It’s always interesting and often entertaining to observe how competitors promote their products and what they choose to focus on—and more importantly, what they choose not to focus on and what they hope people won’t ask questions about.
Consider yet again how a competitor chooses to position their “purpose built” AP vs. the Cisco Aironet 3700 802.11ac Access Point Series.
This competitor frequently (and somewhat obsessively) points out that its 802.11ac AP has dual “active” 800 MHz cores while the Cisco AP3700 has only one “active” 800 MHz core. This is not completely true since it completely overlooks the fact that the Cisco AP3700 also has a dedicated CPU core and DSP for each radio subsystem.
Furthermore, it also overlooks that the dual “active” cores in the competitor’s AP share 512 MB of DRAM. The single “active” core of the AP3700 has dedicated 512 MB of DRAM. Also each radio subsystem has a dedicated 128 MB DRAM (for 768 MB total DRAM in the AP3700).

Northern Kentucky University is among the fastest growing universities in Kentucky. It hosts over 15,000 students with about 13,000 undergraduate and 2,000 graduate students. The goal of the wireless program at NKU is to provide secure, robust and ubiquitous wireless access throughout the campus, both indoors and outdoors. This ensures that students always stay connected and feel at home. The classrooms are equipped with smart technology to ensure that the teachers can benefit from technology when collaborating with students. The IT team has blanketed the libraries, the classrooms, the dorm-rooms as well as the outdoor areas with Wi-Fi. In the previous blog in 2012, we described how the Cisco 7.5 release allows networks to recover with no client re-authentication in the rare event of your primarily wireless LAN controller goes down.

There is a new generation of college students out there, I would know as I recently was one of them. Information being at your fingertips is no longer a luxury, it is a necessity. Professors’ expectations of their students have increased dramatically due to the wealth of information on mobile devices. Every class I attended leveraged some form of wireless access to the web. Instant message in response to real-time questions and online submissions are just two of many examples of how network access has been integrated into the education system. Professors would consistently use online tools such as online drop boxes for projects and web conferencing tools. According to MarketWire 92% of college students feel a laptop is a necessity, this indicates that the requirement of mobile access at a university is a given and the college experience is defined by the ease of that access.
Professors are on tight schedules and are generally available only at certain times of the day. Imagine- wanting to contact a professor during open hours only to fall short because your laptop had difficulty getting any kind of connection. I remember the frustrations of wanting to revisit PowerPoint presentations on a class website in the library, only to realize that I was sitting by the one window notorious for being a wireless dead zone. Dorms were infamous for spotty coverage. Having the dorm room located closest to the access point for best access was purely by luck of the draw. I was not so lucky. In my dorm, you would not get any wireless access unless you were sitting right next to the hallway. That’s why I am especially envious of the students of Colorado University, whose alma mater upgraded to enterprise-class coverage.

The Global Certification Team (GCT) is proud to announce the following additions to the Unified Capabilities Approved Products List (UC APL):
- Cisco ONS 15310-Customer Location (CL) Rel. 9.2.1 TN 1023001, as a Fixed Network Element (F-NE).
- The Cisco ONS 15310-CL SONET Multiservice Platform is an economical, 1-rack unit (1RU)-high delivery platform optimized for use as the last network element—at the customer location (CL)—in a service provider’s network, or for use as an end node in enterprise or campus environments. The Cisco ONS 15310-CL takes advantage of the proven technology pioneered by the Cisco ONS 15454, the industry’s first and leading multiservice optical transport platform.
- Cisco ONS 15310-Metro Access (MA) Rel. 9.2.1 TN 1023002, as a F-NE.
- The Cisco ONS15310-MA is a carrier-class MSPP that efficiently switches Ethernet and TDM traffic for use in metropolitan and regional optical networks. With the flexibility and scalability that allow it to support DS1, DS3/EC1, OC-3 to OC-48 SONET, and Ethernet interfaces, the ONS 15310-MA is already a part of many North American service providers multiservice SONET and next-generation “triple play” and IPTV deployment strategies.
- Cisco ONS 15454 Multiservice Provisioning Platform (MSPP) Rel. 9.2.1 TN 1023003, as a F-NE.
- The Cisco ONS 15454 SONET Multiservice Provisioning Platform (MSPP) provides the functions of multiple network elements in a single platform. It supports common interfaces such as DS-1, DS-3, and EC-1 and data solutions including 10/100/1000 Mbps Ethernet solutions with OC-3 through OC-192 optical transport bit rates and integrated DWDM wavelengths.
- Cisco ONS 15454 Multiservice Transport Platform (MSTP) Rel. 9.2.1 TN 10230047, as a F-NE.
- The Cisco ONS 15454 Multiservice Transport Platform (MSTP) is the most deployed metropolitan-area (metro) and regional dense wavelength division multiplexing (DWDM) solution in the world featuring two- through eight-degree reconfigurable optical add/drop multiplexer (ROADM) technology that enables wavelength provisioning across entire networks and eliminates the need for optical-to-electrical-to-optical (OEO) transponder conversions. The ONS 15454 MSTP interconnects with Layer-2, Layer-3 and storage area network (SAN) devices at rates up to 40 Gbps. It delivers any service type to any network location and supports all DWDM topologies.

According to Cisco’s Visual Networking Index, network operators will deliver upwards of a zettabyte (1021 bytes) of data to 15 billion fixed and mobile devices by 2015. That will be the challenge of the Next-Generation Internet.
To meet that challenge, service providers will need networks that meet the following requirements:
- Support for mobile, business and residential services over a converged infrastructure
- Unprecedented scale and density
- High service availability
- Increased service velocity
- Reduced network complexity Read More »
