The original design was utterly terrible. A low data rate frequency hopper with long packets. Which meant the RF performance was terrible and non state of the art. By design. I think they thought spec'ing low data rate frequency hopper meant automatically low cost, low power. They messed up the low power part by spec'ing a complicated baseband that had everything but the kitchen sink. Basically duplicated the USB spec but then added authentication and encryption on top of it. Which is even more complicated because everything runs over a unreliable frequency hopping rf channel. Frequency hopping messes with a lot of things.
