What is Operating Mode Indication (OMI)?

In previous blogs, we have discussed both downlink OFDMA as well as uplink OFDMA for true multi-user communications between and 802.11ax AP and Wi-Fi 6 clients. In either case, that 802.11ax access point wins a transmit opportunity (TXOP) and is in control of the medium. During the TXOP, the AP uses OFDMA technology to partition a […]

Why OFDMA is the Secret Sauce for Wi-Fi 6

At the Wireless LAN Professionals Conference, David Coleman (Senior Technical Evangelist) spoke about Wi-Fi 6, and why OFDMA is the most important aspect of the new standard. Watch the video below to learn more about Wi-Fi 6 (802.11ax), how it works, and why it’s important. Key Takeaways What is Multi-User (MU) in Wi-Fi 6? Transmissions […]

Wi-Fi is Going to Get More Efficient – Why You Should Migrate to 802.11ax / Wi-Fi 6

Since we announced our family of Wi-Fi 6 (802.11ax) access points last year, we’ve continued to hear the same simple question from customers. When should we upgrade our network to 802.11ax /Wi-Fi 6? Do we upgrade now, or wait until we have Wi-Fi 6 clients? This question is common whenever a new standard is released […]

The Future of Enterprise Networking: Wi-Fi 6, Machine Learning, Artificial Intelligence, and More

Ahead of our 2019 Channel Xperience Day in Amsterdam, Aerohive’s own Alan Cuellar Amrod (Senior Vice President and General Manager – Products and Marketing) was interviewed by Vincent Everts about a multitude of topics ranging from 802.11ax, Machine Learning, AI, Atom AP30, Aerohive Connect, and more.  Top 5 Takeaways: Speed is just a biproduct of 802.11ax.

6 Things to Expect from 802.11ax (Wi-Fi 6)

On the CWNP Blog, they published a new post called 6 Things to Expect from 802.11ax that is a great read. If you’re having trouble falling asleep, try reading the draft of the latest standard IEEE 802.11ax. David Coleman, CWNE #4 and Senior Tech Evangelist at Aerohive Networks, jokes that while the 682-page document isn’t […]

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 […]
