It is designed primarily for broadcasting low-latency differential GPS (DGPS) corrections or raw GPS data from a roving receiver (machine) to a repeater or reference station receiver, for use during real-time differential and real-time kinematic (RTK) surveying. 1.1TC900 Rovers as part of a TRIMCOMM 900 Network To achieve line-of-sight (LOS) coverage to all points in a work area, a TRIMCOMM 900 network including up to four repeaters must be used. The repeaters retransmit data packets according to a simple time-sharing scheme to avoid mutual interference. The operation of the repeaters is transparent to the TC900 rovers. This means that a TC900 rover can move around and pick up data packets from the reference station or any repeater, whichever it hears first. The reference, rovers, and repeater radios in a TRIMCOMM …

Correspondence Reference Number: 11012 731 Confirmation Number:EA95581 Date of Original E-Mail:12/13/1999 1) Please provide information showing compliance with the RF safety requirements. Submit the information in a separate exhibit and place it in the RF exposure info folder when submitting it. ANS: Refer to separate Word attachment: RF Hazard Please note: A new antenna by MaxRad has been added to those already tested and submitted. Radiated emissions data, antenna description, and manufacturer data sheets are being uploaded to FCC. 2) Please provide a confidential letter. ANS: Confidentiality letter is separate Word attachment: 900IPconf 3) You indicate the use of a unique connector. What is the type of unique connector being used? ANS: This is a Trimble proprietary connector that has been used on 900 MHz radios for several years. Refer to separate .jpg attachments titled: Unique 4) What is the receiver input bandwidth? ANS: 902 – 908 MHz– see page 1 of Theory of Operations, in separate Word document TCOM900_theory_of_op.doc 5) Provide a few samples of the pseudorandom hopping sequence. ANS: Refer to separate Word attachment: HOPPINGSEQ 6) The maximum allowed 20 dB bandwidth is 500 kHz. The device does not comply. Please explain. ANS: There was an error in setting the maximum and determining the 20 dB down points in the original test set-up. Refer to separate .jpg attachments named New20dB 7) The channel frequencies have to be separated by the greater of 25 kHz or the 20 dB Bandwidth of the hopping channel. Indicate compliance with this rule. ANS: Per 15.247a1, the hopping channels must be separated by at least 25 kHz or at least the channel BW, whichever of the two is greater. The channel BW is around 460 kHz. The channels are separated by 509.524 kHz – see page 1 of Theory of Operations, in separate Word document TCOM900_theory_of_op.doc 8) The transmitter cannot coordinate its hopping sequence with the hopping sequence of other transmitters, or vice versa, for the purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters. Provide a description on how the device complies with this rule. ANS: All transmitters in a network share the same synchronized hopping pattern. They do not avoid simultaneous occupancy, they guarantee simultaneous occupancy! If multiple transmitters transmit at thesame time, they will collide. A link-layer protocol uses TDMA to eliminate most simultaneous transmissions. Transmitters in separate networks are totally un-coordinated. 9) Each frequency must be used equally on the average by each transmitter. Except for voice systems, each new transmission must start at a different point in the sequence so that on average the full sequence is used. Therefore, Describe where the next transmission starts when all frequencies are not used for a previous message. This is required because some transmissions may need only a few frequency hops to be completed. i.e. If the transmission started on the same frequency each time, this frequency would be used more than the others if many short transmissions were sent. ANS: The hopping sequence is never re-started short of completion. It runs continuously, even if there is nothing to transmit. When there is something to transmit, it is transmitted using whatever part of the sequence is current.

Question:Do the antennas require a ground plane? Answer:Yes. The standard MLPV antennas require a ground plane. Question:How do these antennas compare with quarter wave antennas? Answer:MAXRAD MLPV antennas outperform any quarter wave antenna. Maximum performance can still be achieved with a traditional MAXRAD 5 dB gain mobile antenna.

ADDITIONAL INFORMATION RE: MAXRAD ANTENNA The antenna is manufactured by MaxRad and is described as a low profile vertical antenna. Their standard part number for this antenna is MLPV800, covering the frequency range of 806 to 960 MHz. Trimble’s antenna is a modified MLPV800, modified at the base so that it will mate properly to the TC900 antenna connector. The MaxRad part number for this Trimble antenna is Z661. The antenna consists of a brass vertical post and a brass disk at the top of the post. MaxRad has measured the antenna gain on the TC900 antenna mounting endcap and measured a peak gain of 2.3 dBi at 915 MHz.

Trimble 900IP RF Hazard RF Hazard Information Per Sec. 1.1307 For transmitters operating in the 902-928 MHz frequency range, paragraph 1.1310 limits maximum permissible exposure (MPE) to f/1500 mW/cm2 for uncontrolled environments and f/300 mW/cm2 for controlled environments. The maximum distance from the antenna at which MPE is met or exceeded is calculated from the equation relating field strength in V/m, transmit power in watts, transmit antenna gain, and separation distance in meters: E,V/m = (√(30*P*G))/d Power density, mW/m2 = E 2 /3770 E for MPE : √((902/1500)*3770) = 47.6 V/m Simplifying and rearranging terms: d = (√(30*P*G))/47.6 Converting to decibels: 20 log d = 10 log 30 + 10 log P watts + G dBi –33.6 dB 20 log d = 14.77dB + PdBm - 30 dB –33.6 dB + GdBi 20 log d = P dBm + G dBi –48.8 ; d = 10^(PdBm+GdBi-48.8)/20 Worst-case assumption is for 0.61 mW/cm2 uncontrolled environment: Max RF Output Power: 28.7 dBm Antenna TypeGain, dBiMPE distance, cm Short whip09.8 MaxRad2.312.9 Single coil517.6 Double coil722.1 The Trimble 900IP is designed to be mounted on a surveyor’s tripod or on the fender or roof of large vehicles such as earthmovers, bull dozers, dump trucks, and the like. The radio uses a single antenna, and is designed to operate in open spaces, and certainly at distances greater than 20 cm from equipment operators, bystanders, and radio users. Instructions will be placed in the user manual instructing installers and users to maintain the MPE distances during operation of the EUT: Trimble 900IP RF Hazard NOTICE: During transmiiter operation, a minimum distance of 22 cm (9 in.) shall be maintained between the antenna and personnel, in order to meet the maximum permissible exposure (MPE) limits in section 1.1310 of FCC Rules.
