![]() I have confirmed this myself (but we do not use CATV as our TV since we get all we need from internet streams). I was thinking that perhaps my problem was signal strength? I have just moved in to this house, so I do not know exactly how the cables are drawn and how much/which cable we are talking about, however the previous owners had to install an amplifier for the CATV signal at point A in order to get a proper signal at point C and onwards. Now, in practice, our house consist of 10+ CATV outlets, where at least two outlets are between A and B, and B and C, and there are also outlets after C in the cable layup (which also do not work from A). I have tried so much, thinking that perhaps the CATV signal was causing issues, and have used different splitters, filters at all possible places ++ Likewise, I have tested that B to C are working on its own, with peer-to-peer pinging. When A to B are connected and working flawlessly, and I plug in point C, after a while the network shifts from B to C, and since A has the internet/DHCP service, I basically end up with a faulty net everywhere. I am able to get MoCA working from A to B, and from B to C, however, A to C does not work. GoCoax MoCA adapter A -> GoCoaX official splitter (all frequencies) -> wall/cable -> GoCoax MoCA adapter B -> wall/cable -> GoCoax MoCA adapter C. The most simple schematic I can configure here is: To spare you from my hours of troubleshooting, I have narrowed my problem into a simplified case Ī is my office in the ground floor, where my router is, fiber, CATV++ comes in to the house. I have a rather big house with 10+ coax outlets, and have 5 GoCoax MoCA adapters that I have tried to get working for some time. Ethernet will always be faster those instances where you are uploading and downloading data at the same time, but MoCA gets pretty close.I am reaching out to this forum and topic as it seems like both the and fellow users/experts is around. The medium access control (MAC) layer for MoCA uses a distributed mesh network architecture with time division multiple access (TDMA) for scheduled access, just like cell phone technology.Īlthough it is half-duplex, MoCA can provide near-equivalent speeds to Ethernet. MoCA uses the same technology that cell phone carriers use to send/receive data, using orthogonal frequency division modulation (OFDM) subcarriers that are adaptive-modulated by various modulation schemes. Because coax has only one line, it can never do full duplex however, using MoCA technology, you can send and receive data near-simultaneously over a single data line. Ethernet cable can do full duplex because it can send transmit and receive data simultaneously using different lines. ![]() I attached our report for your reference.Ĭlick to expand.Coaxial cable has an inner and outer core that share a geometric axis, compared to Ethernet cable which has 8 separate lines for data transmission. If you can test the MoCA 2.5 adapters with professional test equipment, you can find with packet size over 1280 bytes, you can get more 3Gbps bandwidth. Don't worry, for most Internet service, such as web suffering, watching video and gaming, we are using large packets only.Ĥ, In fact, MoCA 2.5 can achieve about 3Gbps bandwidth. The longer packet size, the higher bandwidth. the small packets get a much lower bandwidth, for example, 64Bytes packet only get about 250Mbps. Only large packets the length is more than 1000Bytes can get 2.5Gbps. if A to B is using 1Gbps bandwidth, then C to D only can use 1.5Gbps bandwidth.ģ, Not all the packet length can get 2.5Gbps For example, there are 4 nodes in the same network, suppose all them have 2.5GbE port. The bandwidth is allocated by TDM mode.Ģ, MoCA bandwidth is shared by all the MoCA devices in the same network.Īll the MoCA devices are connected to the same coaxial network, so they share the total MoCA bandwidth, about 2.5Gbps for MoCA 2.5. If one node talks to another one node, the others must wait. Today let me do more introduction about the MoCA bandwidth, and try to find out can we benefit from 2.5GbE Ethernet port.īecause coaxial cable only has one circuit, so MoCA is not a full-duplex system. Perhaps it is because MoCA2.5 emphasizes that it can support 2.5Gbps bandwidth. ![]() ![]() We found many people asking for the MoCA 2.5 adapter with 2.5Gbps Ethernet port.
