# The Computer Revolution/Networks/Bluetooth
## King Harold

    The wireless technology called Bluetooth is named after the Danish King Harold Blatand (Harold Bluetooth). As Harold was largely responsible for the unification of warring parties of Sweden,Denmark, and Norway, similarly,the modern Bluetooth is responsible for the unification or better yet communication of businesses worldwide.

## Bluetooth more specifically

    Bluetooth is a wireless short range communications specification supported by a special interest group comprised of Ericsson, Nokia, Intel, IBM and Toshiba. It allows cable free connectivity between mobile phones, mobile PCs, printers, and hand helds. The range of Bluetooth is 10 meters (30 feet). It supports voice or data transmissions at a rate of up to 1Mbps and has a frequency range of 2.4 to 2.4835 GHz. It is specifically designed to replace the use of cables between devices, such as to connect wireless keyboard or wireless mouse to the desktop computer. Bluetooth technology is even used to send print job wirelessly from a portable computer to a printer or it is used to connect two mobile phones for transferring certain data like music or files. In today’s world Bluetooth Technology is available in cars too, so that the mobile phone is connected to car Bluetooth and it enables the driver to receive or make calls or even connect his music files to the car stereo system. The signals of Bluetooth can transmit through clothing or other non-metallic objects; hence it can connect directly to any Bluetooth Technology encrypted device.

## More on Bluetooth

    Bluetooth is a radio technology that allows exchange of communications even in areas with electromagnetic disturbances. It is replacing cable or infrared devices by making use of low cost transceiver chips that are embedded in the mobile devices. It also makes use of built in encryption and verification codes which allow the secure transfer of information.
Telemedicine
Telemedicine Today is the leading news and information source for the telemedicine industry, with a readership that includes telemedicine practitioners, physicians, hospital administrators, healthcare information specialists, vendors, consultants, policy makers, and others interested in this dynamic field. Telemedicine is the use of networking technology to provide medical information and services and is mosIt is specifically designed to replace the use of cables between devices, such as to connect wireless keyboard or wireless mouse to the desktop computer.

For example, physician can use Videoconferencing to communicate remotely with other physician or with hospitalized patients. Physicians can also use telemedicine to perform remote diagnosis of patients. For example, healthcare workers at rural locations, childcare facilities, and other locations can use video cameras, electronic stethoscopes, and other devices to send images and vital statistics of a patient to a physician located at a medical facility. There is another example of telemedicine is telesurgery - a form of robot assisted surgery where a robot controlled by a physician operates on the patient. At least one of the surgeons performs the operation by controlling the robot remotely over the Internet or another network. Robot assisted surgery systems typically use cameras to give human surgeon an extremely close view of the surgical area. Telemedicine has a huge potential for providing quality medical care to individuals who live in rural areas or underdeveloped areas that do not have access to medical care. It will also be necessary for future long-term space explorations. NASA astronauts and physicians recently performed telesurgery experiments in the Aquarius Undersea Laboratory 50 feet below the ocean surface to help in the development of a robotic unit that will allow physicians to perform surgery remotely on patients who are in outer space. Telemedicine is not a separate medical specialty. Products and services related to telemedicine are often part of a larger investment by health care institutions in either information technology or the delivery of clinical care.
Telepharmacy
Just like telemedicine, the goal of telepharmacy is to bring healthcare services to remote locations where these services are needed. Telepharmacy takes advantage of network technology to bring pharmacy services to those remote areas where a pharmacist is needed. Telepharmacies can stock typical inventory of prescription as well as over-the-counter medications and appear just like full-service retail pharmacies or they can exist within institutional settings such as hospitals. The way telepharmacy works is that the telepharmacy is always staffed by a pharmacy technician who can accept prescription orders from patients. The order is then prepared by the technician for final check by the pharmacist. The pharmacist will then review the patient's profile of concurrent medications to identify any issues such as drug interactions or allergies and will also check the prescription order prepared by the technician using the same network technology. Patient counseling is also conducted via videoconferencing which is conducted inside a private consultation room where the technician will direct the patient to speak with the pharmacist privately. From start to finish, the same pharmacy services can be provided to patients through the use of videoconferencing and the safe delivery of pharmacy services still remains the responsibility of the pharmacist.
