Verizon today expanded on some of the actual results for its expected 4G network. After testing in the Boston and Seattle areas, the provider estimates that a real connection on a populated network should average between 5Mbps to 12Mbps in download rates and between 2Mbps to 5Mbps for uploads. Actual, achievable peak speeds in these areas float between 40-50Mbps downstream and 20-25Mbps upstream.
