![]() The issue of frequency overlap and conflict between the DOCSIS upper frequency range and MoCA low frequency is a known issue. ![]() At the present time, anyone considering a MoCA installation should be aware of the upcoming changes. So, its possible that you might see several years of use out of any MoCA equipment before any problems arise due to Rogers changing the downstream and/or upstream frequencies. How fast Rogers will change its frequency configuration is anyone's guess. These changes are in line with the extended DOCSIS frequency ranges which will provide increased data throughput on the downstream and upstream side. That upper 1218 Mhz frequency overlaps the lower D-band MoCA frequency. ![]() The downstream frequencies may change from 200 to 1002 Mhz to 200 to 1218 Mhz. From what I've read, and I have no idea as to whether or not its factual, Rogers may be looking at extending the upstream frequencies to run using the high split configuration which runs from 5 to 200 Mhz. MoCA filters and MoCA adapters are built, for the most part to use the 5 to 42 Mhz range for upstream data out of the modem and 200 to 1002 Mhz for downstream data to the modem. future data rate upgrades are something to consider. So, if you ever changed the modem for an XB7, that modem has a 2.5 Gb/s ethernet port on it. That port typically supports 1 Gb/s and 2.5 Gb/s connection rates, and probably 10 and 100 Mb/s but don't quote me on that one. Note that there are MoCA adapters around that have 2.5 Gb/s ethernet ports. You would also have to replace any existing splitter with a MoCA 2.0/2.5 qualified splitter, where that MoCA splitter has internet port to port frequency specs which supports MoCA 2.5 ops. But, you have to enter that code into all of the adapters. Note that adapters usually have a security code that you can enter to encrypt the MoCA data so that if it did manage to migrate outside of your home it should be unreadable by anyone else. That prevents external MoCA data from entering and impacting your MoCA system and prevents your MoCA data from impacting on someone else's MoCA network. You will also need a MoCA Point of Entry filter connected to the incoming cable. Is it still set for D-High, or does it use the Extended D band now? MoCA 2.5 you comment on the current MoCA configuration for the 4582 modem. Have a look at pages 9 and 13 for the MoCA frequency ranges which shows D-Low, D-High and the Extended D band which is the band that you want to use for maxiumum data rates thru the MoCA adapters: Here's a reference link to the MoCA 2.5 spec. That would give you the maximum data throughput via the MoCA adapters. In this case you would simply be better off buying two adapters which would allow you to use the entire D band for MoCA ops. If it still is the case, and you don't have two or more Nextboxes running in the Whole Home network mode, that would mean that the 4582 is locked into using D-High which limits the MoCA network throughput. I don't know if that is still true these days. ![]() The 4582 MoCA channels were locked to D-High so that the Nextbox Whole Home network could use D-Low. Even if you had one available to you for some reason, you wouldn't be able to register it for service on your account, so that discounts that possibility as well. An interesting idea but that won't work as Rogers will only allow one modem on an account, so, you wouldn't be able to run another 4582 or any other modem.
