LHG 60G experience

Stril · March 17, 2019, 5:49pm

Prior to thinking, these products will be better than the LHGs, just read the UB-forums and search for FCS-errors and corrupted packets…

Just added an LHG to take over the traffic of an AirFiber…

Friends, help calculate the track and its reliability.
Going to do PTMP.
As the base I want to use Wap
The first client at a distance of 160 m. LHG
The second and third on the same building at a distance of 490 m. LHG

How much such a link will be reliable, whether there will be frequent problems with it. What signal do I expect from distant links?

I am reporting some weird findings. The device is connected on an HP A5500 48port PoE+ switch worth 7,000+ euros. There are 3 other LHG60 on the same switch all working properly/normally. There are 35 VoIP phones on the same switch all working properly.

Even when switching off the PoE power from the switch port the antenna stays on! Or at least its LEDs are on.

It will only go off when disconnecting the ground cable!

The weird findings continue. When disconnecting the ground cable the problematic antenna comes back to life and the link works. When connecting back the ground cable it goes crazy again.

The same ground is used for all the other 4 LHG60s on that roof and the rest behave/work normally.

Should I use the ground or not? Is it better to use the Ubiquiti surge arrestors instead of the ground? Should I use both?

I had people check the earthing itself and it is fine.

I could not find documentation on the matter

Hi,

Earlier today a network loop was introduced in our internal network. While investigating the source of the loop we disconnected the 4 links with other buildings that we have using LHG60s and a link with wAP60. While rebooting one of the LHG60 links the devices never really came back.

I thought it had to do with the network loop and did not pay attention. When the loop was discovered and elliminated (someone connected two adjacent network sockets by mistake) all links and devices came immediately back and I could access their interface except from a specific link.

When I try to ping their IP I get a couple of pings and then maybe 10-15 requests timed out and the same things repeats. At the beginning I thought that maybe one of the antennas has died but the strange thing is that BOTH master and slave behave the same way.

Even when pinging the devices from their respective side the same thing happens which leads me to suspect that something else is the underlying cause.

When checking the LED lights on the devices the pattern is equally strange. Upon rebooting the power LED switches on and then the ethernet LED switches on and blinks as expected however as soon as the wireless link is apparently established and the wifi LED is on then the ethernet LED starts blinking really slow instead of the typical fast rate blinking when traffic is going through.

Any suggestions? Or should I RMA them and replace them? I bought these like 6 weeks ago.

This Device only needs 2-3w if this is RF Tower it could be induction to your cables, or different earth potential

Mikrotik is wasting 18 months of advantage on 60 GHZ, is it possible to know if there is any hardware with 5 ghz backup in the close future?

mistry7 · March 18, 2019, 10:17am

Why?
UBNT will deliver such product, and there would be an AP as well, so why ask them here thinks that they know from the beginning of there
60 GHz Productlinie.
Again, Mikrotik Wireless is dead end, they are sleeping!

server8 · March 18, 2019, 10:27am

Because is stupid don’t put a 5 ghz feed in an hardware that has the pcb ready, I can’t uderstand why this leak of 5 ghz backup.

ste · March 18, 2019, 10:30am

LHG60 is great and available (for a while now). It runs ROS which is way better than AirOS. So wrong thread to blame them sleeping. This new gear looks very small. So I guess gain is between WAP 60G and LHG60G. If you need 5GHz Backup use SXT or combine LHG60G with af5xhd using a powerbox pro.

server8 · March 18, 2019, 10:52am

Client side is 3 times hardware and a lot of configuration… for the backhauling is the double and the colocation on the tower is not for free

ste · March 18, 2019, 10:54am

Doing backhaul + backup with one Antenna in one direction is not a good idea anyway.

server8 · March 18, 2019, 1:28pm

Mostly it’s rain backup… OK I 'll wait for ubiquiti

ste · March 18, 2019, 1:37pm

May take a while …

On 60GHz WAP radio PCB, there is place for 5GHz radio chips, but it was never used. Mikrotik appears to be just sleeping, while competition is creeping closer and closer and may beat them at their own 60GHz game…
Hopefully this will be a wakeup call and we will see some new 60GHz gear soon. They must have known about Ubiquity releasing their 60GHz solution for some time.

Next months will tell us more.

if we see new 60GHz radios with real new features and improvements, there is still hope MIkrotik R&D have been actually doing something for past months. Question is how long it will take to get new devices certified and released to the market
if no new devices are announced or they just release minor updated version (let’s make a dish metal and call it a day…) it’s probably not very good sign. At that point all that Mikrotik can do is they can start lowering the prices of existing 60GHz gear when Ubiquity releases their 60GHz hardware, but that would mean they have nothing new and all they can do is to lower prices to stay in the game… not good.

There is more stuff on the road. MT announced to do Terragraph. This is a 60GHz Mesh solution and I guess it will be 802.11ay.

While Terragraph sounds interesting, it certainly can’t replace P2P links (whitepaper says range is about 250m, using small antennas).

ste · March 18, 2019, 6:56pm

The range will depend on the used antennas. PTP links will be part of the mesh. I hope different Vendors will be compatible as Radwin and Cambium has announced terragraph, too.

nobbie · March 18, 2019, 8:10pm

Hej guys, I have 750m PTP link to do and three small 230V wires by the road between these two points. Is it ok to use LHG60 kit ? I don’t need 1Gbps throughput, 300Mbps will be ok. What about rain and snow, I want to sleep well

djvolt · March 18, 2019, 8:19pm

NO NO NO, autostoper have 400mm, NOT 600mm and please DO NOT put people in the wrong place ok?..

aisme · March 18, 2019, 8:41pm

I understand however this is just the roof of the building without any RF tower on it. All the cables going up to the roof are 35-40m Ubiquiti Touch cable. 4 LHG60s doing PTP links. All connected to the same ground. All working fine except this one
