Busy hour congestion is the leading contributory factor in outages with 37 percent saying occurring often, 52 percent as rarely and 11 percent as never, according to a survey by Heavy Reading.
Network congestion and overload is the most common cause of network outages and degradation, with 81 percent of respondents listing it, followed by network failures at 46 percent.
Network failures are the cause of the most severe outages and degradations – named by 85 percent of respondents, according to analysis firm Heavy Reading that conducted the survey of 54 global mobile operators for Spirent.
There is an increase in the number of outages. Mobile operators are taking 48 hours or more to fix such issues.
The launch of a new phone is typically less disruptive than the launch of a new service, with 44 percent stating a new phone is never a contributing factor compared to 28 percent marking never for the launch of a new service.
“Among the most notable findings in this year’s study is that network failures are now the leading cause of mobile network outages, where physical link failures were the primary cause a couple of years ago,” said Patrick Donegan, senior analyst with Heavy Reading.
