Explanation:
The correct answer is Neither 1 nor 2. LTE or Long Term Evolution is a series of 4G network standards that were agreed in 2008. Hence Statement 1 is Not Correct. LTE improved on the radio technology of 3G’s WCDMA and introduced OFDM or Orthogonal Frequency-Division Multiplexing. ITU (The International Telecommunication Union) recognises the lack of clarity in the term 4G and has determined LTE - Advanced and WirelessMAN-Advanced or WiMax 2 as “True” 4G. VoLTE is a technology update to the LTE protocol used by mobile phone networks. Under LTE, the infrastructure of telecom players only allows transmission of data while voice calls are routed to their older 2G or 3G networks. VoLTE is both data and voice technology. Hence Statement 2 is also Not Correct. Basically VoLTE systems convert voice into the data stream, which is then transmitted using the data connection.
