1Introduction
The iWAP107 is an ATEX and IECEx approved Zone 1 Access Point Enclosure with
intrinsically safe RF outputs; it is designed to allow the deployment of wireless
networks in hazardous areas. The concept allows installation of equipment from
leading WLAN vendors such as Cisco, Aruba, Aeroscout and Motorola. Each type
of Access Point or RF transmitting device is rigorously checked and tested by
Extronics to ensure conformity to the latest standards. This means that the user
may select the vendor of their choice when extending a WLAN to hazardous
areas. However equipment not previously approved will require assessment to
determine its suitability.
The intrinsically safe RF outputs of the iWAP107 allows users to choose any
antenna for use with their wireless hardware e.g. Extronics iANT200 range of
high quality rugged outdoor antennas. Any antennas not listed in the Extronics
range must be assessed by the user to ensure they meet the requirements for
installation of non-electrical equipment in hazardous areas. Up to eight antennas
can be utilized, allowing the MIMO functionality of the latest 802.11n/ac
compatible wireless access points to be implemented, providing optimum
coverage and maximum data throughput on Chemical Plants, Oil Refineries or Oil
& Gas Platforms. Optional features include surge arrestors for lightning
suppression in outdoor installations and single mode or multimode fibre optic
inputs to allow for extended Ethernet link distance.
