Bluetooth is used to send files such as songs,pictures etc it is a wireless technology standard for exchanging data over short distances .A master Bluetooth device can communicate with a maximum of seven devices Bluetooth is a standard wire-replacement communications protocol primarily designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. When any other device tries to establish a connection to the user's gadget, the user has to decide to allow it. Service-level security and device-level security work together to protect Bluetooth devices from unauthorized data transmission. Security methods include authorization and identification procedures that limit the use of Bluetooth services to the registered user and require that users make a  conscious decision to open a file or accept a data transfer. As long as these measures are enabled on the user's phone or other device, unauthorized access is unlikely. 

 Infrared Data Association ( is an industry driven interest group that was founded in 1993 by around 50 companies point infrared can be used at least a meter apart it has been implemented in portable devices such as mobile phones, laptops, cameras, printers, medical devices and many more. Main characteristics of this kind of optical wireless communication is physically secure data transfer. The frame size depends on the data rate mostly and varies between 64 Byte and 64 k Byte  Additionally bigger blocks of data can be transferred by sending multiple frames consecutively. 

GPRS Tunneling Protocol  is a group of IP-based communications protocols used to carry general packet radio service (GPRS) within networks it can be decomposed into separate protocols.

WI-Fi is a very common wireless technology . It is used to connect machines such as mobiles headsets ipads computers etc.  WI-Fi is like a wireless version of Internet. Wi-Fi is technically referred to as the 802.11 protocol. Over time, Wi-Fi has improved, giving rise to different variations of the protocol:802.11a This version operates at 54 Mbps.. The problem with it is distance; beyond 100 feet, you are out of the network.802.11b This version operates at 11 Mbps, but the distance of transmission is 300 feet, which is a considerable improvement over its predecessor. This version is used for public hotspots and small campus environments.802. 11g This version is relatively new and is considered as a high-speed replacement for 802.11b. It works at 54 Mbps, most wifi spots have passwords so people cant just connect to it


Microsoft Media Server (MMS), sends pictures to other devices a Microsoft proprietary network-streaming protocol, serves to transfer unicast data in Windows Media Services  If using Windows Media Player 11 and an RTSP attempt fails, or if using a previous version of Windows Media Player and MMS fails, a modified version of a HTTP over TCP connection will be attempted. This modified version is referred to by some third parties as MMSH, and by Microsoft as MS-WMSP The URI scheme "mms://" has also been proposed to be used for the unrelated Multimedia Messaging Service (MMS) protocol.For several years developers of the SDP Multimedia download-tool reverse-engineered the MMS protocol and published unofficial documentation for it. However, Microsoft finally released the protocol specification in February 2008 mms send straight to the person so nobody else will see it unless they show them .

 Short Message Service (SMS),is a delivery of text and numeric information for paging, messaging, and voice mails.  This standard includes Service Option 6 and Service Option 14 which support delivery of short messages  Mobile Station-Base Station Compatibility Standard for Dual- Mode Spread Spectrum Systems,  Support for 14.4 kbps Data Rate and PCS Interaction for Spread Spectrum Cellular Systems Personal Station- Base Station Compatibility Requirements for 1.8 to 2.0 GHz Code Division Multiple Access  Personal Communications Systems. A mobile station can obtain Short Message Service operating in either the analog or the spread spectrum mode when it conforms to this standard and any of the following standards: This standard does not address the quality or reliability of Short . all WiFi's  have incripted codes so it is impossible to hack into.
