3. Product Requirements
3.1 Hardware Requirements
WLAN Requirements
Marvell’s 88W8787 is the IC of choice for the WLAN module with the following basic
features enabled:
Single band: 2.4GHz
802.11e (Quality of Service)
802.11i (Enhanced Security)
High Throughput 20MHz channel
High Throughput 40MHz channel
Mixed Format
Greenfield Format
Short Guard Interval
STA and AP concurrency
Bluetooth Requirements
Marvell’s 88W8787 as the IC of choice for the Bluetooth module with the following features
enabled:
Bluetooth 2.1 + EDR
Bluetooth 3.0 with Unicast Connectionless Data (UCD)
All Bluetooth-Host transactions will be done via the SDIO interface. In other
words, there will be no need to use the UART, I2C, I2S, or PCM interfaces.
The following profiles are anticipated for Bluetooth.
Human Interface Device (HID)
Headset Profile (HSP)
Hands-Free Profile (HFP)
Audio/Video Remote Control Profile (AVRCP)
Advanced Audio Distribution Profile (A2DP)
Host Interface Connector
The plan is to use a board-to-board connector with a 3.0mm stacking height from the
bottom of the PWB module to the top of the main PWB.
B2B Connector Vendor: Foxconn
Wireless module side: P/N: QT510206-1101R-7H, 20pin, 0.5mmpitch.
System side: P/N: QT500206-1101R-8H

3.2 Hardware Architecture
The module design based on the MARVELL 88W8787 single chip integrated WiFi and BT
MAC/Baseband/RF Which implements IEEE802.11b/g/n and BTv.30+HS
Figure 1 Functional Block Diagram
MARVELL 88W8787 is a highly integrated, low-cost, low-power IEEE802.11 b/g /n MAC
/Baseband / RF WLAN and Bluetooth Baseband/RF. The SIP Module apply to WLAN
/Bluetooth cellular handsets ,WLAN/Bluetooth headsets, portable audio/video devices and
accessories , gaming platforms, and WLAN/Bluetooth enabled digital still cameras and
printers.
The single chip MARVELL 88W8787 interfaces directly with both the RF and digital signals.
It transmits and receivers RF signals at 2.4GHz to and from the antenna and digital signals
to and from the host interface. A power management (PMU) is placed in the off Board to
provide power for all components in the module and also can save precious board space.
To maximize performance between WLAN and Bluetooth, three antennas will be required.
Two antennas are dedicated to the WLAN interface to provide diversity. The third antenna
will be dedicated for Bluetooth.

3.3 Mechanical outline Drawing
The WiFi module needs to be as small as possible. The target size of the module is 30mm x
15mm. We also want the height of the module to be as low as possible.
PCB: FR4, 4layers, single side design
Module size (W×L): 15mm ×30mm.
3.4 Software Requirements
All software components and documentation, including user interface and help files are
English version. For others language support need to be decided by mutual discussion.
3.4.1 Software setup
1. The whole software must be able to be installed by Device Manager or a
proprietary installer. Consequently, the software package must be either of the
followings:
A bunch of files, consisting of an .inf file or more and some other files that are
associated to the .inf file(s), so that Device Manager installs the whole software.
For avoidance of question, the .inf file covers up to application if attached.
An installer for installing the whole software. For avoidance of question, the
installer covers down to .inf file.
2. If installer or uninstaller is provided, it must be able to be run from command line
and must have silent mode option. For avoidance of question, this is not to
require eliminating normal (interactive) mode.
3. Setup should have ability to detect the presence of the preloaded files

3.4.2 Operating System Support
The driver must support the following Operating Systems at product introduction:
Linux, Microsoft Windows XP, Vista and Win7 drivers.
3.4.3 Software Functions
The software must support the following functions:
Auto scan to find AP nearby and show signal strength for each channel.
Support WPA, WPA-PSK, WPA2, WPA2-PSK, WEP 64bit & 128bit, IEEE
802.11x, IEEE 802.11i
Easily use software to upgrade from BTv2.1+EDR to BTv3.0 + HS
4. Compatibility and Certification Requirements
The 802.11b/g/n module shall pass the standard test plan, which includes hardware
compatibility and reliability, and software compatibility test.
FCC Compliance
One of the main reasons for considering a PWB module is that customer prefers to have
the ODM supplier perform FCC Part 15B and 15C (15.247) for 2.4GHz. The module is
being considered for multiple products. The customer is responsible for FCC Part 15B
product compliance testing.
Wi-Fi Certification
It is understood that Wi-Fi Certification is a system responsibility, however, the customer
would really like to have the ODM supplier consider performing this service, or at the very
least aid with testing.
5. Product Quality
The product quality must be followed-up by Foxconn factory quality control system.
6. Environmental Requirements
6.1 Temperature
6.1.1 Operating Temperature Conditions
The product shall be capable of continuous reliable operation when operating in ambient
temperature is 0 to +70.
6.1.2 Non-Operating Temperature Conditions
Neither subassemblies shall be damaged nor shall the operational performance be
degraded when restored to the operating temperature when exposed to storage
temperature in the range of -10 to +85 .
6.2 Humidity
6.2.1 Operating Humidity Conditions
The product shall be capable of continuous reliable operation when subjected to relative
humidity in the range of 5% and 95% non-condensing.
