Also, while RSCP can be measured in principle on the downlink as well as on the uplink, it is only defined for the downlink and thus presumed to be measured by the UE (User Equipment) and reported to the Node B. While RSCP can be defined generally for any CDMA system, it is more specifically used in UMTS. RSCP is also called Receiver Side Call Power. HSDPA merupakan evolusi dari standar W-CDMA dan dirancang untuk meningkatkan kecepatan transfer data 5x lebih tinggi. In CDMA systems, a physical channel corresponds to a particular spreading code, hence the name (Received signal code power). High-Speed Downlink Packet Access (HSDPA) adalah sebuah protokol telepon genggam dan kadang kala disebut sebagai teknologi 3,5G. It is used as an indication of signal strength, as a handover criterion, in downlink power control, and to calculate path loss. For example, the received value can be used to trigger some action on the Arduino module.In the UMTS cellular communication system, Received Signal Code Power (RSCP) denotes the power measured by a receiver on a particular physical communication channel. The following extract denotes the part corresponding to receiving downlink messages. Các trng thái ca RRC trong HSDPA-HSUPA.jpg 808 × 429 54 KB Hinh.A HSDPA.png 768 × 480 12 KB Hinh.B HSDPA. As an adverb downstream is following the path of a river or stream. If you want to provide a separate downlink, make up a (long, secure, random) token and specify it as the downlink-key. Category:High-Speed Downlink Packet Access From Wikimedia Commons, the free media repository Media in category 'High-Speed Downlink Packet Access' The following 17 files are in this category, out of 17 total. In order to configure the Autonomo with LoRaBee device, you can refer to Deploying an End-to-End LoRaWAN Platform. As an adjective downstream is lower down, in relation to a river or stream. One advantage of such device is that it can be powered by a smartphone-sized solar panel. According to, Autonomo is a matchbox-sized powerhouse which uses the new Atmel Cortex M0+ 32bit micro controller. In the LoRaWAN platform, we support devices based on an Autonomo board with a LoRaBee Microchip RN2483 module. "data": "." // base64 encoded data (plaintext, will be encrypted by LoRa Server) "fPort": 10, // FPort to use (must be > 0) "confirmed": false, // whether the payload must be sent as confirmed data down or not "reference": "abcd1234", // reference which will be used on ack or error (this can be a random string) In order to send downlink data to a specific device, you should publish the encoded message in the corresponding topic application/APPLICATION_ID/node/DEVICE_EUI/tx as explained in the loraserver documentation: The APPLICATION_ID and DEVICE_EUI are those used in the configuration of your LoRaWAN application server as explained in ESIB IoT Challenge. You can also limit to the topic including the messages of any specific device: application/APPLICATION_ID/node/DEVICE_EUI/rx. If you want to receive all messages arriving at the backend, you can use the generic topic #. Start by configuring a new connection to the MQTT broker by simply adding the IP address of the broker in the Server URI field. You can use mqtt-spy to debug the messages received from the LoRaWAN devices. mqtt-spy is a JavaFX application, so it should work on any operating system with an appropriate version of Java 8 installed. It has been designed to deal with high volumes of messages, as well as occasional publications.

Mqtt-spy is an open source utility intended to help you with monitoring activity on MQTT topics. ![]()
