PRESS RELEASE

RESTON, VA, - Today Comsearch, the nation's leading radio frequency (RF) engineering company, announced at the United Telecom Council's (UTC) Expo 2000 in Phoenix, that it is launching a comprehensive new eight-step Radiation Safety Services Program designed to help wireless telecommunications operators and site owners fully comply with the Federal Communications Commission's (FCC) and Occupational Safety and Health Administration's (OSHA) stringent guidelines and standards for radiation hazard (RadHaz) safety that are mandated for compliance by September 1.

According to the FCC, operators and owners must implement and document site-wide compliance efforts to show they have a validated radiation safety program in place. Comsearch has assisted facility managers in determining the necessary steps and services for such site evaluation: In-house computer modeling of the RF environments, on-site RF measurements, staff training, development of safety plans, regulatory support, and licensing and lease agreement support.

With the September 1 deadline looming, Comsearch is launching its new Radiation Safety Services Program that helps wireless operators meet the stringent government requirements by providing the following comprehensive package of services:

1. Facility RF Radiation Level Analysis - RF power density calculations to define radiation hazard areas, controlled/uncontrolled boundaries and locations for appropriate signage.



2. Facility RF Radiation Measurements (Broad and Narrow Band) - On-site measurements using broad band (isotropic probes) and narrow band (spectrum analyzers or test receivers) instrumentation to determine the radiated levels throughout the facility.



3. General Radiation Safety Training - General theory, practical applications and all safety regulations (2 days).



4. Site Specific Radiation Safety Training - Three-day course that covers all of the general Radiation Safety training plus an extra day for the site-specific conditions of a customer's facility. This can be taught at a location designated by the customer.



5. Facility RF Radiation Safety Plan (Required by OSHA) - Preparation of safety procedures and practices documentation. All facility personnel must be made aware of safety procedures.



6. Radiation Safety Exhibit for FCC License Application (When required by the FCC) - Preparation of supporting documentation for FCC license applications.



7. Facility Segregation Plan of Controlled and Uncontrolled Areas and Proper Radiation Sign Locations - Review of site RF conditions to define boundaries for controlled and uncontrolled areas and recommend locations for appropriate warning signs. This is especially important for new facilities or existing facilities that have added transmitting equipment.



8. Assist Facility Owners in Lease Agreements and RF Management of a Facility from a Radiation Safety Standpoint - Development of proper lease terminology and operational restrictions for tenants at a shared facility.

"The proliferation of RF transmitting facilities worldwide is staggering," stated Lester Polisky, director of Comsearch's Radiation Safety Services Program. "When Comsearch entered the wireless industry more than two decades ago, there were only a few satellite and point-to-point microwave facilities worldwide, serving primarily government and corporate communications needs. Today, virtually everyone who owns a pager, cell phone, or Palm Pilot^® is transmitting radio frequencies at some level. Antenna facilities can be found on hillsides, on roof tops, and even hidden in the steeples of churches-all emitting ever increasing levels of RF electromagnetic energy. With every exciting new technology comes safety concerns and proposed regulations. The FCC felt it was time to impose and strictly enforce compliance with national guidelines for RF radiation safety," Polisky said.

With over 23 years of wireless telecommunications engineering experience and expertise, Comsearch has assisted thousands of facility managers all over the United States and has performed these types of RadHaz analytical and measurement services for some of the most complex commercial and government facilities.

Comsearch (www.comsearch.com) designs, deploys, and optimizes wireless networks worldwide. Comsearch provides service solutions, engineering and GIS data to operators of Microwave, Mobile Satellite, Cellular, PCS,
and Fixed Wireless networks. In addition to experienced engineers, the company's software line addresses the
engineering challenges of fixed network design and spectrum relocation. Comsearch, located in Reston, Virginia, is an Allen Telecom company (NYSE:ALN).
