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.
Driving standards: We are a promoter company of the ZigBee Alliance (only 6 total) and a driving member of the IEEE 802.15.4 standard. Our PHY (physical layer) was chosen as the standard, and our MAC (media access control) was a joint proposal with Philips (we wrote the spec). Motorolans have also authored and co-authored technical articles, white papers, and even two books. We are regarded as the technical experts on the technology and recognized as paving the way for the standard. First to market: We were the first to demonstrate 802.15.4 and ZigBee technology in June of 03. We are not on our first generation like other customers. We have already sampled to our alpha customers and they are already developing with our solution. Superior performance: Our RF data modem is the only IC to truly achieve -94 dBm receiver sensitivity, well above specification at -85 dBm, on-chip voltage regulation, improved adjacent channel rejection, and adjustable output power transmission.
