1. CTS (Comprehensive Test Software): Involves more manual configuration and complex validation. Protocol analyzers can be used for analysis.

2. MTS (Manual Test Software): Simple manual validation, often used for easy testing on the production line.

3. ATS (Auto Test Software): Automated testing program with script editing capabilities. Used for testing on the production line and includes automation.

4. iATS: Allows simultaneous validation of multiple DUTs within automated programs. Includes script editing capabilities.

ALifecom no longer offers testing methods for GSM/WCDMA and 3G technologies. This is due to GSM already being released in Taiwan, and WCDMA is also on the verge of full release. Therefore, the focus of test and measurement instrument  will shift towards newer 3GPP technologies

Since the test and measurement instrument is designed for signaling testing, the connection process is carried out through protocols. Additionally, the test and measurement instrument  follows the 3GPP Protocol Stack specifications. Hence, it doesn't require chipset-level control and can proceed with testing.

2．EVM (Tx)

3．ACLR (Tx)

4．OBW (Tx)

5．RSSI/RSRP/RSRQ (Rx)

6．Sensitivity (Rx)

1．MAC Throughput

2．IP Throughput (Iperf, IxChariot…)

3．SAR power sweep

4．PWS (Public Warning System)

5．Attach test 

6．IPv4/v6 test

7．PDN/DNN test

8．UE Capability

9．Multi-DUT(Up to 4 User Equipment (UE) )

10．VoLTE/SMS(UEs can make calls to each other or send text messages.)

1．Conductive test (If the DUT PCBA retains antenna holes, it can be interfaced using Murata or Ipex cables)

2．OTA test (Typically, after assembly is complete, an external antenna is coupled using contact coupling)

1. The main antenna is always located at the rightmost port of the instrument and needs to be interfaced with the DUT's main antenna.

2. For the other AUX antennas, they can be connected to any port except the rightmost one.

1. Testing generally cannot be performed using physical SIM cards due to security mechanisms imposed by telecom providers. The SIM card's key number is protected and not provided, which is why testing SIM cards need to be used for testing the DUT.

2. The AKA keys for the testing SIM cards come in two variants: 000102030405060708090A0B0C0D0E0F and 00112233445566778899AABBCCDDEEFF.

3. NE7500/NE6000 can work with eSIM methodology, bypassing certain security authentication. However, the DUT also needs to bypass security authentication for testing to proceed.

Connecting to the external network involves the following steps:

First, establish a connection for the DUT, then configure the external network's DNS and Gateway. This will allow you to ping external network IP addresses.

When the DUT enters an area with poor signal reception, and the base station cannot locate the UE (User Equipment) within its designated area, the DUT's record is temporarily stored in the MME (Mobility Management Entity). This action triggers the DUT to enter Idle mode. During this period, the instrument simulates the base station by periodically inquiring if the UE is still present. It will make three inquiry attempts before initiating a Detach process for the DUT

When installing CTS with the ALifecom GUI, Wireshark will be installed simultaneously. You can then open Wireshark through the CTS GUI by selecting the Protocol Analyzer option.

Once connected to the DUT using CTS/MTS GUI and confirmed the obtained system-side IP Address (e.g., 192.168.11.2) with successful pinging, proceed to ping back to the controlling computer's IP Address from the DUT. Successful ping back indicates connectivity. You can then use Iperf for further validation.
