Like said I agree on the slow availability of promised products by Mimosa. Two years ago when de ePMP1000 was presented to us in Madrid they already nodded ‘ac’ was ‘on route’ but now 2 years later still not there….
And yes, they surprised us with the ‘elevate’ solution in the meantime but yet again, promised firmware for Mikrotik is still nothing more than just that, a promise….
Mikrotik has shown in the past (and yet again in Milan!) that hardware solutions presented can sometimes take almost a year before they are really available. And If heard on the forum Ubiquity is not so much different. So I’ll guess it is an industry wide theme…. Presenting to be the first with something new but delaying the real delivery to overcome all the setbacks in the production lines and real implementations…
And I do indeed believe that eCambium delivers a good product. The ePMP2000 has some features that are really interesting (like the channel filter).
And comparing different networks is always a bit of a hassle since one has this, the other has that, etc. etc.
One major factor though in migrating smaller WISP networks is the always imminent lack of resources while at the same time trying to keep the resources rich raiders out of your backgarden. So deliver the best quality but try to be clever in the economics….
Hence in regard to the prices some remarks:
You have to do some shopping. Where Cambium has a strict sales policies with protected dealer network, so price are pretty fixed, Mimosa is a bit more easy to bargain for. I found suppliers in Europe that give me some 15-20% better prices than the national supplier. And since I am a profound European I see no reason why I should not shop somewhere else if I can save me some bucks….
Based upon what I pay:
- Mimosa A5c GPS = 570 Euro + antenna 70°/100° = 100€ (carrier class RF elements) => 2x570 + 4x100= TTL 1540€ Or 3xA5c + 6x100= 2.310€ That’s 2.500€ for a full blown 6 sector 150+ clients serving tower. That’s ‘interop’ mode still…..
With 3 A5c’s and 6 sectors and some 150 clients costing me 75€ each (mix of LHG’s, LDF5’s and Dynadish) I have to spend 13.700,- say 14.000€ for a full 150 clients serving tower and everybody should be able to get peak downloads up to 30-40Mbps. This option uses 3 x 40Mhz + 5Mhz band protection = 135Mhz of spectrum.
With eCambium I have three options to do sort of the same:
A. Either use the ePMP 2000 GPS + Smart Antenna option for 4K and with 150 eForce 200 clients I end up spending 19.750.- say 20.000€ This is 6.000€ more but ok, fully sync and 2x40 + 15 = 95Mhz of spectrum use.
B. Use same AP setup but convert existing Mikrotik or Ubnt CPE’s with ePMP elevate software. (25€/ud). That would make 4K + 150x85€ (mix) = 16.750€ say 17.000€. Still some 3K more than the Mimosa option.
C. Instead of the ePMP 2000 use the 1000 but the rest stays the same; You’d save some 1.000€ compared to option A or B. Still more than the Mimosa in ‘interop’ mode.
This is all if you’d compare Mimosa with eCambium and you need to setup a new tower with all new clients. Yes, I agree that on the moment due the lack of a C5c device this is not yet even possible with Mimosa in their full GPS syncd tdma setup.
But as I showed, in ‘interop’ mode this is possible and as I have seen myself, ‘interop’ mode doesn’t necessary mean “poor performance”.
When Mimosa would come in the market with C5c’s, it will be a costly system to fully use in its frequency re-use setup but the capacity will probably outdo eCambium 2 or 3 times…. (But who needs a 200-300Mb plan?)
[I am going to write them their C5/C5c price policy really needs to be overlooked.]
Many of us probably are not thinking of setting up new towers to serve new clients. Most of us are looking to upgrade existing towers to serve the same or more clients from one AP and at the same time crank up our consumer’s plans.
Now the differences are a bit more clear:
With a Mimosa tower as prescribed above you spend 2.5 thousand euros and the clients basically can stay the same (given signals are already good enough.)
To upgrade this tower to eCambium usage the APs costs 4K (or 3K) PLUS 150 elevate licenses makes the investment still 7.750€ (or 1K less).
That’s a difference of magnitude of 5K!
Ok, we have a different network now:
Mimosa is 802.11 csma with RTC/CTS and depending on the clients ‘n’ or ‘ac’.
eCambium is 802.11’n’ tdma with GPS sync so you’d save some spectrum and it comes with beamforming.
If you want the beamforming option to work on the Mimosa also then you have to put 6 x A5c’s plus 6 times MTI 65º 4x4 Mimo 2x dual slant antenna which than will cost 5K€ combined. That is still more than 2.5 thousand euros cheaper than the eCambium option but now no doubt you could serve 6x40=240clients on the tower, still all in interop mode!
As you can see, I have strong confidence in the Mimosa range of product but you have to be a bit smart to find the best and most economical solution. And not every network is the same.
At the same time we still need to see big scale real world developments with both product ranges and now Ignitenet is coming with some new micropop solutions things are getting more interesting by the day (….well, month…! )
