Welcome to the first in a series of video blogs that will discuss the challenges IT face for meeting the demands of mobility. With greater user expectations for mobility, new mobile devices and end points entering the market and organization environment, you will want to hear some of the insights and strategies addressed in the coming video blogs.In the pilot episode,”Mobility and the Converging Networks,” I interview Ben Gibson, and ask what Cisco is seeing as IT’s challenge for providing mobility to employees and mobile users as they are connecting to more disparate networks (both wired and wireless). Ben provides insight on what and how IT should consider when planning, managing and growing a mobility system. And finally, hear how Cisco sees mobility evolving. Thanks for watching, and stay tuned for a new episode next week!
Few question that the age of mobility is upon us. The emergence of a global economy is facilitated by the basic mobility of goods, services and people. For many, the idea of mobility has become second nature. Of course, the structures for mobility -transportation, logistics, infrastructure -must be robust and reliable lest the mobile quickly become immobile. Given this, it is critical that the wireless industry focus R&D on improving network performance and reliability. What makes this challenging is the need to do this from applications, to the network, and very importantly, to a wide range of mobile devices. To achieve this, businesses should focus on the following key areas when designing a highly available wireless network:- Managing the growth in wireless devices -Managing the growth and diversity of devices connecting to the network requires a continued focus on device compatibility and testing. Through its Cisco Compatible Extensions program, Cisco works with leading Wi-Fi silicon manufacturers to ensure simple, secure connections for a broad range of mobile devices. Another key need is ongoing interoperability testing and validation. While not widely known, Cisco has a very robust program in place, called Assurewave, to achieve just this. Read More »
CRN recently published an article profiling 802.11n performance testing of the Aironet 1250 Series access point. The article titled”Where’s Cisco with Wireless N?” (http://www.crn.com/networking/206905063#community) profiles the results of their testing of Cisco’s 802.11n solution. The article was part of a larger story testing 802.11n products including Meru and Ruckus. Cisco declined to participate in the CRN product review due to basic differences in product testing methodology. Cisco asserts that the review of its 802.11n access point as presented by CRN misses some of the basic principles of product testing and as such is inconclusive on many levels. Firstly, CRN tested a product that was operating with an early version of software. As with any new hardware, users should seek the latest software to ensure optimal performance. The code for Cisco’s 802.11n access point has evolved quickly and the version used by CRN had already been through 4 subsequent releases. The most recent product code is always available for download from the Cisco website -a point that was overlooked by the CRN staff. Read More »
The debate over the readiness of 802.11n and whether businesses should adopt or wait is nothing new. Remember when Ethernet was too unpredictable to displace ATM? IP VPNs too unreliable for critical business data? The adoption rate of new technologies is commensurate with the benefits they deliver. 802.11n offers significant performance improvements over existing standards. Still, for most, the benefits must be evaluated in combination with longevity. In other words, few want to deploy a technology that may soon be obsolete -no matter how great the benefit. Read More »
One can barely open a trade rag these days without reading about the arrival of the next generation of wireless standards – 802.11n. It’s always exciting when new technology hits the market, especially when that new technology truly lives up to the hype. Of course, as with anything new there’s always a bit of misinformation that exists before folks have made it through the learning curve. As I follow the comments of various industry pundits, I’m starting to see a reoccuring theme – misinformation on how to power 802.11n access points. Read More »
