Possible Nexus 5 (LG-D820) passes Wi-Fi certification with gigabit support
The evidence has mostly pointed towards LG model D820, and likely D821 as well, as being what we are generally calling the Nexus 5. There was a bit of skepticism on that front for a short time, but overall the consensus says that those models are the next Nexus handsets. We've seen those models pass through the FCC, and now two different models of the D820 have passed Wi-Fi certification.
The two models listed are the LG-D820_S and LG-D820_C. Unfortunately, it is impossible to tell the difference between the two models based on these certification results. The D820 is likely the GSM model, whereas the D821 is the CDMA variant; so, it could be that the D820_S and D820_C differ slightly in supported GSM bands or LTE bands. We can't say for sure.
However, that doesn't mean this certification filing brings no good news. The certification does confirm that the devices support 802.11ac, which means theoretical gigabit speeds. It would also make this the first Nexus device to support the new Wi-Fi standard.
