Exhibit 1: Narrative Statement in support of Experimental License Application by Qwest Communications 1. Background Qwest Communications is publicly held Local Exchange Carrier based in Denver Colorado. Our objective is to evaluate a PHS based wireless communication service to determine the viabililty of providing various Enterprise markets in the United States with this service. 2. Proposed experimentation program Qwest Communications has identified significant opportunities to serve it’s Enterprise customer base with wireless communications services as an extension of current PBX or Centrex service offerings. We propose to offer a limited mobility, voice and data service, to subscribers in their office locations. If the technology is determined to be a viable technology for this purpose, this type of small, localized system proposed here would be deployed in small numbers in different business facilities in the United States. The specific locations have yet to be identified. This experiment will test the market viability of a limited mobility, voice and data service for this market. While this type of service offer has proven to be very popular in other countries as an extension of basic wired services, the etiquette requirements of the Unlicensed PCS Band as well as the restrictive licensing of the Licensed PCS band have made this service unavailable to the US market. This experiment, using the existing Unlicensed PCS band between 1910MHz and 1920MHz, will demonstrate the economic viability of this type of offer in the US and can be used to justify additional development in available bands. 3. Technical information Qwest Communications proposes operation of Mobile telephone line extension equipment based on the Japanese RCR28 PHS Standard. This equipment is already approved to operate in the US in the Licensed PCS band just below 1910MHz, however the location of the testing facilities identified for this experiment are outside of Qwest’s Licensed PCS area. Qwest Communications proposes deployment of units with a maximum peak power of 200mW for mobile units. Due to the low power nature of these deployments; the fact that all equipment expected to be deployed is already approved for use in the adjacent licensed PCS band; Qwest believes operation of this equipment will have no adverse impact on other operators in nearby bands.

Equipment currently under consideration includes: type manufacturer model number handset UTStarcom WTL00535 MCU UTStarcom 20570004 CSC/WRT UTStarcom 41060074 All subscriber units have a transmission power limit of 10mW Average Power/80mW Peak Power while the infrastructure units transmit up to 200mW Average Power/1.6W Peak Power. Other RCR28 Standard PHS equipment will also be considered for use and in all cases this equipment will first be approved under Part 24 for operation below 1910Mhz. In the application, these units are shown as being “Experimental”. This is true for the 1910MHz ~ 1920MHz band being requested here. In all other ways, these units are not experimental and are, in fact, production units certified for use in the licensed PCS band.
