Re: Digital vs Tri-mode phones?
A tri-mode phone uses both the cellular frquencies AND the Analog portion as its full spectrum. On both TDMA and CDMA. So a TDMA Tri-mode will work on 800Mhz,1900Mhz and Analog and a CDMA Tri-mode will work on 800Mhz or 1900Mhz and Analog.
Does the Tri-modes get better reception than the dual modes or strictly digital ? Sometimes. If you get into an area where the only signal available is Analog or an area where there is a 1900Mhz signal stronger than an 800Mhz, well then yes. Your phone will utilize that extra capability to pull in that extra signal. Now this also has a HUGE amount to do with how optimized your network is and blah blah blah...
But essentially, a tri-mode phone CAN make use of a bigger frequency range than a regular "DIGITAL" (only two frequencies - either both digital or one digital and one analog).
Hope this helps.
