What is TM500 ?

TM500 is a family of software defined products• Based on a common highly configurable hardware platform, for testing LTE

eNodeBs.

Industry Standard• Used by every major macro & small cell vendor

• 17 years of experience for Test Mobile product Line

• Independent test mobile for IOT assurance

• Multiple Technologies (WCDMA and LTE)

• Powerful platform with the latest DSP & FPGA processors

• Software defined radio architecture (multiple bands)

Strong Technology Roadmap • 3GPP & customer driven roadmaps

• Supports latest 3GPP Release 11/12/13 functionality

Support• World Class global industry technical support


TM500 Family

Two lines of LTE products • Frequency Division Duplex (FDD)

• Time Division Duplex (TDD)

Within each line there are 3 primary products

SUE OTA:

• Simulates one highly controllable UE

Extended MUE (EMUE):

• Simulates up to 1500 UEs for testing of base station capacity

E500:

• A composite system capable of simulating up to 24000 UEs (depending on hardware configuration)


TM500 Family

Products are available to simulate from one to thousands of UEs (mobile devices)


TM500 Family

Things the products have in common

• All support full protocol stack up to layer 3 (RRC and NAS)

• All come with support for Semi-Persistent Scheduling (SPS) and TTI-bundling standard*

• All can support Robust Header Compression (RoHC) as a chargeable option*

• All support multiple PDNs (either IPv4 or IPv6) as standard

• All support multiple dedicated bearers as standard

• All support independent configuration of each UE, including: CAT 1,2,3,4 Operation standard

Radio Modules

Narrow band radio modules• Performance similar to commercial (aka real) UEs

• Each module only supports two specific bands

• Suitable for OTA testing (e.g. drive testing)

Multi-band radio modules (MBR) • Can support any radio frequency 400MHz – 4GHz

• New LTE-U radio card 400MHz - 6GHz

• New Compact Radio Card (C-MBR)

• Consequently can support any LTE band currently specified or to be specified in the future.

* Only suitable for testing in a lab environment with direct cabled connections to the

eNodeB under test

Currently TM500 can support 2 or 3 radio cards per chassis.

OTA Single UE (SUE)

Supports Over the Air operation to eNodeB

• All other products require a direct connection (RF Cable) to a single eNodeB

• Supports HO between cells in one TM500

• Supports all transmission modes

• Support eMBMS

• Is most suitable for development of the physical layer including link adaptation

• Is very suitable for feature development

• Is suitable for drive testing


Extended Multi-UE (EMUE)

13


Extended Multi-UE (EMUE)

Supports simulation of up to 1500 UE per carrier

Used in Lab environment in conducted mode (RF Cable)

Supports integrated control of the Real Data Applications option

Is most suitable for testing eNodeB capacity testing

Is very suitable for testing MME * control plane capacity

In conjunction with D500/D1000 RDA option is very suitable for testing “end to end” user plane throughput, latency, and capacity

*MME: Mobility Management Entity


E500 Platform

Composite system made up of an access concentrator and up to 12 cell units

All units are sub-rack variants of the TM500 chassis

Simulates up to 1500 UEs per chassis, up to 24000 UEs per system

Supports full mobility testing from any cell to any cell

Supports configuration of UE profiles for application to groups of UEs

Is most suitable for testing MME* control plane capacity and EPC user plane capacity

*MME: Mobility Management Entity


Hardware

TM500 is controlled from an external PC, running the TMA application

1GHz Ethernet switch (supplied)

TM500 binary files are loaded on every power up, via FTP server (FileZilla supplied)

RF connection to eNodeB is via cable or Over The Air*

Easy to configure with one single point of control for both client and server• Integrated with TM500.

• Apps start/stop above bearer creation / deletion

Measurements allow cross layer correlation

Fast integration of new applications that appear in the market• D500 Support of 6 TM500 (6 different testers) maximize return on investment.

Realism in the lab• Simulations of thousands of UEs distributed across cells with mobility and real data applications replicates real

world in the lab.

• Mobility & Channel models is a TM500 option

DiversifEye500 “Per flow” architecture• Enables performance measurements for every emulated client or end point on per application basis

Thresholding capability• For quick exposure of issues in a large system

• Makes it possible to identify issues in a large load system
