    Network Infrastructure

    Network infrastructure services, built on purpose.

    Your network is the thing everything else runs on, and it wears down quietly. Dead zones creep in, the gear ages, one cut line takes a site offline. We design, tune, and secure it for operations where being down is not an option.

    Where networks break

    A network only gets noticed when it stops.

    A good network is invisible. It wears down a little at a time, and the first real signal is usually a user complaint or a site that drops offline mid-shift, long after the problem set in. Wireless drifts the fastest, which is why most engagements begin with a site survey, the easiest place to start.

    Here are some of the kinds of problems we solve:

    • One link is a single point of failure.A fiber cut or an ISP outage shouldn't take a site dark. Cellular failover and redundant paths keep it running.
    • Routing is a trust system, and trust gets abused.For ISPs and larger networks, a bad route announcement can pull your traffic off course. Securing how routes are advertised and accepted is its own discipline.
    • The address space is running out.IPv4 is gone, and a network with no plan for IPv6 is on borrowed time. Planning the move now is cheaper than forcing it later.
    What we do

    Four things that decide whether a network holds.

    Here is what keeps a network fast, reachable, and out of your way.

    Wireless that holds up under stress.

    It starts with a site survey: heat mapping, coverage analysis, RF and spectrum work, interference and rogue access point detection, and the right access point placement for how the space gets used. You come away knowing exactly where the signal fails and why, with a short list of what to fix first.

    Switching and routing that don't flinch.

    High-performance switching and routing built on Arista, designed for campus networks, data centers, and the operations that depend on them. Spine-leaf fabric, segmentation that keeps traffic where it belongs, and performance tuned to throughput you can measure. Enterprise networking that keeps up as you grow.

    Connections that stay up.

    Cellular failover for remote and critical sites through our Cradlepoint and AT&T partnership, so one cut line doesn't take a location offline. BGP security through Routing Shield, our MANRS-compliant platform, for the ISPs and larger networks that need their routing protected. IPv6 deployment through Get 6'd when you've run out of IPv4 addresses. For ISPs, IP Fortress handles DNS, DHCP, and IPAM in one managed appliance.

    A design and a plan before you spend.

    A network assessment and a real design come before the purchase order. We map what you have, find the gaps, and design the network you need, then size the spend to it. The goal is the gear you need, placed where it earns its keep, sized to your design rather than a vendor's catalog.

    Where to start

    How a network project runs.

    Most networks fail in a handful of predictable places, and this is how we identify and execute on the right solutions.

    1. 1

      Assess

      We survey the wireless, map the wired network, and find the gaps. You get a findings report you keep, whether or not the work continues with us.

    2. 2

      Design

      We design the network around how your operation runs, size the hardware to the design, and tell you plainly what is worth spending on and what isn't.

    3. 3

      Deploy

      We do the build with your team, not around them, and we keep the work scheduled around the hours you can't afford to lose.

    4. 4

      Monitor

      Through Overwatch, our monitoring overlay, we watch performance and flag problems before your users do, so the network goes back to being invisible.

    How we work

    We do the work with your team, and we teach as we go.

    • We train your team on what we're doing.Your people should come out of every project more capable than they went in. Dependency is not our business model.
    • You get direct access to the engineer doing the work.No account manager in the middle. The person you talk to knows your network.
    • We're transparent about what things cost.Hardware, licensing, labor. When a different approach saves you money, we say so.
    • We'd rather earn your business than lock it in.Most of our clients have stayed with us more than a decade, by choice.

    Sectors we specialize in

    Built for utilities, ISPs, municipalities, and the teams that keep them connected.

    We design and secure networks for the operators communities run on, where coverage and uptime are not optional.

    Electric utilities and cooperatives.

    Substation connectivity, SCADA networks, and the segmentation that keeps operational traffic separate from the office. Networks built for sites that can't go quiet.

    ISPs and telecom providers.

    BGP security through Routing Shield, IPv6 deployment through Get 6'd, and DNS, DHCP, and IPAM through IP Fortress. The network depth built for the providers who keep their communities online.

    Municipalities and county governments.

    City halls, public safety networks, and fiber builds through our LitFiber partnership, all on a public budget. Coverage and reliability the residents never have to think about.

    Water and wastewater authorities.

    Remote site connectivity, cellular failover, and monitoring for treatment plants and pump stations run by small teams with wide footprints.

    Manufacturing.

    Plant-floor networks where a dropped connection stops a line. Segmentation, wireless that holds up in a hard environment, and uptime designed around production.

    Growing enterprises.

    Campus and multi-site networks that have outgrown the build they started with. Enterprise networking, redesign, and the assessment that tells you where you stand.

    Common questions

    What teams ask before they call us about the network.

    Network infrastructure services cover the design, deployment, security, and ongoing care of the systems that move your data: wireless, switching and routing, the connections to the outside world, and the addressing and DNS underneath. The goal is a network reliable enough that you stop thinking about it. At LightChange that includes wireless site surveys, Arista switching and routing, cellular failover, BGP security, and IPv6 deployment, designed and tuned for operations where uptime is the job.
    A wireless site survey measures how your Wi-Fi performs across your space. It maps coverage and dead zones, analyzes interference and RF spectrum, checks access point placement, and looks for rogue access points and security gaps. You come away with a clear picture of where the wireless is weak and what to fix first. It is the fastest, lowest-cost way to turn "the Wi-Fi is bad" into a real plan, which is why it is our recommended first step.
    A network assessment is a structured review of your wired and wireless network: what hardware you have, how it's configured, where the bottlenecks and single points of failure are, and where the security gaps sit. It produces a findings report and a prioritized list of what to address, and it's the diagnostic we run before designing or buying anything. You keep the report whether or not the work continues with us.
    LightChange does. We run the full wireless evaluation: a site survey with heat mapping and coverage analysis, RF and spectrum analysis, throughput and latency testing, access point placement, rogue AP and security checks, and the option to monitor performance after the work is done. The survey is vendor-neutral, so the findings are about your network, not a product we're trying to sell.
    LightChange specializes in high-performance switching and routing, built on Arista for campus networks, data centers, and operations that can't slow down. That includes spine-leaf fabric design, segmentation, and performance tuning for throughput and low latency. We've designed and run these networks for critical infrastructure operators across the continental US since 2004.
    Cellular failover keeps a site online when its primary internet connection goes down by automatically routing traffic over a cellular link until the main connection comes back. It's how a remote substation, a pump station, or a branch site stays reachable through a fiber cut or an ISP outage. We deploy it through our Cradlepoint and AT&T partnership, sized to the site's needs.
    BGP is the protocol that decides how internet traffic reaches your network, and it was built on trust, which means a bad or hijacked route announcement can pull your traffic off course. BGP security validates the routes your network advertises and accepts so that can't happen. If you're an ISP or you run your own routing to the internet, you need it. We deliver it through Routing Shield, our MANRS-compliant platform.
    Most providers sell you hardware and a support contract and call it a network. We design the network for how your operation runs, we work alongside your team and inside your operation, and we hand over the reasoning so your people get stronger. You're never locked into our stack or dependent on us to understand your own network. We also tell you when you don't need something, which a catalog-driven shop rarely will.
    We work alongside your team. We take on the design and the specialized network work your team doesn't do every day, and we teach as we go so your team comes out stronger. The network stays something they can run.
    We'd rather earn your business than lock it in. We steer away from long contracts unless a project genuinely calls for one. Most of our clients have stayed with us more than a decade, by choice.
    It's a scoped look at your wireless network: coverage and dead-zone mapping, RF and spectrum analysis, interference and rogue access point detection, and access point placement, with a findings report you keep. It's the same diagnostic we'd run at the start of a larger network engagement, and it gives you a clear picture of where you stand and what to do next, whether or not you work with us further.
    We're headquartered at 13000 Equity Place, Suite 205, Louisville, Kentucky 40223. We serve clients across the continental US. For critical infrastructure and ISP engagements, we travel where the work is.

    Not sure where your network is weakest? A survey will tell you.

    Tell us what you're running and where it's hurting, and you'll talk it through with an engineer who designs these networks. If we're not the right fit, we'll tell you who is.
