General Information

The LTM-2000A is a dual-band (2.4GHz and 5GHz) module. The device is a highly integrated MIMO (Multiple In, Multiple Out) Wireless LAN (WLAN) USB 2.0 network interface controller complying with the IEEE 802.11n Draft specification 2.0. The LTM-2000A is targeted for all WLAN markets that can take advantage of the high throughput and extended range of Broadcom’s second-generation MIMO solution. With MIMO, information is sent and received over two antennas simultaneously using the same frequency band, thus providing greater range, and increasing throughput while maintaining compatibility with legacy IEEE 802.11a/b/g devices. This is accomplished by a combination of enhanced MAC and PHY implementations including spatial transmitter/receiver multiplexing modes and advanced DSP techniques to improve receive sensitivity.

Features

-Two-Stream spatial multiplexing up to 300Mbps.

-Supports MCS 0-15 modulation and coding rates.

-Supports 20MHz and 40MHz channels with optional SGI.

-Support for STBC in both Tx and Rx.

-Greenfield, mixed mode, and legacy modes supported.

-Full IEEE 802.11a/b/g/ legacy compatibility with enhanced performance.

-Supports one USB 2.0 host port.

-Comprehensive wireless network security support that includes WPA, WPA2, and AES encryption/decryption coupled with TKIP and IEEE 802.1X support.

Applications

-Wireless client cards for desktop and notebook applications.

-High-performance IEEE 802.11ac Draft access points, routers, and DSL gateway that feature the PCIe host interface.
