Editor's Notes

As we look at several short range technologies, you can see how they cover the gamut in key areas such as throughput and range. You will also notice that some technologies do overlap in these areas. In these instances we need to look at more than a few attributes as well as outside factors that can effect or decision. For example, Bluetooth tried to push into the WLAN space for Networking. It adopted a profile that supported TCP/IP and vendors developed access points. However, WLAN was already being deployed in the infrastructure and had better throughput and range – which were key attributes, so it won out and Bluetooth’s success in this area is very limited.
