CTIA, NENA, APCO, and NPSTC Ask FCC to Act on Wireless Microphones and 700 MHz
On 2/23 CTIA - The Wireless Association®, the National Emergency Number Association ("NENA"), The Association of Public-Safety Communications Officials - International ("APCO"), and the National Public Safety Telecommunications Council ("NPSTC") filed a joint letter with FCC in WT Docket No. 08-167 asking it to act on the issues of wireless microphones' continued use of 700 MHz.
(Oddly the letter is not on the CTIA website even today, but was reported by FierceWireless.)
The letter stated,
"Harmful interference from unauthorized low-power devices operating in the 700 MHz band threatens to prevent licensees from realizing the benefits to public safety that the 700 MHz band promises. We understand that there is an item currently before the Commission to address low-power devices in the 700 MHz band and urge you to take action to curb the harmful use of these low-power devices.The joint parties then said they
It is of critical importance that low-power auxiliary devices do not cause harmful interference to critical communications - and the commercial communications that enable ordinary Americans to reach public safety in their moments of need. As both public safety and commercial licensees begin to utilize spectrum from broadcasters who have completed their digital transition, we ask that the Commission take action to clear the 700 MHz band of unauthorized low-power auxiliary users. By clarifying in an Order that low-power auxiliary devices must not interfere with authorized public safety and commercial licensees, and that those devices must accept all interference from licensed users, the Commission sends a strong signal to all users of these devices that the public safety benefits of the 700 MHz spectrum outweigh any - licensed or unauthorized - use of the band."
"urge the Commission to require that operation of all low-power auxiliary devices in the 700 MHz band cease no later than one year from the adoption of an Order and issue a Consumer Advisory informing the public. Additionally, in order to speed the deployment of public safety and commercial systems in the 700 MHz band, the Commission should require low-power users to cease operation within 60 days of notice that a licensee intends to initiate or change its wireless operations such that the low-power devices will likely cause interference."As we pointed out previously, this 60 day issue - originally proposed by NAB, MSTV and Shure - has the practical problem that almost all wireless microphones in use are illegal and hence not in any public database. (Perhaps Shure has such a database internally and might be willing to share it in exchange for immunity from criminal prosecution of their clients?)
So far Shure and fellow travelers have not addressed the points raised in this joint filing.
