2. Description
The SiteWERX Location system consists of System Management software residing
on a networked PC, a Base Station, and one or more SiteWERX Location Nodes
(SLN’s), Figure 1.
The Base Station and SLN’s form a communication chain (scatternet) using Bluetooth
radios. The Base Station maintains a communication link with the Management
Console, allowing the system to be managed by a PC. 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

2.1 SiteWERX Location Node (SLN)
The SLN has the following functional capabilities.
a) Operates as a Bluetooth device in accordance with the Bluetooth 2.0 + EDR
b) Establishes wireless links with other Bluetooth devices in proximities of 1 to 10
meters
c) Transmits area-specific information to other Bluetooth devices in support of
precision location
d) Transmits and receives information to and from other Bluetooth devices in support of
system administration, status and diagnostics, and alarm/alert situations.
2.1.1 Architecture
The SiteWERX Location Node module consists of a Bluetooth Module for Bluetooth
operations, an antenna, and a voltage regulator. A functional block diagram of the
SiteWERX Location Node is shown in Figure 2

2.1.3 Operating Voltage and Current
The SLN is connected to a power distribution network powered by an AC/DC
converter.
The SLN operates with an input of 6 to 15 volts DC, and has a maximum operating
current of ≤ 0.070 Amps.
A voltage regulator provides 3.3 volts DC to the Bluetooth module

2.1.4 Antenna
The SLN has an embedded dipole antenna for the transmission and reception of
Bluetooth Radio-Frequency (RF) Signals. The antenna is an Antenna Factor chip
antenna, ANT-2.45-CHP-x. The antenna physical dimensions are shown in Figure 3.
The radiation pattern is shown in Figure 4.
The antenna has linear polarization, a 50 ohm input impedance, and is capable of
transmitting a continuous output of ≥3 watts.

2.1.5 Development/Programming Interface
The SLN is programmed using a dedicated four-wire serial peripheral interface (SPI).
The SPI is also used for real-time debugging / development, and is connected to a
PC parallel port via connector and cable assembly made by WirelessWERX.
2.1.6 Status Indicators
The SLN has two LED status indicators. One RED LED is illuminated when power is
on. A second GREEN LED is illuminated when the Network status is positive.
2.1.7 Enclosure
The SLN assembly consists of a PCB mounted in an enclosure 3.0” x 2.5” x 1.5’’.
The enclosure material is Polylac-747, an ABS. The enclosure wall thickness is as
thin as practical to minimize Radio Frequency signal attenuation and reflections.
2.1.8 Environment
The SLN allowable environments for operating and storage are as follows:
Operating Temperature
-40 to +70 C
Storage Temperature
-40 to +85 C
Operating Humidity
SiteWERX
5% to 80% RH, non-condensing

3. Constraints
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference and
(2) this device must accept any interference received, including interference that
may cause undesired operation.
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.
