what does quad-band mean?
580277
It means that the phone can access 850, 1900, 900 and 1800 MHz bands so that it can operate in the U.S. and other parts of the world such Europe and Asia. Hope this helps.

I belive that International phones use a differant band then USA phones, this one can be used internationally if it is unlocked and you can put a sim card in it. I am really not that sure but I think that is the general idea concerning band.

It is fine to have them all in the same frequency band. I have 4 running in the same band with no issues.

I think you are out of luck.In Wi-Fi wireless networking, dual band is the capability to transmit on the 5 GHz band of 802.11a and also the 2.4 GHz band used by 802.11b, 802.11g, and 802.11n. Unlike ordinary Wi-Fi equipment that only supports one signal band, dual-band gear contain two different types of wireless radios that can support connections on both 2.4 GHz and 5 GHz links. The cameras operate 802.11 g and n which is the 2.4 ghz band

It should work outside the US since it is a quad band, quad band pretty much covers the 5 or 7 seven continents (depending who you ask), which basically covers the whole world where there are signals of course.

It's an external WiFi antenna which utilizes one (or optionally two) USB ports at the computer. Two connections theoretically provides enhanced band-width. I use it at home where one computer is at near max wireless range and in an RV when using a laptop. Works quite well for me.... Doubles the reception bars in most instances.

Hi Blackspade.The only thing that I know is: RM820 is the North American variant. Has pentaband UMTS (850/900/1700/1900/2100) and North American LTE bands. RM821 is rest-of-world (except China). Has quadband UMTS (850/900/1900/2100) and European LTE bands. China, with no 100% sure, is RM822 and specific to this country.I hope I have helped you.

That signifies the frequency of the wireless. If you are using more than one wireless at the same time at the same location they need to be different frequencies. If you visit the Samson website, you can find out exactly what frequency each one is at. Generally, unless you are using two or more at once, it shouldn't make much difference to you. However, due to interference from DTV and other RF (radio frequency) sources in your area--one might work far better than another. Determining interference in advance is complex and would take a review of FCC data bases along with a bit of wizardry. The best approach (the one I took), is to buy it and see if it works in your area. To test, turn on the reciever and turn up the volume--listen on headphones for any interference...then turn on the transmitter and see if you hear any problems. If all is clear, you are good to go. If you hear intermittent hisses and fps, return the unit and order a different channel.

This one is better, because it is Quad (4x) shielded. The other is Tri (3x) shielded.

Es Quad-Band 850 / 900 / 1800 / 1900 MHz, asi que funciona con todas las operadoras.

Hi Daniel Fajardo V!! This Phone isn't Quad-Band. I8190L ("L") is 850 / 1900 / 2100 MHz 3G/HSDPA and I8190 is 900 / 1900 / 2100 3G/HSDPA. If you use 3G/HSDPA 1900 MHz any work you. The most common is the Latin American version I8190L. The Quad-band is GSM

Dual band basically means the router broadcasts two networks. So you can have one for downloading, and one for regular use. Or one for guests and other locked by password. At my house, my tv is connected to one band, and my computer to the other. It helps with streaming. This is an okay router. I had an awesome Belkin before so I got another one. I'm not in love with it, but it stays connected and was super easy to set up. It seems like it could be faster but, that could be an internet problem also. I would buy this router again for the price. Belkin is reliable, so I didn't want to chance any unknown brands. Dual band basically means the router broadcasts two networks.

Yes...it is quad band and unlocked; hard of hearing....well, this phone can support either a wireless bluetooth or a wired headset w/mic (both which Amazon has great deal on). Overall, its a great all-around phone!!

I have a dual-band router... the Asus "Dark Knight" router (a VERY nice router). It has both 5.0 and 2.4 bands on "n" wireless. My BD device only sees the 2.4 band. In fact, I only have a couple of devices which can see my "5.0" channel. In those cases, I always connect them to the 5.0 band, because it's so seldom used otherwise.

http://www.avsforum.com/t/830877/quad-shield-or-not Appears to be some differences in opinion as to the differences in the shielding. Here is a reference to a discussion -- should give you a little guidance amongst the confusion - -

Mine is Quad band as well. I have no problems using it in my carrier's HDSPA+ network here in Colombia. Still it would be great if European users can give a hint about hot it works in their frequencies

Both it will pretty much burn anything from cdrs to bluray mdiscs, I believe it is quad layer capable.
