Among the many smartphones being introduced to the public at IFA 2011 are three additions to Samsung's Wave family - namely the Wave 3, Wave M and Wave Y. All three phones use the company's new bada 2.0 platform, which according to Samsung "brings together a wide variety of new capabilities including multi-tasking, Wi-Fi Direct, voice recognition and Near Field Communication (optional)." The platform is also said to allow for photo and file sharing without internet networking, mobile payments and transport pass-card recharge.

The leader of the pack, the anodized aluminum unibodied Wave 3, features a 4-inch Super AMOLED display, a 1.4GHz processor and HSPA+ connectivity. Apps include Samsung's Social Hub, ChatON and Music Hub, which enables users to purchase and download music tracks and albums over-the-air. It also has 3 GB of internal memory (expandable to 32 GB), front and rear cameras (the rear is 5 MP), and offers up to 480 hours of talk time on one charge.

In the middle is the Wave M, with a slightly smaller 3.65-inch tempered glass HVGA screen, a 832MHz processor, and HSDPA 7.2 connectivity. Most of the other specs are similar to the Wave 3's, although it has 150 MB of memory, and the phone itself is a bit smaller and lighter, with a less powerful battery.

Finally, there's the Wave Y, which is the smallest in terms of overall size, weight and battery power. It has a 3.2-inch HVGA display and a single 2 MP camera, with most of the other specs matching up with the Wave M.

Below is a chart illustrating how the main specs of all three devices compare.
