Zigbee and Z-wave could be out as Broadcom’s new chips bet on Bluetooth and Wi-Fi

Broadcom is betting on Wifi/bluetooth to become the connection standard of well...all things. Broadcom’s vision is one that suggests other protocols are either closed or the standard is so open to interpretation (Zigbee) that it might as well be closed.

Broadcom is looking at a future where all devices are on the net and can connect to everything. Smart phones have become the universal controllers of our modern world and the current set of smart devices have zero support for Zigbee or Z-Wave. If Broadcom can develop a chip that will easily replace existing chips or be an easy and cheap addition to exisiting systems then perhaps the concept will manifest.
