Alvarion had that as a dream, but was never able to realize it. It was only achieved under the Telrad banner, but yes I do remember some months back more a competing vendor telling people it was impossible to convert from WiMAX to LTE without a hardware change.

And that PW bought the design from Design Arts Networks so they could modify it, as opposed to just licensing the design. Not just adding 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.

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).

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. -----Original Message----- From: Stefan Englhardt Sent: Wednesday, March 04, 2015 12:30 PM To: [email protected]<mailto:[email protected]> Subject: Re: [AFMUG] New feedback (Patrick Leary) 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. ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************ ************************************************************************************ This footnote confirms that this email message has been scanned by PineApp Mail-SeCure for the presence of malicious code, vandals & computer viruses. ************************************************************************************
