FMC-flavoured BlackBerry on the way

RIM is developing its first dual-mode BlackBerry, the company's co-chief executive has revealed.

According to reports, Jim Balsillie told delegates at the JPMorgan Technology Conference in Boston the company has come around to the idea of including both wi-fi and cellular functionality in its devices - something many of its competitors have been doing for years.

Such technology is central to what is known as fixed-mobile convergence (FMC), which describes the concept of being able to contact someone's desk phone or mobile phone through a single number, and those two phones sharing PBX functionality.

Balsillie is quoted as saying that, although he was not a fan of wi-fi functionality while it was being "hyped as something that would… get rid of your cell phone", he has now decided it is a satisfactory complimentary technology to cellular.

Referring to wi-fi in BlackBerry smart phones as an imminent proposition, he also suggested such an inclusion could take place as soon as "the latter half of this year", as long as the issue of hand-off - the seamless transitioning of a call from a cellular network to a wireless VoIP service, or vice versa - was sufficiently resolved.

Balsillie also claimed most operators are supportive of FMC, as it results in more calls made through a PBX being routed to a user's mobile phone, whereas they might previously have gone to the voicemail attached to a fixed-line phone.

Earlier this month, RIM announced it would make it possible to use a BlackBerry as an extension of a company's PBX system through the introduction of its Mobile Voice System.
