Mobile Internet speeds in Seoul are the fastest among seven cities in the world, a survey by a US mobile analytics firm showed on Tuesday.

In Seoul, a median download speed for the wireless network run by mobile carrier LG Uplus is 74.7 Mbps, followed by Madrid with 44.6 Mbps and Tokyo with 39 Mbps, according to the survey by RootMetrics.

London came fourth with 29.8 Mbps, followed by Paris with 29.7 Mbps, Dublin with 28.7 Mbps and New York with 23.7 Mbps.

The download speed by LG Uplus means that it takes about 1 minute for a user to download a song via smartphone.

Scott Brady, chief revenue officer at RootMetrics, told reporters that mobile network performance in Seoul is one of the fastest in the world.

The other two mobile carriers in Seoul -- SK Telecom and KT -- also received top grades for their mobile network performances, according to the survey.  (Yonhap)
