IPhone best for calls, says report


The iPhone 3G (2.2) is the best performer for call reliability out of six smartphones, according to a new report, All Phones Are Not Created Equal, by Andorra-based Mobile Test Labs.

The six smartphones were tested in static, walking and in transit modes for: call setup; call maintain; call maintain during soft handover; and call maintain during IRAT (inter-radio access technology) handover.

The six smartphones featured in the test were: Blackberry Bold 9000; Blackberry Storm; Apple iPhone 3G (then with v2.2 firmware); Apple iPhone 3G (with the v.2.0 launch firmware); Nokia E71; Samsung SGH-F480 Tocco; and the Sony Ericsson C905.

The tests found that performance varied enormously and none of the handsets were good at everything.

Two general observations could be made: a handset that was bad at adding a radio link, usually performed poorly in the handover test where it tried to add a new radio link; and handsets that had problems maintaining a radio link, usually dropped a call easily in a handover scenario, where it was subject to interference from a second call.

The report also found that the sheer amount of features now expected to appear on a smartphones could compromise overall performance of the phone. The phones are running out of room and processing power, which does not bode well for performance, not only for call reliability, but also for data and video applications.

The Samsung recorded some excellent results, but struggled in the single-cell call set up and maintenance areas. The SE C905 was a largely consistent performer, but had some weak areas. The Nokia performed well in setup, but less well in some of the call maintenance tests. The two RIM handsets performed very differently with the Bold performing much better than the Storm.

But none performed perfectly, which indicates that there are big improvement opportunities to be made by handset manufacturers.
