Independent Testing Finds InnerWireless' DAS Improves 802.11 Performance, Extends Asset Life

InnerWireless, Inc., a provider of Converged Wireless solutions, today announced that independent testing of its Horizon distributed antenna system (DAS) with a layered WLAN architecture (L-DAS) delivers significant WLAN operating and financial improvements to enterprises that have high-bandwidth needs for supporting mission- and life-critical wireless applications.

Novarum, which provides service-level performance and independent validation of wireless broadband networks, tested an enterprise wireless LAN system based on 802.11 infrastructure deployed in a conventional microcellular architecture, and the same system deployed using InnerWireless' L-DAS architecture. Novarum reported that the InnerWireless L-DAS allows users to organize client traffic into different isolated layers, which leads to better overall network performance; during the tests, Novarum also found that the L-DAS delivered more than double the data throughput of discrete microcellular systems.

Novarum reported several key findings from its testing, including:

  • Horizon allowed organization of client traffic into different isolated layers, and this led to better performance.
  • Horizon allowed the delivery of more than double the data capacity of the discrete microcellular system in our tests.
  • Horizon exhibited lower interference between APs in the same system than the microcellular system.
  • The clients on Horizon exhibited more uniform and predictable performance.
  • On all of the voice tests, the clients on Horizon had much lower jitter and slightly better MOS scores.
  • Horizon did not compromise the basic functionality of the Wireless LAN system. All of the expected features worked well on the L-DAS.
  • Roaming, voice support, QoS mechanisms and 802.11a/b/g and 802.11n (with 20 or 40 MHz channels) worked on Horizon with the same clients and software as the discrete microcellular system.
