hi guy's, we have a epmp1000 in ptp master slave link from 330m awaym and near LOS. we see each module . link is 200mbits, -53Db, 4ms ping. but i do not know the signification for the 'ealign' tool.
in the tower , module A, the ealign tool variate from -45 to -80 Db very rapidly. and from basement module B, ealign is very stable around -53Db. is somebody explain to me?
The eAlign tool is supposed to help installers with the process of alignment of the subscriber modules (physically set the subscriber module in a position where it gets the strongest and most balanced signal possible) for better performance.
Is your unstable eAlign results coming from the device in ePTP Slave or Master mode? If it is coming from the ePTP Master, I believe it is a RSSI misreporting due to an implementation defect.
indeed, the eptp master is located in a tower, yesterday the wind mostly pull me out of the tower. lots af vibration. is vibration can cause this issue
version is the last. 2.6.1, the graphic below goes from -45 to -80.
antenna s is , Epmp1000, distance 335meters, water tower hight 225 foot, attached to the frame. integrated antenna, outdoor shielded network cable. this is the water tower, both Epmp are near LOS
hi, i heard about the freznel zone, how do we calcul it in the 2.4ghz? there a pille of rock in front of the slave. do you think there is a problem with that? the slave is located on the garage side and i can move the antenna at the top with a 10 foot pole. so it could be 25 foot higher.thank you for your time
BTW, which ePMP1000 platforms are you using as Master and Slave? I see your Slave in the picture is a ePMP1000 with Integrated Antenna. Are you using the same as Master?
hi, i calculate the fresnel zone, result is 13,foot at mid distance, & 10 foot for 80% fresnel.
so i think it is the point from the garage, we have a rock pile in front of the antenna, so it give near LOS, on thursday, il will reinstal the garage antenna, on the garage top, with a 10 foot mast. it think it will help a lot.
hi, i have moved the antenna higher, a the garage's top and put the acces point at the water tank in ''accespoint standard wireless'' , station at the garage and at the main entrance in SM with wireless.
RSSI signal is then normal at -52 for the garage & -48 for the main entrance. i think that the RSSI issue is solved.,
