LoRa Modulation Technique The iM980A uses Semtechs LoRa proprietary spread spectrum modulation technique. This modulation, in contrast to conventional modulation techniques, permits an increase in link budget and increased immunity to in-band interference. It achieves sensitivities 8 dB better than FSK modulation. LoRa also provides significant advantages in both blocking and selectivity, solving the traditional design compromise between range, interference immunity and energy consumption. 3.1 Channel Frequencies The iM980A uses the following channel set up specified by LoRaWAN [2]:

Uplink (Tx) 64 channels numbered 0 to 63 utilizing LoRa 125 kHz BW varying from DR0 to DR3, using coding rate 4/5, starting at 902.3 MHz and incrementing linearly by 200 kHz to 914.9 MHz Uplink (Tx) 8 channels numbered 64 to 71 utilizing LoRa 500 kHz BW at DR4 starting at 903.0 MHz and incrementing linearly by 1.6 MHz to 914.2 MHz Downlink (Rx) 8 channels numbered 0 to 7 utilizing LoRa 500 kHz BW at DR8 to DR13) starting at 923.3 MHz and incrementing linearly by 600 kHz to 927.5 MHz 3.2 Data Rates and Spreading Factors The iM980A uses the following data rates and spreading factors specified by LoRaWAN

Module Interface Characteristics 6.1 Programming Interface For programming the module with special firmware versions, there are two types of interfaces supported: A SWD-interface, which require a special programmer, as well as a bootloader-interface, for updating the modules firmware via UART-interface. Note: The module offers some IOs that are connected to the JTAG On-chip Debug system. Currently this interface is unavailable1. 1 Currently there is a silicon limitation for the MCU of the module.

Integration Guide The iM980A provides 32 connectors as described in Chapter 5. For integrating the iM980A into an environment, a typically circuit as given in Chapter 7.1 can be used. While designing the PCB Layout, the recommendations of Chapter 7.2 should be applied, as well as the recommendation for soldering in Chapter 7.3. 7.1 Typical Application Schematic Figure 7-1: Typical Application Schematic for iM980A iM980A_Datasheet.docx, Wireless Solutions, v1.0 Page 16 WiMOD iM980A Datasheet Integration Guide 7.2 PCB Design Recommendation The Top Layer of the carrier board should be kept free of Tracks and Vias under the iM980A because there are some test pads on the bottom side of the module which are not covered by solder resist. All GND pads of the module should be connected via low impedance path to GND. The iM980A's RF interface is already matched to 50 By using an adequate 50 antenna, no additional matching components are required1. For an ideal signal transmission between the modules RF pad and the antenna, the transmission line should be as short as possible and represent an impedance of 50 . Note: Disregarding this recommendation can affect the RF performance respective RF output power, sensitivity, and unwanted emissions. This impedance depends on frequency and PCB structure. It is recommended to use a grounded coplanar waveguide (CPWG) structure, to reduce effects of electromagnetic fields. The impedance of transmission line for grounded CPWG is basically affected by height H and material of the substrate, gap G between transmission line and ground on the top layer, as well as width W and thickness T of the transmission lines (Figure 7-2). Figure 7-2: Structure of a grounded CPWG 1 In other case a special matching network is required iM980A_Datasheet.docx, Wireless Solutions, v1.0 Page 17 erGNDGNDGNDRFHGGWTT WiMOD iM980A Datasheet Integration Guide Assuming a frequency of approx. 915 MHz, FR4 (er4.8) as substrate material, copper as conductor material, G = 0.4 mm and T = 35 m, the width of transmission line is given by Table 7-1.
