UtiliNet® Endpoint User Guide 11-1-2006 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 11-1-2006 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 Chapter 3 11-1-2006 UtiliNet Endpoint Configuration A local UtiliNet radio is required to communicate with the integrated UtiliNet radio modules inside your meters. This radio may be a standard UtiliNet Series 3000 IWR radio as seen below. Connecting to a radio Open RadioShop on your computer. Connect your local radio’s Lan Packet Protocol serial port to your computers serial port.
UtiliNet® Endpoint User Guide 11-1-2006 Adding new Radios to RadioShop You will now need to add the meter radios to the RadioShop database. This is be done by invoking the automatic discovery feature from the Radioshop main menu. Make sure your local radio is highlighted in the network view and select Utilities>>Radio>>Discover Neighbors from the RadioShop main menu.
UtiliNet® Endpoint User Guide 11-1-2006 Setting the Latitude and Longitude In order to give your device a fixed Latitude and Longitude you must first specify the meter module as a “non-mobile” device. Do this by selecting Configure>>Send DCW from the main menu and selecting the UMOBILE.HEX DCW. Once sent confirmation should be displayed on a “DCW Response” tab as shown below. Next you will have to set up a Latitude and Longitude or "”WAN Address” for your integrated meter module.
UtiliNet® Endpoint User Guide 11-1-2006 value. You may accept the default parameters for the protocol settings or change these to match your networks protocol settings if known. Now you will be able to configure the radio to be a member of your new network. Select Configure>>Radio from the RadioShop main menu. Select the default radio configuration file and the new network you would like the radio to be a member of and click OK.
UtiliNet® Endpoint User Guide 11-1-2006 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. For more information on UtiliNet module configuration, transparent port configuration, and routing configuration see the UtiliNet Technical Reference Guide.
UtiliNet® Endpoint User Guide 11-1-2006 Line-Of-Sight Like traditional radios, UtiliNet radios operate in the 900 MHz range of the radio frequency spectrum and, therefore, fall into a class of communications equipment referred to as line-of-sight. As a general rule of thumb, line-of-sight communications equipment requires a clear, unobstructed view from the source radio to the destination radio in order for communications between the two to occur.
UtiliNet® Endpoint User Guide 11-1-2006 in a logical way, it is not necessarily important that the lat/long coordinates be physically accurate. What is important, is that the lat/long coordinates of each radio be relatively correct to one another. In other words, if each radio in a particular network was programmed with the same distance offset from the actual physical location, network routing would not be adversely affected.
UtiliNet® Endpoint User Guide 11-1-2006 algorithms. • In addition to the geographical information, USGS maps provide topological information that is helpful when planning and maintaining a UtiliNet network. If the network is installed in an area with high ridges and low valleys, USGS maps can be used to determine potential trouble areas as well as ideal repeater sites. • Maps also provide an excellent graphical representation of the network.
UtiliNet® Endpoint User Guide 11-1-2006 Radio Link Budget Link Budget is a term used to describe a radio link from transmitter to receiver, and all of the factors in between. Link budget analysis uses a simple method of allocating appropriate factors to each portion of the link and then algebraically adding these factors. Then, the proposed link can be evaluated by how many dB’s are left over. To analyze link budget, you must look at each component of the communication system.
UtiliNet® Endpoint User Guide 11-1-2006 The total path loss if highly variable and can be estimated by: • Field propagation measurements—This can provide the most valuable data, but these results can still vary from one time to another time. • CAD tools based on various models—Some models tend to overestimate path loss; some models tend to underestimate path loss.
UtiliNet® Endpoint User Guide 11-1-2006 hill or water tank, the terrain is considered relatively flat. The path loss adder term is -10 dB at 915 MHz, according to the Okumura/Hata propagation prediction method using the suburban area model. Receiver Antenna The previously mentioned antenna considerations also apply here, including possible ground plane effects. For this example, this is (again) a “3 dB omni-directional.
UtiliNet® Endpoint User Guide 11-1-2006 Table 3.2 Multipath vs. Percent Coverage Margin of Safety Radio systems are usually not designed to operate precisely at threshold, or even at threshold plus the multipath factor. Usually they are designed with some extra margin. This is called a margin of safety, and is used to account for long-term variance in the received signal level. A value of 0 to 35 dB is suggested—the actual number depends on how conservative you are. You will use 5 dB for this example.
UtiliNet® Endpoint User Guide 11-1-2006 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 11-1-2006 • 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 11-1-2006 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 11-1-2006 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 11-1-2006 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 11-1-2006 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.
