- come out this yearTechnically, is a chip to be plugged into computers, printers, mobile phones, etc. Designed by taking the information normally carried by the cable, and transmitting it at a special frequency to a receiver Bluetooth chip which will then give information received to these mobile devices.
History come out this yearHistoryThe Bluetooth Special Interest Group (SIG) was founded by Ericsson, IBM, Intel, Nokia and Toshiba in February 1998 to develop as open specification for short-range wireless connectivity.
Usage come out this yearHome: Having multiple PCs and need for networks that are simple to install and maintainCommercially: Handhelds and other mobile devices
Some System requirements come out this year:- Universal framework to access information across a diverse set of devices- Should offer similar protection as in cables. There should not be any compromises on security- It should be simple, small and power efficient for easy mobile usage
Works with: Any laptop, handheld PC or PDA with a spare Type II PCMCIA slotOperating Systems: Windows XP, Windows 2000, Windows 98, Windows 95 or Windows CE
Two possible security modes for devices II PCMCIA slot:
Such a device would have access to all services for which the trust relationship has been set.
Such a device would have restricted access to services.
Three levels of security for services:
access granted to trusted devices
the remote device must be authenticated
The link must be changed to encrypted mode, before access to the service is possibleSecurity Implementation within the Architecture
Limited transport in 2.4 GHz band. Mbps for BlueTooth. Need higher rate for Local Area Networks. (sending graphics to be printed)
mutual perturbation (cross-talk) of corresponding office equipment within a same building
frequency hopping provides some level of security, confidentiality may be compromised via currently available decoder technology.
Bluetooth is WPAN (Wireless Personal Area Network) not LAN replacement. low cost, low profile, low power wireless link for convenience
BT not designed for large file nor fast transfer; for mobility and convenience
wireless devices always have security issues, but BT’s range is 10 meters need to be within this range to pick up transmission
Higher frequency 60GHz: a. free world wide b. less cross talk thus more confidentiality of transmitted information c. larger bandwidth than 2.4 GHz
60 GHz - Not Cost Effective (potentially higher cost of necessary adapters. Power drain and may be larger in size. BlueTooth designed to circumvent these issues. Cheap, low power, and convenient.
1MB/sec, 10 meters, 7 active devices b. less cross talk thus more confidentiality of transmitted information c. larger bandwidth than 2.4 GHz
can be used wherever you are – home, office or on the move. (PDA, mobile phone)
Cheap; various applications to drive the price down (electronics, telecoms, automotive and computing)
BT future revision may be as a high speed network solution
10 MB/sec, 50 meters, 10 active devices
wireless networking only
higher speed wireless networking solutionFuture :Is it already here? BluetoothvsAirport (802.11)
