LTS-Platform | Main Characteristics

LTS Systems - Realizations


Rack setups with commercial mobiles / datasticks,

controlled via USB interface

Combination of various

mobile types and vendors

Compact, portable setups,

based on module solutions

(GSM, UMTS, HSPA)

(6 modules per 19`` drawer)

powerful analysis

capabilities for

end-to-end failures

RF Shielding


Each datastick is located in its own shielded box

- High shielding performance for all mobile networks

> 40 dB shielding guaranteed for 3G and 4G frequency bands

- MIMO capable (2 antenna connectors)

- Size: 16 cm x 11 cm x 6 cm (L x B x H)

optimized to mount 8 boxes on a 19‘‘ shelf

Creating Test Scripts


Easily assemble test steps to test cases by simple

drag & drop actions

1,2 or more mobiles can be involved in a test case

Standard test scripts predefined by Qosmotec

Drag &

drop

Building automatic test sessions


Test execution methods


LTS supports

repeated execution of test cases within a test scenario

parallel and sequential execution of test case within a test scenario

scheduled or immediate test scenario execution

automatic repetitions of a test scenario in user defined periods, e.g.

- hourly

- daily

- weekly

- monthly

Test Features – PS Data


PS Data Transmission between Mobile Control Server and Test Host via a

selected datastick to test the performance of the mobile network

- Various protocols (ICMP, FTP, HTTP)

- LTE data speeds up to 100 Mbps (DL) / 50 Mbps (UL)

- Bandwidth selectable for uplink and downlink speed

- Measurements of user data throughput and network data throughput

- TCP dump for detailled traffic flow analysis with Wireshark integrated

Analyzing the TCP Dump

For each IP Session,

the tcpdump is

saved

Call TCP analysis software

for detailed data session
