Sample text

In this section, we shall analyze each technology’s advantages and disadvantages, as candidate technologies for use in our positioning purposes. First, we summarise the key features of our application, that directly effect the decision for which technology to be used: 1. quick detection of all devices nearby a base station, 2. ability to detect all kinds of mobile devices used by users, especially popular devices that are being used IrDA (Infrared) is a low cost technology used for many purposes.

This also eases the bottleneck of scanning each item at a time with a faster reading speed. However, this capability has its downside. The fact that, in a RFID system, tags within range are read almost simultaneously also means that the exact sequence of the cartons is not picked up by the reader (Bednarz, 2004). In a conveyor setup, cartons are often required to be routed to different locations. It is therefore important to know the order of the cartons in or- 10 der to direct them to the right locations.

RELATED In the bibliography, there are many positioning systems based on wireless technologies. In previous sections, we have decided Bluetooth to be the ideal technology and the triangulation method to be the most suitable positioning method for our application. In this section, for completeness purposes, we present the most innovative positioning and location aware systems that use not only Bluetooth, but various wireless technologies and positioning methods. RFIDand RFL Location Sensing S ystems The LANDMARC system (Ni, Liu, Lau, & Patil, 2003) uses RFID for locating the position of a user indoors.
