Warehouse Wi-Fi FAQ: What are the Most Common ‘Pain Points’ with Warehouse Networks?

Warehouses are fast-paced environments where many pressure points in supply chains converge. When these pressure points are factored into space design and management, the capacity to gain and retain a competitive edge is there for the taking. This special management increasingly involves high-performance networking to underpin an increasingly automated warehouse with Wi-Fi-first devices – from sensors to driverless tech.

So what are the most common ‘pain points’ we see when it comes to warehouse Wi-Fi? There’s a long list, including slow picking and inaccurate data, but one thing they all have in common is their net result: an inefficient warehouse.

Warehouses are difficult environments for high-performance networking, and the odds are stacked (or racked!) against you. But so many of these pain points are caused by avoidable mistakes.
Below we delve into the problems warehouse managers and their IT teams report the most often, exposing their knock-on effect as well as the causes.

1. Inefficient picking

2. Inaccurate inventory tracking due to packet loss

3. No real-time communications between staff on order updates, schedules, safety alerts, etc.

4. Equipment downtime, especially Wi-Fi-first devices (which are increasing)

5. Errors in quality control

6. Risk of data breaches through unauthorised access, malware attacks, and more during downtime or at weak points in the network architecture

These issues all ultimately converge to cause delayed dispatching, revenue loss through data inaccuracies, higher shrinkage rates, and customer dissatisfaction.

Longer-term, slow, unscalable or patchy networks cause adopted technologies reliant on high-performance connectivity to ‘fail’. This has a huge knock-on effect on the ROI of investments like sensors, driverless tech, and expensive warehouse management systems.

So what causes these issues?

1. Lack of scalable bandwidth

As warehouse technology rises, bandwidth is a huge factor that businesses must consider – it underpins productivity in a digital age, and waiting until problems arise means you’re already feeling the financial impact

2. Channel congestion

This is largely a removed issue for warehouses who have shifted to Wi-Fi 6, but for many this is becoming a challenge for IT functions, reducing speed and capacity, as well as causing bottlenecks – hardly ideal for WMS

3. APs not designed for challenging environments

Warehouses are tough environments where your tech needs to be even tougher. Outdoor connectivity for loading bays, dust, cold, heat… all these factors should inform choices during network design

4. APs with limited throughput capacity

Again, individually small components of your network can determine overall network performance, and older access points are often unable to deliver the throughput needed for today’s warehouses and their connected devices – edge to core

5. Black spots in coverage

Poor network design resulting in gaps in coverage that wreak havoc on picking. We’ve seen cases where racking areas can’t be used due to the inability to pick stock in those zones

6. Interference from electronics, metals, racking, building structures

This is a huge issue in warehousing, with so many objects and materials – static and moving – that can interrupt a consistent signal. This is especially common where networks were planned during construction, or off-plan.

7. Wrong AP antennae

Warehouses are unique environments and the traditional ‘donut’ signal won’t provide the coverage you need. Specialist access points are required with these spaces in mind

8. Wrong AP placement

Poorly placed APs can lead so many warehouses to do entirely the wrong thing – add more! Just take a look at our article on ‘quick warehouse Wi-Fi fixes that don’t work’!

7. Poor configuration

Managing wireless networks throughout supply chains requires a seamless configuration, since supply chains are themselves aiming on seamlessness. Poorly matched security protocols, channel settings, mismatched power levels, and many other mistakes are easy ways to ensure your supply chain has too many sticky patches to be efficient.

It’s no secret – warehouses are more challenging than other environments when it comes to designing, installing and maintaining high performance connectivity, but we see a wealth of industry experience around us that is helping transform these spaces just by gaining a stronger understanding of how they flow.

What are your pain points when it comes to connectivity in your warehouse?

With the increasing reliance of warehouses on technology, it is no surprise that as IT advances, the opportunity to close gaps in efficiency and reduce the impact of errors is one that the most successful warehouses are taking advantage of. High performance networking – and in particular wireless networking – underpins much of this emerging technology. Below we examine why superior Wi-Fi in warehouses is vital if businesses are to gain a competitive edge with today’s evolving supply chain.

Faster connectivity:

Next-gen networking technologies provide faster and more reliable connectivity within the warehouse environment. This enables real-time communication and data exchange between various systems, such as inventory management, warehouse management, and order fulfilment systems. With improved connectivity, warehouse operations can be streamlined, eliminating connectivity issues and enabling uninterrupted operations, improving efficiency.

Improved mobility:

It’s not all about speed. Next-gen networking technologies, such as Wi-Fi 6, offer improved coverage, enabling wireless connectivity throughout the warehouse. This is particularly important for the rising number of mobile devices used by warehouse staff, such as handheld scanners, tablets, and wearable devices, to say nothing of emerging tech yet to become widely adopted. With reliable wireless connectivity, employees can access real-time information, update inventory records, and communicate with colleagues from anywhere within the warehouse, improving productivity, responsiveness and the accuracy of inventory management and tracking.

Supporting successful warehouse automation:

Linked to both speed and coverage, superior Wi-Fi is crucial for supporting warehouse automation initiatives which are seeing rapid adoption due to their ability to deliver and maintain a competitive edge to businesses. Automated systems, such as robotic picking systems or autonomous guided vehicles (AGVs), rely on Wi-Fi connectivity to communicate with the warehouse management system (WMS) and coordinate tasks efficiently. A reliable and high-speed Wi-Fi network with 100% coverage delivers ROI on the cost of having implemented automated processes and devices.

Supporting IoT integration for greater awareness:

Similarly to larger automated machines and tools, warehouses are increasingly adopting smaller IoT devices such as sensors to automate processes, track inventory, and monitor equipment. Next-gen networking infrastructure supports the seamless integration of these IoT devices, allowing them to communicate and share data efficiently. This integration enables real-time monitoring, predictive maintenance, and optimization of warehouse operations, leading to reduced downtime and cost savings on building and contents maintenance. Find out more about designing wireless networks with IoT in mind.

Cloud integration and data management:

Next-gen networking facilitates seamless integration with rapidly expanding cloud-based services and platforms which we are already seeing become a pillar of networks. This easy integration enables warehouses to leverage cloud computing power and storage for data-intensive applications, such as data analytics, machine learning, and artificial intelligence. By leveraging cloud services, warehouses can optimise their data management processes, gain actionable insights, and make data-driven decisions to improve operational efficiency and inventory management – all without needing additional data storage.

Security and data protection:

Next-gen networking technologies incorporate advanced security features, including robust encryption, authentication mechanisms, and network segmentation. In a warehouse setting, where sensitive data such as inventory information and customer details are stored and transmitted, ensuring the security and protection of data is of paramount importance. This is only becoming more critical as the number of devices (including those that are cloud-first) grows, permitting more breach points for cyber-attacks. Next-gen networking provides the foundation for implementing strong security measures to safeguard critical information from unauthorised access and potential cyber threats.

Voice and video communication:

In some warehouse operations, voice communication is critical for coordinating tasks, providing instructions, or addressing safety concerns. With superior Wi-Fi, voice-over-Wi-Fi (VoWi-Fi) solutions can be implemented, enabling employees to use wireless headsets for real-time voice communication. Additionally, Wi-Fi can support video communication for remote collaboration, troubleshooting, or training purposes, improving communication effectiveness and reducing the need for physical presence.


As technology continues to advance, warehouse businesses need to be prepared for future requirements. Superior Wi-Fi provides the foundation for adopting emerging technologies, such as augmented reality (AR) or virtual reality (VR) for warehouse training, or advanced analytics for operational optimisation. By investing in a robust Wi-Fi infrastructure, warehouse businesses can adapt to evolving technology trends and remain competitive in a rapidly changing industry.

Rising customer expectations, an ‘on-demand’ supply chain, the complexity of global logistics, the move towards customisation – these and many other challenges are forcing players in manufacturing and supply chains to transform their operations in order to retain a competitive edge.

Both unearthing and implementing these transformational changes – however – requires a huge amount of digging into productivity, efficiency, and where gaps can be closed through innovation. To add to the size and scope of this task, as technology advances, the rate at which these gaps become evident increases; businesses slow to identify them are left further behind, faster.

Tackling these major challenges demands a shift in the way efficiency and productivity are handled, namely moving away from human monitoring, analysis and review towards automated systems that take advantage of machine learning, AI and cloud-based management.

Enter IoT and its capacity to help find productivity gaps and close them more accurately, efficiently, and affordably than humans ever can. The data generated by these devices provides organisations with real-time, data-driven insights that can have automated corrective actions, and embed an agile approach to change and transformation within the business.

McKinsey research estimates that by 2025, IoT devices and their application could save businesses over £350 billion per year in operational costs.

Benefits of Adopting IoT & Automated Monitoring of Efficiency

Reducing operational costs

Optimising how products are made, moved and managed throughout your supply chain carries huge cost savings through:

Health & safety

Your workforce is one of – if not the most – expensive cost to your business. IoT can help increase its profitability through:

Improved Production

Improving how each element of your production line performs means faster production times and better output as a whole, primarily through:

Realising the Potential of IoT in Warehouses & Avoiding Failed Adoptions

The benefits of IoT are clear, however successful deployments are based on more than just a plug and play approach, and many organisations who fail to adequately plan see their investment fall flat.

So what are the main reasons IoT adoption in warehouse environments fails? An initial factor that can lead to failure is a human one. A business culture that is not ready for a data-driven approach to strategy can cause serious issues, from resistance to the change to not having the adequate skillset available, either in house or external. This can be a challenge to overcome post-deployment.

The simplest and most easily remedied reasons for failure, however, are IT ones, including:

There’s no doubt that adopting a data-driven business strategy with IoT at the centre puts pressure on your IT infrastructure, from a rising number of inter-connected devices on the edge, all independently aggregating and analysing data, to consistently higher traffic, blurred network edges and higher security risks.

Networks that cannot provide the necessary connectivity foundations for IoT will prevent your organisation from realising the value of IoT – both it’s current and exponentially bigger future potential.

This is where next-gen networks, primarily Wi-Fi 6 and cloud-based networks excel. Wi-Fi 6 delivers 160 MHz of bandwidth, data rates of 10Gbps, and operates at 5 GHz, giving superior performance that’s quite literally made for IoT, with faster throughput, reliable and robust connectivity, significantly less congestion and reduced power consumption. Moving to a cloud-based network removes limits on your IT infrastructure, making it truly scalable, offering easy deployment with zero-touch-provisioning, and giving total control of every device from anywhere, any time. Cloud-based networks are ideal for multi-site businesses where having locally managed networks are becoming increasingly complex and disjointed – for example supply chains, manufacturing and logistics. In short, cloud-based networks mean you can build, monitor, manage and scale your smart spaces faster, easier, and with better outcomes.

Any network which looks to take advantage of constantly evolving tech such as IoT needs to be designed with the future in mind – both the future of your business and the future tech it will look to adopt.

Warehouses are complex environments for WiFi. Users and devices are constantly moving from place to place, the signal is attenuated by racking, and there is a large area to cover. As a result, many systems that would perhaps work well in a simpler environment (such as an office) are not transferable to the warehouse.

When issues inevitably arise, it is understandably often a kneejerk reaction to make quick changes to try and mitigate the problems caused by a struggling network. These include:

Add more access points

This may well be the solution to your problem. Still, it needs to be managed carefully to ensure we’re covering the desired areas without causing interference to the rest of the network.

Install warehouse WiFi extenders

This technology has many names (warehouse WiFi boosters, repeaters), but all do the same thing – extend your Wi-Fi coverage; however, it causes additional jitter, latency, delay, reduces overall throughput and increases interference. These types of solutions should be avoided. Trust us, there are better options.


Meshing can be used to solve coverage and can work well under certain stances. However, when you try to mesh multiple APs, place those APs too far away from each other or connect numerous devices, you can quickly run into issues. Meshing can work well in homes or small offices but it doesn’t support the capacity or throughput needed by most warehouses.

Turn up the power

Increasing the transmit power of your access points may seem like an easy way to improve coverage. However, Wi-Fi is a two-way conversation, and your devices also need to talk louder to send that signal back. In most battery-powered devices, this is not an option.

Use wider channel widths

Using wider channels enables higher data rates, making it appealing for many users. However, there is a limited amount of spectrum to use, and as a result, wider channels can often cause interference.

Usually, these ‘solutions’ are akin to placing a plaster on an open-heart wound, and in some cases, may create more problems than they solve! You’re then left with a more convoluted IT infrastructure that’s harder to monitor, harder to manage, and with more things to break down or go wrong. In short, you’ve compromised the integrity of your network so that it is unlikely to offer even, reliable performance in all areas you need it to.

At Redway Networks, we take a different approach to designing networks. Every warehouse is different, and as a result, we tailor each design to our customer’s needs. We consider the layout of the building, the materials inside, what devices are in use, how many and what future plans the business has for Wi-Fi usage. To deliver a successful design that will last for years, we utilise industry-leading tools such as Ekahau, giving us the ability to plan signal strength, data rates and mitigate interference. Once a network is in place, we always conduct a verification survey to verify our design and optimise performance. This gives us the ability to get your network working from day one.

With extensive experience in the logistics and manufacturing sector, we understand the challenges warehouse environments face when it comes to connectivity. We also know how to future-proof your business for the future of supply chains through networks that can adopt emerging tech such as machine learning, automation, real-time analytics and hyper-agile connectivity.

We all know that designing WiFi for warehouses is more specialist than the average office building. One of the key points to getting a fast, reliable wireless network in your warehouse is the initial design, but equally important are the wireless products.

There are many interfering factors in the warehouse which can result in a solution offering poorer performance than elsewhere. Warehouse layout, racking arrangement, environment (hot or cold) stock type and how often that stock is moved all affect the performance of the WiFI. In addition, you have the building type ( most warehouses are made from metal which isn’t ideal for radio frequency) plus high ceilings, ceiling angles, and interfering materials all add to the complexity.

For this reason, when proposing a wireless infrastructure for the warehouse we recommend Cambium Networks as it has many antenna options so we can tailor each solution we offer.
