ZigBee Wireless Standard Ratified

ductormalef writes "Today, the ZigBee Alliance announced the release (pdf) of version 1.0. ZigBee is a standard for low data-rate (250kbps max) wireless personal area networks (WPANs). It utilizes the IEEE 802.15.4 hardware and MAC layers which utilize frequency bands at 898MHz, 902-928MHz, and 2.4GHz. ZigBee supports mesh networking and claims to be 'wireless control that simply works.' They claim to be a solution to everything from wireless home automation to industrial control."

      The deal is you can't accomplish the same thing with a Bluetooth radio. Bluetooth radios are legacy frequency hoppers. The two major problems they have are poor receiver sensitivity and slow network synchronization times.

      Receive sensitivity matters because half your range is in the last 3dBm. Or better most of you're quality of service is in the last 10-30 db. Bluetooths receiver gain (-70dBm) is horrid as a result of the coding scheme used. Also because Bluetooth is a frequency hopper, once a device powers down it quickly looses synchronization with the network. It can then take a second or two for it to resync when it powers back up. This totally bytes for mice, keyboards and low power sensor networks.

      Zigbee uses a direct sequence spread spectrum radio which is very nizely done. Radios designed around the spec can have high (-100dBm vs -70dBm) receiver sensitivity which translates into longer range and and high quality of service than you can get with Bluetooth. And if the device you are trying to talk to is continually powered up, you can start transmitting information immediately, which is good for sensor networks and battery powered devices.

      Also the reason R&D is dropping on Bluetooth is that the technology was at a dead end from the start. Once you have functional silicon there isn't anything you can to to improve the performance. Bluetooth also is being squeezed from the top by WIFI which gives you literally 100 times the performance at double the cost and Zigbee which does pretty much everything that Bluetooth was supposed to do at a quarter the cost. Granted there are no Zigbee devices out there yet, but hardware development has been proceeding in parallel with the standard itself.

      Finally the NRE cost of using a Zigbee solution will be a fraction of the cost of Bluetooth. That isn't very important for consumer devices which are made by the million, but is very important for industrial devices which are made in the tens of thousands and everything needs to work together for real.

Ericsson (creator or Bluetooth) has disbanded their own team for developing Bluetooth; but that is because there are numerous other manufacturers of Bluetooth chipsets that do the work as well or better than they do it themselves.

      Well Bluetooth has AVRCP. But it is a connected profile, not broadcast.

      It bothers me too that there are so many standards on 2.4GHz, some of which just avoid each other and others interfere, but none of them inter-operate. I think the next generation of standards should all use the same spread-spectrum method (DSS vs. hopping, if that flamewar is ever resolved) and the same frequency-choosing algorithms, and use ultra-wide-band signalling, while still permitting inter-operation of devices at different power levels. The reason there are so many standards now is that to save power you have to cut speed; networking, short-range device communications, and low-speed sensor networks are really different animals. But in low-power devices, capacitors could accumulate power slowly and then transmit short bursts at high power levels, enabling the same speed/power tradeoff without changing the basic symbol rate. And the high-power pulses would achieve longer-distance comms for the same long-term power consumption. But probably all this has already been thought of.

      The available spreading codes for the chosen algorithm could be partitioned into ranges for different power levels, perhaps.

      Still zigbee may just be a worthwhile exception to this general principle, because the power levels are really, really low - like running for years on a single battery.

      Hmm... it would be cool and would probably work in the remote control world if you had an inertial motion sensor that "hinted" to the remote that a human was playing with it. If the remote detected it was being moved, it would get charged up and ready to transmit. When the human hit the button, *bam* -- discharge into the transmitter immediately.

In my mind, this means "quick response time" -- if you press channel up, you expect the channel to go up now, not two seconds from now. (A mute button that took over a second to quiet the annoying Menards' guy would really get on my nerves quickly.)

      Look at his phrase this way: legacy "frequency hoppers". He's saying the hardware that is out there now is frequency hopping, and that it's not a software-controllable thing. Frequency hopping takes a significant amount of time to perform discovery, and that time is not conducive to a remote control that has to respond within less than 330 milliseconds to achieve consumer acceptance. As you pointed out, Bluetooth mice and keyboards have a significant startup time penalty, but that time penalty is the death of "consumer remotes". Remotes don't need to establish "sessions", they're a one-off "change the channel NOW" or "mute the sound NOW", followed by a significant and unpredictable amount of down-time. And unless you have an significant portable source of power, you can't really afford to keep the radios in session just because the consumer might want to change the channel in the next 30 seconds.

However, for all the technical reasons the parent poster mentioned, there really was nothing for them to do in this arena.

It certainly wasn't one of the original design goals, anyway -- it would only ever be a retrofit.

      Bluetooth's stated goal was to be a cable-replacing technology. Zigbee is supposed to be the "low latency" technology. Perhaps if Zigbee was named "Hi-Speed Bluetooth" (so we could all confuse it with "Bluetooth 2.0" :-) it would be less of an issue.

So, even by 2004 numbers, Zigbee will be in less than 1% of new cell phones shipped next year if they hit their target. Bluetooth, on the other hand, ships two million units per week in various devices. Perhaps it "will be big", but you need far stronger numbers to back up your prediction.

      Heile says it'll be "on target for 5 million units"? Your own article reports that he also said "analysts are predicting between 5 million and 50 million Zigbee devices in the first year", which means Zigbee might make the low end of predictions.
