Bluetooth technologies replace cable technology. For instance, Bluetooth technology allows devices such as PC, MP3 players, and mobile phones and headsets to connect with one another. Unlike infrared, Bluetooth connect with other Bluetooth enable devices without requiring line-of-sight positioning thereby modifying wireless local area network and however, noted for its small size range of connection and low cost (BlueTomorrow.com). Bluetooth version ranges from v1.1 through v3.0 + HS. Bluetooth versions 1.1 were invented to ratified IEEE Standard 802.15.1. It offers many error correction found in 1.0B specifications and provide non-encrypted channel. After Bluetooth V1.1 came V1.2 with faster connection and discovery. It also supports higher transmission speed with extended synchronous connections that provide and support voice quality of audio links as well as enabling retransmission of corrupted packets. Furthermore, Bluetooth v1.2 also has Host Controller Interface (HCI) that enables individual to configure and modify the connection. Bluetooth version 2.0 +EDR provide faster data transfer of about 3 megabits per second. Besides that, it also uses Gaussian Frequency Shift Keying (GFSK) and Phase Shift Keying (PSK) combine to correct both positive and negative frequency. Nevertheless, the invention of Bluetooth version 2.1 + EDR was to enhance the secure simple pairing of v2.1 + EDR. In April 2009, Bluetooth version 3.0 +HS were adopted by the Bluetooth Special
