EmulationEngine 11a/b/g User's Guide

080104 1-1

CHAPTER 1: Overview

The EmulationEngine is a test and measurement device that emulates up

to 64 wireless stations in an IEEE 802.11 wireless LAN environment. The

EmulationEngine operates in accordance with the IEEE 802.11a, 802.11b,

and 802.11g specifications. The EmulationEngine is offered in three

configurations:

!" EmulationEngine 11a: Supports IEEE 802.11a only.

!" EmulationEngine 11b: Supports IEEE 802.11b only.

!" EmulationEngine 11a/b/g: Supports IEEE 802.11a, 802.11b, and 802.11g.

Each configuration is shipped with a unique feature key that is stored in

the EmulationEngine’s flash file system. The EmulationEngine software is

locked to its specific hardware platform and feature set through the use of

this feature key. Feature keys can be upgraded at any time to provide

access to additional features.

The objective of the EmulationEngine is to reduce the number of PC and

station NIC cards that are needed to test and stage 802.11 products and

wireless LANs in terms of packet performance and number-of-stations

capacity. In addition, it allows a user to fine-tune system parameters in

order to maximize performance during testing. The primary difference

between the EmulationEngine and other IP Load Generators is:

!" IP-based Load Generators are per-station devices that do not reduce the

number of PCs and station NIC cards. You can only configure an IP per

station and then send traffic.

!" The EmulationEngine allows all stations to be emulated on a single

platform and radio chipset thus reducing the cost and complexity of

multiple PCs.

CMC's EmulationEngine creates Virtual Stations (vSTAs) and generates or

passes traffic that will load and stress test a Wireless LAN and 802.11

products in terms of:

!" Frame performance

!" Number-of-stations capacity

!" Scalability

!" WLAN optimization

Because a single physical 802.11a/b/g emulator emulates multiple STAs,

it reduces the number of PC and station NIC cards that are needed to test

and stage 802.11 products and wireless LANs.

Files

The following files are maintained in the EmulationEngine’s flash file

system:

1) EmulationEngine Configuration (eecfg)

2) Scenario definitions

3) Logs

4) Statistics

5) EE22.SYS

6) keyfile

1) The EmulationEngine configuration file (eecfg) stores information

settings that can be defined via the CLI or the web-based user interface. A

backup version (.bak) of this file is also maintained in the unlikely event

that the original might become corrupted. The EmulationEngine will load

from this file at power-up/initialization time. It contains basic

configuration information.

2) After the EmulationEngine is configured, you may create test scenarios

that contain virtual station definitions that are organized into groups. This

information is stored in scenario files. The scenario files are created and

used by the web-based user interface. The CLI does not create or use

scenario files.

3) Log files store records of all EmulationEngine activities with a time

stamp indicating when the activity occurred. Logging to the CLI console,

the web-based user interface, or a file can be enabled/disabled.

4) Statistics files contain statistics of a test (scenario) run. When a test is

complete, a statistics file can be written in the flash file system for each

virtual station involved in the test. The Reports section of the web-based

user interface can be used to show the contents of these files.

5) The EE22.SYS file is the EmulationEngine software image file.

6) The keyfile is a reserved file that contains the EmulationEngine

authorization code. It is a hidden file and will only be shown in the

directory list in the CLI’s administrative mode. Do not delete this file or

attempt to access or modify it. It is required by the system.

System Requirements

!" An A/C power outlet (100~240 V, 50~60 Hz) that will supply power to the

EmulationEngine

!" A PC with an available serial port or 10/100 Ethernet port that can be

Hardware Characteristics

Ethernet Compatibility: The EmulationEngine can attach directly to

10BASE-T/100BASE-TX (twisted-pair) Ethernet LAN Hubs, segments or a

PC. All of these must conform to the IEEE 802.3 specification.

Radio Characteristics: The EmulationEngine conforms to the IEEE

802.11a, 802.11b, and 802.11g specifications. In 802.11a mode, it

operates at the 5GHz Unlicensed National Information Infrastructure

(UNII) band. Data is transmitted over a half-duplex radio channel

operating at up to 54 Megabits per second (Mbps) using OFDM

(Orthogonal Frequency Division Multiplexing). In 802.11b mode, the

EmulationEngine operates in the 2.4 GHz band and sends data at up to 11

Mbps. In 802.11g mode, the EmulationEngine operates within the 2.4 GHz

band using OFDM at rates up to 54 Mbps.

General Usage Notes

1) The EmulationEngine's default IP address is 192.168.0.50. In order to

establish initial communications between the command PC and the

EmulationEngine using an Ethernet connection, you must set your PC's IP

address and network mask to match this default address (e.g., IP

address: 192.168.0.2, Netmask: 255.255.255.0). After you establish

communications using the default IP address, you can change the

EmulationEngine's and your command PC's address to match the

addressing scheme used in your network.

2) Depending on your feature key, the EmulationEngine can operate in

802.11a, 802.11b, or 802.11g wireless mode. The EmulationEngine's

wireless mode affects the devices that you can select as a System Under

Test. For example, an EmulationEngine that is operating in 802.11a

wireless mode will not discover an 802.11b or 802.11g device. Make sure

the wireless mode you select for the EmulationEngine is compatible with

the device you wish to test. See EE->Configure EE in Chapter 5 and “set

wirelessmode” in Chapter 6.

3) The EmulationEngine's Wireless LAN MAC address defaults to a specific

address (typically in the 00:0b:cd:xx:xx:xx range). It is a globally unique

MAC address that is programmed in to the EmulationEngine hardware.

The WLAN base MAC address and mask (ff:ff:ff:ff:00:00) define the range

of MAC addresses that can be assigned to virtual stations. When you

specify a starting MAC address for virtual stations, make sure that address

is within the range defined by the WLAN base MAC address and mask. See

vSTA->New Emulation Group->vSTA and EE->Configure EE in Chapter 5

and “set eemac” and “set eemask” in Chapter 6.

4) The default WLAN base MAC address can be overridden to prevent

conflict with other wireless devices. If you use multiple EmulationEngines

at your facility, each should have a WLAN MAC whose prefix is unique. For

example, on the first EmulationEngine, use WLAN MAC Address:

04:0d:e0:62:23:57 and on the second EmulationEngine, use WLAN MAC

Address: 06:0f:14:62:32:a0.

5) The IP Mask of the EmulationEngine must match the IP subnet

addressing scheme for internal mode testing (it is not used for external

mode). For example, if the EmulationEngine's IP address is 10.1.40.18

and the System Under Test is 10.1.35.17, then the subnet mask must be

16 bits or 255.255.0.0 for an internal mode test.

NOTE: The Ethernet LED is normally ON while a link is detected. It turns

OFF when a packet is received or transmitted. The OFF period is 50

milliseconds. If packets are being transmitted or received every 50

milliseconds or faster (e.g., 20 packets per seconds evenly spaced) for a

sustained period, the LED will stay off. This is done by the hardware and

the timing/proportionality is not adjustable.
