Services
Wi-Fi and network service for homes and small businesses in Maumelle and Little Rock. Work happens at your home or business. Duku Engineering is preparing to launch, pending business approvals.
Wi-Fi and network services
Wi-Fi health check
We find out why your Wi-Fi isn’t doing its job. We look at coverage, router placement, interference, and whether the problem is your internet service or your Wi-Fi. Then we recommend a practical fix. Often that means moving or adjusting what you already have.
Router and mesh setup
Setup for the router or mesh system you own: firmware updates, secure administrator settings, a guest network if you want one, and reconnecting your devices. You keep the administrator account.
Home-office and small-office connectivity
Computers and printers connected and working on the network. Existing Ethernet connections tidied and labeled, so it’s clear what goes where.
Ethernet and low-voltage cabling
Small, accessible Ethernet runs and jack terminations. We look at the space before quoting cable runs, and quote them separately. Any permit or contractor requirements for a particular job are confirmed before that work starts.
Equipment
We’re a service business, not an equipment reseller. If your router or mesh system is adequate, we use it. If a replacement makes sense, we help you choose one from a retailer, so you own the equipment, account, receipt and warranty.
Pricing
You get a written quote before any work begins, covering labor, any materials, travel where it applies, and tax.
Availability
By appointment.
Helpful resource
Choosing Wi-Fi gear? Start with a practical checklist for your home, devices and existing setup—without pressure to replace equipment that still works.
What we don’t do
So you know up front, the following aren’t offered:
• Security cameras, alarm systems or video doorbells
• Electrical work, including new or relocated outlets, line-voltage wiring, or running TV power through walls
• 24/7 or emergency call-outs
• Managed security services, enterprise network migrations, fiber certification, or roof work
If you aren’t sure whether your job fits, ask. We’ll tell you plainly.
Engineering consulting
Separately from the Wi-Fi work, Duku Engineering offers signal integrity measurement and analysis for hardware teams. This is a later, smaller part of the business. Inquiries are welcome, and the scope is agreed project by project.
Interconnect characterization
S-parameter measurement and analysis of connectors, cable assemblies and passive channels: insertion and return loss, crosstalk, mixed-mode data, and TDR impedance. You receive data files and written findings.
Channel modeling and data analysis
Ansys HFSS models of channels, vias and transitions, plus Python processing of Touchstone data, including channels up to 112G PAM4. You receive model files, scripts on request, and a report.
Test procedures and training
Repeatable lab procedures written from industry specifications, and training on VNA calibration and measurement consistency.
The founder does the core measurement and analysis personally. When a project needs expertise outside that core, we bring in subcontractors or partners and say so in the proposal.
Tools: Ansys HFSS · Python · VNA and PXIe test systems · BERT scopes and oscilloscopes.
