simultaneous data streams. Such technology is capable of increasing data throughput via
enhancements such as spatial multiplexing (data streams), 40MHz channel bonding, Block
Acknowledgment and frame aggregation, and use of spatial diversity to increase range.
Feature Highlights
The Extricom Series WLAN system solution offers the following features:
Ease of deployment - no cell planning
The Extricom Series architecture requires no cell planning and experiences no constraints due to
RF interference or channelization. Consequently, Extricom Series APs can be deployed wherever
needed, in any density or even varying density, to meet the end-client’s desired level of service
(stipulated in terms of connection rate). The traditional site survey is therefore reduced to simple
examination of the space in order to plan the location of the physical equipment.
Multi-Layer WLAN
Using multiple radio Access Points (APs), a single set of APs enables deployment of multiple
high-data-rate Channel Blankets with overlapping coverage, resulting in multiplied aggregate
capacity. Separate Channel Blankets also offer the unique ability to guarantee Quality of Service
by physically segregating different types of traffic (based on service class, user type, and
administrative privileges) onto different channels.
Same-band operation
The Extricom Series WLAN system enables WLAN channels, in the same band (for example,
Channel 1, 6, and 11 in 2.4 GHz), to be simultaneously used within the same AP, to form
overlapping Channel Blankets using the same physical set of APs.
TrueReuse bandwidth
TrueReuse technology multiplies the bandwidth of a standard 802.11 channel by dynamically
optimizing the reuse of each frequency. Within a Channel Blanket, up to three APs are permitted
to simultaneously transmit on the same channel, when the TrueReuse algorithm determines that
they can do this without causing each other co-channel interference.
Zero-latency mobility
In an Extricom Series WLAN, a wireless device remains on the same channel everywhere within
the Channel Blanket. Inter-AP handoffs delays or packet loss do not occur as the client moves
across the range of different APs.
Wi-Fi Collaboration
The Extricom Series patented Wi-Fi Collaboration technology, in which all APs are able to
receive on the same channel, provides uplink path diversity for client transmissions, making the
system highly resistant to RF instabilities and outside interference.
Dense AP deployment
In an Extricom Series WLAN, APs can be deployed in any density convenient to the enterprise, to
achieve both blanket coverage and a guaranteed communications rate to all users. In fact, while
cell-based
solutions shy away from dense deployments because of their inherent RF obstacles, the
Extricom Series system performance actually increases with AP density
.
Wire-line quality VoWLAN
The Extricom Series Interference-Free architecture is perfectly suited for VoWLAN providing
zero-latency mobility, voice and data separation, reduced power consumption, and high RF
resiliency, all together resulting in superior voice performance.
