Наименование: Беспроводной адаптер Cisco AIR-RM20A-A-K9 802.11a/b Cardbus Radio Network Expansion Module/w Dual Int AntFCC

Производитель: Cisco

Модель: AIR-RM20A-A-K9

The Cisco Aironet® 1100 Series offers customers an affordable, easy-to-install, single-band access point that features enterprise-class management, security, and scalability. Legacy Cisco Aironet 1100 Series access points have an 802.11b radio that may be field-upgraded to 802.11g; alternately, the Cisco Aironet 1100 Series may be ordered with a single 802.11g radio that is backward-compatible with 802.11b.

Key Features

• Single 802.11b or 802.11g radios available; 802.11b is field upgradable to 802.11g

• Provides end-to-end solution support for Intelligent Network Services

• Variety of mounting options

• With the IEEE 802.11g version, up to 54 Mbps data rates while maintaining full backward compatibility with legacy 802.11b devices

• Provides administrators configuration control to support both 802.11g and legacy 802.11b clients

• Cisco IOS Software operating system provides a familiar user interface

• Integrated diversity dipole antennas

• WiFi-Certified
