1. MSS/ATC System Description
6. ICO plans to implement a MSS/ATC system that will provide multicast and
interactive services to customers. The ICO MSS/ATC system will provide full national coverage and services to users in buildings, as well as outdoors. ICO has designed the MSS/ATC system with the capability to provide multiple Internet-protocol-enabled services, including textmessaging, email, multicast broadband data and/or video, public safety, and telematics.
ICO constructed its G1 satellite to support radio protocols that are widely used or in the process of being widely implemented. The system is designed to operate with a range of vehicular and portable user terminals, including handheld terminals similar in size to current cellular phones and small accessory units to be connected to the user’s telephone, personal computer, or personal digital assistant.
7. Using a frequency-division duplex technology, the system will be deployed
using the forward mode of operation as defined in the Commission’s ATC rules,
using the 2010-2020 MHz band for terminal-to-satellite and terminal-to-base-station transmissions (“uplink transmissions”) and the 2180-2190 MHz band for satellite-to-terminal and base-stationto-terminal transmissions (“downlink transmissions”). Transmissions from satellite and terrestrial transmitters will be OFDM-based and time-synchronized to enable receivers to combine and process both signals. The system will dynamically allocate full duplex channels for satellite interactive communications based on spectrum reuse and traffic requirements.
While reserving capacity for MSS communications, terrestrial interactive services may utilize more capacity in the uplink and downlink bands where satellite services are unreliable or satellite"
"
9. MSS Coverage ICO certifies that its G1 satellite can provide MSS everywhere in
the United States, Puerto Rico, and the U.S. Virgin Islands one hundred percent of the time
insofar as technically possible, as required by Section 25.149(b)(1)(i) of the Commission’s
rules.
10. MSS Commercial Availability ICO certifies that its MSS services will be
commercially available in accordance with the coverage requirements for 2 GHz MSS systems,
as required by Section 25.149(b)(3) of the Commission’s rules. ICO stipulates, however, that
this certification is based upon an assumption that broadcast auxiliary service relocation issues
will be resolved in a manner that will permit ICO to offer nationwide commercial MSS at the
time when it plans to commence provision of MSS/ATC services. ICO states that if this
assumption proves to be incorrect, it may request a waiver of the commercial-availability gating
requirement at a later date. "
