MoCA, HPNA and POF are other available options for the in-home IPTV market. These Technologies are under testing in my lab nowadays; due to the use coax technology has a marginal use with a low penetration level in Europe.
In the other hand, we have found some problems under odd circumstances that may imply not to recommend using them at this moment.
MoCA:
In spite of this technology has been introduced well into USA market due to historical cable operators and some other few American countries, there is no reference for great deployment into European Market. At glance, we can guess some issues that involve this technology:
• Marginal installation into European market.
• More suitable with a high cable networks penetration rate.
• Security is a problem: It does not support AES encryption.
• Service Providers must be careful with old pre-existing cable installations. Usually the work into a Do It Yourself environment, with defective existing installations.
• Complex Troubleshooting rises up due to unknown problems with amplifiers and active elements into the cable network.
• Restricted market to coax installations.
HPNA:
HPNA bring up with Telephony network to deploy an IPTV infrastructure at far end, but it introduced the Coax cable network with latest releases into the Alliance. Working with telephony lines, it carries only a few Mbps, so it is not a valid technology for HD IPTV support. By the other hand, with coax cabling support, it shares the same problems and network issues than MoCA:
• Marginal deployment into European market.
• More suitable with a high cable networks penetration rate.
• Service Providers must be careful with old pre-existing cable installations. Usually the work into a Do It Yourself environment, with defective existing installations.
• A few chipset manufactures available.
• Doesn't coexist with DOCSIS.
POF:
- Two options:
- POF - USB adapter (without AC power adapter)
- POF – Ethernet (with AC power adapter)
- Up to 30 meters.
- Easy installation, but high cost if technical installer is needed.
- Unmanageable.
Hi,
ResponderEliminarCurrently there are actually versions of both the HPNA and MOCA that can achieve more than 100 Mbps application layer throughput. That is HPNA version 3.1 (Physical layer throughput of 320 Mbps) and MOCA 1.1 (Physical latyer throughput of 270 Mbps). The actula application layer (TCP/IP) throughput is of course much lower.
In addition to these technologies there is also the possiblity of using PLC. A technology that was originally developed for the powerline but, as the case of HPNA, has been adapted to the coaxial cable.
The main advantages for PLC vs MOCA and HPNA is its robustness to noise (that might be present in the coaxial cable) and that it can reach longer distances (higher dynamic range) thus making it a technology more stable and more reliable for any type coax network.
The max application layer througput achivable for PLC technology is also similar to that of MOCA and HPNA.
