What frequency is Wcdma?
What frequency is Wcdma?
Wideband CDMA is a third-generation (3G) wireless standard which utilizes one 5 MHz channel for both voice and data, initially offering data speeds up to 384 Kbps. WCDMA was the 3G technology used in the US by AT and T-Mobile.
How is frequency allocated?
ITU definition The International Telecommunication Union defines frequency allocation as being of “a given frequency band for the purpose of its use by one or more terrestrial or space radiocommunication services or the radio astronomy service under specified conditions”.
What is frequency band of 3G?
Most 3G networks operate in the 800 MHz, 850 MHz, 900 MHz, 1,700 MHz, 1,900 MHz and 2,100 MHz bands. “The 3G networks eventually led to a dramatic growth in the use of mobile data, initially through USB dongles connected to laptops, and later through widespread smartphone adoption.”
What are the frequency bands allocated for UMTS?
The specific frequency bands originally defined by the UMTS standard are 1885–2025 MHz for the mobile-to-base (uplink) and 2110–2200 MHz for the base-to-mobile (downlink). In the US, 1710–1755 MHz and 2110–2155 MHz are used instead, as the 1900 MHz band was already used.
What is WCDMA 3G?
WCDMA (Wideband Code Division Multiple Access) UMTS standard for 3G digital mobile networks, using CDMA technology. It is the evolution path for GSM and EDGE to UMTS and offers increased voice capacity and theoretical peak data speeds of up to 2 Mbps.
Is Wcdma 2G or 3G?
WCDMA is the 3G network that uses radiofrequency to transfer data in the form of calls, messages, or the internet which is also called UMTS. GSM represents 2G networks that were developed way before WCDMA and helps to transfer data through radio technology in the system.
What are the frequency bands of UMTS / WCDMA?
The main UMTS / WCDMA frequency bands for FDD operation are summarised below: Frequency bands 15, 16, 17, 18, 23 and 24 are now reserved frequency bands. The main UMTS frequency bands for TDD, time division duplex, operation are summarised below. It is also noted that several of the UMTS frequency bands overlap or share similar frequencies.
What is the WCDMA 2100 MHz?
Authorities opted to introduce WCDMA in the UMTS core band at 2100 MHz, a frequency reserved for IMT-2000 technologies. This put WCDMA at a disadvantage in these markets, and GSM long remained the dominant technology for the 900 MHz band.
What is WCDMA frequency refarming and how does it affect 3G?
To date, 3G coverage over large areas has been an expensive proposition, stalling efforts to bring broadband mobile data services to far-flung customers. Now there is a viable solution to this cost problem: Using 3G over the 900 MHz spectrum band – that is, WCDMA frequency refarming – can afford people access to more sophisticated mobile services.
What is the frequency allocation and bandwidth for CDMA in India?
As India is a large country, the licensing regime for India is available in circles. So, the frequency allocation and the bandwidth differs circle by circle. Operators like Reliance Communication, MTS, BSNL, and Tata have very fewer CDMA subscribers. For CDMA technology, the frequency band used in India is 850 MHz.
