How many carriers does GSM 900 have?

How many carriers does GSM 900 have?

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 the difference between GSM 900 and 1800?

The two types of cellular telephony radiation use different carrier frequencies and give different frequency spectra, but they usually also differ in intensity, as GSM 900 MHz antennas operate at about double the power output than the corresponding DCS 1800 MHz ones.

Is GSM 900 A 2G?

GSM networks operate in a number of different carrier frequency ranges (separated into GSM frequency ranges for 2G and UMTS frequency bands for 3G), with most 2G GSM networks operating in the 900 MHz or 1800 MHz bands.

What is HSPA network type?

HSPA (high speed packet access) is a third-generation (3G) mobile broadband communications technology. HSPA networks offer a maximum of 14.4 megabytes per second (MBps) of throughput per cell. An improved version of high speed packet access technology, known as Evolved HSPA, offers 42 Mbps of throughput per cell.

Is the GSM 900 the same as EGSM?

EGSM extends the frequency bands of GSM 900 giving it added network capacity. Most new phones listed as GSM 900 also support EGSM.

Why do I need an EGSM cell phone?

A small radio frequency band used in Europe to provide added network capacity for GSM 900 networks. If you are using one of the European GSM carriers that uses EGSM, then using an EGSM phone may improve coverage and/or reduce “network busy” messages.

Where are GSM 900 and 1800 frequency bands used?

A dual-band 900/1800 device is required to be compatible with most networks apart from deployments in ITU Region 2. GSM-900 and GSM-1800 are used in most parts of the world (ITU-Regions 1 and 3): Africa, Europe, Middle East, Asia (apart from Japan and South Korea where GSM has never been introduced) and Oceania .

Can you use P GSM and E GSM in the same BTSs?

An additional possibility to increase the capacity of a classical GSM 900 network is offered by the extended GSM 900 band. Standard (P-GSM) and extended (E-GSM) frequencies are used in separate BTSs. With nokia it is not possible to use TRXs of both bands within the same BTS. Tri band must be supported by the MS as well.
