	Do you need a Dual Tri or Quad Band GSM Cell Phone
		The actual frequencies in the band are closer to 850 MHz and the standardized naming convention as promulgated by the GSM Association is to refer to this band as '850 MHz'.
		Happily, nine months later, quad band phones have become a lot more common and may even be close to free when you're signing up for new service.
		If so, choose the three bands that best suit you based on whether you'll primarily be using the phone in the US or internationally.

	Quad band - Wikipedia, the free encyclopedia
		The GSM standard originated in Europe, where mobile phones occupy two frequency bands: one in the 900-MHz range and one in the 1800-MHz range.
		When GSM technology crossed the Atlantic to the Americas, it was impossible to reuse the same European frequency bands since those had already been allocated to other devices by the FCC.
		Hence, a different pair of frequency bands were made available for GSM use: the 850 and 1900-MHz bands.

	KS7J 5-band Cubex Quad (Site not responding. Last check: 2007-10-25)
		The LB quad was always a bit of a maintenance problem due to the less expensive construction (I got what I paid for!).
		Below are some shots of the quad during construction and up on the tower with a few pictures of construction details.
		Quads have great gain, are quieter, and have a lower take-off angle relative to a yagi of the same number of elements and same boom height.

	Modeling Multi Band Cubical Quad Antennas With EZNEC and MATLAB
		My current objective is to put up a five band quad by adding 17 and 12 Meter band wires to the four elements used on the 20 and 15 Meter quad arms.
		The first band declared in the matrix is the driven band such that the EZNEC 4.0 source wire #5 never needs to be changed.
		The plot scales on each band are the same such that a view graph of the five band plots could be laid over the tri band plots for direct visual comparisons.

	Quad Models
		One feature of quads constructed by this method is that the element spacing between the driver and the reflector is constant in terms of wavelengths.
		In the combined quad, the segmentation was selected to have--to the degree feasible--identical segment lengths throughout and segment junctions that aligned from one loop to the next.
		Although the 10- meter band is wider than the other as a percentage of the center frequency, the gain holds up better on that band than on the lower bands.

	Racal Instruments Offers Handset Manufacturers Choice and Flexibility in Quad Band Conformance Testing Platforms
		In short to develop a quad band phone can mean having to use two test systems, one for the 850/1900 MHz bands and a second configured for 900/1800/1900 MHz.
		To meet manufacturers' needs Racal's test platform with quad band test functionality in a single system gives the highest degree of flexibility allowing users to switch between different types of phone without reconfiguration quickly and easily.
		Therefore mobile phone manufacturers are now designing products for use in the 850 MHz band in addition to 900, 1800 and 1900 MHz bands and have already deployed to some network operators who have stated that they will not accept devices that do not have 850 MHz capability.

		The in-band insertion loss is measured as low as 1.2 dB in the 800/900 MHz band.
		Worldwide GSM has four bands: GSM 850 MHz and GSM 1900 MHz (Personal Communication Services, PCS) bands are used in America, while GSM 900 MHz and GSM 1800 MHz (Digital Cellular Services, DCS) bands are used in Europe and elsewhere in the world.
		At the low GSM band (GSM 800/950 MHz), the specified output power is 33 dBm, thus requiring better than —63 dBc rejection, while at the high GSM band (GSM 1800/1900 MHz), the specified power is 31 dBm, requiring better than —61 dBc rejection.

	Triband (telephone) - Wikipedia, the free encyclopedia
		Triband phones (also known as tri-band or tri-mode) are mobile phones that support the GSM 900/1800/1900 MHz bands (commonly sold in Europe, Asia, and Africa), or alternatively the 850/1800/1900 bands (commonly sold in the Americas).
		Various countries use different frequency bands for their mobile networks, and a tri-band phone can be used on three of these bands, generally speaking, chosen to favor two of the home country's bands, and one for roaming in other countries.
		A quad band phone will offer more coverage.

		Merging many of the critical valued RF capacitor, inductor and coupler functions into the IPDs significantly reduced the total number of in module components to offer a solution that is more efficient with smaller size and lower cost, stated Cliff Vaughan, Freescale's module methodologist.
		For receiver band noise, the performance is specified at -84 dBm/100 kHz for low bands, while for high bands it is -77 dBm/100 kHz.

		Seems some providers have problems with roaming if you are on the 850 band - your call initiates and then you sometimes get the message that the service is unavialble (I guess from you provider at home...).

	Debunk: sleep easy, the iPhone's still a quad-band worldphone - Engadget
		The fear basically revolves around the fact that a lack of testing on the GSM 900 and 1800MHz bands indicates that it lacks those bands entirely, but we can assure the globetrotters out there jonesin' for an iPhone come next month that there'll be a full range of RF spectrum waiting for you.
		However, Chris's argument that the FCC not testing or mentioning the non-US 900/1800 GSM bands on the Blackberry 8800, or any number of quad band phones, can somehow be used as a proof of those same bands being included in the iPhone is utter nonsense.
		Regarding the Quad Band discussion's: It is obvious that the average American cell phone user is not an educated one.
