That is how I am configured now (with the exception of using MT for the AP's, but they are just bridging down to the core router). Where we have cabinets I have 493AH's and where we have buildings we have X86 routers.
The bottleneck is on the wireless level/AP's. Just trying to get a good plan formulated that we have an upgrade path that will allow a semi-gradual upgrade without me forklifting all the CPE. With just me an 1 installer, the thought of dead cutting 140 customers would be an absolute nightmare. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Wisp Lists Sent: Thursday, February 07, 2013 7:58 AM To: Mikrotik discussions Subject: Re: [Mikrotik] 2.4Ghz AP upgrade recomendations Hi Robert, We have left our MT on the ground (450g), it is the repeater's router, it does everything but wireless. If you are delinquent it takes care of you, if you require more bandwidth or data that's it's job or if you need to to be stopped in your tracks that's it's job. Now up in the sky is the ubnt AP in "dumb" bridge mode, if you can "authenticate" you are in. We do still have a few bullets with omni's out there, but their days are numbered, the antennas will become hotspots. But we have ubnt rockets with dual-pol omni's or sectoral, depending on the repeater. We hit massive speeds all the time. Check our website for our new "4g" AirMAx speeds. We hit them all the time. But we won't light up a repeater, without a MT450g, it's a must have.
