UtiliNet® Endpoint User Guide 1-5-2007 Network of Intelligent Radios UtiliNet radios form the foundation of a UtiliNet network and serve multiple functions. • Each radio can communicate to end devices for some data collection or control function. • This may involve transparent applications where data is merely passed through UtiliNet radios, or it may involve programs running in radios and/or other gateway devices to perform custom applications, higher network efficiency or enhanced functionality.
UtiliNet® Endpoint User Guide 1-5-2007 Radios With Programmable Intelligence Each radio is similar to a programmable logic controller (PLC). The radio acts much like a small computer, carrying out any number of computing and command functions. The intelligence in each radio enables it to perform many functions not normally associated with radios such as making intelligent routing decisions, transporting industry protocols, and recognizing operating conditions and responding with pre-programmed logic.

UtiliNet® Endpoint User Guide 1-5-2007 Endpoint Antenna Configurations L&G Focus-2 Utilinet Endpoint Antenna: This device has been designed with an integrated loop antenna, located on the PCB surface layer on the reverse (non-component) side of the assembly. This antenna has a typical gain of 3 dB. GE I-210 Utilinet Endpoint Antenna: This device has been designed with an integrated loop antenna, located on the PCB surface layer on the reverse (non-component) side of the assembly.
UtiliNet® Endpoint User Guide 1-5-2007 Open RadioShop on your computer. Connect your local radio’s Lan Packet Protocol serial port to your computers serial port. Select Communications>>Connect from the RadioShop main menu making sure you select the right Com port and a Baud rate. The default baud rate for UtiliNet radios is 9600 bps. When you are connected to the local radio, a Radio Configuration Report will be executed automatically and displayed.
UtiliNet® Endpoint User Guide 1-5-2007 Communicating with integrated meter modules In order to address a remote endpoint that has not been configured with a Latitude/Longitude you must select the endpoint “via” your local radio. This tells the network what path to take to reach the endpoint, which does not yet have a valid Latitude/Longitude. To select your endpoint “via” your local radio, right click on the endpoint and select “Select Via…” from the context menu.
UtiliNet® Endpoint User Guide 1-5-2007 Updating the Network ID (CRC Adder) In order to configure your integrated meter module with your company’s unique network ID or CRC Adder you must first add a network to RadioShop with your company’s network ID. Select Utilities>>Network>>Add Network from the RadioShop main menu to access the “Add Network” screen. Name the network and specify the network ID (CRC Adder) to your company’s assigned value.
UtiliNet® Endpoint User Guide 1-5-2007 the new network you would like the radio to be a member of and click OK. The radio will be automatically moved to the destination network and updated with the destination network’s network ID. Note UtiliNet radios may only communicate on one network at a time. You will not be able to communicate to the integrated meter radio over-the-air until you move your locally connected radio to the same network.
UtiliNet® Endpoint User Guide 1-5-2007 Traditional Radio Comparisons Much of the work involved in the layout of a traditional voice or analog radio network deals with its variability and uncertainties. Its design can be quite complex. This is simply the nature of analog technology. Digital radio, however, is different. System designers with a background in analog radio may find installing a UtiliNet system to be somewhat simplistic.
UtiliNet® Endpoint User Guide 3. 4. 5. 1-5-2007 aesthetics. In the 900 MHz frequency band, antenna height provides the largest gain in terms of RF distance. In general, the higher that antennas may be mounted the better. Use topographical maps or computer prediction programs to plot paths between known nodes to get an indication of the ability of radios to communicate with one another over the average terrain in the area.
UtiliNet® Endpoint User Guide 1-5-2007 Repeatability of the GPS information has proven to be less than ideal. Readings taken from the same physical location at different times of the day tend to vary significantly (often more than the specified +/300 meters). As mentioned earlier, it is most important that the radios’ lat/long coordinates be RELATIVELY correct to one another. Using a GPS may compromise the repeatability of relatively correct readings. The user may want to occasionally verify the GPS.

UtiliNet® Endpoint User Guide 1-5-2007 When a ground plane is required, but is not large enough, effective gain reduction results. If applicable, a reduction of 1 to 2 dB on antenna gain would be in order for ground planes smaller than about 6 to 8 inches along the narrowest axis. Transmitter Transmission Line Loss This is the equivalent cable loss of any transmission line that might be used to mount an antenna remotely from the radio assembly.
UtiliNet® Endpoint User Guide 1-5-2007 along the path, distance, and other parameters can determine this factor. Typically, this factor ranges from 5 to 40 dB. This factor, plus the free space path loss, gives total median path loss. Example: Assume a path that is 5 miles long. One antenna is on a hill or water tank 300 ft. higher than the surrounding area. The other antenna is on a 30 ft. support structure, for example on the rooftop of a 1 story building. Except for the Table 3.
UtiliNet® Endpoint User Guide 1-5-2007 For most receive signal measurements, slight changes of antenna location (on the order of 1 wavelength), or measurements at different times, will show a short-term variance of received signal level. This is generally due to multipath. An allowance of approximately 8 dB should be made on most radio links at 915 MHz.
UtiliNet® Endpoint User Guide 1-5-2007 It is apparent that this link of 5 miles distance, under the conditions described, should be very reliable because you were able to include a conservative multipath factor and a margin of safety, and still have the link budget balance. If the end application allows links with less than ideal margin and reliability, much larger distances may be spanned.
UtiliNet® Endpoint User Guide 1-5-2007 • Power consumption versus dynamic range • Size versus dynamic range • Cost versus dynamic range Currently, all UtiliNet products have a receive sensitivity of about -107 to -112 dBm, with an allowable single-tone interference level of around -20 dBm before sensitivity reduction takes place. Thus, the dynamic range is about 90 dB.
UtiliNet® Endpoint User Guide 1-5-2007 sites. Most UtiliNet surveys are accomplished by temporarily installing a UtiliNet radio at the master site or at a repeater site and testing connectivity from the master or repeater to the remote sites in the predicted coverage area of the master or repeater. One of the advantages to spread spectrum technology is the license-free operation that allows installation anytime and anywhere.
UtiliNet® Endpoint User Guide 1-5-2007 Glossary Accumulator An accumulator is simply a counter in an RTU that records the number of times a contact opens and closes or in the case of a form C contact, records the number of transitions from one contact to the other (K to Y then K to Z in the meter world). Accumulators are most often used as interfaces into metered values. Each accumulated pulse represents some metered quantity (KWH, gallons, barrels, etc.).
UtiliNet® Endpoint User Guide 1-5-2007 radio qualifies as in the same domain of the packet destination if it has the same color and its geographic location lies within the domain qualifying radius of the final destination. During a domain cul-de-sac, a core radio that sees a domain of the same color qualifies as seeing the correct domain if it is within this distance of the final destination. Domain Radio In a network using domain routing, radios are divided into “core” and “domain” radios.
UtiliNet® Endpoint User Guide 1-5-2007 Bit 1: L3_MOOD_RELIABLE Bit 0: L3_MOOD_SCRAM (not supported) Multipoint Radios Multipoint radios are radios that may initiate data to multiple destination addresses. Packet Parameters The parameters in a packet that control the routing, processing, and limitations of its transmittal. The four packet parameters are mood, priority, luck, and time-to-live.
