What network is iPhone 5s?
4G networks
The iPhone 5 and iPhone 5S support 4G networks, but don’t have native support for VoLTE. Similarly, all other devices that don’t support VoLTE will be rendered useless for now.
What is the difference between WCDMA and CDMA?
WCDMA stands for Wideband Code Division Multiple Access. It basically uses the same technology as that of CDMA but incorporates it into 3G. This works with GSM and EDGE to be used as UMTS and also resulted in higher internet speed. WCDMA signifies the leap from 2G to 3G and thus is miles ahead in terms of speed.
What is the difference between narrowband and CDMA?
When we consider the CDMA system design, multiple access and interference handling are totally different from the narrowband systems. In CDMA, each user spread his signal over the entire bandwidth using the direct sequence spread spectrum, whereas for other users, it is shown as pseudo white noise.
What is the bandwidth of a WCDMA signal?
WCDMA uses 5MHz, 10MHz or 20MHz channel bandwidth to send the data signals over the air interface. WCDMA mixes original signal with a pseudo random noise code, which is also known as Direct Sequence WCDMA. Therefore, each user ends up with a unique code, where only users with correct code can decode the message.
What is the mode of operation of CDMA?
However, one should not confuse the mode of operation of CDMA with the usual methods of time and frequency multiplexing. This is because, in CDMA, a customer is able to access the network for the whole duration, without any supposed interruptions.
