Hi Jeroen Interesting topic!
Swisscom deployed 'FTTS' at my home last year, promising 'at least 500 mbit/s with g.fast' for every household, causing the municipal administration to reject plans for proper FTTH from competitors, this as a sidenote. Actual situation: I live about 250m away form the DSLAM in the street. After several cases opened @ Swisscom, they found out it is just about a little too far away for g.fast to work properly. In this 'at the limit' situation I tested two ZyXEL XMG3927-B50A (to make sure I had not a broken one) in bridge mode (PPPoE on Mikrotik). Tested directly at the HÜP. Results: * g.fast is slower than VDSL2 at this distance in both up and down speed (way slower than what Swisscom announced). * XMG3927 shows very strange packet delays. There is no packetloss, but latency sometimes jumps to about 500ms or more, for single packets (usually small packets like tcp syn) causing re-transmits, without apparent reason. This happens in g.fast AND VDSL2 mode. Also happening if ethernet interface is set to 100Mbit/Fduples. Opened Case @Studerus, They never heard of that issue. * Older VDSL2 only Modem: VMG1312-B10A odes not show this lately issue (so I kept that modem) I know, that the XMG3927 has wider filters (up to 500Mhz or so) to allow g.fast. I know there are a couple of low power 430MHz transmitters in my neighbourhood. Could they be the cause of that issue? Looking forward of other's experiences with g.fast bridges. -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________ _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
