Now idea gather the Service Set Identifier (SSID) and Bluetooth Communications technology. Lets start………………
The Service Set Identiﬁer (SSID) is a 32-bit alphanumeric string that identiﬁes a WAP and all devices that connect to it. Because a wireless client device must provide the SSID in order to connect to the WAP, the SSID functions as a sort of password for the wireless network. However, because the WAP typically broadcasts the SSID in plain text, it does not provide any security. It is more realistic to think of the SSID as a network name that is applied to the grouping of the WAP and the devices currently connected to it. The administrator can accept a device’s default SSID or specify an SSID manually to more clearly identify the device.
Bluetooth is a wireless radio protocol that is used to communicate from one device to another in a small area, usually less than 30 feet. Bluetooth is commonly used to enable communication between small personal electronic devices, such as between a cellular phone and a wireless earpiece or between an electronic organizer and a personal computer.
Bluetooth Technical Speciﬁcations
Bluetooth uses the 2.4 GHz spectrum to communicate a 1 Mbps connection between two devices for both a 232 Kbps voice channel and a 768 Kbps data channel (technically, Bluetooth detects other devices in the 2.4 GHz spectrum and avoids the frequencies they use by “hopping” to an available frequency). Bluetooth 2.0 is a more improved version of Bluetooth, has a range up to 100 meters, offers faster data transfer speeds (up to 3 Mbps), and also uses less power to extend battery life. Bluetooth 2.0 is backwards-compatible with earlier versions of Bluetooth, but the connection between devices is governed by the slowest device; in other words, connecting a Bluetooth 1.2 device to a Bluetooth 2.0 device means the data transfer is at the rate of Bluetooth 1.2. Bluetooth 3.0 is available but not yet widely adopted, though it boasts speeds up to 24 Mbps.
