CNET editors took the Nexus S 4G out for a spin and discovered that it does have poor WiMax performance compared with other Sprint 4G devices.
The
Last weekend, I took the Nexus S 4G out to Golden Gate Park in San Francisco, and the 4G coverage was dismal to nonexistent. I used Ookla.net's Speedtest app to measure speeds. The best I could get was 3.36Mbps down and 1.08Mbps up, with an average of 2.25Mbps down and 0.8Mbps up. As I traveled across the city, signal coverage didn't seem to improve beyond a couple of bars. However, I wasn't sure if this was a failing of Sprint's 4G coverage, or of the Nexus S 4G in particular.
So, over the long Fourth of July weekend, we compared the Nexus S 4G with the
For measurement, we ran the Speedtest app on both phones 10 times each to get average download and upload speeds for each location. We also timed how long it would take to load the CNET front door, and we timed how long it would take to upload a 37.2KB camera-phone photo to a limited Google+ circle (just so we don't flood our followers with the same photo over and over again).

What we discovered was that in areas of heavy congestion/poor reception and nonexistent 4G coverage, the speed test results were about the same. In fact, the Nexus S 4G was a tad faster at times, even when the HTC Evo 3D showed more bars. However, in an area where we usually get strong 4G signals, the Nexus S 4G lost consistently to the Evo 3D.
This shows that if you take 4G out of the equation, the two phones have about the same speeds. However, in a good 4G area, the Nexus S 4G failed to keep up with the HTC Evo. As a result, we do think there's something not quite right with the Nexus S 4G's WiMax coverage. We've heard that Sprint and Google are already working on an update; we'll let you know once we find out if and when that happens.
UPDATE: Sprint has announced that it will be rolling out an update to the Nexus S 4G that will hopefully resolve the signal strength issues.
