Nokia Siemens Networks today detailed a technology that could potentially help mitigate the data crunch at some cellphone carriers. 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. Either can reduce the need for extra cell sites or improve the quality on existing parts of the network.
