What is CDMA mode on Android?

CDMA or Code Division Multiple Access is a mobile communication standard that uses radio communication technology. Many transmitters can send information through a single channel, and there will not be any communication problem between them. Multiple users can share the same band of frequencies.

What does Network mode LTE WCDMA GSM mean?

auto connect
If you select LTE/GSM/WCDMA (auto connect), your phone automatically switches between the three network modes provided that you’re within range of a 4G network. If you select GSM only, you can’t achieve high data speeds. If you select WCDMA only, your phone can only connect to 3G networks.

Which is faster 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.

When to use GSM only or WCDMA mode?

GSM only – 2G only mode. When 2G signal strength is low, you get no data. WCDMA only – 3G only mode. When 3G signal strength is low, you get no data.

How to auto switch between GSM and CDMA?

GSM/CDMA auto (PRL) – auto-switching between GSM and CDMA capabilities. In a nutshell: GSM = 2G, WCDMA = 3G. For auto-switching between 2G/3G modes, use the “GSM/WCDMA auto” mode (system balances speed vs battery use based on current signal strength). For 2G-only battery saving mode, use “GSM only”.
