More people are set to make use of emailing while on the move over the next few years as business users tap into wireless internet connections.

Revenues for firms offering wireless connectivity are predicted to enjoy a boost from this year's total of £1.3 billion to £4.7 billion in 2012, according to research firm Frost & Sullivan.

The company's industry analyst Shomik Banerjee said: "The business case justifying the benefits of mobile connectivity is well understood and appreciated."

He added that the main attractions of mobile email services are increased flexibility, quicker decision making and the saving of travelling time – while it could also be used to ensure business continuity in the event of a disaster.

"Overall, it improves the effectiveness of the user to the business," Mr Banerjee explained.

He cautioned, however, that this growth may be hindered by mobile industry decisions to not always make their devices compatible with the most widely used technologies, such as P-IMAP developed by the Internet Engineering Task Force.
