Hardware Specifications

• Module Dimensions
• For SiP module, aiming for 10 x 10 mm.
• Other cards have standard sizes.
• IEEE Standard
• 802.11a (5 GHz / 54 Mbps)
• 802.11b (2.4 GHz / 11 Mbps)
• 802.11g (2.4 GHz / 54 Mbps)
• Data Throughput
• Usually constrained by host interface, CPU
  performance, radio, etc.
• 6 Mbps for 802.11b.
• 18-22 Mbps for 802.11a/g.
• Host Interface
• Communication between components on PCB and to
  the outside world.
• SDIO/SPI most popular for SiP modules.
• PCI Express for Mini Card.
• Chipsets
• Usually one CPU/BB/MAC/RF chip one RF Front-End
  Module chip.
• Operating Voltage
• Usually 3.3V vs. 1.8V.

• Power Consumption mW or mA
• Mobile device is very sensitive to power
  consumption.
• Transmit Power dBm
• Higher transmit power ? longer transmit distance.
• Higher transmit rate ? lower transmit power.
• Receive Sensitivity dBm
