Enterprise Networking Solutions
Secure, high-performance connectivity that scales
Modern businesses rely on secure, high-performance connectivity. We design and implement intelligent network architectures that maximize performance across offices, branches, cloud, and remote workforces.
What we deliver
Most network problems that get reported as "the internet is slow" are not bandwidth problems. They are a saturated uplink, a duplex mismatch, a broadcast domain that has grown too large, or a wireless design that was drawn on a floor plan instead of surveyed on site.
We design networks around traffic patterns and physical reality: where the users sit, what the walls are made of, which applications are latency-sensitive, and where the failure domains should be drawn. Segmentation, resilience and capacity are decided at design stage, because retrofitting them into a flat network is expensive.
Deployment includes configuration standards applied consistently across the estate, monitoring so degradation is visible before users report it, and documentation that maps every VLAN, subnet, SSID and uplink to a purpose.
Scope
A typical networking engagement covers:
- Enterprise LAN / WAN solutions
- Wireless network infrastructure
- Managed switching solutions
- Firewall & VPN solutions
- SD-WAN solutions
- Remote connectivity solutions
- Network monitoring systems
- Network optimization services
How we deliver
From site walk to handover.
- 01 SurveySite walk, existing topology capture, and for wireless a predictive or on-site RF survey against real construction materials.
- 02 ArchitectSegmentation, addressing, routing, resilience and wireless channel plan documented before any hardware is ordered.
- 03 DeployStaged rollout with standardised configuration, tested failover, and cutover scheduled outside business hours.
- 04 MonitorAlerting on uplink saturation, AP health and device availability, tuned to reduce noise rather than generate it.
Standards
Built to standards your auditors check.
- Wi-Fi 6 / 802.11ax — current mainstream wireless standard; improves behaviour in dense client environments rather than headline speed.
- VLAN segmentation — separating voice, data, guest, CCTV and building systems limits both congestion and lateral movement.
- Documented addressing — every subnet, VLAN ID and SSID mapped to a purpose and issued at handover.
Why dexline for networking
- Wireless is surveyed, not guessed.
Coverage predicted from a drawing rarely survives contact with concrete, glass partitions and shelving. We validate on site.
- Segmentation designed in.
Voice, CCTV, guest and building systems are separated from day one, which is far cheaper than retrofitting it after an incident.
- Consistent configuration.
Standardised templates across switches and access points, so troubleshooting does not depend on who built which closet.
- Cutovers are reversible.
Migration windows have a defined rollback point before we start, not after something goes wrong.
FAQ
How many access points does our office need?
Coverage is driven by client density and construction materials more than floor area. An open-plan office with plasterboard partitions needs far fewer APs than the same square metres divided into concrete-walled rooms, and a high-density space such as a training room or auditorium may need several APs where coverage alone would suggest one. We size from a survey rather than a per-square-metre rule of thumb.
Do we need SD-WAN?
SD-WAN earns its cost when you have multiple sites, more than one internet circuit per site, or applications that need to fail over between links without dropping sessions. For a single office on a single circuit it usually adds licensing and complexity without a matching benefit. We are happy to say when it is not warranted.
Can you work with our existing switches and firewalls?
Usually yes, provided they are still receiving firmware and security updates from the vendor. Equipment past end-of-support is a different matter: it cannot be patched, so it becomes a security exposure regardless of whether it still passes traffic. We flag anything in that category explicitly.
Will the network need downtime during the upgrade?
Some, but it is planned and bounded. Core switching and routing changes are scheduled outside business hours. Access-layer and wireless work can often proceed floor by floor with no disruption to the rest of the site. We agree windows before starting and define the rollback point for each.
Should CCTV run on the same network as our office data?
It can share physical infrastructure but should be logically separated onto its own VLAN. Cameras generate sustained multicast and unicast streams that will contend with business traffic, and surveillance devices are a common weak point for network intrusion. Separation addresses both concerns at effectively no extra hardware cost.
