LTE is commonly marketed as 3G and VoLTE is commonly marketed as advanced 3G.<br/>2. LTE is data-only technology and VoLTE is voice-only technology.<br/><br/>Select the correct answer using the code given below.
Answer
Neither 1 nor 2
1. Incorrect. LTE is generally marketed as 4G, not 3G. VoLTE is not “advanced 3G”; it is voice service delivered over a 4G LTE network.
2. Incorrect. LTE is primarily a packet-switched data network, but VoLTE is not voice-only technology; it is a method of carrying voice calls as data packets over LTE.
Therefore, neither 1 nor 2 is correct.
