How is Bluetooth is a Modern Application of Physics Essay

Now a day’s android phone are becoming more and more popular because of more number of applications and good storage area. The Bluetooth based robotic car uses communication in Bluetooth frequency range. One of the android phone application “Bluecontrol” is used to set up a connection and to let the phone to communicate with the Bluetooth module on the robotic car. This Bluetooth module receives data/command from mobile phone and send these commands to the microcontroller 8051 to make the car to move forward/ backward and to turn left or

“Tethering” is the sharing a smartphone network connection with another device and allow connections to the Internet via the other device’s connection (Hoffman, 2013).Tethering is frequently used to access the Internet on a laptop using a smartphone data connection (Hoffman, 2013). One item that most people do not realize is they can also tether over Bluetooth and this will consume much less battery power than Wi-Fi would (Hoffman, 2013).

The amplitude affects the strength of the force, that is the length of the force vectors in the electromagnetic wave. The wavelength of the wave depends only on the frequency with which the electron in the transmitting antenna is oscillating up and down; and the speed of light.

The invention of wifi didn't start as, well, wifi. It started with a woman named Hedy Lamar. She was born Jewish during WW2. She fled to America where she became the most beautiful actress ever. People saw her only for her looks, not her brains. She invented many things, stupid things, like a new Kleenex box. But, one day, she thought that if pianos could hop from note to note, so could radios from frequency to frequency. So she and a partner invented Frequency Hopping. Her thought process was if radios hopped from signal to signal, it couldn't be jammed or hacked into. It was called, Frequency Hopping. It was presented to the Navy, and they turned it down. Lamar got a patent for it, but in years later sold it off to the Navy. She watched it

As you probably realized, you use wifi everyday for multiple reasons. What you probably didn't know was how wifi came about. Many years ago, a lady named Hedy Lamar befriended a Hollywood composer named George Antheil. Together, they realized if a player piano could jump from note to note, so could a radio signal. Hedy proposed the idea to the Navy to torpedo German U-Boats in the Atlantic, but she was turned down and told to try and raise money instead. Throughout the years, Lamar's career started to slowly decline as others stole her idea of frequency hopping. In the end, Hedy earned no money from her idea, and her beauty was much more noticed than her brains.

BlueWave is a waterproof, portable, Bluetooth speaker. The Bluetooth 3.0 allows the speaker to be operated off your phone, laptop, iPod or other Bluetooth enable devices without having to have anything plugged

Bluetooth is designed to operate in an environment of many users. Up to eight devices can communicate in a

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

Upgrading your car’s current audio system with a new one supplying built-in Bluetooth is possible and for less than $150 before installation. Look for a system with a

6. What is the difference between Wi-Fi and WiMAX communications? Wi-Fi and WiMAX operate the same in many ways and aspects except that WiMAX cover a greater distance at faster transfer rates. This makes it possible to have less components in a WiMAX configuration than a Wi-Fi covering the same square footage area.

Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”.

Created in 1994, Bluetooth technology was apprehended as a wireless alternate to data cables by exchanging data using radio broadcasts. The name Bluetooth originated from a tenth century Danish King, Harald Blatand or, in English, Harold Bluetooth (Bluetooth, 2016). Bluetooth establishes smaller, continuously connected, networks. Bluetooth 's speed and coverage range is much smaller than Wi-Fi 's, however the trade-off permits Bluetooth to function at much lower energy expenditures and link to different devices in the course of a day that is impeccable for vastly mobile devices with inadequate batteries, such as cellular phones (Gardner, 2003). Bluetooth devices consume radio waves instead of wires or cables to connect to a phone or computer. A Bluetooth artifact, like an earpiece or watch, contains a small computer chip with a Bluetooth receiver and software that enables it to easily connect. When two Bluetooth devices need to communicate with each other, they need to pair. Communication between Bluetooth devices occurs over short-range, ad hoc networks identified as piconets. A piconet is a system of devices linked using Bluetooth technology. The system arrays from two to eight paired devices. When a network is recognized, one device precedes the role of the dominant while all the other devices act as subservient. Piconets are established vigorously and repeatedly as Bluetooth devices enter and leave radio vicinity (Bluetooth, 2016).

Because of its low cost and low power consumption it is widely used and also many companies working towards it and also trying to manufacture small ble module. So, that as technology rate increases day by day the size of this ble module is decreasing. Now a day’s ble tags also available in the market like rfid tags. So, that ble is the solution that we required which will be low cost and low power consumption.

Bluetooth allows devices to connect wirelessly and automatically. In order to make this connection between devices, however, the devices need not be connection through electrical wires, Ethernet cables, or Infrared signals. Bluetooth technology provides an edge over Infra red technology as “they [Bluetooth technology] do not have to be in line of sight of each other” (Wikipedia.org). As a result, Bluetooth enabled devices can be separated by walls and out of sight of each other yet they can maintain the network as far as

Abstract-In this current generation, technology is at its best, which is developing many better things which are easier than it is used to be before. WI-FI which stands for wireless-fidelity which means it is a wireless way to handle networking which helps computers, smartphones, or other devices to connect to the Internet or communicate with one another wirelessly within a particular area. This paper explains information about different communication modules such as Bluetooth, RF and Zig bee in industrial applications. In this paper, an overall comparison of these three modules are made which are based upon their industrial applications and characteristics such as standard, bandwidth, battery life, data rate, and maximum transmission range etc.
