It depends where you're intending on using the phone. Unless you're planning a world-wide cruise - a dual-band one would be perfectly adequate.

Can a quad band be used with metropcs?

Quadband phones run on GSM technology. Metropcs run on CDMA technology. These two technologies are not compatible with each other since they operate on different frequencies.


Where is EGSM 900 used?

GSM, or Global System for Mobiles , are a standard set of frequencies where hand held devices such as cellular phones can work on. For a typical tri-band device, the range of frequencies it will be compatible with are GSM900Mhz, GSM1800Mhz,and GSM1900Mhz. At some point in time, a range of extra spectrum was added to the 900 band and the EGSM900Mhz was born with E to mean Extended. EGSM900Mhz is used everywhere around the world except for the United States and Canada.


What is amplifier pass band in coupling?

A: An amplifier while capable to amplify a whole range of frequencies sometimes some of this frequency are not needed or wanted in a specific range or [BAND] so it is designed to either pass this band or reject this band of frequencies.


What is pass band and stop band?

The pass band is the range of frequencies that a filter allows to pass through with minimal attenuation, while the stop band refers to the range of frequencies that are significantly attenuated or blocked by the filter. In other words, the pass band is where signals can pass effectively, whereas the stop band contains frequencies that the filter suppresses. Together, these bands define the filter's frequency response characteristics.


What are the differences between the L band and S band frequencies in terms of their applications and characteristics?

The L band and S band frequencies differ in their applications and characteristics. The L band is lower in frequency and is commonly used for satellite communications and navigation systems. It has better penetration through obstacles like buildings and foliage. On the other hand, the S band is higher in frequency and is often used for radar and weather monitoring. It has a shorter range but offers higher data transfer rates.


What is electronic filter?

Filter is an electronic device which passes specific frequency and attenuates all other.There are 4 types of filters: 1) Highpass - passes only high frequencies 2)Lowpass - passes only low frequencies 3)bandpass-passes only specefic band of frequencies 4)band reject-passes all frequencies excepting desired band

Does your cell phone need to be quadband for cellular one?

I was told just yesterday that you do, I bought a cell phone from eBay and it wouldn't work w/ cell one and they said its b/c it has to be quad band.


Band is to frequency as spectrum is to?

Bandwidth. Bandwidth refers to the range of frequencies over which a signal or device can operate effectively, similar to how band refers to a specific range of frequencies in a spectrum.


What is the order of the electromagnetic spectrum in frequency?

I'm not sure what you intended to ask, but the frequency of electromagnetic radiation increases as the positive real numbers: from approaching the limit of zero Hz at the low end to approaching the limit of infinite Hz at the high end.Parts of this complete spectrum of frequencies have been given names:Extremely Low Frequencies - 3 Hz to 30 HzSuper Low Frequencies - 30 Hz to 300 HzUltra Low Frequencies - 300 Hz to 3 kHzVery Low Frequencies - 3 kHz to 30 kHzLow Frequencies - 30 kHz to 300 kHzMedium Frequencies - 300 kHz to 3 MHzHigh Frequencies - 3 MHz to 30 MHzVery High Frequencies - 30 MHz to 300 MHzUltra High Frequencies - 300 MHz to 3 GHzSuper High Frequencies - 3 GHz to 30 GHzExtremely High Frequencies - 30 GHz to 300 GHzTremendously High Frequencies - 300 GHz to 3 THzInfra Red - 300 GHz to 430 THzVisible Light - 430 THz to 790 THzUltra Violet - 790 THz to 30 PHzX-Rays - 30 PHz to 30 EHzGamma Rays - 30 EHz and upAll frequencies below 3 THz can also be called Radio Waves because they can be used for various types of Radio communication and related applications.NATO divides Radio Waves into the following bands:A band - 0 Hz to 250 MHzB band - 250 MHz to 500 MHzC band - 500 MHz to 1 GHzD band - 1 GHz to 2 GHzE band - 2 GHz to 3 GHzF band - 3 GHz to 4 GHzG band - 4 GHz to 6 GHzH band - 6 GHz to 8 GHzI band - 8 GHz to 10 GHzJ band - 10 GHz to 20 GHzK band - 20 GHz to 40 GHzL band - 40 GHz to 60 GHzM band - 60 GHz to 100 GHzIEEE divides Radio Waves into the following bands:High Frequencies - 3 MHz to 30 MHzVery High Frequencies - 30 MHz to 300 MHzUltra High Frequencies - 300 MHz to 1 GHzL band - 1 GHz to 2 GHzS band - 2 GHz to 4 GHzC band - 4 GHz to 8 GHzX band - 8 GHz to 12 GHzKu band - 12 GHz to 18 GHzK band - 18 GHz to 27 GHzKa band - 26.5 GHz to 40 GHzV band - 40 GHz to 75 GHzW band - 75 GHz to 110 GHzmm band - 110 GHz to 300 GHzThere are several other naming systems for the various parts/bands of the electromagnetic spectrum.
