## Features

* Easy to use web and mobile interface

* Simulate: bandwidth, delay, loss, corruption, occasional loss of signal

* Can capture the traffic and send it to CloudShark

* Apply limits per-device

* Works well in environment with multiple devices and multiple testers

* Works well as virtual machine bridged with separate wireless network

## Requirements

* OpenWrt device running on [**Barrier Breaker**](http://downloads.openwrt.org/barrier_breaker/14.07/) - can be router or virtual machine

* Two network interfaces - one for WAN and one for WIFI/LAN

## Installation

The are a few simple steps to install Cellular Data Network Simulator:

1. Install cdns:

        opkg update

        opkg install http://polidea.github.io/Cellular-Data-Network-Simulator/cdns_0.5-3_all.ipk

        

    Installation of Cellular Data Network Simulator replaces default Luci webpage. The Luci can be accessed using: http://ip-address/index-old.html

2. Configure:

        vim /etc/config/cdns

    By default there are 5 profiles: Full, HSDPA, Edge, GPRS and Disabled.

    

    In order to support packet capture uploads to Cloudshark, you must edit the cloudshark_api_token parameter. You must create an account at https://www.cloudshark.org and retrieve your API token from the Preferences / API Tokens drop-down menu.

3. Start the service:

        /etc/init.d/cdns enable

        /etc/init.d/cdns start

        

    That simply enables and starts the service,

        

4. Start the uhttpd daemon:

        /etc/init.d/uhttpd enable

        /etc/init.d/uhttpd start

    If you didn’t do it before you have to enable and start the uhttpd daemon.

    

5. Start using:

    Simply open: http://ip-address/.

## Uninstallation

        /etc/init.d/cdns stop

        opkg remove cdns

## Compile yourself

1. Download sources:

        git clone 

        

2. Build the package yourself:
