Introduction The Ubitag V2.4 is a wireless device intended to be used for the real-time location of personnel and hand-held objects. It transmits ultra-wideband (UWB) pulses which are picked up by a network of basestations (Ubisensors) placed, 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 Ubitag, important regulatory information concerning its use, and details on how to diagnose potential problems. Information to the User The Ubitag V2.4 is an ultra-wideband (UWB) wireless device certified under FCC Part 15.519. Its use is subject to technical requirements for hand-held UWB systems. Users should note carefully the following information: ∑ 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. ∑ UWB devices operating under the provisions of this section must be hand held, i.e., they are relatively small devices that are primarily hand held while being operated and do not employ a fixed infrastructure. ∑ The use of antennas mounted on outdoor structures, e.g., antennas mounted on the outside of a building or on a telephone pole, or any fixed outdoors infrastructure is prohibited. Antennas may be mounted only on the hand held UWB device. Users should also carefully note the following information: ∑ CAUTION: Any changes or modifications made to the Ubitag which are not expressly approved by the Ubisense Limited could void the user's authority to operate the equipment. ∑ NOTE: 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. 2 Ubisense – Ultra-wideband In-Building Location System – Ubitag V2.4

Installation and Operation Instructions Switching the Ubitag on for the first time The Ubitag is supplied with a battery, which needs to be fitted prior to operating the tag. Fitting or replacing the batteries in the Ubitag The Ubitag uses a Panasonic CR2477 3V lithium coin cell (or equivalent). Ubitags frequently report their battery health to the system via the Ubisensors, so system administrators should be notified by the system when the battery in a particular tag requires replacement. To replace the battery in a Ubitag: 1. Unscrew the four screws in the back of the enclosure 2. Remove the PCB from the enclosure to allow access to the battery 3. Slide out the old battery and dispose of carefully 4. Replace the battery with a new one, being careful to observe correct polarity When the battery has been replaced, the Ubitag will bleep once…

LETTER OF EXPLANATION 05/25/2006 Federal Communications Commission Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 USA Subject: Ubisense Limited FCC ID: SEATAG21HH To Whom It May Concern: The attached application is for a device that is both a 6 to 8 GHz UWB operating under 15.519 and a 15.249 device operating in the band 2400 to 2483.5 MHz. The assembly consists of a handheld module with integral antennas. The whole device is powered by a 3Vdc coin type cell. Previously a similar device from this applicant was certified as a Part 15.517/15.249 composite device (FCC ID: SEATAG20), and we are again following the FCC’s guidance relating to that previous certification, which included submitting test reports for both the 15.517 and 15.249 transmitters under a single FCC ID. Should you have any questions or require any further information with regards to this, please feel free to contact me. Sincerely, Mario de Aranzeta C.E.T. Engineer

OPERATIONAL DESCRIPTION UBITAG7024 FCC ID: SEATAG21HH The UBITAG7024 is a wireless device intended to be used for the real-time location of personnel and hand-held objects. It transmits ultra-wideband (UWB) pulses which are picked up by a network of basestations (Ubisensors), allowing the 3D position of the tag to be found. The use of UWB technology enables greater positioning accuracy within buildings than other wireless technologies, because it is much less susceptible to multipath interference effects. Applications of the system include healthcare, workplace productivity, security and retail management. The UBITAG7024 is a composite device consisting of an ultra-wideband transmitter, a conventional radio transceiver operating in the range 2402.5-2480.5MHz, and associated digital circuitry. It is never the case that both the ultra-wideband transmitter section of the device and the conventional radio transceiver section of the device are active simultaneously. Both the ultra-wideband transmitter and the conventional radio transceiver utilise permanently attached antennas that are integral to the device. The UBITAG7024 will not transmit ultra-wideband signals unless it receives suitable trigger commands (over the range 2402.5-2480.5MHz conventional radio link) from an associated base station. It is programmed to cease transmissions within 10 seconds unless it receives an acknowledgement from an associated receiver that its UWB transmission is being received.

Declaration of maximum 2.4GHz link duty cycle for Ubitag V2.x devices Andy Ward Chief Technology Officer Ubisense Limited 1 June 2007 Overview This document describes the maximum possible duty cycle of transmissions of the Ubitag V2.0, V2.1, V2.2, V2.3 and V2.4 devices via their 2.4GHz transceivers, which are to be certified under FCC Part 15.249. Device operation As part of their operation, the Ubitag V2.0, V2.1, V2.2, V2.3 and V2.4 devices utilise a 2.4GHz conventional radio link which is to be certified under FCC Part 15.249. To maximise battery lifetime, these devices transmit only infrequently on the 2.4GHz radio link. The maximum time for which the 2.4GHz transmitter of the Ubitag devices may be active in a cycle is 4.6ms, and the maximum rate at which the device may be cycled is 44.5Hz, leading to a maximum transmitter on time of 4.6ms every 22.5ms. The maximum transmitter on time in any 100ms period is therefore 5 x 4.6ms = 23ms, because in the worst-case the 100ms window can happen to capture five complete 4.6ms transmission periods, each with a (22.5ms – 4.6ms) = 17.9ms gap between them. The plot below shows the conducted output from a Ubitag V2.0 device when it is transmitting at maximum duty cycle, across a worst-case 100ms span, and validates the numbers given above. The operating code and 2.4GHz transceivers on the V2.0, V2.1, V2.2, V2.3 and V2.4 Ubitags are identical, and therefore will generate identical results. Conclusion The maximum possible transmitter ‘on’ time of a Ubitag V2.0, V2.1, V2.2, V2.3 or V2.4 device is 23ms in any 100ms period .
