How can I choose the best WLAN system?

and LAN is a network of local area - a collection of network devices, including at least one computer that is connected to communicate with each other. WAN is a network of a wide area, a LAN-like system, but on a larger scale, it may include multi-building devices or campus. WLAN - must not be confused with WAN - is a wireless network of local area, which is often called wireless rope . It is more of a LAN with at least one connection, which is wireless than cable. The WLAN system is a WLAN creation method and there are a few to choose. Both names indicate that this type of LAN is not in communication with any type of access point (AP), basic stations that have connections from the local network to the Internet. Another name for this type of WLAN system is the peer-to-peer mode . It can be created using a device with a WLANS PC card or with WLAN dongles.

WLAN system can also include AP, either as independentthe summer of the device or in the router. Any AP and its connected devices are called a set of basic services (BSS), which clarifies the abbreviation IBSS used for the AD HOC WLAN system. If there are two or more basic sets of services in the same subnet - the physical or logical distribution of WLAN - then an extended set of services (ESS) was created. Regardless of whether it is a BSS or ESS, this type of WLAN system is called the infrastructure mode . Therefore, when choosing the best WLAN system, you have to decide whether you need BSS, ESS or IBSS.

Another important point of view is the version or version of the 802.11 standard - the WiFi Standard set by the Institute of Electrical and Electronic Engineers (IEEE) -. The most common option is 802.11b, 802.11g and 802.11n. The choice depends on the standards of the WLAN system used and the consider if the components could be connected, for example, by the Ethernet cable, for example, than wirelessly. It is also possible to obtain dual bands that run at 2.4 GHz (Gigahertz) and 5 GHz and handle new and older devices.
