Much of the 802.11ax draft amendment has been written with Internet of Things (IoT) devices in mind. The radio chipsets used for IoT devices generally need to be low-cost and consume very little power. Traditionally, Bluetooth and Zigbee chipsets have been cheaper to manufacture for IoT devices than Wi-Fi radio radios. However, 802.11ax lays the […]
In the world of wireless access points, one size does not fit all. There are choices to be made in ensuring that you have the best technology fit for the requirements of each situation and one of the key considerations is whether to use an Access Point with an internal or external antenna. So how do […]
The term multi-user (MU) simply means that transmissions between an AP and multiple clients can occur at the same time dependent on the supported technology. However, the MU terminology can be very confusing when discussing 802.11ax. MU capabilities exist for both OFDMA and MU-MIMO. 802.11ax defines the use of two multi-user technologies, OFDMA and MU-MIMO. But please […]
The primary goal of both 802.11n and 802.11ac was to provide high throughput and bigger data rates. However, frame aggregation is one key aspect of 802.11n/ac that did enhance airtime efficiency. Frame aggregation is a method of combining multiple frames into a single frame transmission. Fixed MAC layer overhead and medium contention overhead are reduced, […]
For many years, Multi-Dwelling Unit (MDU) environments have struggled to effectively manage and secure their network. A fundamental requirement of an MDU (student accommodation, hotels, assisted living facilities etc.) is to provide a secure, isolated network environment for each user and their associated room. The traditional approach has been to provide each room with a […]
Chris and I discuss the importance of upgrading end user devices when upgrading your enterprise WLAN network in a recent video.
This article covers what the 802.11ax standard is and some common questions regarding this new standard and its accompanying features. Answers Compiled by: David Coleman, CWNE #4 Perry Correll, Aerohive’s IEEE and WiFi Alliance representative Gregor Vucajnk, CWNE #96 1. What is 802.11ax? 802.11ax is an IEEE draft amendment that defines modifications to the 802.11physical […]
Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology are explored. In this final post of the series, we’ll look at how SD-WAN streamlines deployment, while enabling branches to effortlessly connect together via advanced […]
In this video, Chris Harkins, Sr. Technical Instructor and I talk about configuration features like Load Balancing and when (or when not) to use them.
Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology will be explored. WAN connectivity is often a costly investment, whether it’s MPLS, broadband or cellular. Any package purchased through a service provider will be […]
