ZigBeeis low-power, short-distance wireless standard that great possibilities applications from home automation industrial control.
Market
Research released report calling ZigBee market "sleeping giant," forecasting deployment over million ZigBee devices 2007 million 2008. ZigBee built low-cost, power, low-data-rate wireless networking standard designed monitoring management control applications industrial home markets. (Hence; time lighting appliances, irrigation systems, garage door openers, surveillance cameras more). ZigBee developed serve different applications than Bluetooth technology leads "tremendous optimizations power consumption," according ZigBee Alliance, trade association formed promote standard. According organization, some differentiators from Bluetooth include: Very duty cycle, very long primary battery life Static dynamic star mesh networks, 65,000+ nodes, with latency available Ability remain quiescent long periods without communications Direct Sequence Spread Spectrum allows devices sleep without requirement close synchronization
Potential ZigBee applications include home automation, wireless sensors, interactive toys, smart badges remote controls.

While ZigBee applicable industrial consumer markets, ABI's report suggests that consumer sector will provide "many times revenue most optimistic predictions industry," mature ZigBee market. while industrial buyers will ZigBee ball rolling, ultimately consumer sector will easier vendors enter because technical requirements there less stringent. ZigBee(TM) Alliance, global union companies offering wireless solutions home, commercial industrial applications. This alliance includes companies such Group, Ember Corporation, Freescale Semiconductor, Inc., Honeywell, Mitsubishi Electric, Motorola, Philips, Samsung, Siemens Texas Instruments, Huawei Technologies, Schneider Electric STMicroelectronics ZigBee Alliance Board Directors. Adding original equipment manufacturers (OEM) Alliance well platform providers expands synergy expertise within ZigBee Alliance while allowing better support when comes large scale product introductions. ZigBee already offers largest selection most robust supply chain wireless control technology with compliant platforms. OEMs actively selling end-user products based ZigBee medical, automated meter reading, marine safety home automation markets.
Fundamentals Zigbee Radio
IEEE's 802.15.4, standard defining Zigbee radio, completed 2003. Zigbee radio aimed long battery life, data rate, cost well networks. Zigbee radio includes physical radio hardware layers (Media Access Control). Zigbee Alliance does rest work controlling build interoperable pieces network. couple pieces stack networking security algorithms. network layer enables self-organizing networks along with security. example; while using Zigbee radio remote control garage door opener, proper utilization security algorithms essential prevent hacking code possible trespassing. large commercial application such high rise building where lights HVAC controlled Zigbee network, full encryption used avoid hacking that will result turning lights. Zigbee platform includes 15.4 radio, network layer, security layer, application services layer. Zigbee radio's range vary from meters. Different Zigbee radio networks have ability communicate with each other recognize each other. Another application that utilize Zigbee network golf course watering systems. Using Zigbee network, turn sprinklers certain sections other sections given course. This becomes very important water conservation, similar manner used power conservation. Zigbee Alliance addressed some problems that were encountered Bluetooth Alliance concerning noise interference. Noisy cordless phones, example, utilize 802.11 technology, tends interfere with Bluetooth WLAN applications. Zigbee Alliance addressed interference concerns through applying channels band along with agile frequency hoping that move itself area within band that clear interfering noise. other hand, 802.11 only channels that utilized band, including guard channels.

does support Zigbee Radio Applications?
Increasing demands grow efficiency improvements within industrial control applications well secure features involving wireless applications within consumer electronics have opened venues wireless solutions encompassed within Zigbee Radio Protocol (hence IEEE 802.15.4). Semiconductors primarily focus their development efforts portion well encoding software. Every Zigbee radio utilizes quartz crystal resonator that utilized reference clock generator within transceiver Typical characteristics defining reference crystal resonator are; frequency equal 16MHz 32MHz, stability over industrial temperature range does exceed +/20PPM load capacitance ranges from 12pF 20pF (depends transceiver used). Examples proposed P/Ns;
Model ATS-SM (Crystal HC49/S) +/-20PPM stability 16pF load Examples P/N; R1W22B16T032M00000 R1W22B16T016M00000 Model (5mm crystal resonator) +/-20PPM stability 16pF load Examples P/N; 407F16C032M0000 407F16C016M0000
