Cambium doesn’t give you much choice: 450b mid or high gain. Yes there’s a 450i SM but it’s hideously expensive, needs 48V POE, and comes only in connectorized or an integrated panel that doesn’t have enough gain. The 450 and 450d SMs are discontinued, unless you’re shopping the used market.
I assume you’re talking about 5 GHz. In 3.65 the SM options are different.

For the most part, customers are decent, but some would need to be re-aligned most likely could probably find 40Mhz if needed. What is your go-to SM for 450M now?

And would you be switching over good, high modulation customers? My observation is get all your subs to 6X or 8X before putting them on a 450m. Also, hard to prove, but I think the antenna gain might be flatter across the 90 degrees with a 450m than with a traditional sector. You lose something like 2 dB, but in the center, not at the edges. I don’t have precise data to substantiate that though. Any chance you could find 40 MHz of spectrum for the 450m?

We have a site that has 3-4 fairly loaded ePMP 2K sectors (30 deg horns). There are a large number of customers in a single 90 degrees. While we could probably upgrade to ePMP 3K to get a bit of a boost, there is still a cost associated in replacing all the CPE to get the full benefit. At this point, we're trying to determine if something like 450M makes sense for this 90 degrees of coverage. The cost is obviously much higher, but I think it may be a better solution in the long run. If we could find a spare 20Mhz, we could run both our existing ePMP radios and the 450M at the same time while we cut subscribers over. Are there other people here who have been in similar situations and have deployed 450M? I realize the performance of the 450M is dependent upon CPE locations, but overall, were you happy with the boost in performance in general? I feel like most people who have upgraded to 450M were already running 450, so you didn't really have to forklift all CPE. If that were the case, I think it would be a no-brainer. Interested in hearing any success (or failure) stories about people who have upgraded to 450M... -- AF mailing list AF@af.afmug.com <mailto:AF@af.afmug.com> http://af.afmug.com/mailman/listinfo/af_af.afmug.com
