`Radio Specification
`1 SCOPE
`
`The Bluetooth transceiver is operating in the 2.4 GHz ISM band. This specifica-
`tion defines the requirements for a Bluetooth transceiver operating in this unli-
`censed band.
`
`Requirements are defined for two reasons:
`• Provide compatibility between the radios used in the system
`• Define the quality of the system
`
`The Bluetooth transceiver shall fulfil the stated requirements under the operating
`conditions specified in Appendix A and Appendix B. The Radio parameters must
`be measured according to the methods described in the RF Test Specification.
`This specification is based on the established regulations for Europe, Japan and North Amer-
`ica. The standard documents listed below are only for information, and are subject to change
`or revision at any time.
`Europe (except France and Spain):
`Approval Standards: European Telecommunications Standards Institute, ETSI
`Documents: ETS 300-328, ETS 300-826

`Approval Authority: Direction Generale des Postes et Telecommunications
`Note: A new R&TTE EU Directive will be in effect by March 2000, with consequent effects on
`the manufacturer’s declaration of conformity and free circulation of products within the EU.

`2 FREQUENCY BANDS AND CHANNEL
`ARRANGEMENT
`
`The Bluetooth system is operating in the 2.4 GHz ISM (Industrial Scientific
`Medicine) band. In a vast majority of countries around the world the range of
`this frequency band is 2400 - 2483.5 MHz. Some countries have however
`national limitations in the frequency range. In order to comply with these
`national limitations, special frequency hopping algorithms have been specified
`for these countries. It should be noted that products implementing the reduced
`frequency band will not work with products implementing the full band. The
`products implementing the reduced frequency band must therefore be consid-
`ered as local versions for a single market. The Bluetooth SIG has launched a
`campaign to overcome these difficulties and reach total harmonization of the
`frequency band.

`Table 2.1: Operating frequency bands
`Note 1. Japan, the MPT announced at the beginning of October 1999 that the Japanese
`frequency band would be extended to 2400-2483.5 MHz, effective immediately.
`Testing of devices by TELEC may however need some time to change. The previ-
`ously specified special frequency-hopping algorithm covering 2471-2497 MHz
`remains as an option.
`Note 2. There is a proposal in Spain to extend the national frequency band to 2403-
`2483.5 MHz. The Bluetooth SIG has approached the authorities in Spain to get a
`full harmonization. The outcome is expected by the beginning of year 2000.
`Note 3. The Bluetooth SIG has established good contacts with the French authorities and
`are closely following the development of harmonization.
`
`Channel spacing is 1 MHz. In order to comply with out-of-band regulations in
`each country, a guard band is used at the lower and upper band edge.

`The requirements stated in this section are given as power levels at the
`antenna connector of the equipment. If the equipment does not have a connec-
`tor, a reference antenna with 0 dBi gain is assumed.
`
`Due to difficulty in measurement accuracy in radiated measurements, it is pre-
`ferred that systems with an integral antenna provide a temporary antenna con-
`nector during type approval.
`
`If transmitting antennas of directional gain greater than 0 dBi are used, the
`applicable paragraphs in ETSI 300 328 and FCC part 15 must be compensated
`for.
`
`The equipment is classified into three power classes.

`Note 1. Minimum output power at maximum power setting.
`Note 2. The lower power limit Pmin<-30dBm is suggested but is not mandatory, and may
`be chosen according to application needs.
`
`A power control is required for power class 1 equipment. The power control is
`used for limiting the transmitted power over 0 dBm. Power control capability
`under 0 dBm is optional and could be used for optimizing the power consump-
`tion and overall interference level. The power steps shall form a monotonic
`sequence, with a maximum step size of 8 dB and a minimum step size of 2 dB.
`A class 1 equipment with a maximum transmit power of +20 must be able to
`control its transmit power down to 4 dBm or less.
`
`Equipment with power control capability optimizes the output power in a link
`with LMP commands (see Link Manager Protocol). It is done by measuring
`RSSI and report back if the power should be increased or decreased.

`3.1 MODULATION CHARACTERISTICS
`The Modulation is GFSK (Gaussian Frequency Shift Keying) with a BT=0.5.
`The Modulation index must be between 0.28 and 0.35. A binary one is repre-
`sented by a positive frequency deviation, and a binary zero is represented by a
`negative frequency deviation. The symbol timing shall be better than ±20 ppm.

`
`For each transmit channel, the minimum frequency deviation (Fmin = the
`lesser of {Fmin+, Fmin-}) which corresponds to 1010 sequence shall be no
`smaller than ±80% of the frequency deviation (fd) which corresponds to a
`00001111 sequence.
`In addition, the minimum deviation shall never be smaller than 115 kHz.
`
`The zero crossing error is the time difference between the ideal symbol period
`and the measured crossing time. This shall be less than ± 1/8 of a symbol
`period.
`
`3.2 SPURIOUS EMISSIONS
`
`The spurious emission, in-band and out-of-band, is measured with a frequency
`hopping transmitter hopping on a single frequency; this means that the synthe-
`sizer must change frequency between receive slot and transmit slot, but
`always returns to the same transmit frequency.
`
`For the USA, FCC parts 15.247, 15.249, 15.205 and 15.209 are applicable reg-
`ulations. For Japan, RCR STD-33 applies and, for Europe, ETSI 300 328.

`
`3.2.1 In-band Spurious Emission
`
`Within the ISM band the transmitter shall pass a spectrum mask, given in
`Table 3.2. The spectrum must comply with the FCC’s 20-dB bandwidth defini-
`tion stated below, and should be measured accordingly. In addition to the FCC
`requirement an adjacent channel power on adjacent channels with a difference
`in channel number of two or greater an adjacent channel power is defined. This
`adjacent channel power is defined as the sum of the measured power in a
`1 MHz channel. The transmitted power shall be measured in a 100 kHz band-
`width using maximum hold. The transmitter is transmitting on channel M and
`the adjacent channel power is measured on channel number N. The transmit-
`ter is sending a pseudo random data pattern throughout the test.

`Note: If the output power is less than 0dBm then, wherever appropriate, the FCC’s 20 dB
`relative requirement overrules the absolute adjacent channel power requirement
`stated in the above table.
`
`-40 dBm
`
`“In any 100 kHz bandwidth outside the frequency band in which the spread spectrum intentional radiator
`is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB
`below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power,
`based on either an RF conducted or a radiated measurement. Attenuation below the general limits speci-
`fied in § 15.209(a) is not required. In addition, radiated emissions which fall in the restricted bands, as
`defined in § 15.205(a), must also comply with the radiated emission limits specified in § 15.209(a) (see §
`15.205(c)).”
`
`FCC Part 15.247c
`
`Exceptions are allowed in up to three bands of 1 MHz width centered on a fre-
`quency which is an integer multiple of 1 MHz. They must, however, comply with
`an absolute value of –20 dBm.
`
`3.2.2 Out-of-Band Spurious Emission
`
`The measured power should be measured in a 100 kHz bandwidth.
