What frequency is used in GSM?

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.

What is GSM 900MHz and 1800MHz?

An increasing number of studies find that pulsed Radio Frequency (RF), electromagnetic radiation of both systems of digital mobile telephony, established and commonly used in Europe during the last years, GSM 900MHz (Global System for Mobile telecommunications) and DCS 1800MHz (Digital Cellular System), exert intense …

Does Ghana use GSM or CDMA?

Ghana currently has six mobile phone network providers who all operate on GSM except one which has deployed CDMA. The six networks are Mobile Telecommunications Network (MTN), Airtel, Tigo, Vodafone Ghana, Glo Mobile, and Expresso.

What is frequency refarming?

“Refarming” is the term used for the process governing the. repurposing of frequency bands that have historically been allocated for 2G mobile services (using GSM technology) for new generation of mobile technologies, including both third generation (using UMTS technology) and fourth generation (using LTE technology).

What network does Ghana use?

Mobile Data (February 2017)

What is the difference between GSM and LTE?

GSM supports both voice calls and data. Whereas it is used only for high speed data communication. In GSM, two frequency bands are used 900 MHz and 1800 MHz. Whereas in LTE, frequency bands from 1 to 25 and from 33 to 41 are reserved for FDD( Frequency Division Duplex) and TDD(Time Division Duplex) respectively.

What carrier aggregation means?

Carrier Aggregation (CA) is a feature of LTE-Advanced that allows mobile operators & devices to combine two or more LTE carriers into a single data change. Carrier Aggregation is a technique that combines multiple frequency bands to offer you more bandwidth which results in faster data speed.

What is frequency refarming in mobile network optimization?

Refarming is a cost-effective way to increase capacity for UMTS/LTE without the need to bid for new spectrum. Compared to networks using the 2100 MHz core-band 3G spectrum, costs can be 50 to 70% less. Operators can provide less densely populated areas with 3G services more cost-effectively.

What is GSM and why is it important?

GSM was developed using digital technology. It has an ability to carry 64 kbps to 120 Mbps of data rates. Presently GSM supports more than one billion mobile subscribers in more than 210 countries throughout the world. GSM provides basic to advanced voice and data services including roaming service.
