LimeNET Micro makes deploying wireless networks more accessible than ever before, by extending the LimeNET line of integrated hardware solutions via an ultra-low cost platform that is capable of supporting narrowband systems, such as GSM and IoT wireless standards, in a stand-alone configuration.

 

As with existing integrated LimeNET platforms, the new LimeNET Micro is built on the very same revolutionary field-programmable RF (FPRF) technology and features the LMS7002M transceiver at its heart. However, this highly cost-optimised, single board solution also integrates GPS for high-accuracy timing, active Power-over-Ethernet (PoE), and embedded compute for fully standalone operation.

 

In utilising the Raspberry Pi Compute Module 3+, LimeNET Micro builds on previous platforms to further democratise wireless networks in much the same way that the Raspberry Pi has democratised embedded computing.

 

Given its incredibly low price point and highly integrated nature, there are endless application possibilities for LimeNET Micro, ranging from cellular networks and IoT, through spectrum monitoring, test and measurement, amateur radio, and radio astronomy.

 

 

Example Use Cases :

• Inexpensive enterprise and personal networks
• Rural, autonomous, and resilient networks
• Universal IoT communications hubs
• Rapid deployment infrastructure for emergency response
• Remote radio solutions for amateur radio and radio astronomy
• Integration into application-specific RF appliances
• Radio spectrum survey
• Passive wireless geolocation
• PHY and security research
• RF-aware robotics
