Analyst says 2G & 3G can be switched off by operators by 2020

According to research, the 2G and 3G network service provided by mobile phone service providers would be switched off in 5 year’s time. Ovum, the leading advisory and global tech research firm has, according to their research, found mobile phone service providers to be moving over from 2G and 3G networks of today, with the 3G being switched off first, by around 2020.

Principle analyst at Ovum, Nicole McCormick, however said the majority of operators aren’t in a position today to close down their legacy networks, nor in the next 1 to 2 years. The research pointed out that mobile network providers will consider the revenue generated by their 2G and 3G networks, including from voice calls and roaming. The Ovum’s principal analyst was sure that they don’t expect operators to retire their legacy networks en masse until nearer to 2020. The analyst also explained that as 2G still remains as an important source of revenue, 3G may be switched off before 2G.

The Brisbane-based analyst said LTE (Long Term Evolution) or 4G provides better than 3G the mobile broadband experience and with VoLTE (Voice over Long Term Evolution), LTE can handle the task of carrying on the voice function of 3G and this shows the possibility of operators opting to switch off 3G networks before they close 2G. Before the introduction of of VoLTE, voice responsibilities were exclusively of the 2G networks, with data being sent and received on 3G or 4G.Reports of Vodafone and Three introducing VoLTE technology to enable the making of calls using 4th generation technology by consumers, suggest the move from 2G and 3G legacy to 4G only networks.
