5 Issues that impact Wi-Fi performance in dense environments

Worldwide data and video traffic are growing at double-digit rates. This increase is driven by connected devices and applications like 4K video streaming, VR/AR and eSports. Adding to the complexity of this environment impacting Wi-Fi performance are diversifying device categories and apps, such as headless IoT devices, video and voice-over-Wi-Fi.

Moreover, the congestion of people, devices and bandwidth-hungry apps makes for numerous real-world challenges that conventional wireless technology has difficulty overcoming, especially in dense environments. Let’s take a closer look at some of these challenges below.

Wi-Fi performance

Overloaded network

Wi-Fi antennas often radiate signals – like a lightbulb radiates light – in all directions. This can create misdirected and wasted radio energy.

The solution? Ruckus BeamFlex+ technology, which enables the antenna system within a Ruckus access point (AP) to dynamically sense and optimize for its environment. The antenna system also significantly bolsters range and Wi-Fi performance by mitigating radio interference, as well as noise and wireless performance issues.

Too many devices

All access points use ‘lanes’ (radio channels) to transmit and receive traffic. However, a specific lane can become congested, leaving an AP unable to determine if other lanes are free to accommodate wireless traffic.

The solution? Ruckus ChannelFly dynamic channel management, which helps our APs boost Wi-Fi performance by dynamically (automatically) switching a client from a crowded channel to a less congested one.  

Wasted radio energy

Excessive management traffic typically saturates available Wi-Fi spectrum in dense Wi-Fi environments. This results in reduced connectivity and low per-client throughput.

The solution? Ruckus Airtime Decongestion, which enables APs to more selectively respond to clients. This dramatically increases overall network efficiency for higher airtime utilization and delivers a more optimized user experience.

Channel congestion

APs are frequently overloaded with an uneven client load in dense network environments. This inefficient utilization of network capacity results in a sub-optimal client-to-AP link quality and lower throughput for clients.

The solution? Ruckus Network Capacity Utilization, which employs real-time learning techniques to associate clients with APs that offer higher link quality and capacity. This mechanism facilitates higher overall network capacity and …

The evolution of Wi-Fi 6: part 3

In part two of this series, we explored the basics of MU-MIMO, OFDMA, and 1024-QAM. In this blog post, we’ll take a closer look at Wi-Fi speeds, along with an in-depth look at OFDMA, MU-MIMO and BSS Coloring.

Wi-Fi 6

Theoretical peak speeds vs. network capacity and efficiency

As we’ve emphasized throughout this series, the 802.11 standard has rapidly and significantly evolved over the past two decades. For example, wireless LANs once focused on achieving theoretical peak speeds. With the advent of Wi-Fi 6 (802.11ax), the emphasis has shifted to overall network capacity and efficiency, in addition to throughput speeds. As the latest iteration of 802.11, Wi-Fi 6 (802.11ax) is expected to become prevalent in ultra-dense environments such as transport hubs, urban apartment complexes, college campuses, concert venues and sports stadiums. These are all locations where many clients routinely access the internet over Wi-Fi, as well as share UHD content and stream 4K video. 

Currently, in advanced development, the IEEE 802.11ax standard is slated to be released in 2019. It is worth noting that the maximum theoretical speed of Wi-Fi 4 (802.11n) was 150 megabits per second, per stream. Wi-Fi 5 (802.11ac) increased this to a theoretical speed of 866 megabits per second, per stream, which is considered a six-fold jump. Wi-Fi 6 (802.11ax) supports maximum speeds of up to 1201 megabits per second. Although Wi-Fi 6 is certainly faster than its predecessor, it is not the six-fold increase seen with the release of Wi-Fi 5 (802.11ac). 

Wi-Fi 6: 4x increase in throughput

More specifically, Wi-Fi 6 (802.11ax) is expected to boast a 4x increase in throughput for the average user. This is primarily due to more efficient spectrum utilization and various improvements for dense deployments. Clearly, speed is not the most important issue, as the maximum rates are notoriously inaccurate when it comes to real-world performance. These can vary widely based on a range of obstacles, other signals in the air, multipath reflections and the capabilities of both access …

Ruckus ICX 7850 Switch Delivers 100GbE Edge-to-Core Solution for Multi-Gigabit Enterprise Networks

Ruckus Networks, an ARRIS company, has expanded its extensive switch lineup with the ICX 7850. The new switch is specifically designed to provide a complete edge-to-core solution for campus networks well into the next decade.

ICX 7850

“The ICX 7850 delivers high-end routing and security capabilities suitable for large campus networks in a fixed form factor,” said Siva Valliappan, Vice President of Wired Products, Ruckus Networks, an ARRIS company. “Perhaps most importantly, our stackable ICX 7850 provides the power, performance, and reliability of a chassis with a pay-as-you-grow model. This makes the ICX 7850 a cost-optimized solution for complex network requirements across a range of verticals and businesses including education, government, enterprise and service providers.”

As Valliappan notes, recent advances in Wi-Fi technology, such as Wi-Fi 6 (802.11ax), the IoT and LTE are all driving the demand for multi-gigabit access by significantly increasing the amount of data traversing enterprise edge networks.

“Enterprise and data center networks are being pushed to the breaking point and the capacity of traditional 10 Gigabit Ethernet (GbE) backbones is being tested,” he explained. “The ICX 7850 can help by enabling seamless replacement of existing 10G products with a high density, secure, scalable platform. The ICX 7850 supports high density 10GbE, 25GbE, 50GbE and 100GbE using existing customer investment in fiber cabling to enable unprecedented network growth.”

Many organizations, particularly school districts with older, existing networks have OM1 or OM2 fiber optic cables that require Long Reach Multimode (LRM) optics to achieve the 10 Gbps connections needed for today’s bandwidth needs. The ICX 7850 provides investment protection and an upgrade path for customers with older fiber infrastructure by offering support for LRM optics with select family members.

Pay-as-you-grow with the ICX 7850

As we noted earlier, the ever-increasing need for Wi-Fi connectivity is taxing the network core, although the solution to keeping pace with the proliferation of connected devices and advances in Wi-Fi technology does not need to be complex and expensive. While the introduction of multi-gigabit connectivity at the edge is driving the need for …
