Teleste: Data over Coax - quality service at lower costs

Fibre to the Home would provide sufficient speeds, but bringing fibre connections to people's homes is far too expensive in a typical European apartment building. However, there is a simple solution. Data over Coax (DoC) provides a versatile and cost efficient alternative for bringing high-speed broadband connections to customers by using existing coaxial cabling - for under one-fifth of the price compared to FttH. In this whitepaper, we discuss Data over Coax's architecture and the merits of different DoC technologies.

Background
Changing TV consumer habits and the migration from
linear TV to on-demand services (OTT, IPTV or unicast DVB, VoD, catch-up, NPVR, etc.) will drive broadband connectivity speeds to a new level. This is being further accentuated with the emergence of new video formats (HD, Ultra-HD, 3D).

A downstream speed of 10Mbps is no longer adequate for a high-quality consumer experience - within the next five years, operators will have to
offer guaranteed speeds of at least 30Mbps to each customer, and even 100Mbps per customer will be normal.

The most likely model to deliver these services will be some type of over-the-top delivery - meaning that the back-office service platform will be able to deliver TV content over unmanaged broadband access networks and into retail market consumer devices.

The drivers for OTT delivery are as follows:
• Mobile TV services can be off ered - both in-home and while on the go
• The service can be marketed to all consumers - not only to those who are connected via the service provider's own access network
• The service can be made compatible with various types of end devices
• The creation and management of the service can predominantly be done in the back-office / cloud, with the benefit of limited software complexity at the end-user device level.

This Teleste white paper looks at addressing these issues.
