For over a quarter century, Comsearch has provided expert engineering services, software, data and information products to the wireless industry. We have been gathering data on microwave, satellite, PCS, broadband and cellular networks from an abundance of sources beginning in the 1970's. Since then, we have continually verified, updated and managed this extensive database amassing one of the largest private collections of engineering data in the telecommunications industry. If you're using our data, you're getting the most accurate information available.

Comsearch created DataZone^SM--an online source to provide critical statistics and up-to-date information - to help providers identify prospects for their products and services, perform competitive research and identify interference issues. GIS data offerings in DataZone^SM are in dem and shapefile formats for easy importation into any of the ESRI suite of software products.

GeoPlanner^TM products offer graphical representations of telecom systems based on Comsearch's extensive, value-added databases. The GeoPlanner product line¾ accessed through free GIS mapping tools¾offers technical and regulatory data for any geographical area in the United States. Industry professionals use GeoPlanner to perform sophisticated telecom and competitive market analyses. Currently there are four GeoPlanner modules available. Although each can be purchased separately, all four can be combined to provide the most comprehensive view of the telecom industry for any given area. The four GeoPlanner modules are:

• Microwave GeoPlanner--comprehensive package of microwave path data that includes critical technical parameters of licensed facilities within a geographic area or band. The product is available in three editions. Each microwave path is represented by a line and includes features such as licensee contact information, coordinates, equipment types and frequency.

• MAS GeoPlanner--easily identifies available MAS spectrum in any geographic service area. Available in both digital and printed versions, MAS GeoPlanner removes the trial and error methodology of locating areas of available spectrum by accurately defining actual frequency counts in a given area.

• Network GeoPlanner--based on the Microwave GeoPlanner Gold Edition, offers vital competitive and technical data for any given carrier, and radio or antenna manufacturer. Network GeoPlanner allows you to quickly view networks and easily analyze market conditions-data can be queried and manipulated to meet individual business objectives.

• Wireless GeoPlanner--addresses broadcast (AM, FM, TV, DTV, HDTV), private land mobile, and earth station networks. Wireless GeoPlanner can easily integrate with our other GeoPlanner products, providing a complete, comprehensive overview of spectrum utilization in any telecom market.

Comsearch's GIS Data--a worldwide variety of terrain, morphology/clutter, 3-D building, satellite imagery and aerial photography, arranged by geographic, political boundaries, or FCC License Areas, available in ESRI formats. Data in this section can be used in conjunction with other reports for a complete picture on how and where to build a wireless network. Comsearch's data can help you conduct reliable "what if" scenarios for facility placement and identify optimal design locations for maximum network performance.

Telecom Data Reports--snapshots in time of the wireless industry organized by frequency band, type of service or product, including Telecommunications Carrier Reports, Spectrum Usage Studies, AuctionPlanner Updates, and PCS Incumbent Status Reports. These reports are delivered in flexible formats for easy manipulation and analysis.
