Network Infrastructure

Pages / Network Infrastructure – OLD WORKING

The Network Is the Foundation. We Build It to Last.

Every application, communication system, and security control in your organisation depends on the network beneath it. Commtel’s network infrastructure practice designs and delivers enterprise connectivity built for performance, resilience, and the demands of modern digital operations.

When the network underperforms, through poor design, insufficient capacity, or inadequate security controls, every system built on top of it is affected. The cost of network problems rarely stays contained to the network team.

Commtel has designed and deployed network infrastructure across enterprise environments for 25 years. Our engagements range from greenfield campus network deployments to the rationalisation of complex multi-site estates that have accumulated years of technical debt. In every case, the objective is a network that is secure, observable, manageable, and built to support the applications and users that depend on it.

Service Areas

LAN and Campus Network Design

Commtel designs campus and building LAN environments that balance performance, redundancy, and manageability, with security controls embedded at the architecture level rather than layered on afterwards.

What this covers

  • Layer 2/3 switching architecture design and deployment
  • Network segmentation and VLAN design
  • Redundancy and high-availability configuration
  • Network access control (NAC)
  • Multi-site LAN standardisation
  • Vendor platforms: Cisco, Juniper, HPE Aruba, and others

WAN and SD-WAN

As enterprise workloads distribute across multiple sites, cloud environments, and remote locations, the wide-area network must evolve accordingly. Commtel’s WAN practice designs connectivity architectures that provide reliable, secure access to applications regardless of where users or workloads reside.

What this covers

  • WAN architecture design and optimisation
  • SD-WAN platform selection, design, and deployment
  • MPLS rationalisation and hybrid WAN strategies
  • ISP management and redundancy planning
  • Quality of service (QoS) design for voice and video workloads

Enterprise Wireless

Wireless has become as critical as wired connectivity across enterprise environments. Commtel designs and deploys wireless networks that deliver consistent, high-density coverage across campuses, office buildings, warehouses, hospitality properties, and outdoor environments.

Commtel’s wireless practice includes experience across Pakistan’s hospitality sector, including the enterprise Wi-Fi deployment at Serena Hotels, Hunza.

What this covers

  • Wireless site survey and RF planning
  • High-density Wi-Fi design and deployment
  • Wireless security (WPA3, 802.1X, rogue AP detection)
  • Guest and IoT network segmentation
  • Centralised wireless management and monitoring
  • Vendor platforms: Cisco, HPE Aruba, Ruckus, and others

Network Security

Network security is a design principle, not an addition made after the fact. Commtel’s network security practice integrates firewall policy, traffic inspection, segmentation, and access control into the network architecture from the ground up.

What this covers

  • Next-generation firewall (NGFW) design and deployment
  • Network segmentation and micro-segmentation
  • Intrusion detection and prevention (IDS/IPS)
  • Secure Access Service Edge (SASE) architecture
  • Network traffic analysis and anomaly detection
  • Firewall policy review and optimisation

Network Operations and Management

Deploying infrastructure is one discipline. Operating it to a consistent standard over time requires dedicated process, tooling, and expertise. Commtel’s network operations capability provides the resources to maintain performance, respond to incidents, and plan for capacity growth.

What this covers

  • Network monitoring and observability
  • Configuration management and change control
  • Incident response and fault management
  • Capacity planning and performance reporting
  • Managed network services

Why Commtel for Network Infrastructure

Security-integrated design

Commtel’s security and network practices work together from the outset. Every network we design accounts for threat detection, access control, and traffic inspection as part of the initial architecture.

25 years of enterprise deployment

Our network engineers have designed and deployed infrastructure across banking, manufacturing, government, hospitality, and telecommunications environments. That breadth of experience informs every new engagement.

Vendor-neutral architecture

We maintain certifications and partnerships across the leading network infrastructure vendors. Our architects select platforms based on your requirements, including performance, budget, existing investments, and operational preference.
