A survey by analysts Frost & Sullivan has revealed that the already popular wireless e-mail is set to become even bigger – but it’s a fieldthat’s experiencing teething troubles. Wireless e-mail is already a major factor in mobile enterprise, and new customers are coming on board every day. "Mobile connectivitynot only improves flexibility, but also allows faster decision making and increases efficiency by utilising otherwise wasted time, for example when traveling. Overall, it improves the effectivenessof the user to the business," explained Shomik Banerjee, industry analyst at Frost and Sullivan. In Europe, most operators have their own e-mail services, but they also have a third-partywireless e-mail platform for people like Microsoft. BlackBerry, made by RIM, has its BlackBerry Internet Service,letting subscribers connect to their personal e-mail accounts. The biggest problem is that there’s currently very little interoperability between all these services, and bringing thatinto line is going to make a huge difference for the future of wireless e-mail. RIM has made an attempt with its end-to-end service, while Microsoft wants its ActiveSync to be dominant in themarketplace. So far others efforts, such as middleware, have failed to provide a solution.
