Bluetooth is a wireless technology standard for exchanging data over short distances. It was originally conceived as a cable replacement and can be used for data transfer, wireless audio, etc. Bluetooth operates in the 2.4 GHz spectrum and has an effective range of about 10 meters. It works by establishing short-range radio links called piconets that allow devices to connect and exchange information securely in an ad-hoc manner. The technology has grown in popularity and future versions aim to improve capabilities such as speed, range and security.

Converting Waste Agricultural Biomass into a Resource. How a Rice Miller an Earn Extra Income in Extraction of Ultrapure Silicon from Rice Husk Ash Project
Rice Husk, generally considered as agricultural waste, is mainly used for energy generation, and also used as raw materials to develop technological products such as high purity silica ash, silicon carbide and zeolites. A major inorganic component of RICE Husk is silica (about 20-30 wt. %). Upon leaching with mineral acid and calcination, silica with high purity in amorphous form could be extracted from RICE HUSK. In the past few years our group used ricse husk silica (RICE HUSKS) in the synthesis of different kinds of zeolites including NaY, BEA, MOR, and mesoporous MCM.

Electric cars are automobiles, which are powered by the electric engine and electric energy. The development of the electric vehicles is a very perspective and important process. Scientists and engineers managed to create electric engines which are no less effective than the ordinary engines used today. It is obvious that electric cars are more ecologically safe and require less energy for work. EVs provide fast acceleration by delivering power instantly to the wheels by providing high torque at low speeds; they give a feel of smooth and quick responsiveness (Technology).

FHSS Chops up the data being sent and transmits chunks of it on up to 79 frequencies. 1600 hops/sec- time slot is defined as 625 microseconds Packet 1-5 time slots long FHSS is used to minimize the risk of such interference with systems operating on this Band such as microwave ovens, baby monitors and 802.11 wireless networks. GFSK When we jump from (1,-1 or -1,1), mod waveform changes rapidly, introducing large out of bound spectrum.(no overshoot to a step function input ) Uses Gaussian filter (uses G.Function) to limit its spectral width. GFSK = Baseband pulses(-1,1) gaussian filter FSK modulator FSK = Baseband pulses(-1,1) FSK modulator 1Mb/s with overhead, this effectively becomes 721 kbps. SIG 5 companies joined to form the Bluetooth Special Interest Group (SIG) in 1998. First specification released in July 1999
Most powerful devices Infrared IrDA (WPAN) : synchronization, link between a phone and a laptop… – Less flexible than Bluetooth, need of a line of site – Comparable data rate Wi-Fi (WLAN) : Wireless LAN access – Far higher bandwidth and data rate than Bluetooth – Higher power consumption than Bluetooth – Requires infrastructure investment
The slaves in a piconet can only have links to the master. Slaves cannot directly transmit data to one another
IBM Research P. Bhgwat
Devices that participate in two or more piconets may act as gateways, forwarding traffic from one piconet to another Bluetooth units can only transmit and receive data in one piconet at a time. As devices in mulltiple piconets divide their time between the piconets, spending some time slots in one and some time slots in another on TDM basis. Devices give notification of inactivation to master that it will be inactive for a predetermined length of time. The device will then have to re-synchronize its clock with its other master. When a slave becomes inactive in a piconet, communications between masters and the other active slaves go on as normal. On the other hand, when a master becomes inactive in its piconet, the slaves will have to wait for it to be active again before communication can resume.
The radio layer describes the physical characteristics a Bluetooth device’s receiver-transmitter component must have. These include modulation characteristics, radio frequency tolerance, and sensitivity level.
See ACL links
See ACL links OBEX The Object Exchange Protocol (OBEX) is a specification for object data exchange over infrared (IR) links. Examples for using OBEX include exchanging business cards and synchronizing calendar applications.

Enough said
Standardized protocol supports interoperability of devices of different types.
Interference with other devices that use the same frequency such as baby monitors, microwave over etc. FHSS is used to avoid it.
Many companies are designing and researching impressive bluetooth applications in demand so this shows it has a bright future and it would be difficult for other technology to overcome.
