WiFi RealTime Location Tracking Systems Essay Example for Free

wireless local area network RealTime Location Tracking Systems EssayWrireless networks has affected large and small companies alike. term Radia Frequency Identification (RFID) marks based networks collect gained popularity over the years, there be also other tuner networks available that are being tested in order to provide same functionality and more. Wi-Fi and blue tooth are two of the examples of such networks. This short paper discusses the use of Wifi. Wi-Fi Networks WiFi generally comes under the umberalla of RFID. WiFi ID is in reality an active agent RFID constitution that uses the air communication standard 802. 11.There are also other active RFID systems that use standards other than 802. 11 and operate on different frequencies. One of the important aspect of this scenerio is to envision thje difference between the RFID tags and Wifi tags. RFID Tags vs. WiFi Tags In order to use passive RFID tags, you necessity to have reader after every few feets to read the tag. For active RFID tags a radio sensor require to be deployed that uses different technologies to sense the tags in order to determine the location of the tag. Antennas are also required. This style that you need to built an root word to deploy both types of systems.Like Best Buy is doing. When you are exploitation a WiFi based system that are aslo called Real Time Location Systems (RTLS), you only need to station up the WifFi network in the company and bear use any underlying engineering science in order to make it work. RFID tags can also be used here, but adavnatge is that you dont need to set up the RFID network infratsurcture that you needed to incorporate before. In RFID tags, for short range identfication, High frequency tag is used and for short range identification, active UHF tags are used that operate on 900 megahertz or 433 MHz.Both these type, as discussed require a complete insfrastructure to be built. However, WiFi operates on 2. 4 GHz. These 2. 4 GHz can be used in the network. For a company like BestBuy, choosing WiFi has an extra advantage that it give already have 802. 11 network infrastructures in place and this will save money for the company. The only things they need to buy are the WiFi tags. Applications The WiFi network infrastructure can provide many application to the companies like BestBuy and some of them include location-based network access, intelligent selective information management and wireless asset introduce.The WiFi tags can exactly point by the location of the tag. This can also mean that customer walking into the store can have the contents on his labor organizer according to the position where he is standing. Statistical reports can be generated n the basis of information of how more than time a customer spends at a particular location and what consequences this can have employ data mining techniques. Once the tagging has helped a customer locate items and a shopping list has been completed, the system can store this list for future reference to the particular customer.The underlying software can mug up a probable list of items for that particular customer. Another important application of WiFi tags can be theft prevention. For example, if a certain item is to be protected, the system will attach a fleur-de-lys to it whenever it is taken from the shelf and added to a cart. The system can then track the item until it reaches the check out line. If the item does not reach the check out line and leaves the store, it will be an indication of a theft and action can be taken against the customer. Therefore, the WiFi network can be industrious for security of valuable assets as well.Therefore, WiFi tags can be used beyond item tracking systems such as inventory control systems to easily manage large inventory.
