Lost Connectivity = Lost Revenue: The Crucial Role of Wireless WAN Failover in Network Resilience

In an age where everything is online, can businesses afford to lose connectivity even for a minute? Whether it’s the unpredictability of brownouts or the severity of complete network outages, the toll on organizations is significant in terms of time, resources, and income. Research from Netrounds revealed that many companies need to pay more attention to the costs associated with these disruptions. According to their research, IT teams failed to detect over 60% of brownouts,— meaning customers and employees identified nearly 40% of the issues, while 14% went unnoticed. Companies surveyed reported an average annual loss of nearly $600k from loss of productivity to mitigating the loss of connectivity. With transactions, communications, and operations all dependent on the internet, a minute’s downtime is a luxury you can’t afford.  

Maintaining uninterrupted internet connectivity is not just a luxury but a necessity for businesses in today’s digitally-driven age. Think about it: a minor disruption can lead to massive financial losses and compromised data. Enter Wireless WAN failover—a game-changer that ensures network operations remain resilient, even when primary connections stumble. Let’s deep-dive into the world of WAN failover, its automated mechanisms, the unique advantages of 5G/LTE failover, and the ever-growing importance of wireless failover in today’s networks. 

Understanding WAN Failover 

Network performance issues can come in various forms. These might be due to cabling mishaps, mistakes in system configuration, traffic logjams, power outages, problems in the ISP network, or even network loops that can create chaos. 

Let’s paint a picture. Envision a major online sales event, perhaps something akin to Black Friday. The website is bustling with traffic, carts are filling up, and transactions are happening every second. Now, if the primary internet connection drops even for a minute, the business could suffer immense losses financially and in terms of customer trust. That’s where failover steps in, acting as a safety net, ensuring that operations continue smoothly, even when the primary connection is compromised. 

The Magic of Automatic Failover 

Ever noticed how some businesses keep ticking even when there’s a major service disruption? That’s automatic failover at work, ensuring consistent operations.  

Understanding Automatic Failover: 

  • Detection Mechanisms: Contemporary systems are vigilant round-the-clock. They are equipped to assess the health of their connections. Tools, like ping tests, regularly send signals to distant hosts to ensure connectivity remains constant. It’s like a heartbeat monitor for the internet. 
  • The Failover Process: Here’s what happens behind the scenes: the moment a connection issue is sensed, the traffic, almost instantaneously, is redirected to a backup connection. All network parameters, such as gateway addressing and DHCP table, are instantly shared so that the network can continue operating as if nothing has changed. It’s a transition so swift that the end-user rarely notices. 
  • Automatic vs Manual Failover: Instead of a system instantaneously switching to a backup during an issue, a person must first detect the problem and then manually switch to another connection. The latter can be laden with delays and errors. This is why automatic failover, with its speed and precision, is a favorite for businesses. It promises minimal interruption, ensuring operations continue almost as if nothing happened. 

Why is Failover Essential? 

Failover is the guardian of mission-critical systems. These are systems that businesses rely on to ensure they can operate seamlessly and meet their customers’ needs. 

However, there’s a caveat. The backup system that takes over when the primary fails must be equally resilient. It can’t be the weak link; that would defeat its purpose. 

The Top Benefits of a Reliable Failover Solution: 

  • Reduced Downtime: In the face of technical glitches, businesses can guarantee seamless customer experiences and substantially reduce downtime, allowing operations to persist unhindered even if the primary system faces challenges or maintenance.  
  • Mitigated Risks: Downtime can be expensive. Beyond the obvious financial implications, there’s the risk of data loss, reduced productivity, and potential harm to brand reputation. Failover keeps these risks at bay. 

Today’s IT networks are complex, from traditional on-site infrastructures to diverse combinations of private, hybrid, and public cloud setups. Despite the complexities of coordinating failover across diverse platforms, guaranteeing business resilience and uninterrupted operations makes it a worthy investment.  

A Closer Look at Cellular 

In today’s connected world, cellular networks blanket almost every corner, making their role as backup channels a sensible and readily available option to nearly every network. 

Maximizing Resilience: 

Modern technologies like LTE and 5G diversify the network, reducing failure points and offering cost-effective backup solutions. These wireless links, tailored to a company’s budget and needs, can support mission-critical data or an entire branch’s network load. David Everingham, CTO of Ericsson Canada, highlights that enterprises value wireless offers enterprises “the agility, flexibility, security and scale they need to drive real transformation and innovation in their businesses.” Wireless connections enable remote management of branch equipment, minimizing on-site interventions. Their evolving role is pivotal in shaping today’s business operations and responses to challenges. 

Cellular Networks and WAN Systems: 

Cellular networks aren’t just stand-alone entities; they’re interwoven into WAN systems. In simpler terms, when the primary channel of a WAN system falters, the cellular network seamlessly steps up as the backup. 

  • Efficiency and Speed: Gone are the days when cellular networks lagged behind in terms of speed. With the rise of 5G, they not only match but, in some areas, even surpass the speeds of traditional broadband. This makes them an effective choice for failover. 
  • Signal Strength: Signal strength can vary. However, concerns with signal strength can be readily addressed using a range of advanced antennas. Depending on the specific requirement and location, both indoor and outdoor antennas can be employed to optimize signal reception. Additionally, the topography of 5G infrastructure is growing denser, making coverage more widespread and consistent. 
  • Data Caps and Cost: Unlimited data plans are not yet ubiquitous. There are data caps to consider, which can restrict large data transfers and costs that might stretch a company’s budget. While it’s true that some cellular plans come with data restrictions, this is where partnering with a global Mobile Virtual Network Operator (MVNO) becomes pivotal. Bespoke plans address both data cap concerns and ensure cost-effectiveness. 
  • Installation Expertise: Partnering with a managed service provider can quickly alleviate any concerns regarding setup and integration. They offer the expertise to deploy the entire package seamlessly, ensuring your organization can make the most of wireless backup without the hassles. 

Wired vs. Wireless 

While wired solutions like dedicated internet access or MPLS can offer a degree of stability and increased internet availability, they come with hefty price tags. Moreover, they lack the adaptability that wireless solutions bring to the table—another consideration: physical vulnerabilities. Wired redundancies might succumb to the same physical damage as the primary connection, rendering them ineffective when needed the most. 

As the business world becomes more interconnected and dynamic, moving towards wireless solutions isn’t just a good idea—it’s an essential strategy for sustainable growth and resilience.
