What is the difference between GSM and DCS?
GSM is the short form of Global System for Mobile Communication. DCS is the short form of Digital Communication System. PDC is the short form of Personal Digital Cellular standard.
What is difference between 900mhz and 1800MHz?
It has been proven that 900 Mhz band has 30-40 per cent better coverage than 1800 Mhz band. To make up for this, mobile companies on 1800 Mhz have to invest more in setting up larger number of base stations to achieve the same coverage as in the 900 Mhz band.
What is carrier spacing in GSM-900 DCS 1800?
GSM-900 and GSM-1800 are used in most of the world. GSM-900 uses 890 – 915 MHz to send information from the Mobile Station to the Base Transceiver Station (BTS) (This is the “uplink”) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels spaced at 200 kHz. Duplex spacing of 45 MHz is used.
What is dcs1800?
Digital Cellular System 1800MHz. Digital Cellular System 1800MHz is a term given to what is now known as GSM1800. This system operates in the 1800MHz region of the frequency spectrum. The paired spectrum is located between 1710MHz and 1785MHz for uplink operation and 1805MHz and 1880MHz for downlink operation.
What band is 900 MHz?
The 33-centimeter or 900 MHz band is a portion of the UHF radio spectrum internationally allocated to amateur radio on a secondary basis. It ranges from 902 to 928 MHz and is unique to ITU Region 2. It is primarily used for very local communications as opposed to bands lower in frequency.
What is GSM 900MHz and 1800MHz?
Introduction. The two systems of digital mobile telephony radiation commonly used in Europe, GSM 900MHz and DCS 1800MHz, differ in the carrier frequency, (900 and. 1800MHz, respectively), while both use the same pulse repetition frequency of. Address correspondence to Dimitris J.
What is GSM DCS?
Digital Cellular System. Also known as “GSM 1800”, DCS is a radio frequency band used in Europe, Africa, Asia, and South America for GSM mobile phones. DCS bands are 1710-1785 MHz and 1805-1880 MHz. There are at least five licensed sub-bands within that range in most countries that have DCS.
Who uses the 900 MHz band?
The 900 MHz band is currently designated for narrowband land mobile radio communications and primarily used by land transportation, utility, manufacturing, and petrochemical companies.
