TIA Urges FCC to Consider Impact of Some Proposed Rules for Wireless Communications Services Interference

Proposed Rules May Constrain Operation of WCS

Arlington, Va. – The Telecommunications Industry Association (TIA) today filed comments with the Federal Communications Commission, urging it to consider the impact of proposed rules for Wireless Communications Services (WCS) interference.

"The significant technological progress in wireless broadband services, devices, and applications are deeply impacted by spectrum availability," said TIA Vice President for Government Affairs Danielle Coffey. "TIA lauds the National Broadband Plan's recognition of this, and sees the rapid establishment of sound and effective interference rules for WCS operations as crucial to making 20 MHz of spectrum available for wireless broadband. However, it is important to avoid unnecessary delays in establishing WCS interference rules based on sound science."

In the filing, TIA acknowledged that, to allow deployment of WCS services, it is vital that effective interference rules are adopted that protect Satellite Digital Audio Radio Service (SDARS) and federal and non-federal Aeronautical Mobile Telemetry (AMT) operations.

"The Commission's proposed interference rules should accomplish this goal. However, TIA urges the Commission to ensure that WCS services and devices can operate in a practical and useful manner with the proposed duty cycle limits,. TIA is concerned that the proposed duty cycle limits may constrain operation of WCS," said Coffey. TIA also recommended that the differences between proposed time division duplex (TDD) and frequency division duplex (FDD) duty cycles be clarified. "The Commission has not explained the discrepancy between its proposed TDD and FDD duty cycles. Both of these provisions could limit the user experience of WCS services."

TIA urged the Commission to consider the interests of all parties as established in the record and finalize WCS interference rules.
