My question is does digital handoff to analog without a call drop actually work for any carrier? (It does not for Sprint, I guess since they have no AMPS of their own) Or is analog only a backup in case no digital signal can be found, but not there to take a handoff from a digital connection.
When switching from one carrier to another, I don't know of any. When using the same carrier, no problem. Hman
....."When using the same carrier, no problem."...... Then might this be the reason some people complain about Sprint PCS, the fact that they have no analog of their own, therefore no clean handoff?? Maybe users used to a provider that has both digital and AMPS in their own network are used to a clean handoff, so they don't realize how often they actually lose their digital signal? Just curious.
with Cingular TDMA, my phone (Nokia 3360) has occassionaly switched to AMPS while in a call; in these 2 or 3 instances (all in metro Dallas, I might add) the call was dropped.
In response to TKR: even if this so called clean handoff were possible between different carriers I don't think Sprint would implement it simply because their customers wouldn't know that they were roaming and therefore being charged extra. It would open the door for too many complaints, know what I mean?
Can you tell me why I should choose Sprint over Nextel? Any help in this decision of mine would be greatly appreciated!
I can't comment on Nextel because I've never used it but it's usually geared more towards businesses. I personally wouldn't use them because I don't need the two way radio feature and don't like their phones. Do they even offer service in Redding?
There new line of phones is nice. If you go nextel go with the i90 or i1000 (2nd choice) if you want a flip and if that does not matter to you go with the i85s Jack
When you are you switching tower the MTSO (Mobile Telephone Switching Office)contacts the Cell Site that closest to the area where you are traveling and the hand yo over to the one that's generating the strongest signal;it does matter if it digital or analog. That how some people roam sometimes in there on home area, because it picking up the other carrier signal.
well you are right about the first part, but your phone is programmed to scan your carriers freq. so you will not hand off to another carrier unless it is done by the MTSO.(Also your phone has to be capable of handing off to the other carriers freq. 800 or 1900 also tech. matters too) Which most carriers do not have multicarrier hand offs because you have to have a T1 beween the two carriers (MTSO) to facility the traffic hand off. It also doesn't work everytime when it is setup, which causes dropped calls. Also the hand off between Digital and AMPS does work pretty well intersystemly. But you do have to realize you phone has to rescan to a different freq. which leaves a chance of dropping a call ..... I don't know of a system that can hand AMPS back to CDMA, but you can hand AMPS back to TDMA. If someone know a system that can hand CDMA back to AMPS please reply. Lucent and Nortel can't ....
