![]() The Multimedia Over Coax Alliance (MOCA) market has witnessed remarkable growth in regions such as North America (NA), Asia Pacific (APAC), Europe, USA, and China. Additionally, MoCA can improve Wi-Fi coverage and performance by delivering data over coaxial cables, reducing interference and improving reliability. Satellite communication companies can utilize MoCA to facilitate efficient data transmission between satellite receivers and home networks. Cable TV providers can use MoCA to deliver high-quality video content to subscribers, while Telco/IPTV operators can enhance their offerings by delivering high-speed Internet and TV services over existing coaxial infrastructure. When it comes to market applications, MoCA technology finds use in Cable TV, Telco/IPTV, Satellite Communication, and Wi-Fi markets. MoCA supports data rates of up to 270 Mbps, while MoCA and offer higher speeds of 800 Mbps and Gbps, respectively. MoCA, MoCA, and MoCA are different versions of this standard, with each offering improved performance and features. The physical media can support up to 110Mbps (MOCA 1.0), 140Mbps (MOCA 1.1) or 450Mbps (MOCA 2.0) user throughput per channel (up to 5 channels in MOCA 2.5), but that's shared bandwidth (all traffic summed together).The Multimedia Over Coax Alliance (MoCA) is a technology standard that enables high-speed data transfer over existing coaxial cables. Under ideal conditions, it is possible to get 100Mbps UDP throughput on a pair of MoCA nodes (1518 byte packets). Round- trip ping times should go up by roughly 4.5ms. Times are averages, as the exact time depends on the alignment of the time of arrival to the scheduling period). ![]() The reservation timeslots and mail packets are on a fixed schedule (approximately- there are cases where the timing changes if you have a poor link) with a consequence of an unloaded MOCA network having a transit time of ~2ms going from the master node, or ~2.5ms going anywhere else (master node transmit is faster since it gets to skip the reservation step. The 4ms of latency is a product of the MOCA protocol.Īs a fully scheduled network, each packet must wait for a timeslot to send a reservation packet, wait for the schedule to be updated (map packet), and then wait for the actual scheduled time. MoCA was never meant to be all things to all people though, and while I personally use MoCA in my home I never got my own parents to use it - they just have the one computer hooked directly to their router, and WiFi for their iPad. MoCA was a very targeted solution for adding IP connectivity to things which were already wired together on a Coax network, and it did a great job at that. then decided that lack of demand meant it's not worth developing/advertising new/improved versions of the products, etc. In turn, this means most people have no idea that MoCA even exists, so they don't go looking for it. The consumer market for bare Ethernet-Coax gateways was smaller (see above) as it has to compete with both WiFi and "just run some new CAT-5" (as well as niche things like HPNA/G.hn) so it didn't get a lot of focus or advertising. The market for bare Ethernet-Coax Bridges (ECB) was always tiny in comparison. They could also pre-configure the MoCA so it wouldn't interfere with some other stuff they might want to put on the cable (Example: DirecTV put its downlink from the dish squarely in the middle of the MoCA frequency band, so you had to configure MoCA to a different channel in DirecTV houses than e.g. The cable/satellite vendors needed the deterministic performance of MoCA (vs WiFi) and they were always planning on putting a box in every room with a TV - which generally already aligns with where the cable taps are. That's where almost all MoCA networking chips made ended up. The main "customer" for MoCA chips was cable set-top-box vendors (Scientific Atlanta, etc.) for "multi-room PVR" products. If you need connectivity in the garage/attic/closet/kitchen, MoCA might require new wires anyway. ![]() Also, MoCA is limited to places you have coax, which is usually bedrooms & living rooms. For MoCA, you have to buy & install a box for every endpoint. ![]() so mostly all you have to do to get wireless networking is buy the router. WiFi is still easier to install (where you can get a good signal), and built into phones/laptops/etc. I think there were a couple of contributing factors: ![]()
