Mobile data users who are planning to switch to Reliance Jio 4G services have something to cheer about, as a latest report states that the download speed on the network touched a peak of 70 megabit per second (mbps) during the trial phase, but stayed in the range of 15-30 mbps most of the time.

The download speed of Reliance Jio 4G services was "impressive but it is still an empty network," said a global brokerage firm, which conducted a trial study on the beta phase of 4G network rolled out by telecom arm of Mukesh Ambani-led Reliance Industries.

"We experienced peak download speed of 70 Mbps during our trials, and on most occasions in the 15-30 Mbps range, even on the move," said Research Analysts Sunil Tirumalai and Chunky Shah at Credit Suisse in a report.

At a peak download speed of 70 mbps, a user can download a Bollywood movie-size video in just 30 seconds, while the same can be downloaded in three minutes at 15-30 mbps speed.

The report has also found Reliance Jio's coverage in urban areas remaining at par with existing players, but noticed the coverage as "poor" in rural areas.

Measuring the difference between the commercially launched 4G services of India's largest telecom operator Bharti Airtel with beta network of Reliance Jio, the firm found the former's services as "slower" on many occasions compared to that of the latter's.

"Airtel 4G giving 10-20 Mbps, often slower than Jio, and 3G network speeds of sub 2Mbps (peak 7 Mbps)," The Financial Express quoted the Credit Suisse report as saying.

While conducting trials, the analysts also did not experience any call drop issues on Reliance Jio network in Mumbai but faced losing signal 3-4 times upon entering village roads.

"Overall, our take away is that the Rjio network is turning out to be as strong a threat to incumbents as we had feared. Next focus would be on pricing and marketing execution," the report said.

However, Credit Suisse analysts noted that the download speed on the Reliance Jio 4G network will drop after its commercial launch due to increased number of users.
