- GSM cellular phones
a) Functional Tests for GSM technology
These tests include the so-called "voice GSM" technology and the associated data technologies, GPRS and EDGE. Each of these technologies must be tested separately. All test items refer to the numbers found in the ETSI Standard 3GPP TS 51.010-1, V6.5.0 (2005-11). The tests must done in all frequency bands in which the product can operate. In Brazil, cellular phones are permitted to operate in one or more of the frequency bands of 850, 900, 1800 and 1900 MHz. All tests are done without variations in ambient temperature and/or ac mains voltage.
a1) Tests for "voice GSM" technology
-12.1.1 - Emission of conducted undesired frequencies, with product in normal operation mode;
-12.1.2 - Emission of conducted undesired frequencies, product in idle mode.
- 12.2 - Emission of radiated undesirede frequencies;
- 13.1 - Phase and frequency errors;
- 13.3 - Transmitted output power, power control and burst duration.
a2) Tests for GPRS technology
-12.1.1 - Emission of conducted undesired frequencies, with product in normal operation mode;
-12.1.2 - Emission of conducted undesired frequencies, product in idle mode.
- 12.2 - Emission of radiated undesirede frequencies;
- 13.16.1 - Phase and frequency errors in the GPRS multiframe configuration;
- 13.16.2 - Transmitted output power in the GPRS multiframe configuration.
a3) Tests for EDGE technology
-12.1.1 - Emission of conducted undesired frequencies, with product in normal operation mode;
-12.1.2 - Emission of conducted undesired frequencies, product in idle mode.
- 12.2 - Emission of radiated undesirede frequencies;
- 13.17.1 - Phase and frequency errors in the EDGE configuration;
- 13.17.3 - Transmitted output power in the EDGE configuration.
Obs.: The tests numbered 12.1.1 and 12.1.2 may be done for the "voice GSM" technology and are considered as valid for the other technologies.
b) Specific Absortion Rate (SAR) tests.
These tests must be done on all cellular phones commercialized in Brazil, and must be done accordingly Anatel's Resolution Nº 303. The tests must be made in all frequency bands in which the cellular phone can operate.
- Bluetooth products
Tests for Bluetooth products must follow Anatel's Resolution Nº 365, Art. 40º and 44º. These articles specify the following tests:
- Frequency hopping carier frequencies separation;
- Maximum occupation time of any hopping channel;
- Maximum peak output power.
- RF output power produced out of desired band of operation.
- Wi-Fi 802.11a, b and g products.
Products that operate with 802.11b and g tehnologies must use the 2.4 to 2.4835 GHz band. On the other hand, products with 802.11a technology must operate in one of frequency bands 5.15 to 5.35 GHz and 5.47 to 5.725 GHz. At this time, no other frequency bands are permitted for 802.11a products.
a) Tests for products with 802.11b and g technologies must comply with Anatel's Resolution Nº 365, Articles 41º and 44º. These articles specify the following tests:
- Minimum channel bandwidth measured at 6 dB;
- Maximum peak output power of transmitter;
- Maximum peak power spectral density;
- RF output power produced out of desired band of operation.
b) Tests for products with 802.11a technologies must comply with Anatel's Resolution Nº365, Articles 45º to 50º. These articles specify the following tests:
-b1)For systems in the 5.15 to 5.35 GHz band:
- These systems must be used inside buildings;
- Maximum e.i.r.p.average power;
- Maximum average e.i.r.p.power spectral density;
- RF output power produced out of desired band of operation;
- These systems must have TPC (Transmit Power Control);
- Systems in the 5.25 to 5.35 GHz must have DFS (Dynamic Frequency Selection) mechanism and there are some tests for such mechanism.
-b2)For systems in the 5.47 to 5.725 GHz band:
- Maximum e.i.r.p.average power;
- Maximum output transmitter power;
- Maximum average e.i.r.p.power spectral density;
- RF output power produced out of desired band of operation;
- These systems must have TPC (Transmit Power Control);
- These systems must have DFS (Dynamic Frequency Selection) mechanism and there are some tests for such mechanism.
All tests listed above are functional tests for the several types of products, that is, they are tests to verify operating characteristics of these products. There are, addionally, EMC and Safety tests, that are listed below.
- EMC tests, conducted according to Anatel's Resolution Nº 442
- Emissions, conducted and radiated.
- Immunity tests, that include immunity to:
- Fast electrical transients;
- Conducted RF pertubations;
- Radiated RF perturbations;
- Electrostatic discharges;
- Electrical surges in AC mains input;
- Interruptions and Dips in AC mains input.
- Resistibility tests, that include:
- Surges in the AC mains input. These tests are done with roduct in powered state.
- Safety tests, conducted accordingly to Anatel's Resolution Nº 238
- Safety against electrical shock, caused by normal voltage and by overvoltage in AC mains input;
-Safety against excessive heating.
Cellular phone with or without features such as Bluetooth and others, are classified as Category I - Cellular Phone.
Products that use 802.11 b and g technologies are classified as Category II - Spread Spectrum Transceivers. On the other hand, products that use 802.11a technologies shold are classified as Category II - Restricted Radiation Equipment.
- Wi-Fi 802.11n Equipment
Tests for products with 802.11n must cover Anatel's Resolution Nº 365.
