(From the November 2000 "Service Search" column by Larry Van Horn, MT Assistant Editor)
This month we are going to present the channel
plan for the 220-222 MHz land mobile band. In 1988 the FCC reallocated
220-222 MHz to the Private Mobile Radio Services from the 220-225 band used by
Amateur Radio. The principle requester was United Parcel Service which needed
radios for its business.
Since then the 220-222 MHz band has gradually
developed into spectrum devoted to narrowband voice (bandwidth less than 4 kHz).
This band has 200 channel pairs; 60 pairs are for nationwide use and 140 pairs
are for shared local use. Of the 60 nationwide pairs, 10 are for exclusive
government use and 50 are for exclusive non-government use. Of the 140 shared
local-use channel pairs, 100 are available for trunk or other operations of
equivalent or greater efficiency, 10 are available for public safety/mutual aid,
20 are indefinitely reserved until further FCC action and not available for
assignment, and the remaining 10 channel pairs have no restrictions on use.
Frequencies are assigned in pairs with base
station frequencies taken from the 220-221 MHz band, corresponding mobile
frequencies being 1-MHz higher, taken from the 221-222 MHz band.
