Introduction The Ubisensor V2.0 is a basestation used by the Ubisense Location System, which supports the real-time location of objects. It detects ultra-wideband (UWB) pulses emitted by wireless tags (Ubitags), allowing the 3D position of the tag to be found. The use of UWB technology enables greater positioning accuracy than other wireless technologies, because it is much less susceptible to multipath interference effects. Applications of the system include healthcare, workplace productivity, security, retail management and manufacturing. This document describes the features and specifications of the Ubisensor, important regulatory information concerning its use, and details on how to diagnose potential problems. Information to the User The Ubisensor V2.0 contains a wireless transceiver certified under FCC Part 15.249. 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. NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. CAUTION: Any changes or modifications made to the Ubisensor which are not expressly approved by Ubisense Limited could void the user's authority to operate the equipment.

Features of the Ubisensor The diagrams below show several important features of the Ubisensor: Status LED Timing cable sockets Ventilation holes Networking socket MAC address (ID) label Power Supply Socket Ubisense – Ultra-wideband Location System – Ubisensor V2.0
Installation and Operation Instructions Mounting options Ubisensors have three mounting holes in the back of the case, to which external clamps and brackets can be attached. Two holes are M4 size, the other hole is M6 size (and can be used in conjunction with a standard photographic camera mount). Setting up a sensor cell Ubisense will have supplied you with an updated location system database containing configuration information for the equipment you have received. At this point, it’s worth checking that the MAC (Media Access Control) addresses of the Ubisensors you have received match the information in the database, using the Ubisense location system configuration tools. See the software manual for details on how to examine the contents of the configuration database – the MAC address for each Ubisensor is printed on a label affixed to the rear of the unit (see “Features of the Ubisensor”). Once you are sure you have the correct equipment to hand, the sensor cells for the system can be set up. In the Ubisense location system, a large area of space is covered by a number of sensor cells, each of which (individually) covers a smaller area. Each sensor cell has a master unit and number of slave units (usually three or more). The information provided by the Ubisense location system configuration tools will let you identify, for any particular sensor cell, which unit is the master and which are slaves, using the MAC addresses of the devices. The master unit in each sensor cell generates a timing signal which is used by the slave units of that cell. The master unit is connected to the slave units using shielded Category 5e cable (or better). A timing cable from the master to a slave can be plugged into any free timing socket on the master, but must be plugged into the top right…

Declaration of maximum 2.4GHz link duty cycle for Ubisensor V2.0 Andy Ward Chief Technology Officer Ubisense Limited 4th June 2007 Overview This document describes the maximum possible duty cycle of transmissions of the Ubisensor v2.0 device via its 2.4GHz transceiver, which is to be certified under FCC Part 15.249. Device operation As part of its operation, the Ubisensor V2.0 device utilises a 2.4GHz conventional radio link which is to be certified under FCC Part 15.249. The device transmits only infrequently on the 2.4GHz radio link. The maximum time for which the 2.4GHz transmitter of the Ubisensor may be active in a cycle is 2.2035ms, and the maximum rate at which the device may be cycled is 160Hz, leading to a maximum transmitter ‘on’ time of 2.2035ms every 6.25ms. The maximum transmitter ‘on’ time in any 100ms period is therefore 16 x 2.2035ms = 35.256ms. Conclusion The maximum possible transmitter on time of a sensor is 35.256ms in any 100ms period. Therefore the duty cycle correction factor which should be applied to measurements of a continuous signal during testing = 20log(35.256/100) = -9.055 dB

It detects ultra-wideband (UWB) pulses emitted by wireless tags (Ubitags), allowing the 3D position of the tag to be found. The use of UWB technology enables greater positioning accuracy than other wireless technologies, because it is much less susceptible to multipath interference effects. Applications of the system include healthcare, workplace productivity, security, retail management and manufacturing. The Ubisensor V2.0 is a composite device consisting of a conventional FM radio transceiver operating in the range 2400-2483.5MHz (FCC ID SEASENSOR20, which is subject to certification, the application for which is supported by this document), and an associated Class A digital device (which will be subject to Verification Authorisation under section 15.101b of CFR47). The conventional FM intentional radiator section of the device utilises two antennas for the purposes of antenna diversity. Both antennas are permanently attached and are integral to the device.

This device is a basestation for a precision location system. It is considered to be a composite device consisting of: oa transceiver operating in the 2402.5-2480.5MHz region (and its associated control circuitry) oa ultrawideband receiver (contained within the transceiver circuit) oa Class A digital device The transmitter section of the 2402.5-2480.5MHz transceiver is subject to Certification Authorisation. The Class A digital device, the ultrawideband receiver, and the receiver section of the 2402.5-2480.5MHz transceiver are subject to Verification Authorisation (see section 15.101b of CFR 47). For the purposes of testing, the Ubisensor was considered as an intentional radiator operating under the rules of section 15.249 of CFR 47. Conducted emissions were measured from the transmitter circuit, the wideband receiver and the active parts of the digital device. Details of the EUT and associated peripherals used during the tests are listed below. Figure 1 shows the interconnections between the EUT and peripherals.
