915 MHz Wireless Module

Laird’ third generation 915 MHz FHSS module sets yet another standard for industrial RF communication. Based on proprietary FlexRF™ technology, this globally-accepted module will exceed most OEM application and performance requirements.

Embedded with Laird's robust server-client protocol, the LT1110 permits an unlimited number of clients to synchronize to a single server for low latency communications. The server and all clients in a network can communicate with any radio in range via either addressed or broadcast packets. The configuration and test software allows OEMs to design and test networks to suit their applications. From the OEM integrator’s point of view, the LT1110’s interface (API, configuration, etc) is 100% compatible with the LT2510 allowing the OEM to choose either 915 MHz or 2.4 GHz. The enhanced API commands provide packet routing control and network intelligence. With its field-proven proprietary FHSS RF protocol and increased penetration at 915 MHz, the LT1110 rejects RF noise, excels in multipath scenarios, allows for co-located systems, and provides an extremely reliable communication link.

The LT1110 achieves RF data rates up to three times faster than our previous generation 915 MHz transceivers. Two output power levels are available, a low power module with 8 dBm conducted output power and a high power with 23 dBm conducted output power. Line of sight communication up to ½ mile and 2 miles respectively, is possible while consuming as little as 32 mA of current in full transmit mode! It also comes with a modular approval allowing higher gain antennae to greatly increase the effective range. At the same time, a range of ultra-low power modes make the LT1110 your best solution for power-restrictive or battery-operated applications.

The mini SMT package is well-suited for space-constrained designs and has the same pin-out and mechanical form factor as the 2.4 GHz LT2510 module. It is available in pick-and-place packaging for volume manufacturing. A pluggable version with two single row headers is offered for ease of integration.

Flexible RF Protocol:

Embedded into Laird Technologies’ 900MHz and 2.4 GHz FHSS modules, FlexRF technology supports unrivaled flexibility in industrial wireless applications. OEMs have the ability to control and optimize both the radio module and the network, allowing them to develop a highly reliable system for their specific application.

Numerous “software hooks” empower, control, and provide flexibility. They allow designers to mold the communication link around applications, as opposed to squeezing the application into a fixed communication technology or standard. Each transceiver is designed to provide OEMs with a feature-rich, high-performance, configurable, secure, compatible, integrated solution, allowing OEMs to build the most optimized network possible.
