Nokia Siemens Networks today detailed a technology which potentially could help with the data crunch casuse by smartphones. Dynamic Frequency and Channel Allocation (DFCA) reduces the amount of bandwidth that a GSM call needs to work. The approach can either double the room for conventional voice calls or leave more room for cellular data, including 3G over HSPA or 4G on LTE.
The network infrastructure builder hasn’t named customers for DFCA but has emphasized that software, rather than hardware, does much of the work.
