We stick to the 17dBm output of the RADIO, but we do use 10dBi sectors...

Unless you've got 7dB loss in the feedline between the radio and the sector antenna at your operating frequency, you're over the limit and should turn the radio output down appropriately. 17dBm + 10dBi = 27dBm EIRP, or 501.19mW EIRP.

You can subtract any calculated or measured loss in the feedline, up to but not including any pigtail that is attached permanently to an antenna. The gain figures published by antenna suppliers usually cover any losses in such pigtails if they are permanent fixtures, e.g. part of the antenna construction. 35m of LMR-400 between radio and antenna would give you that 7dB loss. 5.8m of RG-58C will give about the same loss.

Alright people, I have spoken Miro support, and I believe I owe you all a apology, diebaas, richard, and everyone else, sorry.

The results are in. Yes, its not legal, BUT (YAY!) As long as I dont interfere with Telkom, Sentec, IBurst, and the rest, as well as the goverment channels, and other users, it ok, or atleast Kwasi-legal, I did a scan, and I found about 4 other AP's in the 10km link between me and the GWI tower, luckily, I'm quite a few channels away from them, andm GWI specifies the Channels, the bridge changes to whatever the tower is, so frequencies are not my problem. The reason for the massive output power on my side, is that I'm connecting on the side of a sector.... so therefore I have to make up with a lot of tx power, and a small MTU, in order to reduce packet loss.

Here's the good news for all of you, I'm switching over to Mikrotik at the end of the month, with a 100mw/200mw card, and the same grid. Here's the catch, GWI is licensing a few frequencies, and as I've said before the bridge connected to whatever channel the tower is on.

and, another thing, I'm quite hight above the rest of the people. I live on a mountain, and I was told, as long as I dont go connecting to private AP's, or APs I dont have authorization for, I should be in the clear.

No problem but in due future please double check your facts.

Didn't mean to offend you

yes of course - and what about the connectors, lightning arrestors and pigtails that are not part of the antenna?

 

[Trybble]

If they're all in the signal path between the radio's output connector and the antenna, their loss can and should be factored in. Having said that, if you're using connectors and lightning arrestors that exhibit more than a small fraction of a dB loss, you really need to reconsider where you're buying your equipment from.

Telegartner and Suhner connectors are worthy. I wouldn't trust lesser connectors simply from a noise perspective, never mind higher losses. Oh, and I wouldn't use LMR-400 at microwave frequencies either. One exuberant installation bloke later and that aluminium core can fracture, making yet another noise source.

Here's one that, if solved, I will really be indebted to you guys, as you all know, I'm putting out massive power.... so, Connection is O.K.... although I have dialed down the db's....

Now, I'm getting full speed from the GWISA tower.... that is, downstream 192k. Which would mean upstream should be 96k..... currently, i'm not getting more than 15kbits.....


I phoned.... and spoke to some guy, which honestly, doesnt know anything about IT.... yes, Web Intact, I know the guys at GWI are trained, but this guy, should work in Sales or something, he started the whole noob thing about, have you checked you connections, have you done a virus scan, $hit like that. And the more I keep telling him the connection and speed is fine, its only upstream, the more he goes on about patching XP.....

Anyway, guys, that aside. GWI is good.

If I send small emails.... it will send. But if I try to upload larger emails, more than 100kbs, the connection will timeout. I've tried POP with SSL to Google, and http upload.

Downstreaming seems 100% OK, and my connection is stable... and bandwidth tests, seem to agree. Downstream 192.
Upstream 15. HELP HELP HELP.... lol


-Thanks guys

Lesson #1 in calling support:

If you call after hours, you'll get any one of a whole bunch of guys who can help you set up your email, reboot your computer or call higher level guys in the case of network failures.

If you have a problem bigger than that, it's advisable to call during office hours, or send an email to [email protected]
The number of times I've said this here in this very thread could probably halve the number of posts...

Your problem is packet loss.

Do the following test:
Click 'Start'
Click 'run'
Type 'cmd'
In the black window that appears, type:

ping www.gwisa.com -t -l 1400

That's ping[space]www.gwisa.com[space]minus tee[space] minus el[space]1400

If you get timeouts, it's 99% your connection to the tower.

'can' and 'should be' are you saying it's optional?

Aluminium core????? Where oh where do you buy your LMR400?

Oh, and are you looking for a job or something - or trying to sell equipment?

I know I'm getting packet loss. GWI says MTU 1492. I get quite a lot of packet loss, going down to below 1000, gets a lot better, but, increases load of the overall network (tower & my equipment).

Any Ideas on what I can do? As you all know I've got the grid, esc esc.... and putting out over 50db's of power. Which, like i've said before, will be replaced soon....


MTU 1400.... every fourth packet goes bye-bye

 

[kwaggawerner]

....and now, not 3 minutes later, its much more stable...... its like the wind blows away the signal.... lol







..... and back to packet loss.....

Wrong MTU - GWI says 1480... anything bigger will get resized and you'll have iffy performance.

Send an email to [email protected] with your street address and SSID you connect to.
There's nothing more you can do until we can determine if you are maybe (probably) connecting to the back of a sector. With such a big grid, you could pick up a signal from any side, but the sector will never see you properly.

btw - what ping time do you get to the tower with 64 or 32 byte pings? You should get <20ms

Oh, and are you looking for a job or something - or trying to sell equipment?

"Can be" if you have the actual figures otherwise you could end up underestimating your losses and run fractionally lower power. "Should be" is self-explanatory.

Times Microwave LMR-400 has a 2.74mm diameter copper-clad aluminium core - take a look sometime - which is why it is an exceptionally bad idea to bend it sharply. T-M say that the minimum bend radius is 1", but I can tell you from personal experience that if you do that it's best to not try and straighten it again afterwards. I prefer to play it safe and keep to a 6" minimum bend radius if I'm using that cable. Heliax is a much safer bet overall.

No, not looking for a job - got one, thanks - and I've no interest whatsoever in selling any equipment at all. If you can point me in the direction of a nice 2.4GHz masthead receive preamp with a decent noise figure I'd be interested, though. Feedline and connector losses have this nasty habit of not caring in which direction the signal is flowing.

I remember in your previous posts you said to not block ICMP from wan, well I have disabled it, a few days ago already..... and although at first, it appeared that my pppoe was more stable, but then a day or two later it happend again, and setting the MTU way down did help..... marginally.

and.... to be honest, I think I'm losing it.... my pppoe connection was dead for almost 70 minutes..... and I couldnt get it working, so I decided to type a email to GWI requesting support, on my N95 (for those of you who have one, or have seen one, will know it has a very small keyboard)..... I typed a long email, considering it was on a phone, and then when I wanted to send it, MTN GPRS/3G was down...... phuck. Now, the GMAIL app, when there's no connection at the time of sending, it will crash/quit.


Guys..... please, help. I dont know about you guys, but I'm rapidly beginning to hate IT...... and, I havent even really started.... 7 years experience, and now I'm studying.... phuck!


Come on guys!!! Motivation!!

Next time I see some T-M I'll look - but thanks for the tip, I suppose.
If I ever see anyone working for me bending any coax cable sharply, they'll get a *sharp* clip from me....
Heliax is great, sure - virtually bend proof, and therefore idiot proof. Also a LOT more expensive...

If you can point me in the direction of a nice 2.4GHz masthead receive preamp with a decent noise figure I'd be interested, though. Feedline and connector losses have this nasty habit of not caring in which direction the signal is flowing.

A simple solution would be to use separate rx/tx paths and put any suitable amp in-line...

You know - maybe you should start your own thread actually... seems like you'd be more suited to a technical discussion somewhere, what with all these specs at your fingertips and all...

 

[kwaggawerner]

-----Resolution----> for me that is.

I've been in contact with GWISA all-day..... my phone bill ain't gonna like me....

The Verdict:

I've spoken to the manager of GWISA, Neil, he made some calls and he has established that I'm connecting to the side of one of their sectors.

Therefore, I will no longer be able to be a client of GWI.

So, I guess, I bid you guys thanks for the help, and farewell....

Wow, for someone representing a company on here(as you clearly are) I would think you would have a better attitude. Just personally I know that customer service dictates that "the customer is always right." So far the only thing i have seen you do is to belittle the opinions and attempts to find help of new clients and prospective clients.
On a whole I would definately not bother with your services even if they were available in my area. Im sure you have someone dealing with customer service who has a better attitude than you do, I would recommend you rather get them to deal with posts on this BB

@kwaggawerner

I'm sorry we couldn't resolve this problem, but it was fairly evidnet from the outset that the signal just wasn't up to scratch to service you reliably, especially on the uplink. Your name has been added to our sales database, and when the coverage improves in your area you will be contacted to see if you are still interested.

You may be right as far as my attitude goes, I am in technical & not PR.
I always try my best to help people with problems, and don't ignore anyone who does have a genuine issue. If I can't resolve it here, I direct it to someone who can.

This poster, however is not a client with problems, but merely a person who seems to want to display his abundant technical knowledge in an inappropriate place. As far as my Internet forum experience goes, this is not good etiquette.

This thread was originally started by a client commenting on our product & service. It's not the right place to take up space going on about the best way to do put up a highsite.

I hope so, because I'm having tremendous lag issues in Yahoo games, Pogo games, Xbox 360 gaming and Audio streaming from Shoutcast.com, I sent an e-mail to support and spoke to an individual there who had been very helpful with my e-mail the first time around, and it seemed to work for four days then suddenly it all went pear shaped after that. I thought perhaps they changed the settings back to the original form, and sent another e-mail twice but I haven't gotten a response yet and it's over a week perhaps it was due to a problem.

Could this issue be part of the reason that it seemed to be back to the same issue of time out on the shoutcast stream? along with the "unable to connect to Yahoo games, you are either behind a firewall etc..." and the Pogo games error that states something of the similar nature after freezing for 15 minutes and timing out? I know I am behind a firewall...lol..seems to be the general response everytime I say that, but I was able to connect to these games without err for several months, it just seems to have developed recently.
