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). Bluetooth mostly used in mobile devices. Describe the application areas supported by Bluetooth. The IEEE™ 802.15 standards work also addresses WPANs and the IEEE™ 802.11 working group addresses wireless LANs; this work is discussed Bluetooth allows for a wireless Personal Area Network (PAN) with it's short range. Other techniques also can be used to minimize the problem of RF interference among these and other RF emitters in the ISM band. List the differences between Bluetooth vs Infrared. technologies are described next, with the objective of providing a context in which Bluetooth wireless communications as a WPAN technology can be better understood. Ask your question. Bluetooth works in lower distance range than in comparison to a typical wireless LAN. 4. Bluetooth and Wi-Fi . Both Bluetooth wireless technology and IrDA communication are optimized for low power consumption and low cost. Like Bluetooth wireless communications, HomeRF operates in the 2.4GHz ISM band, using radio waves for relatively short-range voice and data communication among various types of devices. In recent days, the wireless communication technology has become an integral part of several types of communication devices as it allows users to communicate even from remote areas. Question 2. a. 1. RF transmission patterns radiate in some pattern (ideally, spherical) around the radio antenna, so any two devices within range can communicate with each other, whether or not they are "pointed at" each other (in fact, the second device might not be visible at all to the user of the first device, as it could be in another room behind doors and walls or even on another floor of a building, for example). WiFi. 2. b. Wi-Fi can triangulate the customer’s location when the device sends the access point's BSSID (MAC address). For wifi technically there is no limit for the clients but effective limit (optimum) is 15 clients. It is known as wireless technology. It would be self-defeating if a mobile device, such as a smartphone or tablet, could only connect to the Internet when plugged into a landline. Bluetooth allows for short-range data transfer between devices. Infrared devices are much greater than that of Bluetooth devices The most common speed for infrared is 3 Mbps. 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 is a short range technology standard which allows devices to communicate in a wireless manner. WiFi is used to wirelessly connect computers to a network while Bluetooth is used to wirelessly connect two devices to each other 2. Bluetooth technology is used to send and receive data and information using Bluetooth-enabled mobile devices such as a smartphone, laptop, tablet, or any Bluetooth-enabled device. Question 2. a. What is a usage model? Bluetooth and WiFi are different standards for wireless communication. Technically, Wifi is based on IEEE 802.11 standard and has several variants that include 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac. Security: IrDA does not have security built in, and does not support encryption technologies such as SSL to cover that, where NFC at least supports SSL. If you do not have line of time, you cannot connect. Log in. If you have to send data from one mobile to the other using infra-red technology, you will have to keep both the mobiles facing each other. Internet wireless transmits data in the range between 115 kilobits per second and 15 megabits per second depending upon the device and also depends upon the position of the devices. It is refers to a network that connects two or more devices by using wireless data connections over short distances. Some of these technologies include standards such as ANT UWB, Bluetooth, ZigBee, and Wireless USB. Bluetooth technology is useful when transferring information between two or more devices that are near each other when speed is not an issue, such as telephones, printers, modems and headsets. It is supported on smartphones, computers, smart watches, smart TVs, etc. It used wireless infrared pulses for transmission of data,these pulses are not seen by the human eye but can be detected by a sensor in receiving data. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Experts project there will be 75 billion connected devices by 2025. An interesting thing about the name “Bluetooth” is that it is far older than wireless technology. Compare and contrast the Bluetooth and WiFi technologies. WiFi, short for Wireless Fidelity. It is known as wireless technology. It uses very low power which means it is ideal for integration into tiny battery powered devices. wireless network refers to the use of infrared or radio frequency signals to share information and resources between devices. Each one enables both voice and data traffic; and each one is designed for relatively short-range, low-power operation. Bluetooth: IrDA: Physical medium: RF (radio) infrared light (850 nm) Operating Frequency: 2.402 - 2.480 GHz (ISM band ) infrared light frequencies: Data Rate Other Bluetooth Applications. Simply put, Bluetooth is an exchange protocol used for communication of data between two devices in close range. IrDA range is about 1 meter and, as noted already, generally requires a line of sight to establish a connection. Effective range for infrared is very short. Although both are wireless forms of communication, Bluetooth and Wi-Fi differ in terms of their purpose, capabilities, and other factors. You can share a small piece of data in shape of image, music, video or documents to interconnected mobile, laptop or head set (for music and calls). While wifi stands for Wireless Fidelity. 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. Whereas it requires wireless adapteron all devices and wireless router for connectivity. See chart below for a comparison of these technologies. With Infrared, the devices can transfer data in a bidirectional way. Today when we hear “wireless,” we likely don’t picture a radio. Bluetooth is a low powered 2.4 GHz frequency radio communication technology. Answer to 1. a. Local Area Network (LAN) Technologies. Join now.
