2. Description
The SiteWERX Location system consists of System Management software residing
on a networked PC, a SiteWERX Base Station (SBS), and one or more SiteWERX
Location Nodes (SLN’s).
The SBS and SLN’s form a communication chain (scatter-net) using Bluetooth radios.
The SBS uses Ethernet or 802.11 Wi-Fi 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) software are able to communicate with an SLN to receive location and real-
time messages, reference Figure 1.
Figure 1 SiteWERX Location System
2.1 SiteWERX Base Station
The SBS has the following functional capabilities:
a) Operate as a Bluetooth device in accordance with the Bluetooth 2.0 + EDR
b) Establish wireless links with other Bluetooth devices in proximities of 1 to 10
meters
c) Transmit area-specific information to other Bluetooth devices in support of
precision location
d) Transmit information to, and receive information from other Bluetooth devices in support of
system administration, status and diagnostics
e) Transmit Real-Time Alerts
f) Establish Ethernet or 802.11 link with System Management Console

2.2.3 Voltage and Operating Current
The SBS module operates with an input of 3.3 VDC and a max current ≤ 700 mA .
2.2.4 Antennas
The SBS Module has two identical antennas. One for the transmission and reception
of Bluetooth Radio-Frequency (RF) Signals, and one for the transmission and
reception of WI-FI Radio-Frequency (RF) Signals.
The antennas are 4 inch dipoles with 50 ohm impedance, and a typical gain of 2.0
dBi, Figure 3.
The SBS antennas are capable of transmitting a constant 1.0 watt.
The SBS antennas have a right angle, reverse polarity SMA connector.
The SBS antennas are adjustable and normally operate with the primary axis aligned
with the local vertical.

2.2.5 Power Supply
The SBS module operates from an external AC/DC power supply to provide a
regulated DC voltage of 3.3 VDC at 2.18 Amps, and consumes a maximum of 7.2
Watts.
2.2.6 Power-On Indicator
The SBS has a GREEN LED indicator that is illuminated when power is enabled.
2.2.7 Development/Programming Interface
The SBS has a four-wire serial peripheral interface (SPI). The SPI is used for real-
time debugging / development, and is connected to a PC parallel or USB port via
connector and cable assembly made by WirelessWERX.
The development / programming interface is designed to permit the following
connections:
PC connect to LAN module only
PC connect to Bluetooth module only
Bluetooth module to LAN module, No connection to PC
2.3 Construction and Packaging
The SBS modules, and related circuit elements are assembled on a single PCB. The
PCB shall be enclosed in a Bud Industries Plastibox, PT-11754, with the following
(nominal) dimensions:
Length 4 inches
Width 5.5 inches
Height 1.5 inches
The SBS Bluetooth module RF output is brought to the edge of the PCB and
terminated in bulkhead type, SMA connector that penetrates the enclosure and
permits the connect/disconnect of the SBS antenna external to the enclosure.
The SBS Wi-Fi module RF output is brought to the back panel of the enclosure with
50 ohm coax cable terminated in an SMA connector that penetrates the enclosure
and permits the connect/disconnect of the SBS antenna external to the enclosure.
