IFeaturesofHAC-LBee/SWirelessModule
HAC-LBee/Sisakindoflowpower wirelessmodulebasedon802.15.4 protocolstack. The
features areshown as follow:
1. Lowpower transmission with100mW 20dBm),and receivingsensitivityis-105dBm
BER=10-2).
2. ISM frequencyband with no require ofapplyingfrequency.Thecarrier frequencyis 2.4GHz.
3. High anti-interferenceand LowBER(Bit errorRate)
Basedon theQuadraturePhaseShiftKeying(QPSK) modulation, thehigh-efficiencyforward
errorcorrection channelencodingtechnologyisusedtoenhance data sresistancetoboth
transientinterferenceandrandominterference.Narrowband interferenceofthesamefrequency
canbesuppressedbyDirectSequence SpreadSpectrum.The16 CRC verifybitscanbeusedto
check mistake.
4. Thetransmittingspeed in theaircan reach upto 250kbps.
5. Transmission Distance
Within thevisiblerange,thereliabletransmission distance is 1000m.
6. Multi-channels
HAC-LBee/Soffers16 channels. Itwill selectthesuitableand reliablecommunication channel
automaticallyaccordingto theuser senvironment.
7. UARTinterface
HAC-LBee/SprovidesaUARTinterface ofTTLlevel.Theparityisno-parity(8N1),and thebaud
ratecan besetbyusers.
8. Lowpower consumption
Thereceivingcurrentisless thanorequalto50mA,and thetransmittingcurrentisless thanor
equalto 160mA.
9. Small sizeand lightweight
10. Byusingmonolithicradio-frequencyintegratedcircuit and single-chipMCU,thetransceivers
haveless peripheralcircuits, higher reliability,andlower failurerate.
11. Offeringmanykinds ofantennaconnectingmethods, suchasPCB antenna,Chipantenna,IPX
antennaconnectingbaseand so on.
12. Itcan meetfortheprotocolofIEEE 802.15.4 for2.4GHz.
