   (d) Unless otherwise specified, the channels listed in Tables 4A and 4B
   are available only to eligibles in the SMR category--which consists of
   Specialized Mobile Radio (SMR) stations and eligible end users. 800 MHz
   high density cellular systems, as defined in § 90.7, are prohibited on
   these channels. These frequencies are available in non-border areas.
   The spectrum blocks listed in Table 4A are available for EA-based
   services (as defined by § 90.681) prior to January 21, 2005. No new
   EA-based services will be authorized after January 21, 2005. EA-based
   licensees who operate non-high-density cellular systems prior to
   January 21, 2005, may choose to remain on these channels in the
   non-high-density cellular portion of the 800 MHz band (as defined in
   § 90.614). These licensees may continue to operate non-high-density
   cellular systems and will be grandfathered indefinitely. The channels
   listed in Table 4B will be available for site-based licensing after
   January 21, 2005, in any Economic Area where no EA-based licensee is
   authorized for these channels.

   three years after the release of a public notice announcing the
   completion of band reconfiguration in that region;

   (2) Only to eligible applicants in the Public Safety or Critical
   Infrastructure Industry Categories from three to five years after the
   release of a public notice announcing the completion of band
   reconfiguration in that region;

   (3) Five years after the release of a public notice announcing the
   completion of band reconfiguration in that region, these channels
   revert back to their original pool categories.

   (h) In a given 800 MHz NPSPAC region--except for the counties listed in
   § 90.614(c)--channels below 471 listed in Tables 2 and 4B which are

   (i) Special Mobilized Radio Systems licensees who operate systems,
   other than 800 MHz high density cellular systems, on any of the public
   safety channels listed in Table 1 prior to January 21, 2005, are
   grandfathered and may continue to operate on these channels
   indefinitely. These grandfathered licensees will be prohibited from
   operating 800 MHz high density cellular systems as defined in § 90.7.
   Site-based licensees who are grandfathered on any of the public safety
   channels listed in Table 1 may modify their license only if they obtain
   concurrence from a certified public safety coordinator in accordance
   with § 90.175(c). Grandfathered EA-based licensees, however, are exempt
   from any of the frequency coordination requirements of § 90.175 as long
   as their operations remain within the Economic Area defined by their
   license in accordance with the requirements of § 90.683(a).

   (j) Licensees operating 800 MHz high density cellular systems on the
   channels listed in § 90.614(a), prior to January 21, 2005, may elect to
   continue operating on these channels and will be permitted to continue
   operating 800 MHz high density cellular systems (as defined in § 90.7)
   in this portion of the band. These licensees will be grandfathered
   indefinitely subject to the provisions of § § 90.673, 90.674 and 90.675.

   (k) Licensees may operate systems other than 800 MHz high density
   cellular systems (as defined in § 90.7) on Channels 511-550 at any
   location vacated by an EA-based SMR licensee. For operations on these
   channels, unacceptable interference (as defined in § 22.970 of this
   chapter and § 90.672) will be deemed to occur only at sites where the
   following median desired signals are received (rather than those
   specified in § 22.970(a)(1)(i) of this chapter and § 90.672(a)(1(i). The
   minimum required median desired signal, as measured at the R.F. input
   of the receiver, will be as follows:

   (1) Mobile units (except in Puerto Rico and the U.S. Virgin Islands):

   (i) For channels 511 to 524--the minimum median desired signal levels
   specified in § 22.970(a)(1)(i) of this chapter and § 90.672(a)(1)(i)
   shall apply;

   (ii) For channels 524 to 534--the minimum median desired signal level
   shall increase linearly from the values specified in § 22.970(a)(1)(i)
   of this chapter and § 90.672(a)(1)(i) to -70 dBm;

   (iii) For channels 534 to 550--the minimum median desired signal level
   shall increase linearly from -70 dBm to -65 dBm.

   (2) Portable units (except in Puerto Rico and the U.S. Virgin Islands):

   (i) For channels 511 to 524--the minimum median desired signal levels
   specified in § 22.970(a)(1)(i) of this chapter and § 90.672(a)(1)(i)
   shall apply;

   (ii) For channels 524 to 530--the minimum median desired signal level
   shall increase linearly from the values specified in § 22.970(a)(1)(i)
   of this chapter and § 90.672(a)(1)(i) to -80 dBm;

   (iii) For channels 530 to 534--the minimum median desired signal level
   shall increase linearly from -80 dBm to -70 dBm;

   (iv) For channels 534 to 550--the minimum median desired signal level
   shall increase linearly from -70 dBm to -65 dBm.

   (3) Mobile units operating in Puerto Rico and the U.S. Virgin Islands:

   (i) For channels 511 to 530--the minimum median desired signal levels
   specified in § 22.970(a)(1)(i) of this chapter and § 90.672(a)(1)(i)
   shall apply;

   (ii) For channels 531 to 534--the minimum median desired signal level
   shall increase linearly from -80.2 dBm to -70 dBm;

   (iii) For channels 534 to 550--the minimum median desired signal level
   shall increase linearly from -70 dBm to -65 dBm.

   (4) Portable units operating in Puerto Rico and the U.S. Virgin
   Islands:

   (i) For channels 511 to 530--the minimum median desired signal levels
   specified in § 22.970(a)(1)(i) of this chapter and § 90.672(a)(1)(i)
   shall apply;

   (ii) For channels 531 to 534--the minimum median desired signal level
   shall increase linearly from -80 dBm to -70 dBm;

   (iii) For channels 534 to 550--the minimum median desired signal level
   shall increase linearly from -70 dBm to -65 dBm.

   (l) Applicants may begin to license interstitial pool channels (denoted
   with an "a" after the channel number) listed in paragraphs (a) through
   (d) of this section only after the Wireless Telecommunications Bureau
   and the Public Safety and Homeland Security Bureau jointly release a
   public notice announcing the availability of those channels for
   licensing in a National Public Safety Planning Advisory Committee
   region.

   (m) Incumbent licensees in the 470-512 MHz band in the urban areas
   specified in § 90.303 of the Commission's rules are given priority
   access over mutually exclusive applicants for a three-year period to
   all interstitial channel pairs in the public safety pool or the
   business/industrial/land transportation pool listed above for which
   they are eligible, provided that any relocating T-Band incumbent must
   commit to surrendering an equal amount of 470-512 MHz spectrum on a
   channel-for-channel basis. The three-year period begins on the date
   these channel pairs become available for licensing in a National Public
   Safety Planning Advisory Committee region. Priority access applies to
   any applicant seeking to license a base station within 80 kilometers
   (50 miles) or mobile units or control stations within 128 kilometers
   (80 miles) of the geographic center of the urbanized areas listed in
   § 90.303 of the Commission's rules.
