Features and Benefits
Extricom’s WLAN system solution offers the following features:
Ease of deployment - No cell planning
Extricom’s architecture requires no cell planning and experiences no constraints due to RF
interference or channelization. Consequently, Extricom APs can be deployed wherever needed,
in any density or even varying density, to meet the desired end-client service level (stipulated in
terms of connection rate). The traditional site survey is therefore reduced to just physical
equipment installation planning.
Multi-Layer WLAN
Using multiple radio Access Points, 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 user types, traffic, and roles onto different channels.
Same band operation
The Extricom WLAN system enables two WLAN channels, in the same band (e.g. Channel 1
and 6 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 WLAN, 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.
WiFi collaboration
Extricom’s patented WiFi 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 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,
Extricom’s system performance actually increases with AP density.
Wire-line quality VoWLAN
Extricom’s 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.
