1. Introduction
This document covers the functional description and specification of this project.
2. Product Overview
The Belkin F7D4402 Play Wireless is a modem-router/access point (AP), which
operates on 2.4GHz and 5GHz frequencies, conforms to the IEEE 802.11a/b/g/n
wireless standards. It allows sharing of broadband connections up to 16 computers via
the WLAN and 4 computers via the 4-port Fast Ethernet (10/100Base-T) switch.
The Router’s new Easy Start installation software operates on Microsoft’s Windows XP,
Vista, Win7 and on Mac OS X. The Router can be configured through a web-browser
interface. The product is designed for the home and small office and will be available
through major retailers and online retailers.

2.2 System Requirements
Broadband Internet connection, RJ11 ADSL
At least one PC with:
o Installed network card
o TCP/IP networking protocol installed
o Internet Browser installed (IE Safari, Opera, Firefox)
2.3 New Belkin Easy Start Wizard and Tray App System Requirements:
At least one PC with:
o Installed network card
o TCP/IP networking protocol installed
o Windows XP SP2 or later, Vista, Win7 or Mac 10.4 and 10.5
o CD-ROM drive
o Minimum of 256MB RAM
2.4 Key Project Priorities
2.4.1 QoS for Best User Experience
The QoS feature will automatically allocate bandwidth to applications that are latency
sensitive, video, voice, gaming. This will ensure that users have a seamless online
experience. Advanced users will also have the ability to manually change the settings to
suit their specific needs.
2.4.2 USB Port for Storage, Printing and Back-up
One of the key differentiators of this router is the USB port that allows users to access a
connected storage device (FAT, FAT32, NTFS) on their home network.
Mac 10.4, 10.5 and 10.6 users will be able to see the USB device appear automatically in
the network section.
Vista/Win7 users will also be able to see the device automatically from the network
section.
See latest version of the ‘Local Backup’.pdf document for the specifications
2.4.3 DLNA/UPnP AV Server for Streaming Media
Belkin International Confidential

Product Requirements Document F7D4402 v1000
Play Wireless Modem-Router
The UPnP server will automatically broadcast its media serving capabilities to the rest of
the network, devices such as PS3, Xbox, Windows Media player, etc will pick up this
broadcast and allow users to access the UPnP server.
The server will serve photos, videos, and music that are on the USB storage device
connected to the router’s USB port.
Must be DLNA certified
2.5 USB Storage installation procedure and usage
• See Affinegy tray app and Silex specification document
2.6 Requirements for USB Use Cases
All users on the local network (wired and wireless) should see the attached USB storage device as a folder in their
“My Computer” folder once the device is plugged into the USB port and the Silex control center software is
installed. All users will have read and write access to all files on the storage device. The following are special cases
that the firmware must handle:
2.6.1 All users will be able to navigate to the storage device through \\192.168.2.1\
2.6.2 If the device plugged into the USB port is not a storage device or if file system of the
storage device is unsupported (FAT, FAT32, or NTFS), the USB LED will stay off
• Card readers will be accessible if they are formatted to a supported file system
2.6.3 Router will support up to a 4 to 1 externally-powered USB hub
• At least one device must be a supported storage device. All others will be ignored
2.6.4 File attributes (such as permissions) are maintained when accessed through the router’s
USB port
2.6.5 User experience must be OS-independent: XP, Vista, Win7 and MAC
2.6.6 Under no circumstances will the user’s storage device be formatted
2.6.7 If the user installs the Silex control center utility from the CD, the storage device will
be mapped to a drive letter on the user’s My Computer folder in their PC or the Finder in
their MAC
• The drive letter order will be in reverse alphabetical order to match the networked
drive handling in Windows OS
• Multiple partitions/multiple drives via USB hub will be mounted to separate drive
letters
• The volume name of the storage device must be displayed
• The icon should be customized
o The icon to change when a drive is plugged into the router

• If a new drive is plugged into the port, the same drive letter can be reused but with a
new volume name
• Multiple users must have simultaneous access to the storage device
2.6.8 Silex control center functionality
• See separate Silex specification
