As our design team noted last week, the Nokia Lumia 925 is our first Lumia smartphone to use metal as a part of its exterior make-up.

This looks gorgeous, and adds robustness to the phone. But what’s worth noting is that it does not impact on the strength of the signal you’ll be able to receive on the phone.

On the Lumia 925, the aluminium ring around the phone actually act as parts of the phone’s radio antenna system. The main antenna is located in the bottom area of the phone and two more towards the top of the phone. There are then stripes that separate the antennas from the other parts of the metal ring.

Nokia-specific technology incorporated within the antenna solution maximises its use of radio bands – whether you’re on GSM, WCDMA or LTE networks. It will also adjust the ‘balance of power’ between the antennas according to how you’re holding your phone.

The end result is that you’ll get equally good radio performance out of the Lumia 925 as you would from a wholly polycarbonate phone, plus the most important benefit in the form of a stunning design.

Of course, if you deliberately use two hands to cover every edge of the phone, you’ll manage to reduce the signal. But that’s true of any other phone, too. You may also find it a little tricky to operate the buttons that way!

So relax, and enjoy Nokia Lumia 925 and its sleek design, any way you like.
