance so if the planner is equipped with the knowledge of wireless LAN networks and wireless LAN networking, the more simple, speedier and more simple it is to establish an efficient wireless network.
Knowing the way wireless LAN functions can aid in planning the deployment of an rural wireless internet access service. Wireless LAN is a affordable solution to the internet connectivity in extremely rural villages. WISP is a great and viable option for businesses in remote regions.
If you are using a the commercial “off-the-shelf” WLAN gadget, alter and improve its performance using a higher-gain outdoor antennas or an outdoor large-range Wireless LAN. To ensure high-quality network performance, reliable service and lower network downtime we recommend the latter.
