AT&T Details Network Improvements But No Further Expansion Plans

Following AT&T’s recent decision to allow VoIP applications on the iPhone, I questioned whether or not the carrier’s network could handle the increased traffic. Yesterday, AT&T addressed some of the issues I raised as it announced third-quarter earnings. The carrier reported that dropped calls are down 12%, while instances of calls failing to connect are down 30%. Absent from the announcement, however, were any new plans to expand its data network, though the carrier did concede that it has seen an “explosion” in customers’ data usage.
