Our experience in planning wireless networks for wireless ISPs, from small network segments to district-wide deployments, helps give insight into feasibility, costs and designing deployable solutions.
Working with mixed media (fibre and wireless) and frequencies (lightly licensed 5 GHz access layers and licensed backhaul) we can help design and assess solutions that are affordable, deliverable and sustainable for future network growth.
Next Generation Access (NGA) Documentation & Conformity
Working with several networks, we have been integral in assessing, documenting and planning NGA conformity in line with BDUK’s standards. We have experience in requirements from solution design and hardware selection to business modelling for financial sustainability and can help you document and submit this information.
NGA assessment is key, both for networks looking to protect their deployments from overbuilding via OMR submissions and WISPs looking to tender for public intervention areas.
We can help prepare OMR and NGA submissions and advise on the requirements of these processes.
We look at:
- Network longevity.
- Financial viability and planning.
- Capacity requirements and dimensioning.
- Quality assurance.
5 GHz Last Mile
Using OS and AddressBase data, we assess viable access point locations. Radio selection, subscriber density and throughput requirements are built into the design, along with local sensitivities such as visibility and height. The National Tree Map can be used to help build confidence in solution design, and background RF monitoring prior to deployment helps plan for frequency use.
When selecting locations, RF stability and coverage levels within line of sight are not the only variables. The likelihood of being able to install at a location and access backhaul, power and other services are factored in, reducing the time spent liaising between desktop and physical surveyors and increasing deployment confidence.
Modelling of deployments allows us to predict and model jitter and latency calculations, and provide KPIs against which to monitor and assess the network’s performance.
Backhaul Design & Dimensioning
We look at the wider network and deployment area to determine the best backhaul routes and locations. How fibre, lightly licensed and fully licensed radio links can be deployed to achieve reliability, redundancy and viable OPEX costs within each customer’s parameters are analysed from the start of the process, with detailed traffic analysis and forecasting informing these decisions.
Backhaul dimensioning shows where future bottlenecks could develop and how these can be mitigated.
We have experience working from small village deployments of around 30 premises to public intervention tenders across entire districts.
Frequency Reuse & Optimisation
The combination of higher use of (and thus higher background noise levels in) the 5 Ghz spectrum space and greater demand for bandwidth from end users is pushing the importance of getting the maximum out of the limited spectrum available.
Frequency reuse through GPS synchronisation and other timing mechanisms is allowing WISPs to use higher bandwidth channels for the delivery of both superfast and ultrafast services. However, this brings with it issues around DFS channel hopping, equipment selection and area planning. With careful deployment planning, we can help you overcome these challenges and understand the risks/rewards different solutions offer.
Cost Analysis & OPEX Reduction
As wireless networks scale and decentralise, keeping key metrics like latency, jitter and connection down while balancing the cost of higher OPEX licensed and fibre backhauls becomes harder.
Understanding how the network and traffic demands are likely to grow is key to working out where to deploy or redeploy higher capacity connectivity. Solutions like longer range e-band links with licensed fallback can help keep Ofcom licence fees down.
We can help with the data collection and analysis needed to form this design.
Building redundancy into wireless networks, particularly at the last mile access layer, can be harder than in traditional fibre/cabled networks. Planning longevity into your network and understanding the scaling barriers that may arise from the initial deployment help minimise the need for downtime as the network expands.
Specifying hardware that balances capital expenditure costs with the medium- and longer-term needs of the network is a key part of the wireless network link design process. Understanding the variance in different options, and what drawbacks come with some solutions (such as rain fade), helps predict how the network will perform once deployed.
