A lot of the suits brought against states, counties, or cities due to the other company winning the bid were based on the contract being written to clearly favor one vendor over another. And a public safety contract should be written to be totally neutral in that respect.
Motorola sued the State of FL and backed out of the contract they WON because they found the booby trap: The buried "state may terminate for convenience" clause. Not for CAUSE, not for failure to perform or meet progress schedules, but for CONVENIENCE. Which means "You won but we can make you build out the sites and then give it all to your competitor" and I suspect that would have happened.
Contracts have been written to require equipment that one vendor doesn't make. Such as when M/A-Com didn't offer a hand held control head option, the State of Fl contract stipulated that they must be offered. (Long ago, previous contract.) And it was written into the same contract, "radios shall not use ramp buttons for volume or channel select functions" when GE/whatever was using ramp buttons on their most common public safety radio types.
I'd like for there to be a process where all public safety contracts and proposals are run through an absolutely neutral consulting agency that is fully informed on the product lines, capabilities, equipment, and services of all vendors and ensures that the contract/proposal is written in a manner that makes sense, totally brand neutral, and written to specify a system that will work in engineering terms. To include regional terrain and infrastructure surveys so that the RF plan gives full coverage as called for by the needs of the agency.
Motorola claimed they could make the State of FL system work to coverage specs with about 30 fewer sites than the Harris proposal, stating that they could do it with "superior technology". But we know how that would work out. They'd have to add more sites after the fact, because RF is RF and neither Motorola nor Harris can break the laws of physics...though both are willing to break certain laws if they can make sure nobody notices for a while. Bidding for contracts worth hundreds of millions of dollars or even billions becomes a DIRTY business.
