7 Critical Things to Consider When Updating and Modernizing IT Networks

Why Upgrading Your IT Network Is Essential
Aging networking infrastructure leads to security vulnerabilities, reduced efficiency, and higher operational costs. Outdated routers, switches, and cabling can't keep up with modern connectivity demands, limiting bandwidth and exposing systems to cyber threats. Upgrading ensures faster speeds, better reliability, and the ability to scale with future technology needs.
1) Future-Proofing with Wi-Fi 6E and Beyond
Wi-Fi 6E extends the capabilities of Wi-Fi 6 by utilizing the 6 GHz spectrum, reducing congestion and improving speeds. For businesses with high-density wireless demands, upgrading to Wi-Fi 6E or planning for Wi-Fi 7 is essential to maintain seamless connectivity and handle bandwidth-heavy applications such as AR/VR and 4K video conferencing.
2) Implementing 5G Failover for Network Redundancy
Unplanned downtime is costly, making network redundancy a top priority. A 5G failover solution provides high-speed backup connectivity when primary wired connections fail. Modern LTE/5G-enabled routers can automatically switch to cellular networks, ensuring business continuity, reduced latency, and consistent uptime for critical operations.
3) Upgrading Network Gateways for Enhanced Security
Legacy network gateways can become security liabilities. Modern gateways integrate advanced firewall capabilities, AI-driven threat detection, and Zero Trust Network Access (ZTNA) to mitigate risks. Investing in cloud-managed gateways allows for centralized security policy enforcement and real-time monitoring to protect against evolving cyber threats.
4) Optimizing Structured Cabling and Fiber Backbones for High-Speed Data Transfer
Cat6A and Cat8 cabling provide the necessary bandwidth for 10G and even 40G Ethernet networks. Structured cabling upgrades are critical for organizations relying on low-latency connections, IoT devices, and PoE (Power over Ethernet) systems. Additionally, deploying fiber optic backbones ensures ultra-fast data transfer between network switches, data centers, and key infrastructure points, reducing bottlenecks and supporting higher data loads. Proper cable management and shielding also reduce interference and ensure long-term network performance.
5) Enhancing Wireless Coverage with DAS and Small Cells
Distributed Antenna Systems (DAS) and small cell networks improve indoor wireless coverage, particularly in large office spaces, warehouses, and retail environments. DAS solutions ensure seamless cellular and Wi-Fi connectivity, reducing dead zones and enhancing mobile device performance within the enterprise network.
6) Cloud-Managed Network Infrastructure for Remote Administration
IT teams need real-time visibility and remote control over networking hardware. Cloud-managed networking solutions allow administrators to configure routers, access points, and switches from a centralized dashboard. Features such as AI-driven network optimization, automatic firmware updates, and remote troubleshooting streamline IT operations.
7) Implementing SD-WAN for Efficient Multi-Site Connectivity
For businesses with multiple locations, Software-Defined WAN (SD-WAN) improves network performance and security by dynamically routing traffic over the best available connections. SD-WAN solutions enhance cloud application performance, enable secure site-to-site connectivity, and reduce dependency on expensive MPLS circuits.
