Teensy

http://www.pjrc.com/teensy/td_serial.html
When transmitting, Serial.write() and Serial.print() group bytes from successive writes together into USB packets, to make best possible use of USB bandwidth. You can override this behavior using Serial.send_now(), but by default multiple writes are merged to form packets.

"Long-term, as in after the K66 board, I very likely may make a Teensy using one of those chips. I've been talking with NXP about future versions of that chip, but any info that's not yet on their website is covered by a NDA, so I really can't say anything more at this time. In the nearer term, I'm hoping to see a shield (made by a third party, not PJRC) with one of the mature Nordic chips and Lipo battery management...."

Tests I have done from a ground station to a high altitude balloon suggest that @ 1000bps 10mW will cover around 120km on simple 1/4 wave wires and 100bps will go around 300km.

"The gateway is based on iC880a LoRaWAN concentrator by IMST which uses Semtech SX1301 base band processor designed for use with LoRa™ networks. It is capable of supporting thousands of endpoints with eight simultaneous receive channels. The BeagleBone Green with 1GHz (2000 MIPS) processor and fully operational on fast SPI bus was chosen as a powerful control unit. The Mikrotik Routerboard providing the advanced settings of the communication functions on Ethernet serves as a communication gate with the Internet on TCP/IP. The installation in tandem with the suitable antenna on the appropriate Point of Presence (like telecommunications pylons, roofs of the buildings etc.) can establish bidirectional communication network which allows handling with thousands nodes up to several dozen kilometers."

If solder jumper J1 is not made, power for the RF switch is supplied via iMod port pin 10, marked VS on PCB. This is useful for very low power applications that want to save the 9 to 20uA supply current required by the RF switch. For these applications, power can be supplied(to iMod port pin 10) via a port pin on CPU only when transmitting or receiving.

AN1200.22 LoRa™ Modulation Basics

http://lorawan.blogspot.fr/

https://www.aruco.com/2015/12/sigfox-lora/
Aujourd’hui, un canal de fréquence de 200 kHz est utilisé par Sigfox, pour des messages de 100 Hz de largeur de bande. Cela correspond à 200 messages pouvant circuler en simultané depuis ou vers une station Sigfox (200 kHz x 100 Hz x 10% = 200, les 10% correspondant à la marge prise pour éviter les collisions). Les messages comportant 208 bits (sur 2.08s) et répétés trois fois, cela nous fait une capacité de 2,7 millions de messages par jour au maximum.

La technologie LoRa utilise 8 canaux de fréquence de 125 kHz dans la plage de fréquence 867 – 868,5 MHz. La capacité totale d’un réseau LoRa se juge par une agrégation de capacités par débit. Etant donné que différents débits sont proposés (correspondant à autant de spreading-factors SF), on obtient 138 000 messages par jour à portée maximale et 3.3 millions messages par jour à portée minimale.

Les réseaux LoRa permettent de mesurer un temps de propagation à une précision de l’ordre de 200ns, ce qui correspond à une précision à 60m sur la distance.
