Q:Hi i have been doing some research into mobile phones and i came across a few terms that really confused me, i understand that when you talk on the phone the data is converted from your voice into digital signals, the part i dont understand is where modulation such as PSK occurs and how TDMA and CDMA fits into all of this can someone tell me what the relation is between these things.thank you

There are a few parts to a mobile phone system: most obviously you have the radio interface, some kind of two way radio link between the handset and the 'base station'. This transmitts and recieves digital data using quadrature phase shift keying (PSK). This is a kind of modulation very similar to FM, but is used with digital signals rather than analogue signals. So the digital data is used to phase shift modulate an RF carrier which is then transmitted, and picked up by the base station, which then demodulates the PSK signal to recover the digital data. This is all very well and good, but what do we do when we have many users? How can the base station distinguish between the signal from one hand set and another? This is where Time Division Multiple Access (TDMA) and Code Division Multiple Access (CDMA) come into play. TDMA (used in GSM systems) is a kind of time division multiplexing. Each user gets a certain 'time slot' in which they are allowed to transmit their PSK signal in. So each user takes a turn and sends a few bytes at a time. In GSM there are 8 time slots (I think, i cannot recall exactly) in each channel (frequency). The bit rate is low and special vocoders are used to get voice audio into a low bit rate. CDMA works differently, on principles originated by an Austrian actor (and electrical engineer and mathematician!) Hedy Lamarr

Q:Hi. Lets try this again and see if anyone knows I recently upgraded to a new cell phone(an LG Dare with Verizon) and am now able to get into yahoo Messenger. My question is when I sign into Messenger using my mobile phone, is there a way to show myself asavailable to some of my contacts and not to the others at the same time? If so how do I go about showing myself online(mobile) to the few and not the others like one can do on the computer? Thank you so much in advance :)

yai totally agree with you man!

Q:I have a mobile phone, an LG CU515. For as long as I've had it, I've experienced disruption of service. At random parts of the day, in any weather condition, I will hear a slight beep, and then open my phone only to read, Smartchip not allowed MM#The phone isn't shutting itself off, I just can't make or receive any calls, or text messages. WhenI'm in the process of an Instant Message, I'm immediately signed out. I've found powering it off, and then back on, fixes the problem. I miss calls and texts if I don't have the phone around me, as I don't hear the slight noise that always sounds, when these distruptions occur. I always get the messages that are missed, once I power the phone off and on.I've had the phone for at least 4 months. I've talked to 4 different 'experts' at ATT, but they're clueless. I'm very simple. I don't ask for much, but this is quite bothersome. Can you advise?

I really cannot help you - I am somewhat technologically impaired! However, I starred your question, in the hopes that one of my contacts may be able to answer that for you.

Q:i dont want to resign for 2 years with nextel, but i need a new phone. if i buy a boost mobile phone ( looking at the i9 Stature) will i just be able to put in my nextel sim and it work? I have heard it will but it needs to be unlocked first, what does that mean?

sprint won't be in a position to take SIM taking area in enjoying cards, and the Nextel ingredient would not definitely use GSM service (they use some element comparable stated as iDEN) that's what your sim card is desperate up for. regrettably the quickly answer is 'NO' even with the essential actuality that the nextel telephone has the SIM card slot, it somewhat is honestly incompatable technologies. My apologies. want this helps!

Q:I am trying my luck for the one last time if T-Mobile right for me. the phone i have is motorala razr which really terrible- poor reception, dropped calls etc. any suggestion just a simple tmobile phone with good reception , that is all in needed
