The University of Nevada, Las Vegas (UNLV), founded in 1957, is located in the heart of showbiz industry in Las Vegas. The school offers higher education programs ranging from business, engineering, fine arts and music, and science, and professional schools such as dental medicine and law.
The school’s mascot, Hey Reb, was recently featured on Hulu’s “Behind the Mask,” and you may recognize the Southern Gym during the dance scene between Elvis Presley and Ann-Margret Olsson in the movie Viva Las Vegas.
With over 24,000 unique WLAN users per day, 1.1 gigabytes of throughput per second, and more than 50 wireless access locations across campus providing WLAN coverage, this educational institute demands a massive Wi-Fi network.
In the previous blog, we highlighted some of the Bonjour enhancements of the 7.5 software release and the deployment of Bonjour at St. Margaret’s Episcopal School, a K-12 school. In this blog, we will describe details about UNLVs WLAN deployment, how they use Bonjour services, and give you an insight into rapid pace of innovation necessary to support this technology in the education arena.

Quality wireless is already considered a base expectation by consumers across industries. At Cisco we aim to provide our spectrum of customers with a whole range of high performing products, so they can select the product best suited for their organization. If you were to stop by the Enterprise Networking booth at Cisco Live Milan, you’d be able to examine our full portfolio of access points and notice that there are two that stand out from the others: the newly designed, 802.11ac integrated 3700 AP we introduced at Interop New York and one more, except this one can fit in your hand.
We are pleased to announce Cisco Aironet 700W Series Access Point, a wall mounted wireless and wired integrated platform. 700W Series is the industry’s FIRST and ONLY dual radio, dual band 2.4/5 GHz Access Point with 4 GigE Ethernet ports for wired connectivity, like IP Phones, game consoles, entertainment devices or other connected devices. 700W Series can be powered either by Power over Ethernet (PoE) or by a local power adapter, while it also provides PoE out on one local port to power an additional connected device.

If you’ve been a long time user of Wi-Fi, at some point you have either observed someone encounter (or have personally suffered from) so called “sticky client syndrome”. In this circumstance, a client device tenaciously, doggedly, persistently, and stubbornly stays connected to an AP that it connected to earlier even though the client has physically moved closer to another AP.
Surprisingly, the reason for this is not entirely…errr…ummm…unreasonable. After all, if you are at home, you don’t want to be accidentally connecting to your neighbor’s AP just because the Wi-Fi device you’re using happens to be closer to your neighbor’s AP than to your own.
However, this behavior is completely unacceptable in an enterprise or public Wi-Fi environment where multiple APs are used in support of a wireless LAN and where portability, nomadicity, or mobility is the norm. In this case, the client should typically be regularly attempting to seek the best possible Wi-Fi connection.
Some may argue that regularly scanning for a better Wi-Fi connection unnecessarily consumes battery life for the client device and will interrupt ongoing connectivity. Therefore the “cure is worse than the disease”. But this is true only if the client is very aggressively scanning and actually creates the complete opposite of being “sticky”.
The fundamental issue with “stickiness” is that many client devices simply wait too long to initiate scanning and therefore seeking a better connection. These devices simply insist on maintaining an existing Wi-Fi connection even though that connection may be virtually unusable for anything but the most basic functionality. Read More »

The 802.11ac wireless networking standard is the most recent introduction by the IEEE (now ratified), and is rapidly becoming more accepted and reliable industry standard. The good news is that the client and vendor adoption rate for 802.11ac is growing at a much higher pace as compared to when 802.11n was introduced back in 2009. There has been an accelerated growth seen with the mobile and laptop devices entering the wireless market embedded with an 802.11ac WiFi chipset. Unlike in the past, laptop, smartphone and tablet manufacturers are now acknowledging the fact that staying up to date with the latest Wi-Fi standards is as important for the bandwidth hungry users as having a better camera or a higher resolution display.
With the launch of the new 802.11ac AP 3700, Cisco introduces the Cisco HDX (High Density Experience) Technology. Cisco HDX is a suite of solutions aimed towards augmenting the higher performance, more speed and better client connectivity that 802.11ac standard delivers today.
ClientLink 3.0 features as an integral part of Cisco HDX technology designed to resolve the complexities that comes along with the new BYOD trend driving the high proliferation of 802.11ac capable devices.
So what is ClientLink 3.0 technology and how does it work?

With any new technology comes a new set of obstacles to overcome. 802.11ac is no exception. Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.
What’s Different with 802.11ac?
802.11ac means higher data rates, which means more packets per second (PPS). There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation. Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!
With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS. More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board. Read More »
