Skype has veen available for Mac users for a long time now. It has recently reworked it video quality for higher definition pictures at 25 frames per second. However, it still offers 1-to-1 video calls only, which is finally not really conferencing. ooVoo is one alternative, and one of the most prominent players in the video conferencing industry. 1-to-1 video calls are free with ooVoo, but users can make calls to up to 6 persons for $18 a month, and to 3 persons for $8. ooVoo has its HD version for Mac, and is therefore in direct competition with Mac's in-house iCall. But ooVoo is better entertained and goes round problems more smoothly, although it is a little heavy on resources. They are now working on a Linux version.

When we talk about Wi-Fi, apart from talking about wireless Internet, we also talk about how it is limited to a cafe or station, in a radius of only dozens of feet. Novatel has made a breakthrough towards Wi-Fi location independence - because finally, anything wireless should ultimately be free from location dependencies.

MiFi is a slim and ultra portable device that generates a Wi-Fi hotspot within a radius of 30 feet, allowing up to 5 devices to connect. The most interesting thing about the MiFi is that it can be carried in the pocket or bag and can therefore give Wi-Fi connectivity anywhere there is cellular 3G coverage, be it in a car, train, plane, the beach or the forest.

Skype makes the news again this week - it has released its full-fledged Windows Mobile phone software (downloadable from this link), which was in beta so far. Also, Apple approved Skype 1.1 for the iPhone and iPod. But Skype isn't just making people happy; it is causing disappointment too.

Since I reported on Skype and Blackberry some time back, observing that contrary to what was announced by Skype, no Skype client has been released for BlackBerry, I kept receiving comments from disappointed BlackBerry users, most of whom have been expecting Skype for BlackBerry since a long time. Alex commented today, "I think this is rubbish. Yes, there was a call for beta testers on the skype lite forum for Bold owners. However, that was all, and the suggested release date passed by, and NO update at all." I suggest patience, wishing that a reaction comes from inside Skype itself. Meanwhile, Blackberry users can benefit from the advantages of VoIP through other services like Vopium, Truphone, Yeigo, Raketu etc. Find a list of those applications there.

Blackberry is the most popular smartphone for enterprises. Yet, it has been lagging behind in terms of VoIP implementation. This is mainly due to a lack of adequate solutions and applications for RIM's machines. Blackberry is nowadays knowing unprecedented popularity, and many VoIP providers are including it into their supported handset lists.

Agito, an enterprise communication solutions provider, aims at capitalizing on Blackberry's position on the enterprise market. Up to now, enterprises using Blackberry have had to content themselves with incomplete and often expensive solutions. Agito now provides a Blackberry solution that includes PBX functionalities in its RoamAnywhere router and an intelligent VoIP application for Blackberry handsets. This way, calls are shifted from cellular to Wi-Fi, thereby saving a lot on business communication. Other benefits include enhanced mobile PBX capabilities, with some PBX functionality present on Blackberry handsets, unified communications benefits, low investment on hardware, among others.
