What is the difference between GSM 900 and GSM-1800?
GSM 800 (or 850) is simply GSM at 800 Mhz (or 850). aka 2G. The GSM 900 would simply be 900 MHz, if it exists. As far as I know, the current bands skip from 800 to 1900, aka 3G.
What is difference between 900mhz and 1800mhz?
Spectrum at 1800 MHz is used to provide additional capacity for the GSM900 based network while 900 MHz frequencies allow the GSM1800 based operator to provide more cost-effective coverage when rolling out beyond the 98% coverage point.
What is GSM 850 900 1800 1900?
A single-chip quad-band (850/900/1800/1900 MHz) direct conversion GSM/GPRS RF transceiver with integrated VCOs and fractional-n synthesizer. The transmit section is comprised of a quad-band up-conversion transmit phase-locked loop (PLL) including on chip transmit voltage-controlled oscillators (VCOs).
What band is 1800 MHz?
Band 3
Band 3 (1800 MHz): The most popular global band for LTE Far more LTE networks have been deployed at 1800 MHz (band 3) than in any other frequency band. Band 3 is now widely used throughout Europe, APAC, MEA and is also deployed in selected countries in South America. It has become a core band for LTE deployments.
What does quadband mean?
Mobile device that supports voice and data communications conforming to one bearer technology, such as GSM, but on four different sets of frequencies.
What is the difference between GSM 850 and GSM 1900?
GSM-1900 and GSM-850 are used in most of North, South and Central America (ITU-Region 2). In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band.
What is the difference between the 1800 and the 900 bands?
The lower bands are very attractive to telcos because the radio signal transmits very well. 900 is factor 4 more efficient than 1800: a network that operates in 1800 needs about 4 times the number of base stations to achieve the same area coverage as a 900 network.
What is the frequency range of the GSM-900?
GSM-900 uses 890–915 MHz to send information from the mobile station to the base station (uplink) and 935–960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used. Guard bands 100 kHz wide are placed at either end of the range of frequencies.
What is GSM-1900?
In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the “1900 MHz band”.
