UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 Chapter 1 Introduction This manual provides technical information for the line of radios used in the UtiliNet® Wireless System. Included are photos, specifications, diagrams, and accessories for each radio type as well as detailed information on applications using the radios and other related information.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 the best paths if RF conditions change. Once configured by the user, radios automatically acquire radios and route packets. Each radio can execute one or more programs written in the Device Control Word (DCW) language. These programs can send, receive, and process packets to and from other radios. They also are able to send, receive, and process data to and from end devices connected to the radio.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 tomultipoint network). Further, most traditional network topologies poll, gathering data sequentially. UtiliNet radios can be programmed to respond under predetermined parameters or on an unsolicited, report-by-exception basis—which is both faster and more efficient. About This Manual This technical reference guide explains UtiliNet in great detail from application design through implementation and operation to after-sales services and support.

UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 system to be somewhat simplistic. Network users, when field testing to determine how far radios can communicate, describe it as either it does or it does not work. This is the nature of digital radio. Network designers and users benefit from a UtiliNet radio’s intelligence in many seen and unseen ways. The benefits of microprocessor-controlled communication algorithms are reduced installation time, reduced cost, and reliability uncertainties.
UtiliNet® PCMCIA IWR Card User Guide only way to insure RF connectivity, regardless of the product or the frequency, is to test the path. 2/2/2007 Calculating Latitude/Longitude Coordinates Each radio in the UtiliNet network is programmed with a unique latitudinal and longitudinal (lat/long) coordinate. These lat/long coordinates are used by the network to make logical routing decisions (see "Network Routing" on page 9-2 for more information).
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 has lat/long coordinates printed along the borders of the map. When considering the use of a USGS map for constructing and maintaining a UtiliNet network, here are some issues to evaluate: ٛ Because all USGS maps have a central reference, all derived lat/long coordinates will always be relatively correct to one another. As mentioned earlier, this is important when considering UtiliNet’s logical routing algorithms.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 relative to a dipole. If there is a doubt, this should be confirmed with the manufacturer. For our analysis, we need the dBi unit of measure, so a conversion factor is needed. The conversion factor is +2.15 dB, rounded to 2 dB for this example. Example: A “3 dB omni-directional” type antenna is used. The antenna gain may be stated as 5 dBi.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 calculated differently, using dipole antennas instead of isotropic antennas. Such is not the case here, but if it were, the 2 dB factors for dBd to dBi antenna gain conversions would not be included. Additional Path Loss Attenuation For non-line-of-sight paths, an additional factor must be included that corrects for variables such as terrain, obstacles (including buildings), foliage, people, or antenna height.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 Noise Floor Factor One of the factors that make the 800 to 900 MHz frequency band so attractive is the relatively low equivalent noise temperature of man-made noise. For a noisy business environment, this has been estimated to be 87 K at 915 MHz. Relative to an ambient antenna noise temperature of 298K, this translates to a noise floor increase of 1.2 dB. Thus, we will allocate 1 dB (rounded to the nearest dB) of the link budget to overcoming man-made noise.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 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® PCMCIA IWR Card User Guide 2/2/2007 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. For multi-tone interference, for example several strong paging transmitters in the area, it is recommended that the maximum interference level be limited to -30 dBm. In general, price increases exponentially with dynamic range.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 software, data is gathered from the remote radio and the master or repeater radio, assuming the two radios connect. Use the following procedure to collect data that should be recorded for each site: 1 Make a rough sketch of the site indicating the antenna location relative to some reference structure. 2 Note any additional antennas that may be at the site and include the antenna locations on the sketch.
UtiliNet® PCMCIA IWR Card User Guide 2/2/2007 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® PCMCIA IWR Card User Guide 2/2/2007 Domain Routing Domain routing is an optional routing configuration for radios with 412 or later firmware. It serves to eliminate undesirable routing choices by forcing packets to travel through a core highway of radios and not route through areas of poor connectivity. The network is divided into “core” and “domain” radios.

Quick A mood packet parameter that specifies to factor in both tickle and data success percentage when creating and ordering the scan lists. Reliable A mood packet parameter that specifies to limit “hop” distance to that specified by Short Hop Length [916BH] when creating scan lists.
