General discussion forum / How Much ACTUAL Bandwidth Needed to support reliable operation
« on: 2013-02-02, 20:28:01 »
Hi All,
I'm hoping to have secured a site on a tall building to put my remote base station and to use this wonderful product. My plan is to get an IC-706MKIIG. Because I want to have the station operational regardless of power conditions for ARES communications, the site I'm trying to get is mostly line-of-sight from my home QTH. I have 2 5GHZ Microtik access points that I used for bridging between 2 buildings a number of years ago. The supply a solid 30Mbps of bandwidth when they are LOS and the firewall is running. A bit faster without a firewall running.
HOWEVER, there is a tree between the building and my condo. The crotch in the tree doesn't have much foliage yet I'm not sure that I can push the 5GHz through it in the summer. So, my backup position is 900Mhz. When examining these systems, the manufacturer says that they pass 1.3Mbps, but from a practical matter, about 984Kbps bi-directionally. With a yagi, these will "burn through" the foliage.
So, my question to the forum is this. Has anyone actually run a test to determine how much bandwidth is actually necessary to have reliable communications? Our manufacturer is recommending 1.5Mbps as a minimum.
If I were to get this awesome location on a 13-story building, I would use the 706 for both HF and VHF/UHF so there could be 2 SIP channels coming back for audio.
***
And for those of you who might need some assistance with networking, firewalls, etc. I'm a computer geek, EE and creative problem solver. I've offered to edit the manual and clean up the English so that it is clearer. Speaking 5 languages, I hope to help out the kind folks in Sweden making the Remote Rig.
Say a prayer for me that I can get back on the air!
