Bluetooth is a short range technology standard which allows devices to communicate in a wireless manner. The difference between Bluetooth and Wi-Fi is just similar to the differences between Infrared (old method) and Bluetooth, yes WiFi is an advanced wireless connectivity like and for Bluetooth type. Explain the difference between a core specification and a profile specification in the Bluetooth standard. Bluetooth VS infrared – Comparison of Range and transmission speed Range Of Bluetooth. Bluetooth used to transfer data on the rate of 1 and 3 megabits per second. Wifi; 1. It was named after a 10th Century Danish King and Viking, Harald Bluetooth who united Denmark from numerous tribes. BlueTooth ZigBee WiFi ZigBee By: Mostafa Ali 2. See chart below for a comparison of these technologies. In addition to technical differences such as packet structure and protocol layers that are not detailed here, other characteristics distinguish them. Bluetooth is a short range technology standard which allows devices to communicate in a wireless manner. Wifi, short for Wireless Fidelity, is a wireless technology that uses radio frequency to transmit data across devices through air. Wi-Fi can triangulate the customer’s location when the device sends the access point's BSSID (MAC address). Infrared is a wireless technology that lets devices to communicate with each other using short range wireless signals. Describe the application areas supported by Bluetooth. Bluetooth has no full form. An interesting thing about the name “Bluetooth” is that it is far older than wireless technology. WiFi radios are more powerful than it Bluetooth counterparts 4. HomeRF, like Bluetooth wireless technology, Bluetooth technology is used in more than headsets, though. Both technologies are effective, but because of their very different capabilities and limitations, they are best suited to very different applications. 2. At this wavelength, radio frequency (RF) communications can penetrate many of these sorts of obstacles. WiFi network range is around 100 meters. Still, it is commonly used in computer other peripheral devices. FIGURE 2: Bluetooth Network VI. Question 1. a. It supports short-range and performance is the degrade with long-distance, It can easily handle only one device at one. HomeRF was designed from the outset for home networking environments, whereas Bluetooth technology is optimized for use with WPANs and mobile. WiFi, perhaps even more so than Bluetooth, likely requires little introduction. What is the range of their connectivity? while it consumes high power. Here we compare and contrast specific features of these technologies. Log in. HomeRF is a wireless radio communications technology developed by the HomeRF working group, an industry consortium not unlike the Bluetooth SIG (in fact, several companies participate in both groups). Wireless technologies are designed to reduce the time and different type of obstacles created by the cables. 2. First introduced in the year 1998, Bluetooth is a wireless technology for data transfer and reception, which was designed specifically for use in mobile devices. Inventory control devices can use Bluetooth technology. Like the Infrared Data Association, it's a consortium of companies that prefer standards to chaos. WiFi Direct, hotspot: Bluetooth: v4.1, A2DP, LE: GPS: Yes, with A-GPS, GLONASS, BDS: Infrared port: No: Radio: FM radio: USB. Bluetooth mostly used in mobile devices. Compared to other RF communication technologies, Bluetooth communication consumes very little power and is projected to have very low module costs in the foreseeable future. With optional power amplification of up to 20 dBm, range on the order of 100 meters can be achieved. Bluetooth used to transfer voice and data. Two reasons: Weaker Signals. Local Area Network (LAN) Technologies. List the important usage models and briefly describe the functions provided and […] Wireless Sensor Networks (WSN / WSAN) are, generically, networks of low-power, low-cost devices that interconnect wirelessly to collect, exchange, and sometimes act-on data collected from their physical environments - "sensor networks". It requires bluetooth adapter on all devices for connectivity. (3) IrDA is a line of sight technology. Ride the Wave. It also wouldn’t be much fun if a fantastic piece of technology and engineering took five minutes to load a webpage. The distance between the two devices is very short from the fixed, mobile device and building personal area network. For instance, more shipping and receiving departments are using Bluetooth-based mobile bar code scanners for accurate, up-to-the-minute inventory control. Explain the difference between a core specification and a profile specification in the Bluetooth standard. Outdoor cellular technologies such as GSM, CDMA, WiMAX, LTE, Satellite etc. Infrared is a wireless device that uses infrared light to transfer data like your TV remote. WiMax is long range technology. technologies are described next, with the objective of providing a context in which Bluetooth wireless communications as a WPAN technology can be better understood. Today, IrDA can achieve data rates of up to 4Mbps, with even higher rates already specified and beginning to be implemented. See chart below for a comparison of these technologies. This network is based on the IEEE standard 802.11; including 802.11a, 802.11b, 802.11g and 802.11n, by using the centralized router devices can share the Wi-Fi signal. WiMax connection can transmit upto 70 mbps. … Wireless LAN (WLAN) stands for Wireless Local Area Network. Recent advances in infrared technology have enabled more diffuse transmission patterns, although much of the IrDA equipment in use today uses a relatively narrowly focused beam, which usually requires that the two devices engaged in IrDA communication be aligned with (pointed at) each other. HomeRF communication range is about 50 meters (designed to cover a typical home), which is greater than the 10-meter range of the typical Bluetooth radio. Explain the difference between a core specification and a profile specification in the Bluetooth standard. Bluetooth® Wi-Fi Wi-Fi stands for Wireless Fidelity, which refers to wireless technology that allows devices to communicate over a wireless signal. IrDA is a specific use of infrared light as a communications medium; Bluetooth technology is a specific use of radio waves as a communications medium. Bluetooth works in lower distance range than in comparison to a typical wireless LAN. It can lose connection in many situations. b. Be able to contrast and compare Wi-Fi and Bluetooth. Examples: Wi-Fi and Bluetooth are the two main ways to connect to networks wirelessly. One means to mitigate RF interference is the use of frequency-hopping spread-spectrum (FHSS), and both of these technologies use FHSS as a way to deal with undesired interference.
