What power supply does it use?

Includes 24V 0.5A Gigabit PoE adapter with passive PoE (pairs 4,5+; 7,8 return), supporting 20-27V DC range and max 8W consumption. Simplifies outdoor deployments without separate injectors.

What are the environmental specs?

Operates from -40 to 70°C (-40 to 158°F) and 5 to 95% non-condensing humidity. UV-stabilized plastic enclosure and pole mount ensure reliability in extreme outdoor conditions.

What frequencies and channels does it support?

Worldwide: 5150-5875 MHz; US/CA: 5725-5850 MHz. Channel sizes: 5/8/10/20/30/40 MHz with dual linear polarization for flexible airMAX deployments.

What hardware specs does the processor have?

Atheros MIPS 74Kc at 560 MHz with 64 MB DDR2 RAM and 8 MB flash. Single GbE RJ45 port enables high-speed bridging with airMAX technology.

Is it suitable for enterprise PTP links?

Yes, RF isolated reflector and 25 dBi dish provide noise immunity and directivity for reliable point-to-point backhaul up to 25+ km at 150+ Mbps.
