Connectivity Standards Overview
Reference overview of enterprise network connectivity options, comparing characteristics, use cases, and deployment considerations for Canadian infrastructure planning.

Enterprise Connectivity Landscape
Enterprise network connectivity spans from the physical campus LAN through the WAN to cloud-hosted services. Modern smart network infrastructure combines multiple connectivity technologies — wired Ethernet for fixed workstations and network equipment, Wi-Fi for mobile devices and flexible workspaces, and WAN technologies for site-to-site and internet connectivity. Each layer requires distinct planning, procurement, and operational approaches.
Canadian enterprise environments present specific characteristics: large geographic distances between sites, established incumbent telecommunications providers offering managed WAN services, regulatory frameworks governing spectrum use and telecommunications infrastructure, and a mix of modern cloud-first architectures alongside legacy systems in regulated industries including finance, healthcare, and utilities.
Wired Standards
Wired Ethernet remains the foundation of enterprise campus network infrastructure. The dominant standard for access layer connections is 1 Gigabit Ethernet (1GbE) to workstations, with 10GbE increasingly common for server connections and uplinks. Distribution and core switches typically operate at 10, 25, or 100 Gigabit speeds depending on network scale.
Power over Ethernet (PoE and PoE+) enables delivery of electrical power to network-connected devices — IP phones, wireless access points, security cameras, and IoT sensors — over the same copper cabling used for data. PoE planning requires calculating total power budget for all connected devices and sizing switches with adequate power supply capacity, not only port count.

Wireless Standards
Wi-Fi 6 (802.11ax) and Wi-Fi 6E are the current enterprise standards for high-density wireless coverage. Wi-Fi 6E extends into the 6 GHz band, providing additional spectrum for high-bandwidth applications and reducing interference in congested environments. Wi-Fi 6E is particularly relevant for campuses with high device density — open-plan offices, manufacturing floors, warehouses, and public venues.
Private 5G networks offer an alternative for organizations requiring outdoor coverage, extreme mobility scenarios, or very low latency for industrial IoT applications. Private 5G deployments require spectrum licensing in Canada — through Innovation, Science and Economic Development Canada (ISED) — and represent significantly higher deployment complexity and cost than enterprise Wi-Fi for typical office environments.

WAN Connectivity
Enterprise WAN connectivity connects geographically distributed sites. Available options for Canadian organizations include MPLS (Multiprotocol Label Switching) services from incumbent carriers, broadband internet with software-defined WAN (SD-WAN) overlay, dedicated fibre services for high-bandwidth requirements, and LTE/5G cellular backup for resilience.
SD-WAN has become the dominant approach for new WAN deployments, providing application-aware traffic routing, encrypted connectivity over any underlying transport, and centralized policy management across all sites. SD-WAN reduces dependence on expensive MPLS circuits while providing equivalent or better application performance through intelligent path selection.
Standard Selection Criteria
Selecting connectivity standards for an infrastructure deployment requires assessing requirements across several dimensions: throughput requirements per device and aggregate, latency requirements for latency-sensitive applications, coverage area and building characteristics, device density and types, mobility requirements, existing infrastructure investment, operational team capabilities, and total cost of ownership over a five to seven year planning horizon.
| Technology | Typical Use Case | Throughput | Deployment Cost |
|---|---|---|---|
| Gigabit Ethernet | Wired workstations, servers | 1 Gbps | Low (existing cable) |
| 10 Gigabit Ethernet | Server connections, uplinks | 10 Gbps | Medium |
| Wi-Fi 6 (802.11ax) | Enterprise wireless | Up to 9.6 Gbps (theoretical) | Medium |
| Wi-Fi 6E | High-density wireless | Up to 9.6 Gbps, 6 GHz band | Medium-High |
| Private 5G | Industrial IoT, outdoor coverage | Up to 20 Gbps (theoretical) | High |
| SD-WAN | Multi-site WAN, internet breakout | Varies by underlying circuit | Medium (software) |
Canadian Deployment Context
Network infrastructure deployments in Canada operate within a regulatory framework administered by ISED, the Canadian Radio-television and Telecommunications Commission (CRTC), and applicable provincial authorities. Wireless deployments require compliance with radio frequency emission standards. Telecommunications infrastructure in buildings may require coordination with property management and local building codes. Large-scale wireless spectrum deployments require spectrum licensing.
Canadian internet exchange points (IXPs) in Toronto, Montreal, Vancouver, and Calgary provide low-latency interconnection paths for organizations with significant internet traffic. Proximity to IXPs is a relevant consideration for data centre and colocation facility selection.
