802.11ac is the hottest topic of discussion and deployment in WiFi over the past couple of years. Ratified as a standard by the IEEE in November 2013, the first phase of 802.11ac products brought to market is commonly referred to as Wave 1, and provides roughly a 3x improvement in network performance over its predecessor 802.11n: 1.3 Gbps compared to 450 Mbps in 5 GHz respectively when utilizing the maximum channel width and modulation supported .
Next up 11ac Wave 2, the next phase in 802.11ac, will begin entering the market later in 2015 in the form of both new client devices (smartphones, tablets, laptops) and new Access Points and modules, providing two significant enhancements building on Wave 1
Multi User MIMO MU-MIMO
160 MHz channel width support
MU-MIMO will enable a Wave 2 AP to talk with multiple Wave 2 clients Read More »
If the phrase “multigigabit switching” is not in your personal knowledge base yet, you are not alone – it’s very new. But going forward, you’ll hear a lot about it. Here’s why. Multigigabit switching is an emerging technology that shatters the Ethernet speed barriers found in the LAN infrastructure that most of you have today. It’ll extend the life of your current access LAN for years to come, while helping you get ready for new technology trends that are rapidly approaching.
Instead of being limited to no more than 1 Gbps on a Cat 5e or Cat 6 LAN, which comprises most of existing access LANs, multigigabit switching can support speeds up to 5 Gbps without any required changes to the cabling system. To get a quick idea how useful it is, click the picture below to watch a preview video.
“Why do I need such fast speeds – shouldn’t 1 Gbps be sufficient?” you might ask. Well, the world is moving so fast that new technologies are soon demanding more speed than gigabit. Consider the following use cases: Read More »
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 »
Whether you are among the 8,000 attendees participating at Cisco Live Milan in-person or among our many virtual attendees catching the live web broadcast, you’ll find lots to help you with your mobility-related projects.
By Lisa Garza, Cisco Service Provider Marketing, Mobility Solutions Everything old is new again, and that’s true for voice over Wi-Fi. When Apple announced support for Wi-Fi calling on the new iPhone 6 this fall, a new hype cycle was born. In the most extreme cases some industry players are claiming the resulting death of residential licensed small cells. As in most technology introductions, the truth will unfold over time as the technology is applied in the real world. If voice over Wi-Fi were a simple panacea, then we would all Read More »
