the FCC rules, including frequencies in the 72-76 MHz band as well as the usual 30.56-49.58 MHz, 150.775-162.000 MHz VHF bands and the 450-470 MHz band (plus 421-430 or 470-512 MHz in certain cities). In larger metropolitan areas with congested frequency spectrum, paging services will often share the same frequency as land mobile stations, or operate on an adjacent channel. For example, a department store may operate handheld walkie-talkies on 462.7625 MHz while there are high power pager transmitters on 462.7500 MHz and/or 462.7750 MHz in the same city. Or, a restaurant will use 467.7500 MHz to alert customers when their table is ready (using so-called "coaster pagers") while a department store nearby uses 467.7500 MHz for their in-store communications. In both of these examples, the department store is forced to use a squelch system such as CTCSS or DCS. In many areas in the United States, these frequencies are used for land mobile (two-way) radio communications services in addition to paging. The VHF (152/157-158 MHz) and UHF (454/459 MHz) frequencies are often used for a mixture of paging and land mobile communications. The VHF low band (35/43 MHz) frequencies are mainly used for local hospital paging and in many areas are completely unused.
