It is common knowledge that the paging probability vs. signal strength performance of digital "%Ipha/Nu- meric" pagers is worst than the "Tone Only" pagers. One major reason is due to the "error correcting for- mat" chosen for the alpha message characters is not the same as the "address data" format. That is, more bits can be corrupted or missed in the pager's unique "address code" than it can in the "alpha message" and still alert the proper pager. The net result is that even though the pager's unique address is detected in a weak signal envi- ronment the user is not alerted if the alpha message is too corrupted for proper identification by the pager.
