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.

2.2.2 WI-FI Module
The SBS-W has a WI-FI Module to provide the operating parameters and protocols
required by the IEEE 802.11 b/g wireless standard.
2.2.2.1 Radio Characteristics
Receiver Typical Data Rate
Sensitivity @ 0.1% BER - 69 dBm 54 Mbps
- 88 dBm 11 Mbps
- 91 dBm 1.0 Mbps
Transmitter Typical Unit
RF Transmit Power 11 to 16 dBm
Data Rates 1, 2, 5.5, 11, 6, 9, 12, 18, 24, 36, 48, 54 Mbps
2.2.3 Voltage and Operating Current
The SBS-W module operates with an input of 3.3 VDC and a max current ≤700 mA .
2.2.4 Antenna
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 a 50 ohm impedance, and a max gain of 2.89
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-W 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 power of
7.2 Watts.
2.2.6 Power-On Indicator
The SBS has a RED LED indicator that is illuminated when power is enabled.

3. Constraints
Instruction to the User
This equipment has been tested and found to comply with the limits for a class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
* Reorient or relocate the receiving antenna.
* Increase the separation between the equipment and receiver.
* Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
* Consult the dealer or an experienced radio/TV technician for help.
Operation with non-approved equipment is likely to result in interference to radio and TV
reception. The user is cautioned that changes and modifications made to the equipment
without the approval of manufacturer could void the user's authority to operate this
equipment.
