> Such a thing doesn't exist because it's not in test equipment suppliers interests Test equipment suppliers are MORE than happy to hand you very expensive test equipment on very expensive leases. They're not the bottleneck.

All to produce something which then will require an expensive, complicated dance to get certified with the carriers. However, if you did produce such an open source chip, the Chinese suppliers would definitely jump on it. You just wouldn't make any money.
