Mototrbo is TDMA with 2 time slots. Nexedge is only FDMA! So mototrbo has double channel capacity with only one repeater license....more network with less costs.
You forgot to take bandwidth into account.
Your statement above is regarding a 12.5khz BW channel which is what MotoTRBO is limited
to.
Nexedge is FDMA but it is capable of 6.25Khz channel BW so its a toss up, but as far as
frequency spectrum efficiency is concerned I would give it to Nexedge due to it being
a liitle more flexible as its not limited to 12.5Khz BW channels.
So how much are the nxr-X10 series repeaters?
What's the price diff between nexedge and trbo portables?
No, it's not a toss-up, unless Kenwood sells their 40-45 watt repeaters for $1250 MSRP (which I know they don't do). For $2500 MSPR for a MOTOTRBO repeater, you get two talk paths (two 'virtual' channels). For multiple transmitters, such as in a trunking system, you also need half as many combiner cavities and isolators for the MOTOTRBO system (because of half the number of actual repeaters).
So, the infrastructure cost of a MOTOTRBO repeater system is definitely less than a Nexedge system, given the same number of 'talk paths'.

What's the price diff between nexedge and trbo portables?
That is until the FCC goes narrow band again and requires us all to go to 6.25 and all the TRBO equipment is useless.
At dealer pricing, the TRBO portables are higher. One nice thing with IDAS, is that icom has come out with the F4101 which is half the price of the other models, if you dont need all the extra features. Plus the Nexedge/IDAS equipment is 6.25 already, so if they narrow us up again, its ready.
got the opportunity to demo and drive test a Nexedge 12.5KHz system for a client. One advantage NexEDGE has over TRBO while TRBO is based on DMR, it like all Motorola products, has that nice PROPRIETARY FEATURE issue rendering some incompatibility with other non-Moto subscriber radios (Hytera to be exact).
In my experience the Nexedge audio was outstanding in 12.5KHz, superior error correction than P25. And we had the NX-800 repeater we were using setup for dual mode (analog/digital 12.5KHz) operation to compare. In places where an analog carrier was hard to copy, almost useless- is where the NexEDGE digital came through with almost no artifacts and perfectly intelligibility.
Not to mention, the NexEDGE product lineup seems more affordable than MotoTRBO. I was almost blown away at how cheap the subscriber radios are.
I gather you didn't get a chance to try Nexedge out in 6.25 khz mode? I'd be curious to know how the audio compares in 6.25 khz mode to the 12.5 khz mode.
As to proprietary features, the Hytera has that, too. I'm sure that when a repeater and subscribers are put into their 'psuedo trunking' mode, that a MOTOTRBO subscriber won't work on that system anymore. And I know that Hytera's encryption isn't compatible with MOTOTRBO's encryption. And these features in the Hytera are not part of the DMR standard. So, why are aren't you complaining (or even just pointing out) the fact that Hytera has proprietary features, just like MOTOTRBO?
Also, the subscribers may be less, but last time I heard, the repeaters were quite a bit more, especially since you need two repeaters for every one MOTOTRBO repeater to get the same 'efficiency'. Of course, maybe they've dropped the prices of their repeaters.
