Alpine WiFi

WiFi networks follow the 802.11 standard developed by IEEE (Institute of Electrical and Electronics Engineers) and approved in 1997, which is widely accepted by the international community. At the time of drafting the standard WiFi networks operate using the 2.4GHz frequency, which is license-free, and allowed a maximum bandwidth between 1 and 2Mbps. More recently, in 1999, approved the 802.11b and 802.11a standards, using frequencies of 2.4 GHz and 5 GHz and can achieve 11Mbps to 54Mbps, respectively.

Currently the most widely used standard is 802.11g which has the same specifications of the 802.11b standard, but offers speeds up to 54Mbps. There are several promising areas of standardization such as 802.11n is in final approval and will have their bandwidth reaching up to 104Mbps operating in the 2.4 GHz (free) and 5GHz (licensed). Some companies including Cisco, released a proposal for the IEEE 802.11s mesh networking specific you want to standardize the routing protocols and management of a mesh network. As defined by Professor Celio Vinicius Neves Albuquerque (UFF) Mesh networks are “wireless mesh networks that interconnect self-configuring a set of fixed nodes are able to route packets between them.”

Usually the nodes and network routers use technology WiMesh 802.11 Ad-hoc mode, where the access nodes to communicate without the need for a central AP controlling all communication, creating a mesh asim wireless data with low cost of deployment not due to the need for prior establishment of an infrastructure. Wireless networks increasingly have had an increasing involvement in our lives and many technologies have been created to explore this. Expected to have achieved the goal of making it easier to understand the operation of networks WiMesh, although not the intention of this material as a guide, but dilute, for academics and others associated with deploying and maintaining networks, the quest for technology that best fits your needs.
