Wireless radio card for embedded mobile applications
Optimized for embedded mobile applications, the LA-5127 Wireless Networker™ CompactFlash® radio card delivers the power of 802.11b/g wireless connectivity to application-specific enterprise, retail, medical and industrial devices and equipment. It offers the robust security such applications require, as well as low-power modes for longer battery life and load balancing to maximize bandwidth.
The card is built with a worldwide radio chipset, and OEM end-product development is backed by Motorola’s strong pre- and post-sales support. It comes with a complete software development kit, including API and drivers for Linux and Windows CE, which can be customized and ported to proprietary operating systems. Quite simply, the LA-5127 is designed for enterprise mobility with the OEM customer in mind.
Enterprise-class security on enterprise WLANs
Provide robust security in your wireless handheld and portable enterprise devices with the LA-5127 radio card. Advanced encryption and authentication features offer the data security for Linux and Windows applications required by standards such as HIPAA and Visa CISP, making the card ideal for use in medical and retail settings, or anyplace security is essential.
Wi-Fi CERTIFIED®, the LA-5127 is compatible with any Wi-Fi certified 802.11b/g wireless LAN, so you can be confident that products using the LA-5127 will work with the LANs most often found in enterprise, medical, retail and industrial environments.
Designed for mobility
The LA-5127’s high performance mobility features include exceptional throughput using dynamic load balancing for reduced latency and increased bandwidth; low-power modes to preserve battery life and pre-emptive roaming to allow users to transparently move anywhere within the secure wireless network. The unique self-hosted card architecture also reduces the host device’s workload and maximizes power savings while maintaining authenticated connectivity.
Its mobility features combined with its small footprint allow OEM customers to design truly mobile enterprise devices.
Accelerate time-to-market—now and in the future
Available uniquely to the OEM market, the LA-5127 comes with a comprehensive development kit and API. Your developers can easily customize and port the API and drivers for Linux and Windows CE to proprietary operating systems, and Motorola’s OEM support team can work directly with your designers. Motorola can help you leverage the LA-5127’s regulatory approvals by providing software to facilitate regulatory testing, uploading Motorola-proprietary information to labs and regulatory bodies and, in some cases, even using your antennas as part of our regulatory certifications.
The LA-5127 is based on a worldwide radio chipset, backed by multi-tiered pre- and post-design support. Motorola’s extensive regulatory and compliance process provides a limited modular approval with the card, which can significantly reduce regulatory and compliance testing requirements for the end-product. In some cases, end-products attain certification compliance by simply referencing the LA-5127—without additional testing.
The card’s hard MAC with on-board memory makes it easily upgradeable, with substantial memory for future features and functions, and the LA-5127 is the first of a family of Motorola wireless radios to be built on a common code base for ease of future product migration. This means you can leverage today’s driver development efforts for future adoption of new features and additional radio bands.
