NLoS WIRELESS
"We were impressed with the results over the short distance radio link tests.
The system met our expectations for QoS and cost and we found it very easy to set up and use with our field measurements."
Tim McDonald, Technical Services Manager, Nine Network
THE PROBLEM
Our reliance on cable technology is simply not economically feasible in our local market due to our geography, urban sprawl and our ever-increasing appetite for the internet. We've partnered with the best of breed Fibre networks from where we deploy our unique ultra fast NLoS wireless solution so your customers can experience the internet the way it should be experienced
OUR
SOLUTION
Today’s wireless access technologies (Wi-Fi, 4G, even forthcoming 5G systems) use a “roughly-right” approach to sending and receiving radio signals, so they can’t avoid interference or adapt fast enough to dynamic environments. Wind in the trees, cars and trucks, and interference all continually change the wireless environment, causing wide variations in speed, jitter, and latency for conventional radios. Ours is the only system that dynamically adjusts, thousands of times per second, to ensure consistent and precise control over radio signals and a fibre-quality experience, without the fibre costs.
As with all new technology, any wireless alternative to outdated copper and expensive fibre in the “Last Mile” must overcome all five of these challenging issues:
01
OBSTRUCTIONS
Connecting radios in perfectly clear, clean, and stable line of sight conditions is easy. Unfortunately, the real world of the “Last Mile” — especially in residential areas — makes this impossible much if not most of the time,
* because of structures and foliage in the way. The prevalence of this non-line-of-sight (NLoS) problem has profound implications for successful wireless system design.
02
SPECTRUM SCARCITY
Most important, working around obstructions requires radio spectrum with the right propagation physics — i.e. bands in the 1 to 6 GHz range. Availability in this spectrum is very limited, given its already widespread use for commercial and government mobile services. Any broadband wireless access (BWA) solution must achieve a very large increase
in spectral efficiency over the current state of the art in order to deliver gigabit service in limited spectrum. [Note that inherently poor propagation in the more lightly-used mm-wave bands being explored in current 5G research limits their use to very short LoS links, precluding a viable solution to problem #1 in fixed access.*]
The Global Broadband industry currently stands at $620USD billion per annum. An outstanding opportunity exists for the Australian market to access this industry however is currently being held back by a lack of available ‘High Speed’ internet access.
Horizon wireless has the solution. We have recently been appointed the exclusive distributor of Tarana Wireless technology for the Pacific Region.
We offer carriers and service providers the opportunity to extend their “Last Mile” connectivity to customers through our unique wireless service that delivers super-fast broadband speeds at a fraction of the cost of traditional Fibre and Cable Broadband.
Our products and services operate over licensed and unlicensed spectrum and most importantly will deliver high speed broadband speeds of 200Mpbs and 400 Mbps over Non Line of Site (NLoS). Immune to obstructions, interference, motion, and unskilled installers with unprecedented spectral efficiency, our products will revolutionise the way Broadband is delivered in Australia and the Region.
03
INTERFERENCE
The interference issue for BWA systems comes in two flavors. First, inter-cell self-interference within a BWA network must be carefully managed in order to maintain full gigabit service to the cell edge (overcoming one of LTE’s inherent limitations), and to maximize spectrum re-use. Second, since the limited availability of sub-6 GHz spectrum drives most fixed access applications into the unlicensed 5 GHz band, a system must contend successfully with random, pervasive interference from other networks.
Maintaining quality service in the face of this widespread issue requires a substantial improvement on the industry’s default approach — evasive channel-changing — which fails in the ever-increasing share of situations where the band is fully busy (just like lane-changing at the peak of rush hour on your worst stretch of urban freeway).
04
MOTION
Although perhaps counterintuitive for an access system with fixed endpoints, motion in the environment is a problem as well. The RF obstructions and reflected signals involved in NLoS operation change as the physical environment changes — whether quickly (from passing vehicles or wind-blown foliage), slowly (foliage growth, new construction), or episodically (holiday decorations). A BWA system must adjust to these changing conditions rapidly and autonomously.
05
COMPLEX INSTALLATION
Last but certainly not least, for a BWA solution to scale up to deployments covering millions of households, and quickly, it must be much easier to install than conventional radio networks — on both ends of the link.
Rather than dressing up off-the-shelf radio elements with incremental engineering half-measures and filling the resulting performance gap with false advertising, as is the common practice in the industry, our technology partner, Tarana did the ground-up algorithm invention and refinement, combined with complex whole-system engineering, required to actually solve all five of the hard BWA problems in a commercially-viable 5G architecture.
The outcome of this effort is the Horizon Broadband Access Platform. It allows Horizon the ability to deploy high speed internet easily across a broad range of applications.
