For more technical resources and information relating to Bluetooth see the official Bluetooth site. Orientation: Infrared devices are direct line-of-sight; where as Bluetooth devices could communicate even in times of separation by obstacles. Whereas it requires wireless adapteron all devices and wireless router for connectivity. Bluetooth has no full form. The signal wavelength used with Bluetooth communication (about 12.5 cm, at its associated frequency of 2.4GHz) is three orders of magnitude greater than that of IrDA. Another difference between Bluetooth and Wifi is that limited number of devices have provision to connect with other devices in Bluetooth. Explain the difference between a core specification and a profile specification in the Bluetooth standard. It is refers to a network that connects two or more devices by using wireless data connections over short distances. Bluetooth Related Links. Question 1. a. Key Words: Wi-Fi, Bluetooth. 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). 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. WiFi is short range technology. What is a usage model? The first products using these technologies were available by 2001. # The two main technologies that computers can use to communicate wirelessly are listed below: Wi-Fi; Bluetooth. The main difference between Bluetooth and Wifi is the purpose behind its designing. WiFi or Wireless Fidelity, has a range of about 100m and allows for faster data transfer rate between 10 - 54Mbps.

Compare and contrast the WiFi IEEE 802.11ax standard and latest Bluetooth standards. Initially, the data rates of the two technologies were similar at about 1Mbps; recently, HomeRF version 2.0 has specified data rates up to 10Mbps. List the differences between Bluetooth vs Infrared. Because infrared uses the nonvisible infrared light spectrum, IrDA communication is blocked by obstacles that block light (such as walls, doors, briefcases, and people). So, mobile devices need to connect wirelessly and quickly, hence the two wireless broadband methods: cellular and WiFi. Log in. • It consists of two important devices namely, a Wi-FI router or Access point(AP), Wi-Fi dongle and Wi-Fi stations. • As shown a WiFi AP or Router is connected to the internet using a broadband cable or with cellular network. However, Frost & Sullivan does not expect Infrared to disappear altogether. 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. IrDA is an infrared wireless communication technology developed by the Infrared Data Association. Bluetooth: IrDA: Physical medium: RF (radio) infrared light (850 nm) Operating Frequency: 2.402 - 2.480 GHz (ISM band ) infrared light frequencies: Data Rate Infrared waves are damaged by dust Smoke for sunlight etc. 1. Bluetooth is essentially used to connect short-range devices for sharing data while Wifi provides high-speed internet access. 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. WiFi doesn’t have the same limitations, but how many devices a WiFi network can handle will be largely determined by the bandwidth of the router you are connected to. What is the Best? 1. See chart below for a comparison of these technologies. It required line-of-sight between the sender and receiver. These and other mechanisms can be employed to implement WPANs, but each is optimized for specific usage, applications, or domains. b. The mooted future increases in the data rate of Bluetooth and the resolution of short-term security issues should strip away most of the remaining advantages of Infrared as a wireless connectivity technology. Here we compare and contrast specific features of these technologies. Bluetooth, Infrared, NFC, Wi-Fi and LiFi are the different wireless technologies that exist. 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. 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. Like the Infrared Data Association, it's a consortium of companies that prefer standards to chaos. Question 2. a. Today when we hear “wireless,” we likely don’t picture a radio. 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. Still, it is commonly used in computer other peripheral devices. What is the range of their connectivity? Wi-Fi Wi-Fi stands for Wireless Fidelity, which refers to wireless technology that allows devices to communicate over a wireless signal.

It is supported on smartphones, computers, smart watches, smart TVs, etc. Both Bluetooth wireless technology and IrDA communication are optimized for low power consumption and low cost. described here. WiFi has a lot more bandwidth than Bluetooth Other techniques also can be used to minimize the problem of RF interference among these and other RF emitters in the ISM band. b. The battery used in infrared devices run for a long time, The infrared technology is more effective for devices that are close to each other close more than 10 millimeter, Infrared wave at high power can damage the eyes. 2. WiFi is used largely in computers and PDAs while Bluetooth is widely used in mobile phones 3. WLAN (also commonly referred to as WiFi) is the most widely used wireless standard. It is not a very big issue for these limitations. separately in other articles. Bluetooth and Wi-Fi . Compare and contrast the Bluetooth and WiFi technologies. Inventory control devices can use Bluetooth technology. The effective range for Bluetooth wireless communication is about 10 meters using the standard 0 dBm radio.  It avoids interferences from other devices. WiMax network can reach about 50-90 km. Explain the difference between a core specification and a profile specification in the Bluetooth standard. b. In other words the sensors of both the devices must be in each other's immediate line of sight. Indoor wireless technologies such as Wireless LAN(or WiFi), Bluetooth, IrDA, Zigbee, Zwave etc. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Bluetooth is a short range technology standard which allows devices to communicate in a wireless manner. Depending on the version, Bluetooth has a range of 5 meters to 30 meters. 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. Compare and contrast the Bluetooth and WiFi technologies. All of these considerations, both objective and subjective, may influence the choice of a WPAN technology for a particular application. The Differences Between Bluetooth, ZigBee and WiFi 1. If you do not have line of time, you cannot connect. Compare and contrast the Bluetooth and WiFi technologies. Outdoor cellular technologies such as GSM, CDMA, WiMAX, LTE, Satellite etc. With optional power amplification of up to 20 dBm, range on the order of 100 meters can be achieved. Wi-Fi is a wireless Local Area Network (LAN) technology where two or more electronic devices use the ISM radio bandto communicate. If you have a smartphone, then you likely know about Bluetooth and what it does. Explain the difference between a core specification and a profile specification in the Bluetooth standard. Some of these technologies include standards such as ANT UWB, Bluetooth, ZigBee, and Wireless USB. WiFi is known as a Local Area Network (LAN) technology due to its moderate coverage area. Question 1. a. Orientation: Infrared devices are direct line-of-sight; where as Bluetooth devices could communicate even in times of separation by obstacles. The term “wireless” has been in use for more than a century. Your comparison should be based on technical specification and performance (e.g., data rate, modulation, range, no of channels and MIMO antenna, security features and other parameters; you should list as … Which of these do you think dominate the future? The Bluetooth technology is developed by the Bluetooth special interest group and its physical range is from 10m to 100m. Refer page on wifi tutorial. With all other factors being equal, higher data rates and greater range require more power consumption, so HomeRF often could require more power, although both technologies include power-saving schemes in their respective specifications. 1. Unlike infrared technology, Bluetooth isn't a line of sight method and it provides ranges of up to 300 plus feet. Though these licenses are free, you must agree to some terms. Why do they have limited connectivity zone? WiMax connection can transmit upto 70 mbps. We're entering a world in which WiFi and Bluetooth may no longer be the best communication technologies for Internet of Things (IoT) applications. Bluetooth technology is one solution for wireless personal area networks (WPANs). WiFi, short for Wireless Fidelity. With Infrared, the devices can transfer data in a bidirectional way.
