Smart rack for logistics system Descriptions Overview MA903A1 is an easy-to-integrate Access Point embedded module for hosting ultra-low-power wireless-link application. With state-of-the-art Platanus TM protocol and networking kit, large network (up to 16000 nodes) can be easily formed. Equipped with ISM-band RF operated at 868MHz/915MHz bands and popular ARM 32-bit MCU along with embedded flash memory and SRAM, MA903A1 is an ideal embedded solution for system integrator to develop wireless applications with no worry about design hassles, both wireless and networking. Easy to Integrate and Use Designed as the embedded module, MA903A1 has only the board area of 35.5mm x 37.5mm, compact enough for most embedded system design. A pre-matched 50 ohm port is ready to be used with on-board or external antenna. The RF matched network is calibrated to optimize the RF performance when the module is shipped, saving the design hassles for application designers. There are total 50 stamp pads on MA903A1 with multiple digital interfaces: UART, GPIOs, and JTAGS. This brings the design flexibility to end applications that MA903A1 is easy to interface with other LAN modules. Through the robust wireless link, controlled/collected information from End Device (ME10WM010) can be easily sent to the upper application layers and devices. Datasheet v1.0 MA903A1 2014/01 Copyright © by M 2 Communication Inc. Page 2 of 22 Ready-to-go Sub-GHz Radio Link with Excellent Reliability T he wireless link utilizes the sub-GHz radio band, requiring no special licenses (free-ISM) and certification. MA903A1 comply with the ETSI EN 300 220 and FCC part 15 regulations. Compared to the crowded 2.4GHz band, sub-GHz radio link, given the similar power level, allows better distance and penetration especially in the hostile indoor environment. In particular, with WiFi and Bluetooth crowding the 2.4GHz band these days, MA903A1 is immune from all 2.4GHz interference and delivers the reliable wireless link. With the data rate of 500kbps in 2FSK, the bandwidth use efficiency is 16x better than 2.4GHz Zigbee (2MHz). MA903A1 can deliver the link budget up to 107dB (TX maximum p ower: 11dBm, RX Sensitivity level: -96dBm) without adding external components. The Line-of-Sight (LOS) link distance is over 300 meters*. * tested with 63-byte payload with PER of 1%. This may be variable depending on test environment Robust Two-way Networking MA903A1 uses a built-in protocol Platanus TM to support “two-way” networking, saving the SI’s design headache of linking large amounts of wireless nodes. Used with ME10WM010 (End Device), MA903A1 can support two types of network hierarchies: STAR and TREE (as shown below). When MA903A1 is configured in STAR networking, up to 128 nodes can be supported. When MA903A1 is configured in TREE network, up to 16000 nodes can be supported. Asymmetrical downlink and uplink are supported to balance between network reliability and response time, and the programmable network parameters can be used to optimize for each use scenario. Figure 1. STAR configuration Figure2. TREE configuration Upper Layer Connectivity MA903A1 is shipped with the UART interface and the managing software library. Thus the upper-layer devices, such as TCP/IP gateway, can easily access MA903A1 in the network, as the Access Point to the private network, to exchange data “interactively” via the Ethernet or WiFi. This makes the cloud- based application developer easy to hook up with the privately-own network when building with MA903A1. Figure 3. Network Structure Datasheet v1.0 MA903A1 2014/01 Copyright © by M 2 Communication Inc. Page 3 of 22 Ideal Platform for Low-power Application Development MA903A1 is powered by ARM Cortex MCU with clock up to 32MHz with embedded 128K-Byte flash and 1M-Byte SRAM, to support built-in Platanus TM networking library from M2C and for peripherals. For details, please refer to the associated documentation. Using Platanus TM protocol with M2C MA903A1 (Access Point) and/or MR1001 (Router), the formed network can achieve ultra-low power consumption for battery-friendly applications. The network acts in the cellular-like behavior, with sleep time configurable from 5 seconds up to 90 seconds. Details of power consumption can be referred to the datasheet of ME10WM010.
