Radio Transmission
Wireless LAN devices use electromagnetic waves within a broad, unlicensed range of the radio spectrum to transmit and receive radio signals. When a wireless access point is present, it becomes a base station for the Wireless LAN nodes in its broadcast range. Wireless LAN nodes transmit digital data using FM (frequency modulation) radio signals. Wireless LAN devices generate a carrier wave and modulate this signal using various techniques. In this way, digital data can then be superimposed onto the carrier signal. This radio signal carries data to Wireless LAN devices within range of the transmitting device. The antennae of Wireless LAN devices listen for and receive the signal.
Range
Range should not be a problem in most homes or small offices. If you experience low or no signal strength in some areas, consider positioning the device in a location between the Wireless LAN devices maintaining a roughly equal
SSID
Wireless networks use an SSID (Service Set Identifier) to allow wireless devices to roam within the range of the network. Wireless devices that wish to communicate with each other must use the same SSID. Several Wireless Broadband Routers or access points can be set up using the same SSID so that wireless stations can move from one location to another without losing connection to the wireless network.
The Wireless Broadband Router operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast area. It will allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. The Conceptronic C300BRS4 broadcasts its SSID so that any wireless station in range can learn the SSID and ask permission to associate with it. Many wireless adapters are able to survey or scan the wireless environment for access points. An access point in Infrastructure mode allows wireless devices to survey that network and select an access point with which to associate.
