802.11n represents the next evolutionary step in standards-based wireless networking and a sea change
to the level of mobility on enterprise networks. Featuring numerous enhancements to the physical and
MAC layers of 802.11, it is a complete overhaul of previous Wi-Fi technologies and will facilitate the
mobilization of bandwidth intensive applications across all industries. Historically, careful planning and
point optimizations were required to deploy high throughput applications over bandwidth constrained
802.11a/g networks. Now with the advent of 802.11n and its data rates upwards of 300Mbps, bandwidth
is increased roughly 6X over today’s 54Mbps WLANs offering breathing room for even the most
demanding use cases. Cisco has made 802.11n Draft 2.0 capabilities available to enterprise-class
customers with its Aironet 1140-series Access Point. Sporting 802.11n in both the 2.4GHz and 5GHz
frequency bands, this Access Points permits mobility for high throughput applications and increases the
reliability and predictability of WLANs.

The Cisco Aironet 1140 series access point caters to indoor environments that demand outstanding
wireless performance while blending in seamlessly with the aesthetics of the enterprise environment. In
order to meet these set of requirements, the Aironet 1140 was designed with integrated antenna elements
similar to its predecessor, the Cisco 1130AG. This access point includes six integrated Omni-directional
antenna elements segmented into three discrete elements for each frequency band. Ideal for indoor
environments, this access point has a low-profile design that blends into enterprise, health care or
educational environments seamlessly. Featuring two integrated 802.11n Draft 2.0 radios, the AP can
simultaneously serve 802.11b/g/n and 802.11a/n clients in the 2.4GHz and 5GHz bands, respectively. In
addition to a Gigabit Ethernet uplink, the 1140 also supports full functionality while being powered by
802.3af Power Over Ethernet.

It's About More Than Speed
The new standard is fast-really fast, but 11n is not just another acceleration of business as usual, and it's
far more than a step forward in performance. The dramatic advances of 11n come in two areas that have
challenged many wireless network administrators: reliability and predictability.

Achieving the reliability of wired transmissions with a wireless medium is inherently difficult, and
designers have grown accustomed to architecting WLANs around this. For example, bandwidth
considerations notwithstanding, most implementers are comfortable planning legacy access point (AP)
placement with restrictive voice-over-IP client count limitations due to the increase in 802.11 retries
