Wireless mesh network
A wireless mesh network is a wireless network made up of radio nodes organized in a mesh topology. Each node forwards messages on behalf of the other nodes. Mesh networks can "self heal", automatically re-routing around a node that has lost power.
Wireless LAN
A wireless local area network (WLAN) links two or more devices over a short distance using a wireless distribution method, usually providing a connection through an access point for Internet access. The use of spread-spectrum or OFDM technologies may allow users to move around within a local coverage area, and s t i l l remain connected to the network.
What ’ s Wi-Fi?
A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication.
Mobile devices networks
GSM: The GSM network is divided into three major systems: the switching system, the base station system, and the operation and support system. The cell phone connects to the base system station which then connects to the operation and support station; it then connects to the switching station where the call is transferred to where it needs to go. GSM is the most common standard and is used for a majority of cell phones.
Wireless network refers to any type of computer
network that is not connected by cables of any kind.
What ’ s the wireless networks?
It is a method by which homes, telecommunications networks and enterprise installations avoid the costly process of introducing cables into building, or as a connection between various equipment locations.

Types of wireless networks
Wireless PAN Wireless LAN Wireless mesh network Wireless MAN Wireless WAN Mobile devices networks
Wireless PAN
WPAN interconnect devices within a relatively smal l area, that is generally within a person"s reach. For example, both Bluetooth radio and invisible in frare light provides a WPAN for interconnecting a headset to a laptop. ZigBee also supports WPAN appl i c a t i o n s . W i - F i PANs are becoming common-place (2010) as equipment designers start to integrate WiFi into a variety of consumer electronic devices. In "My WiFi" and Windows 7 "virtual Wi-Fi" cap-a b i l i t i have made Wi-Fi PANs simpler and easier to set up and configure.
Wireless MAN Wireless WAN
WMAN are a type of wireless network that connects several wireless LANs. WWAN are a type of wireless network that connects several wireless MANs. The wireless connections between access points are usually point to point microwave links using parabolic dishes on the 2.4 GHz band, rather than omnidirectional antennas used with smaller networks.
4G network on the BRTB1 ! !
If you make sure you cellphone or computer has wireles transmitters, you could make access to the 4G network on the BRTB1! You could watch a HD-movie or download music at the speed of 1.4MB/s or more . Is it amuzing?
How Wi-Fi works?
The process works in reverse, with the router receiving information from the Internet, translating it into a radio signal and sending it to the computer"s wireless adapter. They transmit at frequencies of 2.4 GHz or 5 GHz. This frequency is considerably higher than the frequencies used for cell phones, walkie-talkies and televisions. The highe frequency allows the signal to carry more data.
PCS :PCS is a radio band that can be used by mobile phones in North America and South Asia. Sprint happened to be the first service to set up a PCS.
D-AMPS : Digital Advanced Mobile Phone Service, an upgraded version of AMPS, is being phased out due to advancement in technology. The newer GSM networks are replacing the older system.
