Last 100m Access Technologies

New applications are ever more demanding in terms of bandwidth. Both in households and businesses there is an increasing number of HD video devices, it is common to synchronize cloud data, and the volume of data keeps rising; speeds below 100Mbps are therefore no longer sufficient. We need to get close to gigabit transmission rates, or at least multiples of 100Mbps. Because of high costs, we are unable to provide a special optical connection for each user, so we need to get over the last 100m using the media currently available.

What are technologies that can offer up to 1Gbps bitrate across the distance of a few hundred meters? Are we able to provide connection for business and residential customers with different requirements for quality, guarantee, uplink/downlink ratio? How complicated is the installation? We can lay optical cables to relatively very close distance, with the last 100m to be covered. What are the media available to connect end users? There are metallic lines, and – of course – “the air”. We need access technologies for metallic lines; in case there is no metallic loop, wireless connection must be used. We have a solution for both cases, G.FAST technology for metallic lines, and PMP@60GHz technology for the wireless connection.

What are the common features of G.FAST and PMP@60GHz technologies?

  • Bitrate of up to 1 Gbps
  • Distances of a few hundred meters
  • Easy installation using the existing media, with user-installable terminal devices
  • TDD for asymmetric connection configurable setup
  • A compact solution for a small number of connected users, designed to be placed at aisle-based switchboards
  • Very low latency times (<2ms)
  • Very low power consumption, optimized for idle periods

By combining G.FAST and PMP@60GHz technologies we can increase the connection throughput significantly, and most importantly, we can increase the number of connected users while maintaining reasonable capital costs. Users can thus enjoy – for an affordable price – bitrates normally only available via optical lines. Both technologies are new, currently being tested by several operators; G.FAST can be implemented straight away, while PMP@60GHz technology is subject to EU regulations currently being prepared, which makes this technology available for testing purposes only.
