Migrating to Wi-Fi 6E: How to Plan Your Network Upgrade

What is Wi-Fi 6E all about? What does network migration look like in Polish and who will benefit the most from the change in WLAN technology? These and other questions about Wi-Fi 6 will be answered by Marek Surmacewicz, Network Security Systems Engineer at Versim, a leading distributor of Extreme Networks network solutions.

In a word – Joanna asks, Marek answers.

What’s the fuss about Wi-Fi 6E? Is it such a step forward?

Migrating to Wi-Fi 6E is a step that more and more companies must consider to keep up with growing technological requirements. The new standard is not only an additional 6 GHz band, but also greater efficiency, reliability and security. The change is due to, among other things, an increase in available bandwidth, which allows for the demand for video streaming or gaming functions. Thanks to this, wireless networks can better meet the needs of modern organizations, especially those operating in demanding environments such as warehouses, production halls or offices with high device density.

How does Wi-Fi 6E differ from its younger sister Wi-Fi 6?

Wi-Fi 6E makes a significant difference, offering the 6 GHz band. The new radio provides additional communication channels that are free from interference, which allows for more efficient network planning and better management of devices in spaces with high user density. Additionally, this standard offers better security and functionalities that eliminate the problems known from earlier generations of Wi-Fi. It is an ideal solution for spaces where network capacity, coverage and stability are crucial – from warehouses with high racks, through corporate offices, to sports stadiums serving tens of thousands of users at the same time.

Let’s assume that we have decided to migrate the network. What does such a migration involve?

It is the process of switching to a new technology, which often involves replacing devices and adapting infrastructure. While changes in wired networks are relatively slow, in the case of Wi-Fi we are observing dynamic technological leaps – from Wi-Fi 5 through Wi-Fi 6, to Wi-Fi 6E and the upcoming Wi-Fi 7. In Poland, migrations often concern long-used equipment that has been in use for even 10-15 years. Modernization becomes necessary when the technology becomes outdated and does not support new standards of user devices, such as modern readers or smartphones. Therefore, I would suggest migrating to at least Wi-Fi 6E right away.

So what should we consider during the migration process?

The implementation of Wi-Fi 6E is not just about replacing access points. Migration requires the involvement of the customer’s IT team, which provides detailed information about the existing infrastructure. Then, an analysis is carried out of the possibilities of integrating the new equipment with the current environment. Depending on the customer’s needs, various options are available, such as implementing local controllers or a cloud solution. It is crucial to properly plan the entire process to avoid network downtime and properly serve end devices.

For example, if the company plans to launch applications with high requirements, such as videoconferencing on production floors, the network must be optimized for roaming and performance. In such a situation, Extreme Networks technology stands out for its ability to precisely design the network, which adapts the location of access points to the specific needs of the organization. Of course, the key to the process is to conduct Site Survey measurements and take into account the requirements, constraints and budget that the customer has at their disposal.

What about transmission security if we use older devices in the network?

Security is one of the key aspects of the new generation of networks. Wi-Fi 6 and 6E introduce the WPA3 standard, which significantly increases the level of data protection, eliminating vulnerabilities known from earlier standards. However, it is worth remembering that older devices may require lower encryption standards. If the organization uses outdated devices, consider assigning a separate SSID for them or modernizing them. In such cases, Extreme Networks offers features that make security management easier, such as Private PSK (unique keys for each device) or cloud-based network management systems.

What else should we remember when migrating?

When migrating to Wi-Fi 6E, environmental issues cannot be ignored. Extreme Networks access points are adapted to work in demanding conditions, such as high temperature or dust. More resistant models operate in the temperature range of -40°C – +60°C (e.g. AP5050D). Sometimes external cooling enclosures must be used, which ensures stable operation even in extreme temperatures.

The implementation of Wi-Fi 6E is also an opportunity to modernize the wired infrastructure. Thanks to multi-bandwidth ports in switches, the network can better handle increasing bandwidth requirements. In the case of Extreme Networks, the use of Fabric technology allows for simplifying infrastructure management and its integration with cloud systems.

So much for the theory. But what does it look like in practice?

Practical examples show how diverse Wi-Fi 6E applications are. The Borussia Dortmund stadium has implemented an Extreme Networks network that supports thousands of users simultaneously, ensuring smooth operation and the ability to locate users. The Dino network warehouses use directional antennas to minimize interference and small cells are used in hotels to optimize coverage and roaming. Thanks to better performance, more available channels, and a higher level of security, the network is faster, more stable, and ready to support increasingly advanced devices.

Sounds good, but what if we don’t want to migrate for various reasons?

Limited support for older devices, such as Wi-Fi 5 access points, means that their continued use becomes problematic. We know that manufacturers, including Extreme Networks, are phasing out technical support for outdated models, which prevents their integration with new technologies. Ultimately, failure to migrate can lead to significantly higher costs associated with maintaining the network.

Summary

Migrating to Wi-Fi 6E is an investment in the future that brings benefits in the form of better performance, security and flexibility. It is a decision that not only improves the quality of the network but also secures its operation for years to come.

In addition, by implementing Wi-Fi 6E, we also gain compliance with new regulations, such as the NIS2 directive, which is important for many business sectors.
