New technology from Nokia Siemens could provide more 3G data bandwidth

Nokia Siemens Networks has recently presented a technology that would probably lessen data crunch at certain carriers. DFCA (Dynamic Frequency and Channel Allocation) operates a reduction of the needed amount of bandwidth a GSM call requires in order to work. This approach results either in doubling the space for the conventional type of voice calls or in leaving more room to be used by cellular data which include 3G over HSPA and 4G on LTE. Furthermore, it can reduce the need of having extra cell sites and can improve the quality of the services on existing areas of the network.

The infrastructure builder of the network has not named customers yet for DFCA but has outlined that software, more than hardware, would achieve much of the necessary work.

The implementation of the DFCA could be helpful in alleviating the congestion due to the ever growing number of smartphones, which triggered slowdowns in the United States on AT&T’s network, but was also supposed to cause problems on O2 in the United Kingdom, SoftBank in Japan as well as in other networks including large numbers of users owning Android devices and iPhones. In many cases, voice is overtaken by data and here is where DFCA or equivalents intervene by re-prioritizing networks without needing to add equipment immediately.

AT&T and other carriers do not use Nokia Siemens hardware for their networks and therefore would not perceive uniform benefits without having to change hardware.
