Why Private Pre-Shared Key (PPSK) is a Simple and Scalable Way to Secure Your Wi-Fi Network

We know that our customers have different network requirements and need to support all different types of various devices. While devices like Mac and PC laptops work great with 802.1x, there are plenty of situations where IT managers don’t want to go through the process of deploying it. How can you have great enterprise Wi-Fi […]

What is UL-OFDMA Random Access (UORA)? – Part 2

In our last Wi-Fi 6 blog, we discussed a method in which clients can allocate resource units for uplink transmissions instead of the AP making the decision 802.11ax provides for an optional UL-OFDMA random access (UORA) method. A random-access method is favorable in conditions where the AP is unaware of traffic buffered on the clients. […]

What is UL-OFDMA Random Access (UORA)?

As you have learned in previous blogs, an 802.11ax access point uses OFDMA technology to partition a channel into smaller sub-channels called resource units (RUs) so that simultaneous multiple-user transmissions can occur. The AP mandates the RU allocation for multiple clients for both downlink and uplink OFDMA. In simpler words, the AP is in charge of how RU […]

Unsolicited Buffer Status Reports in 802.11ax and Wi-Fi 6

In a previous blog, we focused on the delivery of buffer status reports (BSRs) from Wi-Fi 6 clients using an explicit process that requires polling from the AP. To summarize the solicited UL-OFDMA frame exchange we discussed, the following three trigger frames might be used: Trigger 1: BSRP to solicit buffer status reports from the clients […]

Uplink Orthogonal Division Multiple Access (UL-OFDMA) in 802.11ax

As we discussed in a previous blog, an 802.11ax AP must contend for the medium and win a transmit opportunity (TXOP) before multi-user (MU) communications can occur. Once the 802.11ax AP wins a TXOP, it can then coordinate uplink transmissions from 802.11ax clients that support UL-OFDMA. UL-OFDMA is more complex than DL-OFDMA and may require the […]

Uplink OFDMA is not PCF

In the previous blog, we discussed DL-OFDMA and the 802.11 frame exchanges between an 802.11ax AP and multiple 802.11ax clients for multi-user downlink transmissions. In future blogs, we will discuss the necessary UL-OFDMA frame exchanges to achieve synchronized multi-user uplink transmissions. However, there is already some confusion between UL-OFDMA and some legacy RF medium access methods. […]

How Does DL-OFDMA Work in 802.11ax?

You should always remember that multi-user OFDMA communication is only for 802.11 data frame exchanges between an 802.11ax AP and multiple 802.11ax clients. For backward compatibility, management and control frames will still be sent using single-user OFDM. In a previous blog, we mentioned that a series of frame exchanges are used for both DL-OFDMA and […]

How to Secure IoT Devices with Aerohive A3

Are you struggling with IoT security and device management? Are you still wondering how to secure IoT devices based on all the information you’ve read in the news? Let’s take a closer look at how the next generation Secure Access Management with Aerohive A3 can help IT managers boost network security and control for a […]

What are Cloud Configuration Groups used for?

In an earlier blog, we announced Cloud Configuration Groups, a new HiveManager configuration and network device management feature. Cloud Config Groups is a new form of device classification that adds more flexibility when configuring network policies with HiveManager. Cloud Config Groups solves the management challenge of implementing template-based network policies for network devices that require […]

What are Private Client Groups?

Earlier this year, we discussed Room Area Networking. In the video below, David Coleman and Liwei Wu discuss Private Client Groups. They discuss the use cases, the technology powering it, and why PPSK is so important for it to work. Private Client Groups provides secure, isolated, per-room networks while operating across a single SSID and […]
