What frequency band do mobile phones use in the US?
Two UK mobile phone networks (T-Mobile and Orange) use a standard known as GSM1800. This uses a frequency of about 1800MHz.Two UK mobile phone networks (O2 and Vodafone) use a standard known as GSM900. This uses a frequency of about 900MHz.
What companies make quad band mobile phones?
Large international companies like Apple and Nokia usually sell quad band mobile phones, because quad band mobile phones can be used everywhere in the world.
What is the uplink and downlink frequency in 2100 band?
In the CDMA technology It is either between your Handset and the Mobile Station. The dedicated frequency are allocated for u sending your data to the mobile station (Uplink freuency) and a dedicated frequency is reserved for you to receive your data from the mobile station (Downlink frequency)
What frequency do mobile phones use in NZ?
New Zealand uses GSM 2G 900/1800 3G 850, 3G 900/2100 AFAIK NZ is in the process of phasing out their aging CDMA networks as is many other carriers around the world.
How does a mobile send and receive sound?
Mobile phones, like radios, transmit digital electronic signals that are converted back into sound at the receiving end. For cell phones, the transmission is in the UHF (Ultra-High Frequency) band, hence very limited in range compared to CB bands and broadcast radio. The frequencies for civilian phones and data transmission are discrete blocks ranging between 700 to 2700 Mhz.
What type of wave that are used by mobile phones?
Cellular phone signals are carried by radio waves, which are like visible light waves only much slower and longer. Commonly used frequencies are between 800 and 900 megahertz, but some phones use frequencies as high as 2 gigahertz.
What countries are using quad band?
Europe and Asia use dual-band through quad-band phones that are at the minimum able to operate in the GSM 900 and/or 1800 frequency bands. In North America (at least those that are carrier-based) are predominantly only dual-band phones, are in GSM or CDMA bands, and are SIM-locked.
What are the differences between dual band and quad band phones?
Basically, the difference lie on the frequency being used or supported. For GSM dual band phones, the frequencies that is can support are 900/1800 MHz or 850/1900 MHz; for tri-band phones, the frequencies are 850/1900/2100 or 850/1700/2100 or 900/1900/2100 MHz or 900/AWS/2100; and for quad-band phones, the frequencies are 850 / 900 / 1800 / 1900
Why doesn't North America use the 1800MHz frequency band for cell phones?
It may be that the 1800MHz band in the states is used by military or government departments. In the UK, it's used for radio-astronomy and other services.
Can you use a mobile phone with dual band 900 and1800 in Europe and usa?
Nope - you would need a quad band handset. The UK uses frequency bands 900 & 2100 MHz - whereas america uses frequency bands 850, 1700 & 1900 MHz.
What is an electronic communication sent and received by mobile phones?
They are sent the same way as radio and TV communication do. Through electromagnetic waves, with a high frequency band. The difference is that cell towers of transmission are necessary because the battery of a mobile has no enough power to send signals at a great distance. As a cell-phone user drives down the street, the signal is handed from tower to tower.
Can you use phones from another country?
In this answer, "phones" means "wired telephones", as opposed to wireless (cell) phones. (See below for information about mobile phones.)Generally yes, but the ringing or volume may be wrong. Some countries have laws about exactly what specifications a phone must have in order to be connected to the phone system.I have experience with Belgian electronic and Russian non-electronic phones connected in the USA. They both worked, but the ringing was very harsh on both, and the Belgian phone's volume was much too loud and it would feedback at times.These differences occur because of the voltages used by the phone system to operate the phones are different around the globe. This is to clarify: The phone gets its power to ring and to comunicate from the phone line.In the USA, which uses generally higher ringing and line voltages, you might be able to tweak your phone to operate perfectly by placing a resistor in series with the ringer and a resistor in series with each line (is always a pair) to the speech network inside the phone, if the ringing or speech is too loud. I did not try this, I just stopped using the out-of-country phones.For a mobile phone (cell phone), you can use a phone from another country if it uses a compatible frequency band. Many mobile handsets are "dual-band" or "multi-band," allowing them to be used in more countries. If you are planning to travel abroad with a mobile phone, check with your mobile service provider (cellular company) before you leave to see whether your phone will work in the country you will be visiting, and what the roaming rates will be. Alternatively, if your mobile uses a SIM card, you may be able to plug your SIM card into a handset that operates on the appropriate frequency band. It is possible to rent a handset for that purpose.
