Meru's innovations address Layer 2 congestion collapse to dynamically deliver high-performance 802.11n networks and support proliferation of iPads, iPhones, and Android mobile devices in the enterprise

SUNNYVALE, California, March 9, 2011 - Meru Networks, Inc. ( (Nasdaq: MERU), the
leader in 802.11n virtualized wireless LAN solutions for enterprise
networking, today announced that it has been awarded two new patents for its
groundbreaking innovation addressing Layer 2 network congestion collapse in
802.11n wireless LANs (WLANs). Users that introduce iPads, iPhones and other
wireless devices in the enterprise expect an interactive experience while
accessing their latency-sensitive voice, high-bandwidth video and data
applications, regardless of the number of mobile devices on the Wi-Fi
network. However, existing rate adaptation technologies often lead to
significant reduction in the network speed experienced by users. The rate
adaptation frameworks and methods covered in Meru's Patent no. 7,808,908 (1)
and Patent no. 7,756,059 (2) enable the delivery of critical enterprise
applications at the optimal transmission rate for each device, taking into
account network congestion, loss rate of the channel, and the distance and
mobile or stationary state of the device. Solutions that do not properly take
these critical factors into account typically force the network to operate at
the wrong data rate; which, as the number of mobile devices proliferates on
the wireless network, causes it to struggle with high-congestion, dropped
connections and potential network collapse. Incorporated into their
virtualized WLAN suite of solutions, Meru's innovative rate adaptation
technology addresses Layer 2 congestion collapse for wireless networks by
dynamically transmitting at the optimum data rate, which results in higher
throughput, providing enterprises with a high performance solution that
supports increasingly dense environments and helps organizations avoid a
Wi-Fi Meltdown(TM) (


    Key Facts

    - 802.11n implementations use rate adaptation to determine the highest
      data rate at which a given device can transmit, based on their position
      relative to an access point. However, this approach is not effective
      in dense environments, mistaking network congestion for distance and
      causing devices to take more time to transmit the same amount of data,
      slashing network capacity to fractions of what the network was
      designed to handle.

    - These two new patent awards further validate Meru's leadership in
      innovation. Meru's previously announced Patent no. 7,826,426 (3), which
      highlighted Meru's Virtual Port(TM) innovation
      (, was
      invented to address wireless network congestion. Specifically, its
      patented Virtual Port technology provides wired switch-like bandwidth
      optimization and security for enterprises that increasingly need to
      manage environments with a growing density of iPads, iPhones and
      similar next-generation Smartphone devices, such as Android-based

    - Meru's core technology and virtualized architecture is purpose-built to
      support the proliferation of wireless devices and applications and,
      more critically, to help avoid Wi-Fi Meltdowns, as demonstrated with
      Meru's WLAN 500(TM) demonstration
      With over 500 wireless devices in a 500 square foot area, Meru's
      wireless network solution streamed voice, video and data concurrently
      and delivered full quality of service to all devices, whether mobile
      or stationary.

"The mandate for today's CIO has changed more than any other C-level
executive over the past five years. Organizations are looking to their IT
departments to help make workers more productive while lowering the cost of
IT. The move to an All-Wireless Enterprise(TM) is one current IT trend that
can achieve both goals. While this vision has been on the horizon for years,
the technology to support it has not been available until now. With Meru,
customers now have a virtualized WLAN technology solution to achieve a
competitive advantage."

Joe Epstein, senior director, technology, Meru Networks

"Wi-Fi Meltdowns are caused in large part by wireless devices doing the
wrong things when the network gets congested, even if they do the right
things in lightly loaded environments. As the number of wireless devices such
as iPads and smartphones converge on a given area, Meru's innovative
signal-to-noise rate adaptation intelligently restores airtime fairness -
overcoming the flaws associated with 802.11n implementations and avoiding a
Wi-Fi Meltdown. As the leader in 802.11n innovation, Meru again demonstrates
how our products are designed from the ground up to avoid the problems of
scale-out wireless networking that legacy microcell technology has not been
able to address."
