Being aware of the responsibilities
All licensed devices that operate using standard regulation under (for example) 3GPP or ETSI have to conform to certain pre-defined test cases. These test cases are specific to different standards such as GSM or LTE etc & are divided into transmitter, receiver and protocol sub-categories.
Transmitter Test Cases
These may include the following:
- Maximum Output Power
- Frequency Error
- Spectrum Emission Mask
- Spurious Transmitter Emissions
- Transmit Intermodulation
Fenztraq GmbH can provide advice and design verification for you.
Receiver Test Cases
These may include the following;
Reference Sensitivity Level
Maximum Input Level
Protocol Test Cases
These may include the following
- Single Antenna Port Performance
- Transmit Diversity
- Spatial Multiplexing
- Reporting under AWGN Conditions
- Reporting under Fading Conditions
A conformance test system is able to automatically run through all of these test cases to see if a new product can be licensed and approved for the market.
