It is supported on smartphones, computers, smart watches, smart TVs, etc. Log in. Radio frequency interference is to be expected in the unlicensed 2.4GHz ISM band. Takeaway: Bluetooth and Wi-Fi, as wireless technologies have similarities, but the differences are significant. Log in. Bluetooth is essentially used to connect short-range devices for sharing data while Wifi provides high-speed internet access. 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. Inventory control devices can use Bluetooth technology. Bluetooth also uses the ISM band, but Wi-Fi technology doesn’t rely solely on the proximity of the user. It required line-of-sight between the sender and receiver. Question 2. a. b. The devices used for wireless communication are cordless telephones, mobiles, GPS units, ZigBee technology, wireless computer parts, and satellite television, etc. WiFi is used largely in computers and PDAs while Bluetooth is widely used in mobile phones 3. It is refers to a network that connects two or more devices by using wireless data connections over short distances. while it consumes high power. It provides very high data throughput but it is more vulnerable to interference than Bluetooth. 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). While wifi stands for Wireless Fidelity. These pulses are invisible to the naked eye, but can be detected by… 1. # The two main technologies that computers can use to communicate wirelessly are listed below: Wi-Fi; Bluetooth. Compare and contrast the WiFi IEEE 802.11ax standard and latest Bluetooth standards. technologies are described next, with the objective of providing a context in which Bluetooth wireless communications as a WPAN technology can be better understood. is a relatively short-range RF communications scheme that operates in the 2.4 gigahertz (GHz) industrial, scientific, and medical (ISM) band. Inventory control devices can use Bluetooth technology. Explain the difference between a core specification and a profile specification in the Bluetooth standard. And now it’s popular in different applications, like the wireless keyboard. Another difference between Bluetooth and Wifi is that limited number of devices have provision to connect with other devices in Bluetooth. We know infrared has very low range and Bluetooth has about 10 meter range. Due to  Line of Sight limitation infrared wireless is mostly used in devices that are placed in one place are close to each other. Compare and contrast the Bluetooth and WiFi technologies. Compare and contrast the Bluetooth and WiFi technologies. (Read also: More Than Moore: 50 Years of Moore's Law. Orientation: Infrared devices are direct line-of-sight; where as Bluetooth devices could communicate even in times of separation by obstacles. b. The maximum range of Bluetooth Is 10 meters. The main difference between Bluetooth and Wifi is the purpose behind its designing. However, the use of Bluetooth currently involves licensing certain key patents. Infrared uses electromagnetic radiation principle where wavelength of the emitting light corresponds to the frequency range of 1~400Thz.This is used for the communication purposes on different schemes like Near infrared (0.75 - 1.4um), Short infrared (1.4um - 3um), Mid infrared (3-8um), Long infrared (8 - 15um), Far infrared (15um - 1000um) Bluetooth used to transfer data using radio waves. The effective range for Bluetooth wireless communication is about 10 meters using the standard 0 dBm radio. Describe the application areas supported by Bluetooth. Today, IrDA can achieve data rates of up to 4Mbps, with even higher rates already specified and beginning to be implemented. Unlike infrared technology, Bluetooth isn't a line of sight method and it provides ranges of up to 300 plus feet. Bluetooth allows for short-range data transfer between devices. domain: wearable computing devices are becoming more popular and could be considered WPANs or elements of WPANs. b. 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.  It avoids interferences from other devices. Certainly there are other technologies that could be employed in the WPAN In other words, the Bluetooth standard is less open than IrDA. Bluetooth used to transfer voice and data. Strictly speaking, these technologies 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 uses pulses of infrared rays to transmit data,bluetooth uses radiowaves of 2.4GHz frequency.The range of bluetooth is 2times larger than infrared and … If you do not have line of time, you cannot connect. WiMax connection can transmit upto 70 mbps. It is known as wireless technology. Although both are wireless forms of communication, Bluetooth and Wi-Fi differ in terms of their purpose, capabilities, and other factors. It is used for the wireless communication between the two devices.it is used to send data on a short distance. Still, it is commonly used in computer other peripheral devices. The Differences Between Bluetooth, ZigBee and WiFi 1. List the differences between Bluetooth vs Infrared. Bluetooth is a wireless technology standard that uses short-wavelength UHF radio waves (2.4 GHz to 2.485 GHz) to transmit and receive data over short distances (typically within the range of 10 meters). Satellite Satellite communication is one of the wireless technologies, which is widely spread all over the world allowing users to stay connected virtually anywh… Wifi and Bluetooth are the most famous wireless technology that creates and managed wireless network with the of radio frequency waves. However, Bluetooth technology can add convenience and user mobility by relaxing the device alignment and line of sight requirements of IrDA communications. (1) Explain the difference between a core specification and a profile specification in the Bluetooth standard. 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). 3. Bluetooth and Wi-Fi . In other words the sensors of both the devices must be in each other's immediate line of sight. Ask your question. WiMax versus Wi-Fi A Comparison of Technologies, Markets, and Business Plans Michael F. Finneran dBrn Associates, Inc. Telephone: (516) 569-4557 Email: mfinneran@att.net. b. WiFi radios are more powerful than it Bluetooth counterparts 4. Compare and contrast the Bluetooth and WiFi technologies. Bluetooth is a type of wireless technology, mostly has short range, coverage and used for source of connection between mobiles, computers and multiple electronic devices. 1. Bluetooth Related Links. Cell phones are connected to hands-free earpieces, wireless keyboard, mouse and mike to laptops with the help of Bluetooth as it transmits information from one device to other device. Bluetooth technology is used in more than headsets, though. b. 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. 2. Infrared wireless is more effectively used by the device that closes to each other and relatively stationary. Ideal to be used for controling your TV, speakers, air condition, door, projector etc this Wi-Fi to IR and RF Smart Wi-Fi Remote Controller lets you have fun and full control over your home appliances. Although twice that of infrared. Other Bluetooth Applications. IrDA is an infrared wireless communication technology developed by the Infrared Data Association.
