INDUSTRIAL OUTDOOR HIGH THROUGHPUT
802.11A/N WIRELESS ETHERNET
Thank you for purchasing NetWave® from ComNet. This installation guide applies to
the following models:
NW7: Industrial Multipoint, FCC Version, User Configurable
NW7E: Industrial Multipoint, ETSI Version, User Configurable
NWK7: Industrial Multipoint Kit, FCC Version (Includes NWK7_AP and NWK7_CL)
NWK7E: Industrial Multipoint Kit, ETSI Version (Includes NWK7E_AP and NWK7E_CL)
The NetWave industrially hardened wireless Ethernet transmission link from
ComNet can be configured through the embedded User Interface as a Client or as
an Access Point. This point-to-multipoint model allows multiple Ethernet endpoints
to be connected to a central Access Point. Up to 15 endpoints can be linked to a
central access point. This single radio model was designed for high throughput
point-to-point or multi-point applications and comes with an integrated 19 dBi, 17º
beamwidth antenna. The NW7[E] supports up to 240 Mbps throughput using MIMO
technology. The units can be powered by an 802.3af/at PoE compliant device or
through a sold-separately PoE injector with the second Ethernet port serving as an
IEEE802.3at power source. The NW7 is FCC certified and the NW7E is ETSI, DFS and
TPC certified.
