Communications infrastructure that just works.
VKTEK designs, installs and supports the systems your business relies on every day: phone systems, secure networks and in-building mobile coverage. One team from design through to ongoing support.
What we do
Four disciplines, one accountable partner
Voice, data, security and coverage depend on each other. We design them together so they work together, and we stay around after go-live to keep them running.
Networking
Fast, reliable wired and wireless networks, from a single office to multi-site organisations.
- Switching, routing & VLAN design
- Wi-Fi design: predictive & on-site surveys
- Wi-Fi heatmaps & post-install validation
- SD-WAN & multi-site VPN
- Structured cabling coordination
Cyber Security
Practical, layered protection that keeps threats out without getting in the way of your staff.
- Next-generation firewalls
- Zero Trust (ZTNA) & secure remote access
- Endpoint protection & MFA
- Security reviews & hardening
Cellular RF Solutions
Strong, carrier-grade mobile coverage inside your building, powered by Nextivity Cel-Fi.
- RF site surveys & coverage design
- Cel-Fi GO & QUATRA systems
- Telstra, Optus & Vodafone networks
- Installation, commissioning & monitoring
In-building mobile coverage
No more dropped calls inside your building
Modern buildings are great at keeping mobile signal out. We bring it back in, legally and reliably, with Nextivity Cel-Fi smart signal boosters.
Low-E glass, concrete & steelEnergy-efficient building materials block cellular signals, leaving dead zones in offices, warehouses and basements.
Unreliable calls & slow dataMissed calls, failed MFA codes and patchy data cost time and frustrate staff and customers.
Safety & complianceLone workers, sites and emergency procedures depend on a phone that works everywhere on the premises.
Cel-Fi products are network-safe and approved for use on Australian carrier networks. We'll confirm which carriers and bands suit your site during the survey.
Small to medium sites
Cel-Fi GO
A high-gain smart repeater for a single carrier. Ideal for offices, homes, retail, rural properties and vehicles where one network needs a serious boost.
Medium to large buildings
Cel-Fi QUATRA
An active distributed antenna system (DAS) that delivers multi-carrier coverage over standard Ethernet cabling. A cost-effective alternative to traditional passive DAS for offices, hospitals, hotels and warehouses.
Our process
Survey → Design → Install → Monitor
We measure the donor signal, design for your floor plan and carriers, install and commission the system, then verify coverage with you on site.

About VKTEK · Est. 2008
Hands-on engineers, not just resellers
Since 2008, VKTEK has been helping Australian businesses stay connected. We are a communications and technology company specialising in voice, networking, cyber security and cellular RF. We work across the full stack, from the phone on the desk and the firewall in the rack to the mobile signal in the basement.
Because we understand how these systems interact, we solve problems that single-discipline providers can't, and we give you one point of accountability when something needs attention.
