2. Description
The SiteWERX Location system consists of System Management software residing
on a networked PC, a Bluetooth / WIFI Base Station, and one or more SiteWERX
Location Nodes (SLN’s).
The SBS-W and SLN’s form a communication chain (scatternet) using Bluetooth
radios. The SBS-W uses an 802.11 WIFI module to maintain a communication link
with a local area network, allowing the system to be managed by a PC with access to
this LAN. Mobile devices, such as cell phones and PDAs, running the SiteWERX
Mobile Client (SMC) are able to communicate with an SLN to receive location and
real-time messages, reference Figure 1.
