Design Guide Introduction:
The industry has been excited about 802.11n from the day the suggestion was made that fast Ethernet speeds might be achievable in the world of Wi-Fi. Now, that standard is ready for mass consumption in the form of the Draft 2.0 version of 802.11n from the IEEE, widely approved by the 802.11 Working Group.
Earlier pre-N consumer products offered, at best, no guarantee of interoperability, forcing early adopters into single-vendor solutions, all without the features and performance to justify enterprise-grade deployments. Draft 2.0 dramatically shifts this trend by bringing stability to the standard, making good on the promise of 802.11n. And the Wi-Fi Alliance has begun certifying interoperability between products that support the standard's high-water mark. This confluence of stability and interoperability transforms the new spec, making it ready for widespread use in WLANs.
Promising to very quickly evolve even the most rudimentary of WLAN installations and the simplest of mobility needs, 802.11n has finally found its way into the enterprise-class wireless LAN market with a new product from Cisco®, the Cisco Aironet® 1250 Series Access Point.
The Aironet 1250 Series access point is a ruggedized, 802.11n Draft 2.0-compliant, modular platform that can simultaneously service 802.11b/g/n devices in the 2.4-GHz spectrum and 802.11a/n devices in the 5-GHz spectrum, all at line rate. The platform's support for Enhanced Power over Ethernet (PoE) and its gigabit-capable Ethernet uplink combine to help ensure that the enhanced access of 802.11n can be placed wherever client access is needed and that each client and application will receive content in a timely and reliable manner. The Cisco Aironet 1250 Series Access Point has been specifically designed to support current and future wireless technologies and to offer unrivaled deployment flexibility, to help you meet the most diverse of WLAN challenges.
