It's all about access

Access to applications. Access to data. Access to services. Your network has the power to reliably deliver access to data and applications to the right users across your organization. But what happens when the demand for mobility continues to increase? New advances in technologies such as the Internet of Things (IoT), 5G, and Wi-Fi 6 are addressing the need for more mobile access. As a result, the way we’ve built networks in the past is changing for businesses of every size.

Wi-Fi 6 is leading the charge

Wi-Fi 6  is opening up new possibilities for wireless. Improved speed, capacity, and control will not only support existing applications with greater performance and improved experiences but also drive new innovations that will change the way people work.

Wi-Fi 6 began its ramp-up in 2019 and although the standard was ratified in September of that year, Samsung launched a Wi-Fi 6 device in February. Cisco worked with Samsung behind the scenes to validate that Wi-Fi 6 actually delivers faster connections, more capacity, and longer battery life.

Figure 1 outlines the adoption of Wi-Fi 6 in 2019 and where it is going.

Figure 1. Wi-Fi 6 progression

In order to take advantage of all of the benefits of Wi-Fi 6, you will need a Wi-Fi 6-capable network. This includes both access points and Wi-Fi 6 clients. If it hasn't already, the market will soon start seeing large numbers of mobile devices that support Wi-Fi 6. Therefore, it is important to prepare your network for the new standard so you will be ready to gain all the benefits that Wi-Fi 6 offers.

What's the big deal?

Let's start with a basic fact: we are more dependent on the network than ever before and Wi-Fi 6 gives you more of what you need. It is a more consistent and dependable network connection that will deliver speeds up to four times faster than 802.11ac Wave 2 with four times the capacity. This standard provides a seamless experience for clients and enables next-generation applications such as 4K/8K streaming HD, augmented reality (AR) and virtual reality (VR) video, and more device and IoT capacity for high-density environments such as university lecture halls, malls, stadiums, and manufacturing facilities.

Wi-Fi 6 also promises reduced latency, greater reliability, and improved power efficiency. With higher performance for mobile devices and the ability to support the Internet of Things (IoT) on a massive scale (IoT use has been trending upwards lately and is now also called “the new mobile”), Wi-Fi 6 will improve experiences across the entire wireless landscape. Wi-Fi 6 also offers improved security, with WPA3 and improved interference mitigation with better QoE.

The last upgrade to 2.4 GHz was over 10 years ago so if that’s when you last upgraded your network, it’s probably time to make the move to Wi-Fi 6, simply to catch up with the recent technology changes. According to the Cisco 2019 Virtual Networking Index (VNI), there will be higher data rates, with 12.3 billion mobile devices in 2022. IoT will be 50 percent of global connected devices by 2022 (why IoT is “the new mobile”). At the same time, there has been a 27.4 percent average increase in security breaches since 2017, so you want to ensure that your protection is up to date.

In addition to these compelling reasons, following are more significant benefits you can experience when you move to Wi-Fi 6:

  • Higher capacity: Four is the new magic number. Attach up to four times more devices than under previous standards through features such as orthogonal frequency-division multiple access (OFDMA) and multiuser multiple-input multiple-output (MU-MIMO). Wi-Fi 6 communicates in parallel with devices, whereas existing standards communicated only "one at a time". The increased capacity is essential because the volume of mobile data traffic is expected to grow up to four times in just the next four years alone.

  • Improved power efficiency. Using target wake time (TWT), client devices that support the Wi-Fi 6 standard may consume two-thirds less power. This means that batteries in products such as smartphones, laptops, tablets, and IoT devices can last longer, which makes it the ideal standard.

  • Reduced data latency by optimizing packet scheduling, which is ideal for voice, video and gaming applications.

  • Greater IoT coverage by bringing the benefits of Wi-Fi 6 to the 2.4- GHz band.

  • Increased speed. Gain an estimated increase of up to four times in average throughput in congested wireless environments.

  • Improved security. With an extension of security to the infrastructure, the new security features allow for better interference and rogue detection and enhanced threat detection with Cisco® Encrypted Traffic Analytics (ETA). WPA3 is certified with Wi-Fi 6 and provides a greater value proposition than WPA2 for enterprise Wi-Fi networks. It offers enhanced security for open Wi-Fi networks with encryption of unauthenticated traffic, robust password protection against brute-force dictionary attacks, and superior data reliability for sensitive information with 192-bit encryption.

What is OFDMA?

Quite simply, OFDMA is a type of frequency-division multiplexing that is able to use subcarriers more efficiently when it comes to transporting data. Previously, when using OFDM, each user got one time slot, or a whole bandwidth channel. Each user needed to wait in line before they were able to deliver their packet. As more clients join, it took longer for packets to be delivered, resulting in lag time and people waiting to transport data.

OFDMA provides a more regular and consistent packet delivery and users don’t have to wait as long.

Here’s another way to put it. With OFDM, any time a user would request a data packet, it would essentially send out one truck to meet each request of each user, which isn’t very efficient. OFDMA is different, as one truck is used to deliver the packet to individual users in one round. This way is far more efficient and takes less time.

Figure 2 illustrates the difference between OFDM and OFDMA.

Figure 2. Comparison of OFDM and OFDMA

All Cisco Wi-Fi 6 products use OFDMA. As a result, your network will be faster, and most importantly, your users will have a better experience.

Cisco Intelligent Capture

Intelligent Capture is a built-in, enhanced issue detection and root-cause-analysis feature available on Cisco Catalyst 9120 and 9130 Series Access Points. It is software that can track more than 240 anomalies and instantaneously review all packets on demand, emulating the onsite network administrator. With this data, administrators can make more informed decisions on their networks. The software ‘senses’ all packets instantaneously and sends the information back to Cisco DNA Center for deep analysis, making it easier to fix the problem. This way, IT can find any issues in record time. Intelligent Capture also provides live and in-service capture of onboarding failures with PCAPs, a spectrum-analyzer for analyzing interference sources, and on-demand access point statistics for Wi-Fi troubleshooting.

Cisco DNA Assurance with Active Sensor

One of the challenges of wireless is planning for changing levels of demand. A conference or event can introduce a sudden jump in device density or increase expectations on application performance. Cisco DNA Assurance with Active Sensor is a compact wireless device that allows you to test real-world client experiences to validate performance will meet your expectations in any environment.

The Active Sensor can be plugged in anywhere. Other sensor products are often at ceiling level, sometimes providing IT with a less-than-accurate network assessment, since most clients are at eye level. When installed at the level where most mobile devices are apt to be, the Active Sensor allows for a better understanding and a more comprehensive simulation of real clients.

The active sensor validates end-user experience and allows for speed tests to check cloud app performance and connectivity. It also provides IP SLA tests for real-time AppX assessment for VoIP applications.

The Aironet Active Sensor reports data to Cisco DNA Center, where it is used along with assurance data from clients. It comes with multiple powering options, including:

  • Direct AC power plug

  • Power over Ethernet (PoE)

  • Micro USB power

Cisco DNA Assurance puts your data to work; provides you with 360-degree contextual insights across users, devices, and applications; and helps ensure better network performance with real-time and historical data analytics to learn, adapt, and even detect problems before they happen.

Flexible Radio Assignment

Cisco Catalyst 9120 and 9130 Series Access Points both offer Flexible Radio Assignment. FRA is a Cisco innovation designed to provide a better mobile user experience for high-density networks by automatically detecting when the coverage in the 2.4-GHz band is over-saturated. Once the detection is made, Flexible Radio Assignment intelligently determines which access points should change its dual band radio from 2.4 GHz to 5 GHz. Simply viewed, a single physical access point now acts as two 5-GHz access points, resulting in lower channel utilization and a better user experience. The access point performs this function while still monitoring the network for security threats and RF interference that may affect performance.

Flexible Radio Assignment has three different modes of operation:

  • Default operating mode, which serves clients on both 2.4-GHz and 5-GHz bands

  • Dual 5-GHz mode, which serves clients on both 5-GHz radios

  • Wireless security monitoring, which scans both 2.4-GHz and 5-GHz modes for security threats while also serving 5-GHz clients

Flexible Radio Assignment isn’t strictly for workplace environments. It can be used in nearly any instance where a large group of people gather. Whether it’s in an educational setting, a hotel lobby, or a hospital, Flexible Radio Assignment is a boon to any wireless network.

From bring your own device (BYOD) to IoT devices, the proliferation of wireless items brings a new host of challenges as bandwidth-intense applications grow. Flexible Radio Assignment rises to these challenges and augments your wireless network to do more without making your job difficult.

I know what Wi-Fi 6 is, but what is 5G all about?

Think of 5G as the Wi-Fi 6 equivalent in the mobile broadband world. As Wi-Fi 6 is replacing 802.11ac (Wi-Fi 5), 5G is replacing 4G.

However, the most important thing to note is that both 5G and Wi-Fi 6 are built from the same foundation and will co-exist to support different use cases. This is not a matter of choosing one over the other. Both 5G and Wi-Fi 6 promise to dramatically improve wireless experiences for mobile workers and the enterprise. They will both provide higher data rates to support new applications and increases in network capacity, as well as offer the ability to connect more devices. Deployed over wireless devices beginning in 2019, 5G is an advanced way of connecting a wireless device to a network without using Wi-Fi. 5G has a much more massive scale than previous standards of 3G and 4G, allowing for AR/VR to run.

How does Wi-Fi 6 compare to 5G?

Both Wi-Fi 6 and 5G are critical to the future of wireless, but Wi-Fi 6 will continue to be the preferred and primary wireless access in the enterprise, especially for indoor networks. This is because technologies such as smart buildings, indoor enterprises, industrial organizations, and IoT need varying degrees of network connection sophistication that only Wi-Fi 6 can provide. All of these technologies have a common set of problems: onboarding, lifecycle management, security, and data interpretation that can only be solved via a Wi-Fi 6 solution. Add in the fact that Wi-Fi 6 is a reasonable choice—from a cost standpoint to deploy, maintain, and scale—making it an ideal system for indoor wireless connectivity. This is especially true in areas where access points will serve more users, such as stadia, concert halls and convention centers.

On the other hand, 5G might be the designated choice for devices outside an indoor network. With higher speeds and improved capacity, both 5G and Wi-Fi 6 can improve outdoor connectivity. However, certain use cases—like riding on a bullet train at 200 miles an hour or traveling in a car on the highway—will make 5G the preferred method for outdoor networks.

This is not a binary situation, Wi-Fi 6 and 5G are suitable for many industries. Both Wi-Fi 6 and 5G offer exciting opportunities to connect more devices reliably via wireless. This is important for mission-critical IoT devices being used in manufacturing automation, healthcare, energy, and many other industries. Wi-Fi 6 and 5G will also offer enhanced mobile broadband for immersive experiences via augmented and virtual reality. Although many industries will benefit from the enhanced mobile experience, industries such as hospitality, retail, and education will drive immersive experiences for their business.

Products built for the intent-based network

What is intent-based networking (IBN)? As users, devices, and distributed applications have grown in number, the networking environment has become exponentially more complex. An IBN transforms a hardware-centric, manual network into a controller-led network that captures business intent and translates it into policies that can be automated and applied consistently across the network. The goal is for the network to continuously monitor and adjust network performance to help assure desired business outcomes.

How does it work?

IBN builds on software-defined networking (SDN), by using a network controller that acts as a central control point for the network. Such controllers are crucial for network abstraction that lets IT treat the network as an integrated whole. Controller-led networks in all domains (including access, WAN, data center, and cloud) collaborate and extend their benefits throughout the enterprise and help make digital transformation a reality.

The closed-loop system of IBN operates with the following functional building blocks to deliver intent—or support—for the business or IT outcomes that your organization needs:

The closed-loop system of IBN operates with the following functional building blocks to deliver intent—or support—for the business or IT outcomes that your organization needs:

  • Translation - the capture and translation of intent into policies the network can act on

  • Activation - installation of these policies across the physical and virtual network infrastructure, using networkwide automation

  • Assurance - use of analytics and machine learning to continuously monitor the network to verify that the desired intent has been applied and the business outcomes are being achieved.

How does IBN fit in with Wi-Fi 6?

The products that make up the IBN are the Wi-Fi 6 products built specifically for the intent-based network. These products make up the next-generation wired and wireless architecture that best address today’s customers’ needs. Released in November 2018, the Cisco Catalyst 9800 kicked off this technological revolution as the first controller built from the ground up for intent-based networking. It runs on Cisco IOS-XE and can be deployed anywhere. Cisco has married over 15 years of RF innovation—from our Aironet portfolio that offers the most innovative wireless technologies like Clean Air, Intelligent Capture and the most widely deployed controller—with the most powerful networking operating system (OS), that has been modernized with a modular design to give IT higher availability, programmability, and scale.

With the next-generation Wi-Fi 6 wireless products unified under one common OS, Cisco IOS® Software, means that the IBN products are:

  • Resilient, with zero downtime with software updates and upgrades

  • Secure
    • Automated macro and micro segmentation with Cisco SD-Access
    • Threat detection with Cisco Encrypted Traffic Analytics (ETA)
    • Advance security with WPA3 and Trustworthy Systems

Where are some of the best places to use Wi-Fi 6?

The use cases for a Wi-Fi 6 network are numerous and varied. Almost any organization could use faster connection, better battery life, and increased capacity, but there are certain places that may need it more than others.

For organizations that need full-service provider carrier offload and IT/ToT convergence or where networks run in high-density environments such as classrooms and auditoriums and have a need for real-time applications such as enterprise-grade 4k/8k video or augmented or virtual reality, a Wi-Fi 6 network is paramount.

Figures 3 and 4 outline some Cisco products that run in an IBN network using Wi-Fi 6 and common use cases.
