By Vince Pandolfi, Consulting Systems Engineer, Service Provider The latest Wi-Fi physical layer standard 802.11ac, has been ratified and is enjoying widespread adpotion in the client device marketplace. The hype has been with us for a few years now proclaiming tremendous gains in throughput. The mechanisms 802.11ac uses to gain these speed improvements can also be used to improve client quality of experience and not necessarily just be used for higher data rates. The three key elements of a connect include distance, speed and reliability. These are in most cases mutually exclusive or at least have inverse relationships. You gain distance by trading throughput and reliabilty and gain Read More »
As more and more users and devices are connecting to the network via WiFi, Cisco has been focused on creating the best wired network to enable mission critical wireless:
- In 2013, we introduced Catalyst 3850 & 3650 Stackable Converged Access Switches for wired & wireless networks. These switches simplified networks by combining separate wired and wireless networks into a single platform. This simplification makes IT agile. These switches also enabled a better user experience through deeper application visibility across wired and wireless with Cisco Flexible NetFlow. Click here to see an interactive demo showing the other benefits of our converged access switches.
- In 2014, we expanded the converged access portfolio by introducing Converged Access on Catalyst 4500E, our lead modular access platform.
- Today, we take the next big step in our wireless strategy by introducing Cisco Catalyst Multigigabit technology across several campus switches: Catalyst 4500E, 3850 and 3560-CX.
So, what problem does Cisco Catalyst Multigigabit technology solve? Read More »
The Cisco Enterprise Mobility group uses this mobility blog as a platform to provide you the most up-to-date information about our products and solutions, showcasing our thought-leadership in the mobility industry and innovative and comprehensive portfolio. So let’s revisit some of those topics we covered over the last year.
The transition to 802.11ac has been swift. Two months ago, Cisco announced crossing 1 million units sold for 802.11ac. It’s a testament to just how pervasive Wi-Fi has become. These days, Wi-Fi needs to always be available, and it needs to be quick, no matter the mix of applications on the network.
Miercom recently published a third-party report testing these two areas – high availability and real-time voice / video performance of Cisco, Aruba, and Ruckus.
The recent release of the Cisco® Universal Wi-Fi solution for service providers is the industry’s first end-to-end solution with HD VoWi-Fi (Voice over Wi-Fi) as a key feature. This focus on Voice signals a significant turning point in the role of Wi-Fi in Mobile Network Operator Networks (MNOs).
Up until now, while Wi-Fi access has widespread acceptance by MNOs globally, its focus has been for low $ yield best-effort traffic. Wi-Fi’s significantly lower cost per bit TCO has made it attractive for taking on the bulk of the insatiable mobile device data demand in recent years. However now we see a shift in this approach, from looking at Wi-Fi as a secondary “best-effort” access only to also being a supplementary access for real-time services i.e. Voice.
The culmination of several enhancements in the Wi-Fi end-to-end solution Read More »
