While wifi stands for Wireless Fidelity. Wifi; 1. How do they differ from each other in electromagnetic wave with respect to frequency and wavelength? Compare and contrast the Bluetooth and WiFi technologies. Compare and contrast the Bluetooth and WiFi technologies. 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). WiMax connection can transmit upto 70 mbps. Each one enables both voice and data traffic; and each one is designed for relatively short-range, low-power operation. HomeRF and Bluetooth technologies have many parallels. Outdoor cellular technologies such as GSM, CDMA, WiMAX, LTE, Satellite etc. Latest posts by Prof. Fazal Rehman Shamil, Peer to Peer Network – Characteristics, Advantages, Disadvantages, Infrared used pulses of infrared light that not visible by naked eyes, Infrared transfer data over the 10 millimeters, Communicating devices can be placed anywhere in an effective range, Communicating devices must be close to each other, It mostly used in mobile phones for data transmission, It mostly used in home electronic devices, It needs line of sight or points to point transmission. 1. WiFi, short for Wireless Fidelity. It is supported on smartphones, computers, smart watches, smart TVs, etc. 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. Log in. • As shown a WiFi AP or Router is connected to the internet using a broadband cable or with cellular network. 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. Question : a. Wi-Fi can triangulate the customer’s location when the device sends the access point's BSSID (MAC address). WiFi, perhaps even more so than Bluetooth, likely requires little introduction. separately in other articles. In this article, we’ll look at the different wireless connectivity technologies in a bit more detail and compare them in terms of the most important attributes applicable in the case of commercial and industrial IoT applications. Wi-Fi, on the other hand, allows devices to connect to the See chart below for a comparison of these technologies. It is known as wireless technology. (3) IrDA is a line of sight technology. 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. It supports short-range and performance is the degrade with long-distance, It can easily handle only one device at one. Bluetooth: IrDA: Physical medium: RF (radio) infrared light (850 nm) Operating Frequency: 2.402 - 2.480 GHz (ISM band ) infrared light frequencies: Data Rate b. Unlike infrared technology, Bluetooth isn't a line of sight method and it provides ranges of up to 300 plus feet. BlueTooth ZigBee WiFi ZigBee By: Mostafa Ali 2. List the differences between Bluetooth vs Infrared. Question 2. a. Which of these do you think dominate the future? Explain the difference between a core specification and a profile specification in the Bluetooth standard. WiFi Related Links. The first products using these technologies were available by 2001. Another difference between Bluetooth and Wifi is that limited number of devices have provision to connect with other devices in Bluetooth. What are the main difference between 'Bluetooth' &'Infrared' technology? Infrared is point to point but Bluetooth is one to multiple point technology. Both technologies are effective, but because of their very different capabilities and limitations, they are best suited to very different applications.  It avoids interferences from other devices. 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). Bluetooth mostly used in mobile devices. Bluetooth allows for a wireless Personal Area Network (PAN) with it's short range. WiFi or Wireless Fidelity, has a range of about 100m and allows for faster data transfer rate between 10 - 54Mbps. Describe the application areas supported by Bluetooth. Describe the application areas supported by Bluetooth. Effective range for infrared is very short. Two other technologies of interest, namely IrDA and HomeRF, are Bluetooth devices send out a much weaker signal than other wireless devices, measuring in at only 1 milliwatt. The IEEE™ 802.15 standards work also addresses WPANs and the IEEE™ 802.11 working group addresses wireless LANs; this work is discussed Today when we hear “wireless,” we likely don’t picture a radio. For more technical resources and information relating to Bluetooth see the official Bluetooth site. Local Area Network (LAN) Technologies. b. b. WLAN (also commonly referred to as WiFi) is the most widely used wireless standard. We choose to discuss HomeRF and IrDA because they have interesting relationships with Bluetooth wireless technology. Infrared is narrow angle 30°. 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. Then the custom panel can be set according to one's own preference. IrDA is an infrared wireless communication technology developed by the Infrared Data Association. wireless network refers to the use of infrared or radio frequency signals to share information and resources between devices. Infrared wireless is more effectively used by the device that closes to each other and relatively stationary. WiFi is known as a Local Area Network (LAN) technology due to its moderate coverage area. Infrared is better used for direct connections while the Bluetooth is capable of connecting from one point to another or more at a specified range. The term “wireless” has been in use for more than a century. 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. Compare and contrast the Bluetooth and WiFi technologies. What is a usage model? It uses very low power which means it is ideal for integration into tiny battery powered devices. 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. Here we compare and contrast specific features of these technologies. WiFi radios are more powerful than it Bluetooth counterparts 4. Inventory control devices can use Bluetooth technology. Because infrared uses the nonvisible infrared light spectrum, IrDA communication is blocked by obstacles that block light (such as walls, doors, briefcases, and people). Bluetooth® Bluetooth technology is one solution for wireless personal area networks (WPANs). The following are the differences between Bluetooth and Infrared: Versatility: Bluetooth devices could work together; where as infrared devices need to be specially designed for specific devices. 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. The devices used for wireless communication are cordless telephones, mobiles, GPS units, ZigBee technology, wireless computer parts, and satellite television, etc. Explain the difference between a core specification and a profile specification in the Bluetooth standard. Describe the application areas supported by Bluetooth. See chart below for a comparison of these technologies. WiMax is long range technology. FIGURE 2: Bluetooth Network VI. 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. Join now. Bluetooth wireless communication occurs at a raw data rate of 1Mbps, with higher speeds being investigated. HomeRF was designed from the outset for home networking environments, whereas Bluetooth technology is optimized for use with WPANs and mobile. WiFi has a lot more bandwidth than Bluetooth b. Explain the difference between a core specification and a profile specification in the Bluetooth standard. (2)(3) Range: IrDA has a max range of 1-2 meters, while NFC is measured in centimeters. An interesting thing about the name “Bluetooth” is that it is far older than wireless technology. The initial IrDA data rate of 115 kilobits per second (Kbps) has now been enhanced to 1 megabit per second (Mbps), comparable to that of the first Bluetooth radios. 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. Question 1. a. Bluetooth used to transfer data using radio waves. The ad… 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 wireless communications because the two technologies share some similar usage models and protocols. Whereas it requires wireless adapteron all devices and wireless router for connectivity. 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). The Bluetooth technology is developed by the Bluetooth special interest group and its physical range is from 10m to 100m. Bluetooth and infrared wireless technologies are commonly used for short-range wireless communication between electronic devices. With optional power amplification of up to 20 dBm, range on the order of 100 meters can be achieved. 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 used to transfer data using radio waves. 1. The two technologies do have differences, though. Bluetooth was formed in 1994 by the tech giant, Ericsson. HomeRF, like Bluetooth wireless technology, 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). Bluetooth consumes low power. Contrast ratio: 1560 (nominal), 2. Strictly speaking, these technologies Explain the difference between a core specification and a profile specification in the Bluetooth standard. Describe the application areas supported by Bluetooth. If your product requires access to the internet, and will always be used near a WiFi access point, then WiFi is the answer. IrDA range is about 1 meter and, as noted already, generally requires a line of sight to establish a connection. Bluetooth used to transfer voice and data. Join now. b. Two reasons: Weaker Signals. Following are the features of WiFi technology as depicted in the figure-2. For wifi technically there is no limit for the clients but effective limit (optimum) is 15 clients. Infrared is a wireless technology that lets devices to communicate with each other using short range wireless signals. In other words the sensors of both the devices must be in each other's immediate line of sight. The IoT is gaining more ground each year. 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. Wifi and Bluetooth are the most famous wireless technology that creates and managed wireless network with the of radio frequency waves. However, Frost & Sullivan does not expect Infrared to disappear altogether. Fi. It is used to transfer data on a particular frequency of 2.4 gigaHertz.It is used to send data from one device to another. It helps you wirelessly connect with other devices in the vicinity, such as your headphones, headset or someone else’s phone, and also exchange data. Orientation: Infrared devices are direct line-of-sight; where as Bluetooth devices could communicate even in times of separation by obstacles. To put it short, the applications with Bluetooth are virtually endless. 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. It is not a very big issue for these limitations. It is used for the wireless communication between the two devices.it is used to send data on a short distance. Inventory control devices can use Bluetooth technology. is a relatively short-range RF communications scheme that operates in the 2.4 gigahertz (GHz) industrial, scientific, and medical (ISM) band. 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. (Read also: More Than Moore: 50 Years of Moore's Law. b. Other techniques also can be used to minimize the problem of RF interference among these and other RF emitters in the ISM band. With Infrared, the devices can transfer data in a bidirectional way. 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. described here. 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 … Bluetooth used Radio waves for the transmission of data instead of light. Question : a. What is the Best? All of these considerations, both objective and subjective, may influence the choice of a WPAN technology for a particular application. WiFi. 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. Question 1. a. So, mobile devices need to connect wirelessly and quickly, hence the two wireless broadband methods: cellular and WiFi. However, like WiFi, Bluetooth also operates on the same radio frequency band at 2.45GHz, but the potential for interference is a lot lower. Other Bluetooth Applications. Bluetooth used to transfer data on the rate of 1 and 3 megabits per second. … There you have it, all of the finely combed details about the two most popular wireless technologies ruling the world – WiFi and Bluetooth.
