david 810 Posted January 31, 2020 Author Share Posted January 31, 2020 (edited) On the wireless front, I did some testing late last night. The laptop used is a Windows 7 laptop with an internal 802.11n adapter I have an 802.11ac adapter, but haven't installed it yet. The router/wireless access point is an ASUS tri-band router, with a 2.4 Ghz radio and two 5.8 Ghz radios. For file transfers, I was running a WebDAV server on the Pro1 and mapping that as a drive letter in Windows Explorer. This approach would only let me send data to the Pro1, not from the Pro1 to the laptop. I'm guessing that is due to the lousy WebDAV client built into Windows. I'll try with a better client some other time, as well as trying FTP. NOTE: This file transfer was timed with a stop watch and then the rate calculated manually. Highly prone to error, so the speeds should be taken as approximate. Laptop reports 300 Mbps link speed (802.11n), Pro1 reports 866 Mbps link speed (802.11ac). About 9 feet from the wireless access point. The first 5.8GHz radio in the router has some interference from another system in the house, so it might not be transferring at maximum speed. Sending file from laptop to Pro1 internal storage: Pro1 and laptop on 2.4 GHz = 38 Mbps Pro1 2.4, laptop 5.8-2 = 60-70 Mbps Pro1 and laptop 5.8-2 = 76 Mbps Pro1 5.8-2, laptop 5.8-1 = 126 Mbps Pro1 5.8-2, laptop gigabit ethernet to wireless access point = 220 Mbps. Full duplex matters. Testing raw data speeds with WiFi Speed Test (https://play.google.com/store/apps/details?id=com.pzolee.android.localwifispeedtester&hl=en_US) between the Pro1 and a Pixel 1 phone. NOTE: The tests can be fairly variable. I didn't run N tests and average the results. I just ran one or two (or more if they didn't come close) and reported the approximate values for semi-matching tests. Pro1 as server: Pro1 5.8-2, Pixel 1 5.8-2 = about 100 Mbps Pixel 1 to Pro1, about 200 Mbps Pro1 to Pixel 1 Pro1 5.8-2, Pixel 1 5.8-1 = about 150 Mbps Pixel 1 to Pro1, about 400 Mbps Pro1 to Pixel 1 Pro1 as client: Same speeds as above. So Pro1 can send much faster to the Pixel 1 than it can receive, for some reason. Either the Pro1 sends faster than it receives, or the Pixel 1 receives faster than it sends, or there is some other variable at play here. Once I upgrade my laptop with the 802.11ac adapter, I'll test to/from it as well, with WiFi Speed Test (there is a windows server program). UPDATE: I tested from a Pixel 4 XL just now and it also shows the Pro1 sending much faster than receiving. Pro1 5.8-1, Pixel 4 XL 5.8-2 = about 300 Mbps Pixel 4 XL to Pro1, about 540 Mbps Pro1 to Pixel 4 XL Pro1 5.8-1, Pixel 1 5.8-2 = about 140 Mbps Pixel 1 to Pro1, about 475 Mbps Pro1 to Pixel 1 (retesting from last night to check consistency) Pixel 1 5.8-1, Pixel 4 5.8-2 = about 310 Mbps Pixel 4 to Pixel 1, about 150 Mbps Pixel 1 to Pixel 4 NOTE: Before these tests, the Pixel 1 and Pro1 weren't getting close to the speeds they were last night. I rebooted the ASUS router and the speeds went back to where they were yesterday, or even a bit faster. Must have been something built in up the router. I'll have to schedule it to reboot periodically I guess. Also, I am holding the Pro1 about 2-3 feet away from the Pixels and they are sitting on a flat surface. Having them too close together affects the speeds. NOTE: The Pixel 1 and the Pixel 4 XL both have 2x2 MU-MIMO, as does the Pro1. However, obviously, either something in software or hardware of the Pixel 4 allows for significantly faster speeds. It might be simply a matter of processing power a those speeds. The Pixel 4 does support 802.11ad, but my router doesn't support that. What to make of the Pixel 1 to Pixel 4 test? Pixel 4 to Pixel 1 sends faster than Pixel 1 to Pixel 4. About twice as fast. And it is about the same speed as Pixel 4 sending to the Pro1. So maybe that is as fast as the Pixel 4 can send. The Pro1 can send to either Pixel significantly faster than the Pixel 4 can send to the other phones. The Pixel 1 to Pixel 4 and Pixel 1 to Pro1 are about the same. So that might represent as fast as the Pixel 1 can send. Possible conclusion: In other words, the Pro1 can't receive more than 140-150 Mbps out of the Pixel 1. That is probably as fast as the Pixel 1 can send. The Pro1 can't receive more than 300-310 Mbps out of the Pixel 4. That's probably as fast as the Pixel 4 can send. For anyone with Gigabit Internet and an 802.11ac router with multiple antennas, you can possible test what the max receive speed could be for the Pro1. I can't test it, because the devices I have for testing aren't fast enough for sending to the Pro1. Your upload speed will probably be slower than a LAN to LAN WiFi test, but it is the max speed the Pro1 can receive at, over WiFi, that we are trying to determine here. Additional test done: I did speed tests with the Pro1 on WiFi and the laptop plugged into the router with Gigabit Ethernet. Instead of doing file transfers like the first test, I used an iperf3 application on the laptop (from http://iperf.fr) and one on the Pro1 (Magic iPerf3). The applications can act as clients or servers, just like WiFi Speed Test. I could send to the Pro1 about 300-310 Mbps. That was about the same as the Pixel 4 could send. However, I could only send to the laptop from the Pro1 at about 240 Mbps, far slower than the Pro1 can send to either of the Pixels. That does somewhat match the speed I could transfer a file to the Pro1 from the laptop with the same setup (ethernet for laptop and wifi for the Pro1). It is possible the laptop can't send faster than that, which is a bit surprising. The laptop sends far faster than that over USB 3 to the Pro1, and that is with the Pro1 writing to internal storage. But maybe the ethernet hardware in the laptop isn't up to the task. Edited January 31, 2020 by david 1 Quote Link to post Share on other sites
