MINT E1130 - WiMAX Signalling Unit
MINT E1130 emulates either a 802.16-2005 BS or MS and records the messages transferred between the unit and the device under test.
MAC and upper layers protocol can be defined by the user, so invalid behaviours can be easily emulated or portions of the stack can be bypassed, allowing testing of partial implementations.
Key Features
- Software defined radio architecture, allowing easy change between BS and MS roles and future evolutions with the standard
- Embedded fading emulation, supporting predefined (SUI, 3GPP FDD) and customizable channel models
- Capable of supporting 2x2 MIMO by means of two transceivers and antenna connectors, without the need of additional hardware
- Upper layers simulated via TTCN-3 scripts
- MAC and PHY logging capabilities
- Supports TDD, H-FDD and FDD profiles up to 10 MHz channel bandwidth
- Frequency coverage: 2300 - 2700 MHz, 3300 - 3900 MHz
- Easy configuration and programming of the signaling unit using an API
- Scalable architecture that allows a coordinated operation of several signaling units, controlled using a single API
MINT T2100 - Pre-RCT for WiMAX
|
MINT T2100 is a test system developed by AT4 wireless for Mobile WiMAX™ testing for both WiMAX Mobile Stations and Base Stations.
Based on the MINT E1130 hardware, the MINT T2100 Pre-RCT for WiMAX provides a set of RF and physical layer tests and allows validation of the design prior to conformance testing, thus reducing the certification testing costs. By adding stand-alone test equipment, the MINT T2100 Pre-RCT for WiMAX can provide wider test coverage and higher dynamic range measurement and can be upgraded to a full conformance RCT.
The MINT E1130 also provides BER measurement and signalling capabilities necessary to perform Radiated PerformanceTesting according to the test specifications defined by the WiMAX Forum.
MINT T2100 supports the following profiles:
- Profile 1A: 2.3 GHz, 8,75 MHz
- Profile 3A: 2.5 GHz, 5MHz, 10MHz
- Profile 5BL: 3.5 GHz, 7MHz
The platform will be capable to support profiles in other frequency bands and bandwidths.
Key Features
AT4 wireless current experience in hardware and software development and the active participation of AT4 wireless in the WiMAX Forum Working Groups ensure that MINT T2100 is the right testing solution for the WiMAX industry because:
- Provides the straight path to WiMAX certification
- Helps from the development to the certification stage of your WiMAX product
- Provides highly reliable and repeatable measurements
- Can be upgraded to other radio access technologies
- The powerful and user-friendly Test Manager software eases your testing processes
- AT4 wireless long experience in the development of RF test Solutions for other wireless Technologies (Bluetooth®, GSM, WCDMA)

MINT T2110 - Radio Conformance Tester
MINT T2110 is the radio conformance test platform developed by AT4 wireless and designated by the WiMAX Forum for certification of 802.16-2004 and 802.16-2005 devices. This platform covers the official test cases for certification of Base Stations (BS) and Subscriber Stations (SS) according to the WiMAX Forum profiles.
It covers transmitter test cases such as modulation and coding, spectral flatness and constellation error and receiver test cases in which the sensitivity of the Unit Under Test (UUT) is tested by using non-ideal WiMAX and/or interfering signals. MINT T2110 is an open testing platform that can be upgraded to support existing and future radio access technologies, test cases and frequency bands.
Key Features
- Agilent state of the art, top of their class instruments
- OFDM, OFDMA support
- Based on AT4 wireless WSU for WiMAX (future proof)
- Simulation of various cells, RRM support
- Software radio (emulation of BS or MS by software)
