IrriWise ™ Wireless Crop Monitoring System IrriWise Transmitter IrriWise Transceiver (Receiver/Repeater) User Manual Miltel Communications Ltd. September 2004 1-2 CHAPTER 1 INTRODUCTION 1.1 GENERAL This chapter provides a functional description of the IrriWise TM – Wireless Crop Monitoring System. This system has been designed to provide the grower with real-time data collected from the field, thereby providing better control over irrigation scheduling and farm resources. 1.1.1 What Is The System Intended For? The IrriWise TM system is a management tool intended to provide the grower with better control over crop irrigation and farm resources by means of data collection and its interpretation. Data is collected from the field using state of the art radio technology and transferred to your PC, where it is presented in user-friendly software, enabling easy data interpretation, improving real-time decisions and analysis of history. Data is sampled from the sensors and transmitted to base station as follows: • Soil moisture sensors are measured every 15 minutes and transmitted every 30 minutes. • Weather station sensors are measured every 5 minutes and an average reading is transmitted every 15 minutes. • Water meter readings are sent at the beginning and end of irrigations and every 10 minutes during irrigation. 1-3 1.1.2 Wireless Crop Monitoring System Diagram A basic diagram of the Wireless Crop Monitoring System is displayed in Figure 1-1. Since the system is modular, different configurations and components are possible.

Wireless Crop Monitoring System Diagram 1-4 1.1.3 System Components The Wireless Crop Monitoring System is comprised of the following components: a. Wireless system: • Base station – PC, IrriWise Receiver (transceiver) and antenna • IrriWise Transmitters • IrriWise Repeater (transceiver) b. Radio Manager TM application – radio and network management software. c. IrriWise TM application – user-friendly graphing and data analysis software. d. IrriDial TM application – remote access dialer enabling data download from various IrriWise TM users. e. Sensors: • Gro-Point TM – a volumetric soil moisture sensor based on TDT technology with fast and accurate response to changes in soil moisture. • Tensiometer transducer – a special transducer that enables accurate and reliable measurement of most traditional tensiometers. • Weather station (up to 8 different sensors) – a fully modular weather station for measuring the local microclimate. Supports the following sensors: air temperature, relative humidity, solar radiation, wind speed, wind direction, rain gauge, leaf wetness and soil temperature. Transmits calculated data such as ET, dew point and gust. The rain gauge can be installed as a standalone unit independent of the weather station. • Water meter – various types of water meters: • Lateral or mainline flow meter – standard pulse-type flow meters. • 1/2” drip-line flow meter to record single drip-line irrigation volume and runtime. • Fertilizer flow meter can be connected to the system to record when and how much fertilizer has been applied. 1-5 • Tipping bucket flow sensor to record irrigation volume and runtime based on individual dripper. 1.1.3.1 Wireless System The wireless system provides the remote access interface. The transmission range of the wireless system is up to 4 km (2.5 miles), depending on the following factors: a. Interference (noise) on the selected frequency. The “cleaner” the frequency, the longer the range. b. Crop clearance – radio waves do not penetrate foliage very well, especially when wet from rain or dew. c. Topographical conditions – the extent of line of sight (LOS) pureness and positioning height affect the transmission range accordingly. Base Station Receiver and Antenna The base station includes the antenna and receiver as a joint unit and is responsible for the reception of data sent by the transmitters and for its transfer to the PC via RS232 (see Figure 1-2). 1-6 Antenna Re c e i v e r RS2 3 2 a n d Po w e r Su p p l y Output to PC Input From Ante nna Rear Connection to Pole Figure 1-2.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 November 24, 2004 RE: Miltel Communications Ltd. FCC ID: MLLIWCRPT15-17 After a review of the submitted information, I have a few comments on the above referenced Application. 1) The internal photographs may not normally be held confidential strictly on the basis of trade secrets. Please remove this justification from the letter of confidentiality or provide a better justification. As an alternative, you may use a black marker to "black out" the top of any readable components and provide new internal photographs. Please let us know how you wish to proceed with this issue. 2) It is not clear how this behaves as a repeater. Is the information down converted? Does the TX rebroadcast any information it the 150-170 MHz band, or does it only re-broadcast information it is capable of de-modulating? Please provide further information for this mode of operation and clarify if this device is a booster or repeater. These are defined as follow: Booster is a device that automatically reradiates signals from base transmitters without channel translation, for the purpose of improving the reliability of existing service by increasing the signal strength in dead spots. An “in-building radiation system” is a signal booster. These devices are not intended to extend the size of coverage from the originating base station. A booster can be either single or multiple channels. Repeater is a device that retransmits the signals of other stations. Repeaters are different from boosters in that they can include frequency translation and can extend coverage beyond the design of the original base station. A repeater is typically single channel but can also be multiple channels. 3) If this is device considered a single channel (Class A) or multi channel (Class B) repeater/booster? Signal booster. A device at a fixed location which automatically receives, amplifies, and retransmits on a one-way or two-way basis, the signals received from base, fixed, mobile, and portable stations, with no change in frequency or authorized bandwidth. A signal booster may be either narrowband (Class A), in which case the booster amplifies only those discrete frequencies intended to be retransmitted, or broadband (Class B), in which case all signals within the passband of the signal booster filter are amplified. Depending on its classification, was the appropriate testing performed for intermodulation? 4) Please see attached guidelines for amps, repeaters, boosters. Please make sure all appropriate guidelines are followed. 5) In repeater mode of operation, please explain how the device performs power leveling. How does the output signal vary as a function of input signal level? 6) For purposes of testing, how does the device generate an output signal. If a input signal was required, how was a input level determined. Please provide further information (i.e. explain the alternative signal used). --- Continue on Next Page --- z Page 2 November 30, 2004 7) Normally for testing the emissions bandwidth of amplifiers, boosters, repeaters, the input signal is compared to the output signal. This does not appear to have been performed this way. Please explain. 8) Please provide information regarding the antennas used with the system. 9) Please provide RF exposure information for this device. 10) Please consider adding information to the users manual regarding licensing requirements. Examples of this are: The equipment user is required by the radio service rules to obtain a license before operating the equipment. Licensing of this equipment is the user’s responsibility, and licensability depends on the user’s classification and application, and on the selected frequency. The user is strongly urged to contact the appropriate telecommunications authority concerning proper licensing, and before choosing and ordering frequencies. 11) Please explain the reference level settings for plots 7.3.1 – 7.3.3 and 7.5.1 – 7.5.6. Is this the unmodulated output power. Normally a second unmodulated plot is also shown on the same plot to show the to equal the reference line level. If so, please explain why the reference levels between the 2 sets of plots do not match. 12) Please explain why the carrier is so low in plots 7.4.7 – 7.4.9. Was the antenna terminated for this test? 13) It is uncertain why the emission designator for this device is only 5K85F1D. It is assumed that it will rebroadcast emission received from FCC ID MLLIWCTX15-17 which has emission designator 12K5F1D. Timothy R. Johnson Examining Engineer mailto: [email protected] The items indicated above must be submitted before processing can continue on the above referenced application.

Hello Tim, Please find below our replies to your comments. 1) Please find attached the new set of internal photographs. 2) The transceiver completely demodulates the received messages as explained in the attached Repeater Operation description and shown in the attached block diagram. Upon this there is no change in the transmitted RF signal associated with transceiver mode of operation. 3) The same as 2). 4) The same as 2). 5) The same as 2). 6) The same as 2). 7) The same as 2). 8) Please refer to the attached document . 9) RF exposure was not evaluated as the RF output power does not exceed 1.5W as provided in section 2.1091(c) of the FCC rules. 10) Please refer to the last page of the attached user manual. 11) The reference level shown in plots 7.3.1-7.3.3 and 7.5.1-7.5.6 was adjusted to the total power of the transmitter in both cases. The difference in the reference level settings was caused by slightly different set ups (external attenuator, RF cable, spectrum analyzer) and as both of the measurements are relative no corrections were applied. 12) Radiated spurious emissions were tested with RF antenna connector terminated with 50 Ohm dummy load. 13) The device use FSK modulation with the maximum frequency deviation +/- 3 kHz and the highest modulating frequency +/- 2.4 kHz. Upon this the necessary emission bandwidth is 2*(3.0+2.4)=10.8 kHz and the correct emission designator is 10K8F1D. Best regards. Michael Nikishin.
