Radio Board Block Summary3.1 IntroductionThis section introduces the blocks of the BRD4186C Radio Board.3.2 Radio Board Block DiagramThe block diagram of the BRD4186C Radio Board is shown in the figure below.Figure 3.1. BRD4186C Block Diagram3.3 Radio Board Block Description3.3.1 Wireless MCUThe BRD4186C Radio Board incorporates an EFR32MG24B210F1536IM48 Wireless System-on-Chip featuring 32-bit Cortex®-M33 core, 1536 kB of flash memory, 256 kB of RAM, and a 2.4 GHz band transceiver with output power up to 10 dBm. For additional infor-mation on the EFR32MG24B210F1536IM48, refer to the EFR32MG24 data sheet.3.3.2 LF Crystal Oscillator (LFXO)The BRD4186C Radio Board has a 32.768 kHz crystal mounted. For details regarding the crystal configuration, refer to application note AN0016.2: Oscillator Design Considerations.3.3.3 HF Crystal Oscillator (HFXO)The BRD4186C Radio Board has a 39 MHz crystal mounted. For details regarding the crystal configuration, refer to application note AN0016.2: Oscillator Design Considerations.3.3.4 Matching Network for 2.4 GHzThe BRD4186C Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz RF input/output of the EFR32MG24 to the one on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF perform-ance and current consumption with 10 dBm output power.For a detailed description of the matching network, see section 4.2.1 2.4 GHz RF Matching Description.3.3.5 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added a UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default, the output of the matching network is connected to the printed inverted-F antenna by a series 0 Ohm resistor. To support conducted measurements, or the connection of an external antenna, the option to connect the output to the UFL connector is available. If using this option, move the series 0 Ohm resistor to the antenna to the series resistor to the UFL connector (see section 4.2.1 2.4 GHz RF Matching Description for further details). On the layout, the footprints of these two resistors have overlapping pads to prevent simultaneous connection of the antenna and the UFL connector.3.3.6 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the BRD4186C Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32MG24B210F1536IM48 and the connectors, refer to section 2.2 Radio Board Connector Pin Associations.3.3.7 Inverted-F AntennaThe BRD4186C Radio Board includes a printed inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz band.For a detailed description of the antenna, see section 4.4 Inverted-F Antenna.3.3.8 Serial FlashThe BRD4186C Radio Board is equipped with an 8 Mbit Macronix MX25R SPI flash that is connected directly to the EFR32MG24 to support over-the-air (OTA) updates. For additional information on the pin mapping, see the BRD4186C schematic.3.3.9 Serial EEPROMThe BRD4186C Radio Board is equipped with a serial I2C EEPROM for board identification and to store additional board-related infor-mation.4. RF Section4.1 IntroductionThis section gives a short introduction to the RF section of the BRD4186C Radio Board.4.2 RF Section SchematicBRD4186C Radio Board RF section schematic is shown in the following figure.2.4 GHz Matching Path SelectionInverted-F AntennaAntenna Tuning High Frequency Figure 4.1. BRD4186C RF Section Schematic4.2.1 2.4 GHz RF Matching DescriptionThe 2.4 GHz RF matching connects the 2G4RF1 pin to the on-board printed IFA. The component values were optimized for the 2.4 GHz band RF performance and current consumption with the targeted 10 dBm output power.The matching network consists of a five-element impedance matching and harmonic filter circuitry and a DC blocking capacitor (not required for the 20 dBm part).For conducted measurements, the matching network output can also be connected to the UFL connector by removing the series R1resistor (0 Ohm) between the antenna and the matching network and mounting it to the R2 resistor position between the matching net-work and the UFL connector.4.3 Bill of Materials for the 2.4 GHz Matching NetworkThe bill of materials for the BRD4186C Radio Board 2.4 GHz matching network is shown in the following table.Table 4.1. Bill of Materials for the BRD4186C 2.4 GHz RF Matching Network4.4 Inverted-F AntennaThe BRD4186C Radio Board includes an on-board, printed inverted-F antenna, tuned for the 2.4 GHz band. Due to the design restric-tions of the radio board, the input of the antenna and the output of the matching network can't be placed directly next to each other. Therefore, a 50 Ohm transmission line was necessary to connect them.The resulting impedance that is presented to the matching network output is shown in the following figure. During the measurement, the BRD4186C Radio Board was attached to a Wireless Starter Kit Mainboard.As shown in the figure, the antenna impedace (blue curve) is close to 50 Ohm in the entire 2.4 GHz band, and the reflection (red curve) is under -10 dB.Figure 4.2. Impedance and Reflection of the Inverted-F Antenna of the BRD4186C Board Measured from the Matching Output5.

BRD4186C Bottom ViewMechanical DetailsEMC Compliance 6. EMC Compliance6.1 IntroductionBRD4186C Radio Board fundamental and harmonic levels compliance is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2476.2 EMC Regulations for 2.4 GHz6.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328, the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain, the specific limit is -30 dBm EIRP.6.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 W (30 dBm) in the 2400-2483.5 MHz band. For spurious emissions, the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands, the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic, it is defined as 0.5 mV/m at 3 m distance, which equals to -41.2 dBm in EIRP.If operating in the 2400-2483.5 MHz band, the 2nd, 3rd, and 5th harmonics can fall into restricted bands. As a result, for those harmon-ics the -41.2 dBm limit should be applied. For the 4th harmonic, the -20 dBc limit should be applied.6.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. In addition, Silicon Labs applies the same restrictions to the conducted spec-trum. By doing so, compliance with the radiated limits can be estimated based on the conducted measurement by assuming the use of an antenna with 0 dB gain at the fundamental and the harmonic frequencies.The overall applied limits are shown in the table below. For the harmonics that fall into the FCC restricted bands, the FCC 15.209 limit is applied. ETSI EN 300-328 limit is applied for the rest.Table 6.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band7. RF Performance7.1 Conducted Power MeasurementsDuring measurements, the BRD4186C Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the radio board (VMCU) was 3.3 V and for the power amlifier (PAVDD), it was 1.8 V.7.1.1 Conducted Power Measurements with Unmodulated CarrierThe transceiver was operated in unmodulated carrier transmission mode. The output power of the radio was set to 10 dBm. The typical output spectrum is shown in the following figure.Figure 7.1. Typical Output Spectrum of the BRD4186C; PAVDD = 1.8 VAs shown in the figure, the fundamental is 10 dBm and all of the unwanted emissions are under the -41.2 dBm limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a spectrum analyzer through an SMA conversion adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately 0.3 dB insertion loss.7.1.2 Conducted Power Measurements with Modulated CarrierDepending on the applied modulation scheme and the spectrum analyzer settings specified by the relevant EMC regulations, the meas-ured power levels are usually lower compared to the results with unmodulated carrier. These differences are measured and used as relaxation factors on the results of the radiated measurement performed with unmodulated carrier. This way, the radiated compliance with modulated transmission can be evaluated.In this case, both the ETSI EN 300-328 and the FCC 15.247 regulations define the following spectrum analyzer settings for measuring the unwanted emissions above 1 GHz:•Detector: Average•RBW: 1 MHzThe table below shows the measured differences for the supported modulation schemes.Table 7.1. Measured Relaxation Factors for the Supported Modulation SchemesAs shown, the BLE 125 Kb/s coded modulation scheme has the lowest relaxation factors. These values will be used as the worst case relaxarion factors for the radiated measurements.7.2 Radiated Power MeasurementsDuring measurements, the BRD4186C Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the radio board was 3.3 V, for the power amlifier (PAVDD) it was 1.8 V. The radiated power was measured in an antenna chamber by rotating the board 360 degrees with horizontal and vertical reference antenna polarizations in the XY, XZ, and YZ cuts. The measurement planes are illustrated in the figure below.XZYFigure 7.2. Illustration of Reference Planes with a Radio BoardNote: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also, the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.7.2.1 Maximum Radiated Power MeasurementsFor the transmitter antenna, the on-board printed inverted-F antenna of the BRD4186C Radio Board was used (the R1 resistor was mounted). The supply for the RF section (RFVDD) and the 2.4 GHz power amplifier (PAVDD) was 1.8 V provided by the on-chip DC-DC converter; for details, see the BRD4186C schematic. The transceiver was operated in unmodulated carrier transmission mode. The output power of the radio was set to 10 dBm based on the conducted measurement.The results are shown in the tables below. The correction factors are applied based on the BLE 125 Kb/s coded modulation, shown in section 7.1.2 Conducted Power Measurements with Modulated Carrier . For the rest of the supported modulation schemes, the correction factors are larger, thus the related calculated margins would be higher compared to the ones shown in the table below. Thus,the margins below can be considered as worst case margins.Table 7.2. Maximums of the Measured Radiated Powers in EIRP [dBm] and the Calculated Modulated Margins in [dB] with theWireless Starter Kit Mainboard; PAVDD = 1.8 VAs shown in the table, with 10 dBm output power, the radiated power of the fundamental is higher than 10 dBm due to the high antenna gain. The 3rd harmonic is very close to the limit with the Wireless Starter Kit Mainboard in case of the unmodulated carrier transmis-sion. But with the relaxation of the supported modulation schemes, the margin is at least 5.1 dB.7.2.2 Antenna Pattern MeasurementsThe measured normalized antenna patterns are shown in the following figures.180°-35-30-25-20180°-35-30180°-35-30-25Figure 7.3. Normalized Antenna Pattern of the BRD4186C with the Wireless Starter Kit MainboardEMC Compliance Recommendations 8. EMC Compliance Recommendations8.1 Recommendations for 2.4 GHz ETSI EN 300-328 ComplianceAs shown in section 7.2 Radiated Power Measurements, the power of the BRD4186C fundamental with 10 dBm output is compliant with the 20 dBm limit of the ETSI EN 300-328 regulation. With the supported modulation schemes, the harmonics are also compliant with the relevant limits. Although the BRD4186C Radio Board has an option for mounting a shielding can, it is not required for compli-ance.8.2 Recommendations for 2.4 GHz FCC 15.247 ComplianceAs shown in section 7.2 Radiated Power Measurements, the power of the BRD4186C fundamental with 10 dBm output is compliant with the 30 dBm limit of the FCC 15.247 regulation. With the supported modulation schemes, the harmonics are also compliant with the relevant limits. Although the BRD4186C Radio Board has an option for mounting a shielding can, it is not required for compliance.9.

IntroductionThe EFR32 Mighty Gecko Radio Boards provide a development platform (together with the Wireless Starter Kit Mainboard) for the Silicon Labs EFR32 Mighty Gecko Wireless System on Chips and serve as reference designs for the matching network of the RF inter-face.The BRD4161A Radio Board is designed to operate in the 2400-2483.5 MHz band with the RF matching network optimized to operate with 19 dBm output power.To develop and/or evaluate the EFR32 Mighty Gecko, the BRD4161A Radio Board can be connected to the Wireless Starter Kit Main-board to get access to display, buttons and additional features from Expansion Boards and also to evaluate the performance of the RF interface.2.

Connected. Energy-friendly.Rev. 1.00 | 33.3.4 Matching Network for 2.4 GHzThe BRD4161A Radio Board incorporates a 2.4 GHz matching network which connects the 2.4 GHz TRX pin of the EFR32MG12 to the one on-board printed Inverted-F antenna. The component values were optimized for the 2.4 GHz band RF performace and current con-sumption with 19 dBm output power.For detailed description of the matching network, see Chapter 4.2.1 Description of the 2.4 GHz RF Matching.3.3.5 Inverted-F AntennaThe BRD4161A Radio Board includes a printed Inverted-F antenna (IFA) tuned to have close to 50 Ohm impedance at the 2.4 GHz band.For detailed description of the antenna see Chapter 4.5 Inverted-F Antenna.3.3.6 UFL ConnectorTo be able to perform conducted measurements, Silicon Labs added an UFL connector to the Radio Board. The connector allows an external 50 Ohm cable or antenna to be connected during design verification or testing.Note: By default the output of the matching network is connected to the printed Inverted-F antenna by a series component. It can be connected to the UFL connector as well through a series 0 Ohm resistor which is not mounted by default. For conducted measurements through the UFL connector the series component to the antenna should be removed and the 0 Ohm resistor should be mounted (see Chapter 4.2 Schematic of the RF Matching Network for further details).3.3.7 Radio Board ConnectorsTwo dual-row, 0.05” pitch polarized connectors make up the EFR32MG Radio Board interface to the Wireless Starter Kit Mainboard. For more information on the pin mapping between the EFR32MG12P432F1024GL125 and the Radio Board Connector, refer to Chapter 2.2 Radio Board Connector Pin Associations.3.3.8 Capacitive Touch SliderThe touch slider (T2) utilizes the capacitive touch capability of the Capacitance Sense Module of the EFR32MG12. The slider interpo-lates 4 separate pads to find the exact position of a finger.The figure below shows the pin mapping of the touch slider to the Wireless SoC.Wireless SoCFigure 3.2.

RF Section4.1 IntroductionThis section gives a short introduction to the RF section of the BRD4161A.4.2 Schematic of the RF Matching NetworkThe schematic of the RF section of the BRD4161A Radio Board is shown in the following figure.2.4 GHz Matching 2.4 GHz RF OutputSelection & Inverted-F AntennaFigure 4.1. Schematic of the RF Section of the BRD4161A4.2.1 Description of the 2.4 GHz RF MatchingThe 2.4 GHz matching connects the 2G4RF_IOP pin to the on-board printed Inverted-F Antenna. The 2G4RF_ION pin is connected to ground. For higher output powers (13 dBm and above), besides the impedance matching circuitry, it is recommended to use additional harmonic filtering as well at the RF output. The targeted output power of the BRD4161A board is 19 dBm. Therefore, the RF output of the IC is connected to the antenna through a four-element impedance matching and harmonic filter circuitry.For conducted measurements the output of the matching network can also be connected to the UFL connector by removing the series R1 component between the antenna and the output of the matching and adding a 0 Ohm resistor to the R2 resistor position between the output of the matching and the UFL connector.4.3 RF Section Power SupplyOn the BRD4161A Radio Board the power supply pins of the RF section (RFVDD, PAVDD) are directly connected to the output of the on-chip DC-DC converter. This way, by default, the DC-DC converter provides 1.8 V for the entire RF section (for details, see the sche-matic of the BRD4161A).4.4 Bill of Materials for the 2.4 GHz MatchingThe Bill of Materials of the 2.4 GHz matching network of the BRD4161A Radio Board is shown in the following table.| Smart. Connected. Energy-friendly.Rev. 1.00 | 5Table 4.1. Bill of Materials for the BRD4161A 2.4GHz RF Matching Network4.5 Inverted-F AntennaThe BRD4161A Radio Board includes an on-board printed Inverted-F Antenna tuned for the 2.4 GHz band. Due to the design restric-tions of the Radio Board, the input of the antenna and the output of the matching network can't be placed directly next to each other. As a result, a 50 Ohm transmission line was necessary to connect them. With the actual line length the impedance of the antenna at the double-harmonic frequency is transformed closer to a "critical load impedance range" resulting in the radiated level of the harmonic increases.To reduce the harmonic radiation a tuning component was used between the matching network output and the antenna input. For the actual Radio Board design (with the actual transmission line length) a small value inductor was used (instead of the R1 resistor with value of 1.8 nH) to transform the impedance at the double-frequency harmonic away from the critical region while keeping the impe-dance at the funamental close to 50 Ohm. With this the suppression of the radiated double-frequency harmonic increases by approxi-mately 3-4 dB. The resulting impedance and reflection measured at the output of the matcing network are shown in the following figure. As it can be observed the impedance is close to 50 Ohm (the reflection is better than -10 dB) for the entire 2.4 GHz band.Figure 4.2. Impedance and Reflection of the Inverted-F Antenna of the BRD4161A Board Measured from the Matching Output Note: The same value and type of 1.8 nH inductor was used as the one in the matching network (L1). | Smart.

BRD4161A Bottom ViewMechanical DetailsRev. 1.00 | 7EMC Compliance 6. EMC Compliance6.1 IntroductionCompliance of the fundamental and harmonic levels is tested against the following standards:• 2.4 GHz:•ETSI EN 300-328•FCC 15.2476.2 EMC Regulations for 2.4 GHz6.2.1 ETSI EN 300-328 Emission Limits for the 2400-2483.5 MHz BandBased on ETSI EN 300-328 the allowed maximum fundamental power for the 2400-2483.5 MHz band is 20 dBm EIRP. For the unwan-ted emissions in the 1 GHz to 12.75 GHz domain the specified limit is -30 dBm EIRP.6.2.2 FCC15.247 Emission Limits for the 2400-2483.5 MHz BandFCC 15.247 allows conducted output power up to 1 Watt (30 dBm) in the 2400-2483.5 MHz band. For spurious emmissions the limit is -20 dBc based on either conducted or radiated measurement, if the emission is not in a restricted band. The restricted bands are speci-fied in FCC 15.205. In these bands the spurious emission levels must meet the levels set out in FCC 15.209. In the range from 960 MHz to the frequency of the 5th harmonic it is defined as 0.5 mV/m at 3 m distance (equals to -41.2 dBm in EIRP).Additionally, for spurious frequencies above 1 GHz, FCC 15.35 allows duty-cycle relaxation to the regulatory limits. For the EmberZNet PRO the relaxation is 3.6 dB. Therefore, the -41.2 dBm limit can be modified to -37.6 dBm.If operating in the 2400-2483.5 MHz band the 2nd, 3rd and 5th harmonics can fall into restricted bands. As a result, for those the -37.6 dBm limit should be applied. For the 4th harmonic the -20 dBc limit should be applied.6.2.3 Applied Emission Limits for the 2.4 GHz BandThe above ETSI limits are applied both for conducted and radiated measurements.The FCC restricted band limits are radiated limits only. Besides that, Silicon Labs applies those to the conducted spectrum i.e., it is assumed that, in case of a custom board, an antenna is used which has 0 dB gain at the fundamental and the harmonic frequencies. In that theoretical case, based on the conducted measurement, the compliance with the radiated limits can be estimated.The overall applied limits are shown in the table below.Table 6.1. Applied Limits for Spurious Emissions for the 2.4 GHz Band | Smart. Connected. Energy-friendly.Rev. 1.00 | 87. RF Performance7.1 Conducted Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V.7.1.1 Conducted Measurements in the 2.4 GHz bandThe BRD4161A board was connected directly to a Spectrum Analyzer through its UFL connector (the R1 component was removed and a 0 Ohm resistor was soldered to the R2 resistor position). During measurements, the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm.The typical output spectrum is shown in the following figure.Figure 7.1. Typical Output Spectrum of the BRD4161AAs it can be observed, the fundamental is slightly lower than 19 dBm limit and the strongest unwanted emission is the double-frequency harmonic and it is under the -37.6 dBm applied limit.Note: The conducted measurement is performed by connecting the on-board UFL connector to a Spectrum Analyzer through an SMA Conversion Adapter (P/N: HRMJ-U.FLP(40)). This connection itself introduces approximately 0.3 dB insertion loss.RF PerformanceRev. 1.00 | 97.2 Radiated Power MeasurementsDuring measurements, the EFR32MG Radio Board was attached to a Wireless Starter Kit Mainboard which was supplied by USB. The voltage supply for the Radio Board was 3.3 V. The radiated power was measured in an antenna chamber by rotating the DUT 360degrees with horizontal and vertical reference antenna polarizations in the XY , XZ and YZ cuts. The measurement axes are shown inthe figure below.Figure 7.2. DUT: Radio Board with the Wireless Starter Kit Mainboard (Illustration)Note: The radiated measurement results presented in this document were recorded in an unlicensed antenna chamber. Also the radi-ated power levels may change depending on the actual application (PCB size, used antenna, and so on). Therefore, the absolute levels and margins of the final application are recommended to be verified in a licensed EMC testhouse.7.2.1 Radiated Measurements in the 2.4 GHz bandFor the transmitter antenna the on-board printed Inverted-F antenna of the BRD4161A board was used (the R1 component was moun-ted). During measurements, the board was attached to a Wireless Starter Kit Mainboard (BRD4001 (Rev. A02) ) which was supplied through USB. During the measurements the voltage supply for the board was 3.3 V provided by the mainboard. The supply for the radio (RFVDD) was 1.8 V provided by the on-chip DC-DC converter, the supply for the power amplifier (PAVDD) was 3.3 V (for details, see the schematic of the BRD4161A). The transceiver was operated in continuous carrier transmission mode. The output power of the radio was set to 19 dBm based on the conducted measurement.The results are shown in the table below.Table 7.1. Maximums of the measured radiated powers in EIRP [dBm]As it can be observed, thanks to the high gain of the Inverted-F antenna, the level of the fundamental is higher than 19 dBm. The stron-gest harmonic is the double-frequency one and thanks to the additional suppression provided by the instead of the R1 resistor its level is under -50 dBm.RF PerformanceEMC Compliance Recommendations 8. EMC Compliance Recommendations8.1 Recommendations for 2.4 GHz ETSI EN 300-328 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 20 dBm limit of the ETSI EN 300-328 in case of the conducted measurement but due to the high antenna gain the radiated power is higher than the limit by 2 dB. In order to comply, the output power should be reduced (with different antennas, depending on the gain of the used antenna, the necessary reduction can be different). The harmonic emissions are under the -30 dBm limit. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.8.2 Recommendations for 2.4 GHz FCC 15.247 complianceAs it was shown in the previous chapter, the radiated power of the fundamental of the BRD4161A Mighty Gecko Radio Board complies with the 30 dBm limit of the FCC 15.247. The harmonic emissions are under the -37.6 dBm applied limit both in case of the conducted and the radiated measurements. Although the BRD4161A Radio Board has an option for mounting a shielding can, that is not required for the compliance.Document Revision History 9. Document Revision HistoryTable 9.1.

竭诚为您提供优质文档/双击可除2.4g无线通信协议篇一：无线技术知识2.4g无线技术知识2.4g与其他无线技术对比●从理论上来讲，2.4ghz是工作在ism频段的一个频段。
ism频段是工业，科学和医用频段。
一般来说世界各国均保留了一些无线频段，以用于工业，科学研究，和微波医疗方面的应用。
应用这些频段无需许可证，只需要遵守一定的发射功率(一般低于1w)，并且不要对其它频段造成干扰即可。
●ism频段在各国的规定并不统一。
而2.4ghz为各国共同的ism频段。
因此无线局域网(ieee802.11b/ieee802.11g)，蓝牙，zigbee等无线网络，均可工作在2.4ghz频段上。
●大家所谓的2.4g无线技术，其频段处于2.405ghz-2.485ghz(科学、医药、农业)之间。
所以简称为2.4g无线技术。
●2.4g免费频段是什么意思免费频段，是指各个国家根据各自的实际情况，并考虑尽可能与世界其他国家规定的一致性，而划分出来的一个频段，专门用于工业，医疗以及科学研究使用(ism频段)，不需申请而可以免费使用的频段。
我们国家的2.4g频段，就是这样一个频段。
然而，为了保证大家都可以合理使用，国家对该频段内的无线收发设备，在不同环境下的使用功率做了相应的限制。
例如在城市环境下，发射功率不能超过100mw。
●2.4g无线键鼠收发模块挪威著名芯片厂商的nRF24l01无线收发芯片nRF24l01是单片射频收发芯片，工作于2.4～2.5ghzism 频段。
工作电压为1.9～3.6V，有多达125个频道可供选择。
可通过spi写入数据，最高可达10mb/s，数据传输率最快可达2mb/s，并且有自动应答和自动再发射功能。
和上一代nRF2401相比，nRF24l01数据传输率更快，数据写入速度更高，内嵌的功能更完备。
芯片能耗非常低，以-6dbm的功率发射时，工作电流只有9ma，接收时工作电流只有12.3ma，多种低功率工作模式(掉电模式和空闲模式)使节能设计更方便。
