If you've ever been in the middle of responding to an email on a smartphone and found yourself cut off because you went indoors, Motorola has a solution. The company's AXPT access point, to be sold to businesses by cell carriers, is an access point designed to expand the reach of 3G networks inside buildings. The AXPT works with UMTS and HSDPA networks, and is designed to allow users to stay on one network when using a 3G-enabled device such as a laptop, whether they're inside or outdoors, rather than, say, having to switch from a 3G network to WiFi. Moto will demonstrate the AXPT at 3GSM in Barcelona next month. Pricing has not been announced.
