BTI Communications Group designs, installs and supports commercial network installation in DuPage County, including Naperville, Wheaton, Downers Grove, Elmhurst and nearby cities. We pull and certify copper and fiber, install racks, switching, firewalls and Wi-Fi, and leave a test report and as-builts, including in occupied buildings. Work is served from our Downers Grove office.
Local engineers, 24/7 NOC/SOC monitoring and ISO 27001 compliant processes for DuPage County organizations. BTI Communications Group has over 40 years in business. Naperville corporate campuses, Wheaton professional offices and Downers Grove industrial sites often need cabling, Wi-Fi and racks installed around an occupied operation.
A Naperville campus, a Wheaton office and an Elmhurst industrial suite each need different drop counts, pathway rules and closet layouts. Sites along I-88, I-355, I-290 and Roosevelt Road are served from the Downers Grove office, often 5 to 25 miles from most DuPage communities.
Picture a Naperville campus adding a records suite in Wheaton and a warehouse closet in Elmhurst, with mixed cabling and no current test report. Start with a drop list a facilities or IT manager can read: each closet, each conference room, the fiber path between buildings and the circuit handoff. Confirm riser and after-hours rules with the landlord. Then pull new copper and fiber, certify every run and cut over after the workday. Leave labeled panels and as-builts when the job is done. For a Downers Grove industrial suite, the acceptance test might follow a shop closet from rack to a working dock office jack. For an Oak Brook professional floor, it might follow a new IDF from rack to a certified conference room drop.
In 87 seconds, Eric Brackett explains how BTI's DuPage County crews handle risers, building engineers, union and prevailing-wage sites and winter schedules, so cabling is ready by move-in day. Press play.
Installing network cabling in DuPage County? From a Naperville campus closet to a distribution suite in Addison or Woodridge, cabling is the part of your network you only want to pay for once. I'm Eric Brackett, Founder and President of BTI Communications Group.
I founded BTI in 1985 installing business phones. Over 40 years later, your IT, cybersecurity, cameras, door access, phones and AI share one network, with one accountable partner for it all.
Our DuPage County crews know how these buildings work: riser access, building engineers, freight elevator windows, union and prevailing-wage job sites, and winter schedules. We install Cat6 and Cat6A, fiber backbones, Wi-Fi, and Cisco Catalyst and Meraki switching.
Every cable is terminated, labeled, tested and certified, and we coordinate with your general contractor and carriers, so circuits and cabling are ready before move-in day.
BTI is a Cisco Select Partner, an ISNetworld member and ISO 27001 compliant, with 100 percent financing on qualifying projects. After go-live, our 24/7 NOC/SOC can monitor it.

DuPage County building stock ranges from corporate campuses in Naperville and Oak Brook to mid-century professional offices in Wheaton and Elmhurst and industrial parks in Addison, Carol Stream and Woodridge. Each needs a different installation approach.
Multi-tenant office installations depend on the building as much as the tenant. Before the first cable is pulled we coordinate with property management and the chief engineer on:
We also manage the building entrance and riser path for your carrier circuits, which is often the longest lead-time item on an office move.
Many DuPage County commercial projects, especially large tenant improvements, public-sector work and new construction, run under union or prevailing-wage requirements. Tell us your site requirements at the start and we will staff and document the project to match, so the general contractor never has to stop work over labor questions.
Outside the city, the challenge shifts from access to scale. Warehouses and industrial parks in Addison, Carol Stream, Westmont and Woodridge need high-bay access point mounting, long fiber runs, industrial-rated enclosures and Wi-Fi tuned for racking, scanners and forklifts. We plan lift access, work around picking shifts and design coverage for dense steel environments.
Schools, healthcare campuses and corporate parks across DuPage County often need fiber between buildings, either through existing conduit or new underground or aerial paths. We survey, install and certify inter-building fiber and plan around the freeze-thaw cycles that make DuPage County outdoor work seasonal. We also provide network and IT services in Oak Brook and other DuPage office corridors from our Downers Grove office.

Already know what you need? We'll build to your drawings. Still deciding? Our DuPage County network design team can produce the architecture and bill of materials first.
BTI is an ISNetworld member for clients and general contractors that prequalify contractors through it, and we carry the insurance DuPage County landlords require. We are ISO 27001 compliant, and once your network is live, our 24/7 NOC/SOC can monitor it. That NOC has handled more than 10,000 alerts with zero missed.
Your installation team can become your support team. Choose network monitoring, managed network services or full managed IT services in DuPage County, with a one-business-day engineer response for on-site needs anywhere in DuPage County. It's one reason 98 percent of our managed IT clients renew.

Office moves take longer than most tenants expect, mainly because of building approvals and carrier lead times. A typical timeline we plan against:
Suburban and industrial projects can move faster when we have direct building access, but carrier lead times still set the pace.
We price from a site survey rather than a rate card, because DuPage County projects vary widely. The main factors are drop count and cable category, distance to telecom rooms, ceiling and wall construction, riser and core-drill requirements, after-hours or union labor rules, lift requirements for high-bay warehouses, outdoor or inter-building fiber, and the switching and Wi-Fi hardware selected. Your proposal itemizes each, so you can see where the money goes, and 100% financing is available on qualifying projects.
Old masonry walls in converted lofts, steel racking in distribution centers, and glass-walled conference rooms in new office buildings all affect wireless differently. We survey before we install and validate after, adjusting access point placement, channel plans and power so coverage holds up when every seat and scanner is in use. For warehouses, we design for roaming handhelds and vehicle-mounted terminals; for offices, we design for dense video calling.
Our DuPage County crews work in active offices, clinics and plants every week. That means badge-in procedures, clean work areas at the end of every shift, respect for patient and client privacy, and clear communication with your on-site contact. We protect finishes, remove debris and leave telecom rooms better organized than we found them.
DuPage County installations involve a lot of moving parts: building engineers, riser access, carriers, general contractors and, on many sites, union labor rules. Each separate vendor adds another schedule to align and another set of people to coordinate. When BTI handles more of the scope, the price per item usually goes down, not up, because the design, installation, configuration, testing, commissioning, quality control and project management are done once, by one team, for everything.
A bundled DuPage County project can include:
Whether it's a Naperville office move or a new warehouse in Addison, when BTI coordinates and has authority over more of the value chain, the network goes in better, faster and less expensively, with fewer handoffs between the people pulling cable and the people running the network.

BTI Communications Group designs and installs commercial network cabling, fiber and Wi-Fi across DuPage County, including Naperville, Wheaton, Downers Grove and Elmhurst. We work from a written scope, test and label each drop, and hand over a port map. Call IT sales at 312-492-2613.
Cost depends on drop count, Cat6 or Cat6A, fiber runs between closets, ceiling access, after-hours work and how much existing cabling can be reused. BTI walks the site and gives an itemized written quote before work starts. We do not publish a standard package price.
A typical project includes a site walk, a written scope, certified copper and fiber, racks, switching, Wi-Fi, firewalls as scoped, labeled panels, a test report and as-builts. The exact bill of materials is written after the walk, not before.
Timing depends on drop counts, pathway access and whether the building is occupied. A small office can move quickly after the walk. A warehouse or multi-closet campus is scheduled in phases. We put the schedule in the written scope.
Yes. We schedule cable pulls and cutovers after hours or in phases so offices, docks and closets stay usable, and we confirm building access rules before work starts.
Illinois does not issue one statewide license for data cabling, and permit rules vary by city, so BTI confirms permits for each site during the site walk. BTI holds Illinois security license 127.001638 for security work.
No. Structured cabling is low-voltage data work: copper, fiber, panels and test reports. An electrician may run power or a single cable, but a certified network installation is planned, labeled and tested as a system. BTI performs the low-voltage installation and coordinates with electrical trades when a closet needs power.
Design decides closets, drop counts, cable types, switching and Wi-Fi before anything is pulled. Installation is the certified plant, the racks and the cutover. BTI does both so the drawings match what is left in the closet.
No. An ISP usually hands off a circuit at a demarc or a single jack. Network installation is the certified cabling, racks, switching, Wi-Fi and documentation inside the building that your users actually connect to. BTI can coordinate the circuit and the inside plant so both sides meet cleanly.
Yes. BTI assesses existing cabling, switches and Wi-Fi, fixes what fails testing and plans upgrades. Ongoing support includes our 24/7 NOC/SOC and SLAs with 4-hour onsite emergency response under BTI support agreements. Emergency support is available 24/7. Call 800-435-7284.
4-hour onsite emergency response is available under BTI support agreements. Emergency support is available 24/7. Call 800-435-7284.
Yes. 100% financing is available on qualifying projects, covering hardware, licensing and labor, and 3.99% financing is available on Cisco Meraki hardware, subject to credit approval. We review options during the proposal.
BTI is a reseller and installer, not a distributor. We quote switches, access points, cabling, licensing and labor together, so one team owns the result from purchase through support.
Yes. BTI sells and renews network licensing, including Cisco Meraki, and plans switch and Wi-Fi refreshes so licenses, firmware and hardware stay supported.
BTI installs networks for healthcare, logistics and warehousing, manufacturing, education, government, financial services and parking venues, each with segmentation and documentation suited to how the site runs.
Yes. Segmented VLANs, documented port maps, labeled cabling and change records make audits such as PCI DSS easier to support. BTI processes are ISO 27001 compliant, and our IT compliance team can help with formal programs.
BTI has been in business for over 40 years. Since 1996, BTI has installed and supported network infrastructure for VoIP and business networks, including cabling, switching and the paths those systems need.
Corporate campuses in Naperville, Lisle and Oak Brook need documented closets, reliable Wi-Fi and after-hours cutovers. Professional offices in Wheaton, Glen Ellyn and Lombard need tenant improvement installs that do not interrupt the workday. Industrial and distribution sites in Addison, Carol Stream, Westmont and Woodridge need long fiber runs and organized racks. Civic and community sites in Elmhurst and Downers Grove need clear as-builts and a local office that can return when something changes.
