Mounting the Antenna Because the PCI card is a radio device, it is susceptible to RF obstructions and common sources of interference that can reduce throughput and range. Follow these guidelines to ensure the best possible performance: • Place the PCI card's antenna in an area where large steel structures such as shelving units, bookcases, and filing cabinets will not obstruct radio signals being transmitted or received. • Place the antenna away from microwave ovens and 2.4- and 5.8-GHz cordless phones. These products can cause signal interference because they operate in the same frequency range as the PCI card. 1-14 Cisco Aironet 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) Installation and Configuration Guide for Windows Vista OL-16534-01

Mounting the Antenna
Because the PCI card is a radio device, it is susceptible to RF obstructions and common sources of
interference that can reduce throughput and range. Follow these guidelines to ensure the best possible
performance:
•
Place the PCI card’s antenna in an area where large steel structures such as shelving units,
bookcases, and filing cabinets will not obstruct radio signals being transmitted or received.
•
Place the antenna away from microwave ovens and 2.4- and 5.8-GHz cordless phones. These
products can cause signal interference because they operate in the same frequency range as the PCI
card.
