There are besides other active RFID systems that use criterions other than 802. 11 and run on different frequences. One of the of import facet of this scenerio is to understand thje difference between the RFID tickets and Wifi tickets. RFID Tags vs. WiFi Tags In order to utilize inactive RFID ticket. you need to hold reader after every few feets to read the ticket. For active RFID tags a wireless detector needs to be deployed that uses different engineerings to feel the ticket in order to find the location of the ticket. Antennas are besides required. This means that you need to construct an substructure to deploy both types of systems.
Like Best Buy is making. When you are utilizing a WiFi based system that are aslo called Real Time Location Systems ( RTLS ) . you merely need to put up the WifFi web in the company and can utilize any implicit in engineering in order to do it work. RFID tickets can besides be used here. but adavnatge is that you dont necessitate to put up the RFID web infratsurcture that you needed to integrate before. In RFID tickets. for short scope identfication. High frequence ticket is used and for short scope designation. active UHF tickets are used that operate on 900 MHz 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 web. For a company like BestBuy. taking WiFi has an excess advantage that it will already hold 802. 11 web substructures in topographic point and this will salvage money for the company. The lone things they need to purchase are the WiFi ticket. Applications The WiFi web substructure can supply many application to the companies like BestBuy and some of them include location-based web entree. intelligent information direction and radio plus trailing.
The WiFi tickets can precisely indicate out the location of the ticket. This can besides intend that client walking into the shop can hold the contents on his PDA harmonizing to the place where he is standing. Statistical studies can be generated n the footing of information of how much clip a client spends at a peculiar location and what consequences this can hold utilizing informations excavation techniques. Once the tagging has helped a client locate points and a shopping list has been completed. the system can hive away this list for future mention to the peculiar client.
The underlying package can fix a likely list of points for that peculiar client. Another of import application of WiFi tickets can be theft bar. For illustration. if a certain point is to be protected. the system will attach a flag to it whenever it is taken from the shelf and added to a cart. The system can so track the point until it reaches the cheque out line. If the point does non make the cheque out line and leaves the shop. it will be an indicant of a larceny and action can be taken against the client. Therefore. the WiFi web can be employed for security of valuable assets every bit good.
Therefore. WiFi tickets can be used beyond point tracking systems such as stock list control systems to easy pull off big stock list. References ABI Research. ( 2006. October 23 ) .
