Informa Telecoms and Media has said that it is not "economically viable" for UK wireless carriers to deploy LTE 4G technology on their networks before 2015.
According to research conducted by the company, the existing HSPA 3G network will be able to manage current and future mobile traffic demands in the mid-term.
The research firm said that traffic congestion will only start to appear by 2013, and then only in certain hotspots.
Dimitris Mavrakis, a senior analyst for Informa Telecoms & Media, said in a statement: “UK mobile broadband operators are faced with fierce competition while margins from voice are shrinking.”
“Even though there is growing demand for mobile data by smartphones and USB modems, current UK mobile network deployments are so dense that it would make the introduction of LTE both an investment heavy and somewhat unjustifiable decision,” he said.
LTE 4G technology will offer a maximum mobile download speed of 100 Mbps. On an average, users will be able to get an average download speed of 50 Mbps.
Currently, the existing HSPA 3G technology offers a maximum speed of 14 Mbps, while 1 Mbps is average.
