If you're using nRF24L01+ modules but need a lot more range, then these long range modules with external antenna from PMD Way will give you the extra distance. Instead of a tiny PCB-based antenna, these have a fully-external antenna - and combined with improved circuitry can give you up to 1000m in open air between two of the same modules. The Nordic nRF24L01 -a highly integrated, ultra low power (ULP) 2Mbps RF transceiver for the 2.4GHz ISM (Industrial, Scientific and Medical) band. Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. Features Worldwide license-free 2.4GHz ISM band operation 250kbps, 1Mbps and 2Mbps on-air data-rate options Enhanced ShockBurst™ hardware protocol accelerator Ultra low power consumption – months to years of battery lifetime Specifications Power supply : 1.9~3.6V IO port working voltage : 0~3.3V/5V Transmitting rate : +7dB Receiving sensitivity : ≤ -90dB Transmission range : 250m in open area Dimension : 41 x 15.5mm Interesting Arduino tutorial Working with Raspberry Pi Don't forget to check out our full range of nRF gear if this doesn't meet your needs.
