Point to Point Mikrotik

Sunday, December 13th, 2009
Routed or bridged, there are few back haul radios available that can match the Mikrotik RouterOS software for features, tools, flexibility and cost.  With features and flexibility comes complexity and confusion.  I wanted to help dispel some of that confusion with this article.  You may have lots of choices to make, but most of these choices are relatively simple decisions.  And so, brave reader, proceed...

Mikrotik’s True Full Duplex Wireless – NStreme Dual

Sunday, April 19th, 2009
There are numerous full duplex options available on the market today when you go looking for wireless devices.  Most of these devices will cost in the multiple thousands of dollars.  With NStreme Dual, Mikrotik's proprietary FDX protocol, you can build a true full duplex link for under $1000.  This article is a tutorial walkthrough on configuring an NStreme Dual link, along with some helpful hints on how to tweak it.

Using OSPF to create full duplex behaviour for wireless links

Thursday, October 23rd, 2008
One reality that all WISPs face is that all radio communications are half-duplex.  When one end of a link is "speaking", the other end must be "listening".  For many applications, this is sufficient for our purpose.  When a link becomes busy, however, some types of communications are negatively impacted by the delays caused by this behaviour.  Mikrotik RouterOS offers some options to help you alleviate this congestion without breaking the bank. In this article, I will discuss the details for how to configure Mikrotik RouterOS and OSPF to provide a simulated full-duplex link with the added benefit of failover to half-duplex in the event of a single link failure. This idea is taken from an article I wrote on my main website back in November of 2006. (more…)

What opportunities does Mobile IP offer WISPs?

Tuesday, September 23rd, 2008
In my recent article regarding the implementation of a MIP solution with Mikrotik RouterOS clients, I described some of the issues surrounding the a MIP solution as well as some of the solutions.  This article generated quite a bit of response and I wanted to take the time to now offer some business ideas for how this can be useful to WISPs.

Mobile IP? Some thoughts on how to make it happen with Mikrotik RouterOS.

Thursday, September 18th, 2008
It seems to be "all the rage".  Mobile IP.  In reality, mobile IP, describes the ability for a user to move across a network without having to renumber his devices.  This definition holds true even if a user moves from one network to another.  In other words, a user is able to keep his IP address without regard to where his device exists on the internet.  That's not exactly what I'm gonna describe here, but it is a very close approximation. The solution you are about to read is real and tested....names (and IPs) may be changed to protect the innocent... (more…)

Mikrotik router audio alignment script.

Thursday, September 11th, 2008
This helpful script was given to me.  It was sent to me by WISP-Router (http://www.wisp-router.com/).  Casey told me it was sent to them by one of their customers.  It will create a beep that changes frequency as the alignment gets better/worse.  Requires (of course) a MT router with a speaker onboard.
