Solutions

The right infrastructure starts with what you need to achieve.

Calls that drop indoors, networks that struggle at busy times, or coverage threatened by a site loss: similar frustrations can need different responses. Ontix brings assessment, technology and delivery experience together to help establish the right approach for your location and the people it serves.

Understanding the requirement

Not every signal problem is the same.

Understanding where service falls short is the first step towards improving it. These three questions help frame the requirement; assessment establishes the cause and the options worth considering.

  • Coverage

    Does the mobile signal reach the areas people need to use? Building materials, layout and the surrounding network can all affect availability.

  • Capacity

    Can the mobile network support demand when people use it? A visible signal does not necessarily mean enough capacity at busy times.

  • Guest internet access

    Do visitors need an internet connection through Wi-Fi? This is a separate service requirement that can complement mobile connectivity.

The Ontix range

Different solutions. Coordinated around your requirement.

Outdoor and indoor systems address different coverage and capacity needs. Public Wi-Fi provides a separate internet access service, while our platform and delivery capabilities support the agreed deployment. We assess which elements are relevant and how they need to work together.

01
On the street

  • Small cells

    Extra mobile capacity on street furniture, right where crowds gather.

    Compact base stations on lamp posts and other street assets work alongside the larger masts nearby. Each site also needs power, a link back to the network and the operator’s agreement, which we assess alongside the radio design.

    About small cells

  • Temporary Small Cells

    Interim cover for priority areas when a mobile site is lost or at risk.

    A planned cluster of small cells on existing street assets keeps the most important areas served while a permanent replacement progresses. A feasibility review shows whether it can work in the time available.

    About Temporary Small Cells

02
Inside buildings

  • Intra

    Indoor mobile coverage for offices, shops and venues, planned around each space.

    Intra is Ontix’s indoor mobile solution. It’s installed around how each floor is used and linked to the networks of participating operators.

  • Distributed antenna systems (DAS)

    Mobile coverage carried throughout large buildings, venues and campuses.

    A DAS takes signal from agreed sources to antennas across the site. Which networks take part, and the capacity each provides, are agreed as part of the design.

    About DAS

03
In public spaces

Public Wi-Fi

Internet access for visitors in streets, venues and public spaces.

Designed around how many people use a space, when they use it and who runs the service. It works alongside mobile networks, not instead of them.

About public Wi-Fi

04
Platform and delivery

  • Ontix Nexus

    The neutral host gateway linking shared infrastructure to each participating operator.

    The Neutral Host Service Gateway connects shared radio infrastructure with participating mobile operator core networks. It enables an agreed network model; it is considered alongside the radio design and operator arrangements.

    About Ontix Nexus

  • Infrastructure and build services

    Design, build and ongoing management of the infrastructure behind a deployment.

    Site access, physical works, power and fibre, delivered to a defined scope with clear responsibility for each part.

    About infrastructure and build

Shared infrastructure

One installation, more than one network, where operators agree.

A neutral host approach allows participating mobile networks to use shared infrastructure. Where technically and commercially appropriate, this can reduce duplication of equipment and supporting works. The design establishes what is shared, how operators connect and who is responsible for each part.

What it means:

  • For operators: a route to additional coverage or capacity using shared infrastructure, subject to technical and commercial agreement.
  • For councils and property owners: an opportunity to coordinate infrastructure within the available space and reduce separate installations where feasible.
  • For the people using it: improved mobile service on the networks participating at that location.

Operator participation and service availability are specific to each deployment. We establish these requirements with the relevant parties as part of assessment and design.

How we work

From understanding the requirement to supporting live infrastructure.

  1. Define

    Establish what needs to work, where and for whom, including the mobile networks or guest access service required.

  2. Assess

    Review radio conditions, available assets, connectivity, power, access and permissions.

  3. Design

    Develop the approach, agree responsibilities and establish the applicable operator and customer acceptance requirements.

  4. Deliver

    Coordinate installation, commissioning and handover against the agreed scope and acceptance criteria.

  5. Manage

    Provide ongoing monitoring and maintenance within the agreed service scope, with clear responsibilities for faults and changes.

The scope and sequence depend on the solution. Delivery times are shaped by site conditions, operator requirements and the dependencies identified during assessment.

In practice

Small cells at Trafalgar Square.

Trafalgar Square shows how a capacity requirement shaped the infrastructure response. Ontix used access to street furniture through Westminster City Council to deploy small cells for Vodafone, with five sites later upgraded to add 5G.

Sectors

Mobile coverage and capacity, built around your sector.

A busy network, an underserved town centre, a building where calls drop: connectivity pressures take different forms. We understand what is at stake for your organisation and the people who depend on it. Explore how we help your sector turn those pressures into a clear plan for improved connectivity.

Discuss your requirement

Mobile network operators

Meet growing demand. Address gaps in service.

The pressures you face

  • Demand concentrates in busy locations where new macro sites can be difficult to secure and deliver.
  • An established site is lost or at risk following a Notice to Quit (NTQ), putting continuity of service under pressure.
  • Customers move indoors, but the mobile experience does not always follow them.

How we help

We work alongside your network, acquisition and delivery teams to establish the coverage or capacity required and the constraints that shape delivery. Outdoor small cells, Temporary Small Cells and indoor systems provide different ways to address that requirement. We bring site access, power, transmission and deployment together around your specifications and acceptance process, with ongoing infrastructure management after go-live.

Local authorities and public sector

Help your communities connect to everyday opportunities.

The pressures you face

  • Busy town centres and visitor areas where mobile service struggles when people need it most.
  • Regeneration and new developments that need connectivity considered alongside other infrastructure.
  • Public buildings with poor indoor signal, and pressure to improve street coverage without adding unnecessary clutter.

How we help

We work with your highways, estates and building teams to assess where public assets can support improved connectivity. Small cells on suitable street furniture, indoor mobile systems and public Wi-Fi serve different needs. Our experience with operator requirements, access and delivery helps you plan an approach around residents, local businesses and visitors. Where the design and operator agreements allow, shared mobile infrastructure can support more than one network.

Enterprises, venues and campuses

Support the people and operations in every space you manage.

The pressures you face

  • Coverage varies between buildings or floors, interrupting calls and everyday work.
  • Events, match days and shift changes concentrate demand beyond what the existing service can support.
  • Staff, tenants and visitors use different mobile networks, alongside a separate need for guest internet access.

How we help

We start with how your site operates: who uses it, where coverage falls short and when demand changes. Our team assesses the layout, capacity and mobile networks required, then develops an approach using indoor systems, outdoor small cells or a combination. Operator participation shapes the mobile service; public Wi-Fi can provide a separate guest service. We plan delivery and ongoing management around your operational requirements.

The pressures you face

  • Missed calls and interrupted payments where terminals rely on mobile data.
  • Staff who need their phones for customer enquiries and everyday work.
  • Limited time to investigate the cause or manage a complex installation.

How we help

We help establish why mobile service falls short inside your premises and what would improve it. Intra can bring indoor coverage to suitable shops, offices and venues for participating mobile networks, with ongoing management from Ontix. We assess the networks, layout and demand before recommending an approach, and explain when another option, such as Wi-Fi calling, may be sufficient.

People and partnerships

The right people, involved from the start.

Connectivity projects can stall when access, approvals and operator requirements are considered too late. Our team brings experience of working across these dependencies, helping you establish who needs to be involved, what must be agreed and how delivery can move forward.

Experience:
From initial assessment to live service, our team understands the decisions and dependencies that shape delivery.
Relationships:
We work with operators, councils, property stakeholders and delivery partners to bring the relevant people into the conversation.
Clear coordination:
Early attention to permissions, access and responsibilities helps identify obstacles before they delay deployment.

How we help

Better mobile coverage and capacity, planned around places and people.

A signal on a phone doesn’t show whether the network can cope with everyone using it, or whether it reaches inside a building. That’s where Ontix starts: what does this place need from the mobile network, and when?


From there, we plan the right mix of infrastructure: small cells on street furniture, indoor mobile coverage, distributed antenna systems (DAS) and public Wi-Fi. Where the design and operator agreements allow, shared neutral host infrastructure lets one installation support more than one mobile network.
