Wind Power Project Planning — 
Avoiding Interference Through the Good Neighbor Approach

by Laura Fontaine and Roger Maier

Introduction
Wind energy is the world’s fastest growing alternative energy source.  In the United States, billions of dollars will be spent over the next several years on wind power projects.  However, as new wind turbine generators spin up, it’s important to note that they may pose an interference threat to microwave systems and broadcast stations licensed to operate in the United States.

Wind turbines can block the line-of-sight operation of microwave paths, potentially impacting path performance.  In addition, wind turbines have a potential to cause “ghosting” to television reception due to multipath interference.  Multipath interference occurs when signals reflect off of an object, in this case a wind turbine.

Many states have recognized the need for regulations addressing interference to radio signal transmissions.  Specifically, local planning authorities typically require project developers to ensure that interference will not be caused by the wind turbines and in some cases to notify the telecommunications operators of the proposed windmill operation.  Other factors prompting proactive investigations into potential interference include the need to prevent legal and regulatory interference allegations and the desire to promote goodwill within the community: a good neighbor approach.

Case Study

Scope of Work
A project developer needed to evaluate the potential impact to microwave path operations and TV reception in the vicinity of a proposed windmill generating facility.  The operator provided Comsearch with the coordinates, heights and blade radius of ten wind turbines.

Microwave Path Obstruction Analysis

GeoPlanner
Comsearch used our GeoPlannerTM mapping tool and proprietary microwave path databases to analyze the potential effects to microwave stations in the area.  We incorporated ten wind turbine locations into GeoPlanner and defined the area of interest.  The geometry of each turbine can be modeled depending on its proposed configuration of hub height and rotor diameter, giving the entire structure its appropriate configuration.  The turbine locations are then plotted onto the area maps using their lat/long coordinates, which can often be established using a decent GPS system.  The microwave paths, which are sometimes plentiful in the attractive higher ground areas suited for several wind plant sites, are then numerically mapped onto the site layout to determine potential areas of interference where signal paths might intersect with wind turbine tower locations. In the example, wind turbines with hub heights of 60 meters and rotor diameters of 80 meters were modeled.

Figure 1 is a map of the area showing the wind turbines tower locations (labeled by a cross within a gray circle) and the microwave paths (shown as blue lines).  We included supporting topographic maps to provide a comprehensive view of the project area.

Figure1. Proposed Wind turbine Locations and Microwave Paths

Obstruction Analysis
Comsearch performed a microwave path obstruction analysis to determine instances where the wind turbine blades would impinge on the maximum diameter Fresnel Zone of the microwave paths.  Most of the energy in a microwave path is contained within an area around the path known as the Fresnel Zone.  The Fresnel Zone looks like an ellipse with the microwave antennas as the focus points.  The maximum diameter, or worst-case Fresnel Zone is the mid path Fresnel Zone value applied to all points along the path.  Blockage of any portion of the Fresnel Zone can degrade the performance of the microwave path.

Worst-case Fresnel Zones are depicted in Figure 2 as the area bounded by the yellow lines on either side of each microwave path.

Figure 2. Microwave Paths Fresnel Zones and Affected Wind turbines

Results
Comsearch found that four turbines (shown in red in Figure 2) were potentially obstructing seven of the twenty-two microwave paths in the area.  Consequently, Comsearch recommended a more detailed Fresnel Zone analysis.  Based on the results of the detailed analysis, two of the four turbines were identified as an obstruction to five microwave paths. 

Conclusion
The project developer used this information to relocate the two turbines to avoid any impact to the paths.

TV Station Reception Analysis

Comsearch considered twenty-two licensed TV stations within a 200-mile radius of the area and performed field measurements to evaluate potential interference to TV reception.

Measurements
We performed measurements at five sites in the vicinity of the area.  The purpose of the testing was to obtain a baseline condition of the off-air TV reception in the area before the installation of the wind turbines.

We also performed a second set of measurements in another town where fifty wind turbines have been installed and are operational.  The wind turbines in this area have had a known adverse effect on TV reception in the vicinity.  Measurements for video level and quality were taken at eight locations around the wind turbines.  The purpose of these measurements was to:

• Determine blockage and multipath interference created by a single wind turbine and by multiple wind turbines,

• Determine electromagnetic noise generated by the wind turbines in the TV reception band,

• Collect data to construct a RF propagation model of the turbine effect on TV reception at the proposed site and for other future installations.

Results at Operational Site
The largest concentrations of TV reception problems reported were to the south and southwest of the site.  Of the eight locations, we found reflected signals from the wind turbines at three locations.  At these locations, the signal level of some channels would vary, resulting in ghosting on a TV set.  In these cases, the wind turbines were in the direct path of the TV signals.  The rate of signal variance appeared to correlate to the rotation of the turbine blades.

Conclusion
Based on the TV signal measurements performed at the operational wind turbine generator site, we collected data to develop a prediction model for quantifying the impact of wind turbines on off-air TV reception.  The measured data indicates that blockage from the wind turbines can cause up to 8 dB of TV signal reduction as well as multipath conditions that cause ghosting, depending on the relative location of the TV receive antenna and the wind turbines.  Also, the electromagnetic noise produced from wind turbine generators is more prominent at the Low VHF channel and is a function of separation distance between the TV receiving antenna and the wind turbines.  For example, it is expected that Channels 2 - 6 will be more affected by the noise generated than Channels 7 and above.  These factors alone, or in combination, degrade TV reception in areas in the vicinity of wind turbine generators.  Comsearch will conduct additional measurements, research, and analysis to define all of the relevant parameters that will make the off-air TV reception model a useful prediction tool for future installations.

New Trends in Spectrum Access and Flexibility

Effective Management and Coordination — Key Factors 
to Fast and Affordable Spectrum Access

by Jim Titzell and Chris Hardy

The State of Spectrum Management Today
Over the last ten years, radio spectrum management in the US has been progressively moving toward more flexible approaches to allocation, utilization and administration of this precious asset.  In the early 90’s the FCC began utilizing spectrum auctions, allowing economic and market forces to define the public interest and determine new spectrum ownership.  Part of this evolution has been the emergence of a trend toward a more flexible regime in the use of purchased spectrum and a less intrusive government oversight of license transfer and amalgamation of spectrum assets.  Correspondingly, Cellular, Personal Communications Services (PCS), Local Multipoint Distribution Services (LMDS), Multichannel Multipoint Distribution Services (MMDS), and Point to Point and Point to Mulitpoint operations are experiencing a stringent economic shakeout, and their related spectrum assets are in various states of availability and demand. Bankruptcies and acquisitions are driving the calculus of spectrum availability.  Add to this the utilization of unlicensed spectrum blocks, optical networks and new licensed spectrum on the horizon and you have a vast array of choices to fulfill your communications requirements.

The Choices
The creation of access managers and the appearance of secondary markets for the lease of licensed spectrum have increased the number of ways to scale and provision communications solutions to meet business requirements.  There are multiple solutions to most requirements - solid business case analyses and qualitative assessments need to be employed to winnow the mix to solid and effective options.  Examples in the current marketplace are:

• The Commission adopted a new class of commercial FCC license called the Guard Band Manager license for the 700 MHz band.  Guard Band Managers are engaged in the business of subdividing the spectrum they acquired at auction and leasing it for value to third parties, including both commercial service providers and private wireless users. Guard Band Managers are required to adhere to strict frequency coordination and interference rules, and control use of the spectrum so as to facilitate protection for public safety. The Guard Band Manager may subdivide its spectrum in any manner it chooses and make it available to system operators or directly to end users for fixed or mobile communications - consistent with the frequency coordination and interference rules specified for these bands.
  
  

• In the Secondary Markets proceeding, the Commission has begun to explore possible market arrangements that would give licensees greater flexibility to authorize others to use otherwise unused portions of their unlicensed spectrum.
   

• In the case of Ultra-Wideband (UWB), the Commission has implemented an easement approach that allows the systems to operate in encumbered bands.
  
  

• In Docket 00-19, Amendment of Part 101, the Commission modified their rules to permit private operational fixed systems to lease reserve capacity to common carriers for their common carrier traffic. 

38 GHz Spectrum Capacity Agreements
As the Commission continues to move away from existing command and control mechanisms and toward more market oriented approaches to spectrum allocation and flexible use regimes, access to spectrum will be much more dynamic than currently exists today.  It is conceivable that with increasing deregulation, combined with advancing technology that dynamically utilizes the spectrum, there will be a need for some type of brokering and bandwidth trading services.

Comsearch has responded to this shift in spectrum policy by developing new software and services to manage and represent an individual licensee’s excess spectrum capacity.  This representation is designed to facilitate a potential user’s access to spectrum resources by efficiently matching demand with availability.  Through this micro spectrum management process, interference issues are considered and resolved, and system implementation can be accomplished quickly.

Regulatory Rap

MICROWAVE

Have you checked your interference temperature lately?
The Commission wants you to.  The much-anticipated report from the newly created Spectrum Policy Task Force was presented to the Commission on November 7, 2002.  The report focuses on three main areas of spectrum policy: Access, Technology, and Rights and Responsibilities.  The key recommendations include some controversial and novel approaches to spectrum management, including the creation of a quantitative standard for acceptable interference - the “interference temperature” - to quantify and manage interference. The new metric would be used to establish maximum permissible levels of interference on a band-by-band basis, thus placing a limit on the noise environment in which receivers would be required to operate.  Quantifying and monitoring this type of environment will present some interesting challenges.  In addition to the new “temperature” metric, the report recommends that the Commission move toward more flexible and market-oriented (can anyone say auction) spectrum policy; consider the use of the time dimension, in addition to the current use of frequency, power and space, when allocating and assigning spectrum rights; and shift from the current dominant “command and control” model to either an exclusive use or commons approach.The Task Force report will most likely form the basis for a future Notice of Inquiry or Notice of Proposed Rule Making. (Dkt No 02-135).  DOC-228242A1.pdf   DOC-228542A1.pdf 

Need spectrum, just defrost it.
Ten years ago the Commission put the 2.1 GHz band in the proverbial “spectrum freezer.”  In a Second Report and Order (Order), adopted on November 7, the Commission defrosted the band as part of a new allocation for advanced wireless services.  The Order allocated a total of 90 MHz to the fixed and mobile services, including 1710 – 1755 MHz that is currently used by Federal Government systems and 2110 – 2155 MHz that is primarily encumbered by commercial point-to-point microwave users.  The 2150 – 2155 MHz band segment is currently licensed to Multipoint Distribution Service (MDS) users.

Relocation of incumbent systems remains one of the more complex and critical issues in the proceeding.  In the case of the 2110 – 2150 MHz spectrum where there are approximately 8,000 systems, the Commission has proposed to use existing relocation rules previously employed in the PCS 1.9 GHz band clearing.  For MDS licensees, the Commission opted to consider relocation spectrum and procedures in a future proceeding.  Industry groups have asked the Commission to consider using auction proceeds to help fund the relocation effort.  The Commission seeks comment on various licensing, technical and operational rules.  (Dkt No 00-258, 02-253) DOC-228237A1.pdf  DOC-228237A2.pdf  DOC-228237A3.pdf  DOC-228237A4.pdf

Off the hook at last!
After numerous requests from bidders and the industry, the Commission finally decided to grant bid relief to the winners of the beleaguered PCS C&F Block Auction # 35. In the Order issued on November 14, 2002, the Commission said it would waive the default rules for bidders electing the relief.  The Order also imposes no restrictions on electing bidders’ ability to acquire such spectrum in future auctions.  The spectrum awarded in the auction remains in limbo with the Supreme Court expected to hear the case sometime next year. http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-228506A1.pdf

Two auctions are better than one?  
As if one auction wasn’t bad enough, the FCC’s Office of Plans and Policy released a working paper #38 proposing the use of two-sided auctions to facilitate restructuring of encumbered spectrum.  Under the proposal, incumbents would have two choices.  They could choose not to participate and continue with current use without additional flexibility, or participate and be granted immediate flexibility, and keep the auction proceeds from the sale of their spectrum. http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-228557A1.pdf

Part 101 Update
Despite being released on July 31, the Part 101 Docket 00-19 has incurred delays getting to print in the Federal Register.  Our contacts with the FCC indicate that it is now expected to hit the Federal Register sometime early next year.  Since the Rules do not go into effect until 60 days after publication in the Federal Register, we are probably looking at March as the earliest implementation date.

ITS Coming!
Your car may soon be carrying on more mobile wireless communications than you or your teenage kids combined.  On November 7, the Commission issued an NPRM seeking comment on proposed licensing and service rules for the 5.9 GHz band for Dedicated Short Range Communications in the Intelligent Transportation Systems Radios Service (ITS).  This band segment 5.850 – 5.925 is adjacent to the lower 6 GHz point-to-point spectrum.  These systems are being designed to provide wireless links to transfer information between vehicles traveling at high speeds and roadside units.  The NPRM tentatively concludes that the 5.9 GHz band should be used primarily for public safety purposes and seeks comments on a number of issues. ET Docket 98-95.  http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-02-302A1.pdf

New Rules for Broadcast Auxiliary Services
On November 13, 2002, the Commission released a Report and Order in ET Docket 01-75 updating the Broadcast Auxiliary Service (BAS) rules. The Order conforms certain technical rules, such as transmitter power and emission limits, for the BAS, Cable Television Relay Service (CARS) and Fixed Microwave Services (FS), and allows certain additional users of wireless assist video devices on unused TV channels.  The Commission further adopted rule changes designed to increase spectrum efficiency by ensuring that similar services operating on shared spectrum are regulated in a consistent manner. The BAS, CARS, and FS share several frequency bands, but in some cases have operated under different technical rules.  http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-228432A1.doc

Ultra-Wideband Update
In an ongoing review of standards surrounding UWB use, the FCC released a staff report on “Measured Emissions Data For Use in Evaluating The Ultra-Wideband Emissions Limits In Frequency Bands Used By the Global Positioning System.”  Comments are due November 22, 2002. http://hraunfoss.fcc.gov/edocs_public/attachmatch/DA-02-2786A1.pdf

Does the Public Safety Pool Need More Lifeguards?
The FCC is soliciting comments on whether to modify the existing frequency coordination procedures for the Land Mobile Public Safety Pool below 470 MHz by expanding competitive frequency coordination. (Dkt No. 02-285, FCC No. 02-255). FCC-02-255A1.pdf 

Year 2000 Biennial Regulatory Review - Amendment Of Part 22 of the Commission's Rules
Amended Part 22 of the FCC's rules by modifying or eliminating various rules that have become outdated due to technological change, increased competition in the Commercial Mobile Radio Services, or supervening rules. (Dkt No. 01-108, FCC No. 02-229)    FCC-02-229A1.pdf  FCC-02-229A2.pdf

Streamlining Part 25 Rules for the Licensing of Earth Stations and Space Station Satellite Networks
Proposed revising Part 25 of the Commission's rules to increase the number of earth station applications that can be processed routinely, or, in the alternative, to streamline the processing of earth station applications. (Dkt No. 00-248, FCC No. 02-257). FCC-02-257A1.pdf 

On September 26, 2002, the FCC released a Further Notice of Proposed Rulemaking covering a number of issues involved with the routine licensing of satellite earth stations.  The FNPRM covers issues involving antenna patterns, CSATs, access techniques for VSAT systems, uplink and downlink EIRP densities.  If adopted, the criteria for routine authorizations will be expanded to consider higher-powered system employing smaller diameter antennas.  The FNPRM has not at this date been placed on public notice.  Comments are due 75 days after publication in Federal Register, reply comments in 105 days after FR.

FCC Declines to Approve ECHOSTAR-DIRECTV Merger
On October 10, 2002, the FCC announced that it was declining to approve the transfer of licenses from Echostar Communications Corporation and Hughes Electronics Corporation to a new entity.  The FCC stated that the two companies did not demonstrate that doing so would serve the public interest.  The FCC ruled that the merger would constitute a loss in competition and would harm consumers by: (1) eliminating an existing viable competitor in every market; (2) creating the potential for higher prices and lower service quality; and (3) negatively impacting future innovation.

The FCC provided Echostar and DirecTV 30 days to file an amended application to ameliorate the FCC’s anti-competitive concerns and to file a petition to delay the hearing.  Details on the Echostar-DirecTV merger can be found at: http://www.fcc.gov/transaction/echostar-directv.html.  (Dkt No 01-348).  DOC-227263A1.pdf  DOC-227263A2.pdf  DOC-227263A3.pdf  DOC-227263A4.pdf  DOC-227263A5.pdf 

FCC application processing fees
In July, the FCC announced that there would be an increase in application processing fees.  Since this notice did not reach the Federal Register until November 7, 2002, the effective date for the new fee structure is December 5, 2002.  Details on the new fees and related orders can be found at: http://www.fcc.gov/fees/appfees.html.

Intelsat to Acquire Comsat Assets and FCC Opens Intelsat Space Access Direct to Users
On October 25, 2002, the FCC granted the applications of Lockheed Martin, Comsat Corp, and Comsat Digital Teleport to assign 29 licenses to Intelsat, Ltd., the privatized company formerly known at the INTELSAT.  The transfer consists of:  (1) seventeen common carrier licenses from Comsat Corporation/CWS (File No. SES-ASG-20020405-00564); (2) the assignment of eight non-common carrier licenses from Comsat Corporation/CWS (File No. SES-ASG-20020405-00565); (3) the assignment of four non-common carrier licenses from CDTI (File No.SES-ASG-20020405-00566); (4) the assignment of four common carrier licenses from Comsat General (File No. SES-ASG-20020405-00561); (5) the assignment of one non-common carrier license from Comsat General (File No. SES-ASG-2002-0405-00552).

Upon the closing of the proposed transaction, Intelsat Ltd. would hold the Title III licenses and Intelsat USA License Corp. would hold the section 214 authorizations.  Intelsat Global Service Corporation would hold title to the earth station facilities and equipment as well as to real estate in Clarksburg, Maryland and Paumalu, Hawaii.

In conjunction with this action, on November 19, 2002, the FCC adopted IB Docket No. 00-91, regarding the ability of users to access directly the INTELSAT satellite systems. In compliance with the ORBIT Act and relative to the privatization of Intelsat and the transfer of licenses from former INTELSAT signatory Comsat to Intelsat the FCC has terminated previous rulings requiring user to access the INTELSAT space stations through the U.S. signatory Comsat. Details on the on-going Intelsat-Comsat acquisition can be found at: http://www.fcc.gov/transaction/intelsat-comsat.html.

Engineering E911 Network Solutions
by Erik Rasmussen

Have you ever wondered what is involved when 911 is dialed from a telephone?  Today, if you call from a wireline phone, your call, as well as your calling location in the form of a street address and phone number, is transferred to the nearest Public Safety Answering Point (PSAP).  The PSAP will promptly route your call to the appropriate emergency medical, fire, and law enforcement agencies.  If calling from a wireless phone, the process is not so simple.

Wireless phone users are mobile, and providing accurate location information to PSAPs has been impossible until very recently. However, this has all begun to change with the development of technology to enable wireless phones to be located with far greater precision. With the advent of wireless location technology has been the FCC’s Enhanced 911 (E911) rules which requires improved effectiveness and reliability of wireless 911 services.  The FCC divided this mandate into two phases to be implemented over an eight-year period and completed by December 31, 2005.  Phase I required wireless carriers to provide PSAPs with the wireless 911 caller’s telephone number, as well as the location of the cell site serving the emergency call.  Phase II requires wireless carriers provide PSAPs with specific geographic coordinates for the wireless 911 caller, in addition to the Phase I information.  The FCC has dictated certain deployment schedules for the wireless carriers who have not complied, and have been fined.

In order to meet the FCC imposed deadlines for E911 deployment, wireless carriers have adopted a variety of different geolocation solutions.  The two major subdivisions are network-based solutions and handset-based solutions.  E911 rules state different accuracy requirements for each solution.  Network-based solutions are required to have 100 meter accuracy for 67% of wireless 911 calls and 300 meter accuracy for 95% of calls.  Handset-based solutions are required to have 50 meter accuracy for 67% of calls and 150 meter accuracy for 95% of calls.

Comsearch’s sister company, Grayson Wireless, is one of the leading suppliers of Phase II-compliant geolocation solutions.  Grayson’s Geometrix^® product is the market leader for network-based solutions.  Grayson’s Geometrix uses two different techniques to locate wireless 911 callers: Time Difference of Arrival (TDOA) and Angle of Arrival (AOA).  With both techniques, Grayson Wireless Location Sensors (WLS’s) are installed at the wireless carrier’s basestations.  With TDOA, which is used in 100% of Geometrix installations, the WLS’s measure the time difference of a wireless 911 caller’s signal arrival at various basestations.  Using the measured time difference at a minimum of three basestations, the coordinates of the caller can be determined.  AOA, which is employed as a supplement to TDOA when three-site visibility is not available, utilizes a phased antenna array to determine the angle at which a wireless 911 caller’s signal impinges the face of the antenna array.  This technique requires only two site hearability, but requires special antennas at the basestations, which most likely requires special zoning and structural analysis.  Grayson Wireless has optimized its TDOA-only solution so that it produces Phase II-compliant accuracy in the vast majority of applications, thus minimizing the need for AOA.

Geometrix Architecture

As a result of Grayson’s Geometrix acceptance in the industry, the client list grows on a monthly basis.  Comsearch has provided Grayson Wireless with engineering expertise from our Wireless Engineering group to help expedite the design and deployment of the Geometrix systems. 

As members of the Network Engineering team, Comsearch engineers have been responsible for designing Geometrix systems for various markets across the United States for clients such as AT&T Wireless, Centennial Wireless, and Telecorp.  The design process entails analyzing call data and running accuracy predictions using a custom software package to determine the optimal location and configuration for WLS’s.

Comsearch is proud to have this opportunity to play a role in the quick emergency response to 911 callers across the nation.
