5、Test items and conformance standards
5.1 Test items and conformance standards of wireless interface:
5.1.1 Operation within the bands 2400-2483.5 MHz
5.1.2 The maximum output power:
For frequency hopping systems in the 2400-2483.5 MHz band employing at least 75 hopping channels and all digitally modulated system: 1 watt. For all other frequency hopping systems in the 2400-2483.5 MHz band: 0.125 watts.
5.1.3 Bandwidth, channel number and other limitations:
126.96.36.199 Frequency hopping system:
188.8.131.52.1 Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. If at least 75 hopping frequencies are used. The maximum 20 dB bandwidth of the hopping channel is 1 MHz. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals.
184.108.40.206.2 Frequency hopping systems in the 2400-2483.5 MHz band shall use at least 15 non-overlapping channels. The average time of occupancy on any channel shall not be greater than 0.4. Frequency hopping systems which use fewer than 75 hopping frequencies may employ intelligent hopping techniques to avoid interference to other transmissions.
220.127.116.11.3 Frequency hopping spread spectrum systems are not required to employ all available hopping channels during each transmission. However, the system, consisting of both the transmitter and the receiver, must be designed to comply with all of the regulations in this section should the transmitter be presented with a continuous data (or information) stream. In addition, a system employing short transmission bursts must comply with the definition of a frequency hopping system and must distribute its transmissions over the minimum number of hopping channels specified in the 18.104.22.168.2.
22.214.171.124.4 The incorporation of intelligence within a frequency hopping spread spectrum system that permits the system to recognize other users within the spectrum band so that it individually and independently chooses and adapts its hopsets to avoid hopping on occupied channels is permitted. The coordination of frequency hopping systems in any other manner for the express purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters is not permitted.
126.96.36.199 Digital modulation techniques:
188.8.131.52.1 For Digitally modulated system, the minimum 6 dB bandwidth shall be at least 500 kHz.
184.108.40.206.2 If Digitally modulated techniques system is utilized, at least 11 channels for end user to select individual and independent channel shall be furnished.
220.127.116.11.3 For digitally modulated systems, the peak power spectral density conducted from the intentional radiator to the antenna shall not be greater than 8 dBm in any 3 kHz band during any time interval of continuous transmission.
18.104.22.168 The hybrid system:
The hybrid systems employ a combination of both frequency hopping and digital modulation techniques.
22.214.171.124.1 The frequency hopping operation of the hybrid system, with the digitally modulated operation turned off, shall have an average time of occupancy on any frequency not to exceed 0.4 seconds within a time period in seconds equal to the number of hopping frequencies employed multiplied by 0.4.
126.96.36.199.2 The digital modulation operation of the hybrid system, with the frequency hopping turned off, shall comply with the power density requirements of those specified in 188.8.131.52.3.
5.1.4 RF Conducted emission outside the frequency band:
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated 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. In addition, radiated emissions which fall in the restricted bands, as defined in "Low-power radio-frequency devices technical specifications"(LP0002) Section 2.7 must also comply with the radiated emission limits specified in Table I.
5.1.5 Radiated emission outside the frequency band:
Except as specified in the Section 5.14. The emissions outside the frequency band from an intentional radiator shall not exceed the field strength levels specified in the following table:
5.1.6 Antenna requirement:
Radio frequency TTE transmitter or receiver shall utilize a permanently, half- permanently attached antenna or uses a unique coupling at the antenna and at any cable connector between the transmitter and the antenna. The antenna shall be omnidirectional type. The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a standard antenna jack or electrical connector or other than authorized is prohibited. Such a standard connectors are for example: BNC, F type, N type, M type, UG type, RCA, SMA, SMB, and other standard type antenna connectors.
5.1.7 Security code:
It is permissible to provide at least 1000 possible different combinations for both base and handset unit to automatically select security code. (a Declaration of Conformance should be provided by the manufacturer)
5.1.8 Check list for wireless interface is as Table II below:
5.2 PSTN interface and conformance standards is listed as Table III。 Wireline interface test items shall follow PSTN01[Technical Specifications for Terminal Equipment for Connection to Public Switched Telephone Network].
5.3 In terms of Telecommunications terminal equipment with PLMN interface, the test items and conformance standards shall refer to technical specification from PLMN01 to PLMN08.
