The Cisco AIR-LMC352 is a PCMCIA network card for use in notebooks and compatible Pocket PCs. It enables connection to wireless networks according to the 802.11b standard in the 2.4-GHz frequency range (2400–2483.5 MHz) with a maximum data rate of 11 Mbit/s. The card is designed as a 16-bit PC Card (PCMCIA Type II) and operates at a supply voltage of 5.0 V ±0.25 V, making it usable even in older devices without CardBus support. The physical dimensions are 8.56 cm × 5.41 cm × 0.51 cm.

Applications

The AIR-LMC352 is designed for mobile access to wireless networks in office environments, during travel, or in facilities with existing WLAN infrastructure. It is particularly suitable for older notebooks and Pocket PCs equipped with a PCMCIA slot. Compatibility with devices such as the HP Ipaq h3950 and h5550 (with PCMCIA jacket) is explicitly mentioned, highlighting its use in mobile work environments.

Functions and Features in Detail

The card features two MMCX connectors (Mini MCX) intended for connecting external antennas. The receiver sensitivity is –91 dBm at 1 Mbps, –89 dBm at 2 Mbps, –87 dBm at 5.5 Mbps, and –86 dBm at 11 Mbps, enabling stable connections even at low signal strength. The transmit power is 100 mW. The card supports 128-bit WEP encryption as well as WPA to secure data transmission. Two LEDs (green and orange) serve as status indicators for connection and activity.

Technology Explained Simply

The modulation techniques include BPSK for 1 Mbps, QPSK for 2 Mbps, and CCK for 5.5 and 11 Mbps, enabling data transmission according to the 802.11b standard. Power consumption is 280 mA (typically 250 mA) in receive mode and 10 mA in sleep mode, highlighting energy efficiency. The operating temperature range is 0 °C to 70 °C, and the storage temperature range is –40 °C to +85 °C. The card is therefore designed for indoor use under normal operating conditions.

Compatibility and Accessories

The AIR-LMC352 is compatible with a wide range of operating systems, including Windows 95/98/ME/NT/2000/XP, Linux, Windows CE 2.x, 3.x, 4.x, and PocketPC (Windows Mobile) 2000/2002/2003. Drivers are available for these systems. As an alternative, a PCI card designated AIR-LMC352 is offered, suitable for desktop systems.

Installation and Mounting

Installation is performed by inserting the card into a free PCMCIA slot in the device. Driver installation is carried out using the provided driver files, which are available for the specified operating systems. No special mounting or additional tools are required.

Operational Advantages

The card provides a reliable WLAN connection for older devices lacking integrated wireless functionality. Support for WPA and 128-bit WEP ensures adequate protection for data transmission. Low power consumption in sleep mode extends battery life in mobile devices.
