Cellular FAQ Table of Contents
What is the difference between "Digital" and "Analog"?Analog service (AMPS) has been around for many years. Chances are, if you have had cellular in the past, it's been an analog service. Digital technology allows cellar providers to place more calls on each tower by dividing up the signal into "packets." Since more people can "fit" onto a tower, cellular providers can offer lower rates or more packaged minutes. Back to TopWhat are TDMA, CDMA, GSM, iDEN, and PCS?TDMA (Time Division Multiple Access): Divides the cellular signal into packets based on a time algorithm. CDMA (Code Division Multiple Access): Divides the cellular signal into packets based on a code. This is the newest technology available in this area. CDMA phones don't have the "digitized" sound quality that TDMA phones are infamous for. Additionally, CDMA has the potential to carry twice the capacity of TDMA. GSM (Global System for Mobile communication): GSM phones use a TDMA technology. This is the most common system used overseas (Europe and Asia). iDEN (Integrated Digital Enhanced Network): Used exclusively by NEXTEL phones. iDEN phones operate on a specific TDMA architecture. PCS (Personal Communication Services): PCS can stand for any wireless personal communication service (cell phone, pager, PDA). It is most commonly identified with high frequency (1.9Ghz) CDMA cellular service. Back to TopWhat's the difference between NiCAD, NiMH, and LiON?Nickel Cadmium (NiCAD) batteries are the least expensive, but most common battery. For optimum performance, NiCAD batteries should be completely discharged before being recharged, and then be recharged for a full eight hours at a time. Failure to properly discharge / recharge a NiCAD battery can lead to diminished performance (i.e. the "memory" effect). Nickel Metal Hydride (NiMH) batteries will resist the "memory" effect; allowing the user to charge their battery whenever is convenient. Cellular Concepts tries to stock NiMH batteries for every phone they sell. We sell NiCAD and NiMH batteries at the same low price! Lithium Ion (LiON) batteries are also resistant to retaining a "memory," but normally provide a longer stand-by and talk time and less weight than their counterparts. LiON batteries are slightly more expensive than NiMH. All digital phones sold by Cellular Concepts come equipped with a LiON battery Back to TopHow should I charge my batteries?New batteries should be charged 18-24 hours before first use. Users with NiCAD batteries are encouraged to completely discharge their batteries before recharging them. This can be done by letting the phone stay on until it dies, or by purchasing a desktop charger that will discharge the battery before recharging it. NiCAD batteries should be charged for a full eight hours at a time. NiMH and LiON batteries can be charged at any time and for any length of time. Back to TopHow long should my batteries last (life)?Battery "life" is approximately one year, however charging habits may extend or reduce the life of your battery. Back to TopHow long should my batteries last (per use)?Standby time: Standby time is when the phone is ON, but not "IN USE." Standby times vary from phone to phone and are dependent upon type of battery (NiCAD, NiMH, LiON), type of phone, and individual charging habits. Talk time: Talk time is when the phone is IN USE. Again, times are vary with batteries, phones, and charging habits. A simple rule of thumb: Back to TopWill my car charger hurt my phone's battery?Car chargers are a great way to keep you talking during a busy day or on an extended trip; however, using the car charger for more than two hours at a time can "burn-up" your battery. We recommend that you only use your cigarette charger for charging a low battery and never for more than two hours at a time. Back to TopWhat is roaming? How much is roaming?Roaming is traveling outside your normal service area. Roaming charges depend on your cellular provider and/or the service provider in the area you are roaming in. NEXTEL has no roaming charges. Verizon and SunCom both offer plans that include roaming and/or long distance. Back to TopWhat about long distance?Long distance charges vary from company to company. Long distance charges while roaming vary according to where you placed the call. You can expect to pay roaming AND long distance charges if you place a long distance call while outside your local service area. Verizon and SunCom both offer plans that have no long distance charges. Back to TopWhat is my local service area?Local service areas vary between companies and even rate plans. Visit your nearest Cellular Concepts store to find the service that best suits your coverage needs. Back to TopWhat phones have the best reception / most power?All handheld cell phones are limited to .6 of one watt. Back to TopHow can I track how many minutes I'm using?Most cell phones have internal timers that track the amount of time elapsed per phone call. See you users manual or stop by any of our stores for specific information about how to find and reset the minutes for your phone. Back to TopHow are my minutes billed?Most cellular companies bill in one minute increments. NEXTEL bills in one second increments AFTER the first minute. Back to TopWhy does the timer on my phone show a different total than my bill?#1: Timers on phones count the time between the SEND and END key presses. If
you call a number and there is no answer or it is busy, your bill will not reflect this
time but your call timer will. #2: If your call timer tracks minutes and seconds, it is not rounding
calls up to the
next minute - the cellular company does (except NEXTEL). Back to TopIf I switch cellular companies, can I keep my same number?No. Your current cellular provider owns your cellular number. Our friendly and knowledgeable representatives can offer other solutions to ensure that your current callers are able to follow your number change. Back to Top |
