    Wireless Comes of AgeLong Range two-way Tower Gateway Base-stations (TGBs)TGB OptionsEmerging TechnologyCommunications Options QoS

    Cordova AMR/AMI Coming of Age

  • Coming of AgeHuman meter readers were relatively cheap; quick and easy to install; rugged and extremely reliable over long periods of useMultiple types of AMR techniques and technologies Wireless emerged- new problems including range limitations, spectrum interference and reliability issues Financial concerns about future operational and support costs Advanced AMR networks would provide the best solution to the cash flow delay typically 30-90 days 25% of water meters in the United States are now equipped with AMR

  • Long Range two-way Tower Gateway Base-stations (TGBs)AMR fixed base networks typically need hundreds (sometimes thousands) of cellular pole-top, or meter-based data concentrators, collectors or repeaters High infrastructure cost mostly from limited range of devicesTGB system delivers superior performance, lower infrastructure costs, minimizes maintenance overhead and reduce long-term deployment risksDesigned specifically to minimize infrastructure while maximizing range and signal reliability

  • TGB Range Criteria

    Use the tallest existing radio towers and efficient high-gain antennas capable of receiving very weak signalsAcquire clear nationwide primary use licensed radio spectrum with a low noise floorDesign high power endpoints (2 Watts) with state-of-the-art, all digital modulation techniquesDesign highly sensitive (-120 dBm to -130 dBm) all DSP based receiver base stations Develop meter-to-meter Buddy relay mode for hard to reach meters (those in basements, behind line-of-sight barriers, mountainous regions, etc.)

  • Existing Tower Infrastructure Over 4,000 existing tower sites covering over 90% of the population Integrate seamlessly with existing paging equipment, which allows the sharing of power, antennae and data back-haul channelsCritical service real-time TGB tower monitoring and maintenance Patented technology, long-range radio communications, low infrastructure cost, high reliability and existing tall towers provide a scalable fixed based network with high level of availabilityMature and proven technology

  • Option-Licensed/Private FrequencyLicensed for a section of the radio spectrumTower based radio infrastructure placed 5-15 miles apartTowers placed at a much lower density than data concentratorsEach tower will have a modem to provide the backhaul connectivitySpeed of data transmission will depend on the frequency usedSensus FlexNet solution is widely used in North America, particularly for one-way gas and water AMR servicesBritain uses this type of communication mainly by National Grid as part of their SCADA systemsSensus FlexNet solution provides 2 watts of broadcast power from the meters and 20 year battery life for gas and water AMR meters for daily updatesMunicipal utilities in the US are utilizing existing metropolitan WiFi infrastructures for multi-utility metering services in cities such as Lafayette, Burbank and Corpus ChristiAnything wrong with this idea?

  • Option-WiMaxAlso known as 4G, WiMAX is a last mile wireless solutuionBased upon a cellular antenna infrastructureWhere Wi-Fi is viewed as a local technology, WiMAX is a neighborhood/metropolitan technologyMeter Hardware requires WiMAX chipsetRequires the installation of antennas in a cellStructure with typical spacing of 3 to 10km, cost is fallingData speeds vary by distance of the endpoint from the antenna, and the number of endpoints using the connection from that antennaIEEE 802.16(x) defines the WiMAX standardPower consumption of WiMAX hardware is high

  • Emerging Wired/Wireless OptionsFemtocells are networks where low power wireless access points operating in licensed radio spectrums connect standard mobile devices to a mobile operators network using broadband connectionsCould be applicable in the future of Metering Systems

  • Emerging Wired/Wireless Options, contdActive Line Access (ALA) is a model whereby a gateway within premises is provided to support a range of servicesCustomer Premises Equipment is then installedALA discussions are still at a relatively early stageCould an emerging Service Provider with service strategies similar to Akamai have a place in AMR/AMI systems to prevent DDoS attacks, provide alternate routing, remote availability, security?

  • Emerging Wired/Wireless Technologies, contdPreviously discussed topicsPLC - generally used for utility applications, distribution and transmission operator SCADA systems, AMR, smart gridFixed Line PSTN, xDSL broadband, CableWireless Solutions cellular, low power radio (Zigbee, Mbus, Zwave), Presentation Focus on Long Range Radio

  • Communications QoSVarieties of individual types of physical media can be used together to deliver connectivityAny number of communications options could co-exist at any level of geographic granularityConsideration on the effects of lawnmowers and power tools on Power Line Carrier servicesConsideration of microwaves or Digital Enhanced Cordless Technology DECT telephones on wireless solutions real world experience; dirtbikeConsideration on the effects on Wi-Fi and ZigBee operating at 2.4GHz There are many discussions dismissing these issues as there are with those raising them

    Cordova AMR/AMI Coming of Age

  • ConclusionTGBs have lowered operational and maintenance costs while providing Operational improvementsSupply side savingsNew revenue opportunitiesCustomer Service ImprovementsEmerging solutions take advantage of existing infrastructures, Service Providers, municipal Wifis, etc. Not all ideas and solutions have a place in AMR/AMIConsideration of QoS must be investigated on emerging technology since normal home activities may affect some solutions (such as mowing the lawn, tuning up a dirt bike, etc.) Questions?
