What is WCDMA in network?

What is WCDMA in network?

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.

How does WCDMA work?

As an air interface technology, WCDMA is able to artificially increase a signal’s bandwidth. It does so by modulating each baseband symbol with a binary or quaternary signature with a much higher rate than that of the original data symbol.

What is the use of WCDMA?

(Wideband CDMA) A 3G cellular technology that uses the CDMA air interface. WCDMA works on WCDMA cellphones as well as laptops and portable devices with WCDMA modems. Falling under both the UMTS and IMT-2000 umbrellas, WCDMA enables GSM carriers to provide a higher data rate than the EDGE network.

Is WCDMA and UMTS the same?

Key Differences between UMTS vs WCDMA Though both are developed for mobile communications in the 3G network, UMTS is developed for 3G networks alone, whereas WCDMA is developed for 3G networks and 3G+ networks. When we consider WCDMA, it is based on GSM to make the coverage for 2G and 3G.

What is WCDMA vs CDMA?

The main difference between WCDMA and CDMA is that they are designed to work with different networks. WCDMA is a 3G technology designed to work alongside the 3G GSM network. CDMA, on the other hand, is a 2G technology that is a direct competitor to GSM.

Does Verizon use WCDMA?

Some people mistakenly think that WCDMA phones work on CDMA networks but this is NOT true; WCDMA and CDMA are two entirely different th… see more. In the US, Verizon and Sprint use CDMA technology while AT and T-Mobile use GSM. The acro S is a quad band GSM/WCDMA phone so it will NOT work with the Verizon network.

Which is better GSM or WCDMA?

The efficiency and speed are better in WCDMA due to the technology used in the network and the coding channel separating the data columns in the system. This helps to manage the communication channel well in the network and the communication is done faster than GSM. The efficiency and speed are less in GSM.

Which is better CDMA or WCDMA?

WCDMA is also better suited for accessing the internet and emails compared to the very slow CDMA. As indicated by the word wideband, WCDMA uses a much wider bandwidth than that of CDMA. WCDMA uses frequency bands that are 5Mhz wide compared to CDMA where each frequency band is only 1.25Mhz wide.

What is the cheap rate of WCDMA?

Explanation: W-CDMA uses a chip rate of 3.84 Mcps.

What is the WCDMA chip rate?

Explanation: W-CDMA uses a chip rate of 3.84 Mcps. Chip rate is the product of symbol rate and spreading factor.
