SXT G-5HnD

SXTG-5HnD is a low cost, high speed 5GHz outdoor sector AP, with a Gigabit port, to fully utilize the capacity of 802.11n. At 25° degree beamwidth, you can conveniently create sector setups with a few client devices because this device comes with an AP license (Level4).

Complete with a ready to mount enclosure and built-in 16dBi antenna, the package contains everything you need to make AP, point to point link or CPE.

Package contains SXTG-5HnD, mounting loops, PoE injector, power adapter

All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
Values in Italic indicate that max throughput was reached without maxing out CPU, but because board interface configuration was maxed out
Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
