2. Introduction

Wireless networking may get most of the attention these days, but there are still technologies competing to replace Ethernet as the primary home networking method. And those technologies may yet have a chance, because wireless still suffers from reliability, reach and Quality of Service (QoS) problems that keep it from being wholeheartedly adopted by service providers as a primary in-home networking technology.

But proponents of powerline, phoneline and unterminated coax networking haven't exactly been rushing products to market that can satisfy the requirements for reliable multimedia home networking either. There are encouraging signs that member companies of the official industry organizations for powerline and coax networking (HomePlug and Multimedia Coax Alliance - MoCA) are on the verge of shipping spec-compliant products capable of transporting multiple video streams around your home. But products remain in field trials, and specs are generally not yet finalized.

Home PNA is the only group of the three to have released its multimedia-capable phoneline spec (

But where there's market void, there will always be companies to fill it. Corinex appears to be in that camp with its "AV" series of phoneline, coax and power line adapters, which use a combination of standard and non-standard technologies. In this review, I'll look at their AV Phoneline Ethernet Bridge and AV CableLAN Adapter.
