Technical Articles by Charles Rhodes (TV Technology Mag) re Interference between DTV
and New Cell Phone Freqs in the so-called 700 MHz Band:

BTW: Ch51 might be helping by eliminating ADJACENT channel interference to Cell Phones,
but as Charles Rhodes points out, there can be significant NEXT ADJACENT
(N+/-1, 2, 3, 4, 5, 6, 7, etc) EMI...esp. anywhere near the DTV Antenna Farms....and
when/if even more UHF freqs are transitioned from DTV to Cell Phone usage, then
EVERY lower channel will be occupied, making it certain that IMD products will fall
on top of the even Newer Cell Phone which point, ALL DTV operations
will be encouraged to move to the VHF Band....just Ch2-13...minus Ch5+6 for FM????
