The network will often provide clear signals that a refresh is necessary.
Ideally, network hardware should be refreshed every three to five years. However, “ideal” can seem like an unnecessary headache for small to midsize enterprises (SMEs). A major network overhaul is expensive, time-consuming and disruptive, particularly for SMEs that lack in-house IT expertise and resources. Five years can stretch into six, seven or more.
There comes a time, however, when sluggish performance causes frequent user complaints. Security vulnerabilities outpace IT’s ability to patch them. Worse, legacy hardware reaches end-of-support, creating the risk of extended downtime.
When these warning signs pop up, SMEs should prioritize a network upgrade before equipment breaks down. A phased approach, the right equipment and the right expertise can ensure that the upgrade goes smoothly, stays within budget and minimizes disruption.
Recognizing the Warning Signs
The network edge and the network core have different signals that an upgrade is necessary. The network edge is where users and devices connect. The network core handles high-volume routing.
User complaints are often a good indicator that the network edge is lagging behind. When the number of devices exceeds the network’s capacity, performance slows and real-time applications struggle. Legacy wiring or switches cannot deliver the Power over Ethernet (PoE) needed for Wi-Fi 6E/7 or modern IoT devices.
An aging network core causes more serious problems. Switches cannot process aggregated data from edge devices fast enough, causing unacceptable latency. High packet loss and frequent buffering occur even during non-peak hours. The core is too rigid to handle automation or cloud-native migration shifts.
Upgrading all this equipment at once would be expensive and cause an unacceptable amount of disruption. A phased roadmap isolates the core backbone first to prevent systemic failure, then scales outward to the edge. This strategy minimizes downtime and spreads out capital expenditures over time.
A Phased Approach to Network Upgrades
The goal of the first phase is to secure the foundation and address immediate operational risks. IT should first inventory all hardware, software licenses and end-of-life (EOL) dates. The top priority should be to replace failing central switches and firewalls to eliminate major bottlenecks. Software-defined routing at the core can optimize multi-location and cloud traffic.
In Phase 2, the goal is to connect the stabilized core to the end-user network. IT should replace mid-tier switches linking the core to the edge to support higher bandwidth. Deploying secure access service edge architecture enables uniform, cloud-based security rules. It’s also critical to segment the network to contain a potential breach.
The final phase is designed to improve the end-user experience and support high-density device environments. IT should deploy Wi-Fi 6E or Wi-Fi 7 hardware in high-traffic zones first. It’s also a good idea to install newer PoE switches to power advanced cameras and IoT gear. AI-driven monitoring software can automatically troubleshoot edge connection issues.
Choosing The Right Solutions
In many SMEs, the network evolved to include a patchwork of different vendors’ devices. Equipment may have been purchased based on cost or the expertise of a given network administrator. A phased upgrade offers an opportunity to rethink the network architecture.
RUCKUS is an exceptional choice because its patented hardware engineering solves high-density traffic bottlenecks while slashing overall infrastructure costs. Where other brands require organizations to buy more hardware to fix dead zones, RUCKUS relies on smarter physics and AI-powered management.
Standard access points (APs) blast Wi-Fi omnidirectionally, causing massive self-interference in high-density environments. RUCKUS BeamFlex+ technology uses an internal smart antenna array to reconfigure signal patterns in real time. It steers focused beams at moving client devices while blocking background noise.
For the network core and distribution layers, the RUCKUS ICX Switch Portfolio provides heavy-duty bandwidth handling and can readily scale to meet growing requirements. The core switches, edge routers and wireless APs can all be managed through the RUCKUS One cloud-native dashboard.
Getting the Right Expertise
Upgrading a core and edge network requires specialized expertise that internal IT teams rarely have. A managed services provider (MSP) mitigates the risk of a network migration by acting as an outsourced engineering and operations team.
A qualified MSP eliminates the guesswork and over-purchasing that often happens during standalone enterprise upgrades. MSPs use radio frequency heat-mapping tools to design the AP layout, ensuring zero dead zones before buying hardware. The MSP will audit the existing cabling to ensure that it can handle the PoE demands of the new edge switches.
An internal team cutting over a network core often faces prolonged outages. MSPs use redundant engineering practices to keep the business online. MSPs can pre-configure and test switches and APs in their own labs. Devices arrive onsite as a “plug-and-play” deployment.
MSP cutovers are scheduled during off-peak hours, backed by a dedicated team of engineers ready to handle unexpected routing conflicts. Every phase of the deployment includes a rollback plan, ensuring that the legacy network can be restored if a critical system fails to connect.
Predictable Costs and Financial Flexibility
Network upgrades demand high upfront capital expenditures. A qualified MSP can shift this burden into a predictable operating expense. An MSP that partners with leading vendors such as RUCKUS can often bundle hardware, licensing, installation and ongoing support into a flat monthly subscription. The MSP tracks device ages, automatically staging the next hardware refresh in three to five years.
Once the hardware is in place, the MSP acts as a 24x7 network operations center. The MSP uses advanced tools to detect and resolve issues before users notice a slowdown. MSPs also handle software and firmware updates, fully testing each patch to ensure that security gaps are closed without crashing the network.
Organizations should pay attention when the network signals that an upgraded is needed. Rather than postponing the inevitable, organizations should plan a phased upgrade using the right equipment and expertise.
