SARA-S200 - System Integration manual 1 System description Overview The U-blox SARA-S200 module is a cost effective solution intended for data throughput applications such as remote sensing that may require up to 100 kB per day. It features ultra-low power consumption mode for battery powered devices, and is suitable for applications that demand 10 years or longer field life on a single cell. The module's ultra-low -133 dBm Rx sensitivity permits cell sites to range typically between 50 and 200 sq miles. RPMA air interface characteristics RPMA Terrestrial Radio Access Time Division Duplex (TDD) operating mode Single-band support: ISM Band Proprietary RPMA Direct spread spectrum (DSSS).

10 Table 1: RPMA Air Interface characteristics SARA-S200 is strictly a data module for embedded solutions. The 7-wire SPI supports handshaking for deep sleep modes. Along with the module, there are host common libraries provided to enable easy adoption to existing host application processors. The SARA-S200 antenna interface is provided via 50 antenna pads with a main RF port and a diversity RF port to further provide improved RF performance. Architecture SARA-S200 . VCC_3V3.
