Bluetooth is for short range (a room), whereas Wi-Fi & ZigBee are for medium range (a home or a department floor in a company). Next generation Remote controls will do more than just controlling your TV or STB a maximum 10 feet away. ZigBee RF4CE provides long range interoperability (100 feet or more) enabling the TV set and set top box, and associated home automation, power management and security applications, to talk to the home owner anywhere in the home. Bluetooth is good for short-range solutions around the PC or the smart phone, but not for solutions that preferable involve multiple devices throughout the home. The future will show that in the same way Wi-Fi and Bluetooth coexist, ZigBee and Bluetooth will coexist, and creating contention is just wasting time. Companies with vision have decided for ZigBee RF4CE. This includes companies like Sony, Comcast, Samsung, NEC, LG, Philips, Toshiba, Texas Instruments, NXP, Atmel, Freescale, etc. all RF4CE steering committee members

I am interested in any other comments onm RF4CE versis BLE for TV remotes. Looks like quite a battle going on here.

Power utilization is important, but we also have to clearly understand the usage model. If this is primarily a replacement for IR remote controls (long overdue, IMHO) then we have high emphasis on standby power. If there is going to be media streaming (improbable but possible) then we are concerned with block transfer efficiency. Also, please don't make the same stupid short-sighted mistake by maintaining proprietary interfaces. Give me an interface which lets me really integrate these devices instead of having to work around these silly garden walls. Larry M.

There many new energy harvesting products. Is BT 4.0 going to incorporate any of this? Can BT product incorporate energy harvesting procut to last perpetually?

What matters more is not the technology, rather which one the manufacturers will adopt. RF4CE is a good remote solution, but if it's not adopted it's useless. Same for BT. It's looking like BLE may be the way manufacturers are headed. Both BLE and RF4CE are suited for remote use, very little difference.

Yes.It is completely new stack for BLE including applications. Many applications for BLE are in draft phase now. One limitation i can see is BLE does not support voice.

The high idle power mode was a big problem with Bluetooth. BLE looks like a new protocol stack altogether. Right?

There is at least one order of magnitude difference in power consumption between Bluetooth and Zigbee. The latter is more suitable for low data-rate control applications.

ANT+ power consumption is almost same as BLE. All other PAN technologies are more power hungry than BLE

No power consumption issue with BT4.0(BLE).BLE transmits quickly and listens quickly.50x faster to send data than traditional BT.Turned off 99.9% of the time.Ble is 0.1x power consumption of traditional BT. So a coin cell battery can with stand for years.
