The number of fixed broadband connections grew by 13 percent last year, compared to 2008, says ABI Research.

According to the research firm, there were 430.7 million fixed broadband subscribers in 2009 and by 2015, this will hit 548 million.

"Fixed broadband is an attractive platform for the delivery of IPTV, gaming services with low latency and rapid access to web content," says Jake Saunders from ABI Research.

ABI says 65 percent of these connections are DSL, while 24 percent are fibre and cable makes up the remaining 11 percent cable.

Japan and South Korea have the greatest number of fibre subscribers, at 55 percent and 49 percent respectively.

ABI Research also forecasts that number of fibre broadband subscribers worldwide will hit 134 million by 2015.
