What are the significant differences between LTE and WiMax? They're
both OFDM, they're both MIMO. I guess that LTE is 4x4 (I don't know)?
Just wondering what the technical challenges might look like.

My understanding was that it was an FPGA and software based platform.
And that PW bought the design from Design Arts Networks so they could

extensions to drivers for an ASIC.
I think the point Patrick is trying to make is Telrad designed their
hardware from the outset to handle both WIMAX and LTE, with WIMAX
coming out first, but same HW being upgradable via SW to LTE. And
that now they have actually done it, which is significant, because
many engineering teams in history have said “it’s a SMOP (small matter
of programming)” and then had to admit defeat and change the hardware.

Purewave claiming SDR because they can add proprietary extensions
seems like Ubiquiti claiming to be SDR because they licensed Atheros
driver code so they could make AirMax.
I always thought SDR meant the signal processing, anything to do with
making sense of the RF, happened in software (FPGA counts!). Ettus
Research's USRP is a example on TX/RX. RTL-SDR USB sticks on the RX only.
E.g. If, in theory, the manufacturer can reprogram it to be a FM radio
(maybe you replace the transciever/amps first though).

Why is it not software defined? Because DAN owned the core WIMAX
software? Purewave claimed to have purchased the rights to make
their own mods, that was one of their claimed advantages over
PMP320. Not sure what Mercury would say now. But don't they have
a proprietary enhanced (but not LTE) version now? I don't see how
they do that if it's not a SDR.
I assume we are talking about the part of Purewave that went to
Mercury, not the part that went to Redline.
If you mean was it designed to do both WIMAX and LTE with just a
different software load, no, they never claimed that AFAIK.

PW is not SDR based
So call their Distributors and tell them to change their
announcements.
Just google Purwave and SDR and you find some.
