6LoWPAN, Bluetooth LE, ANT+, GPRS, WIFI, DSL, IP ?

Router, nodes, … this came in today

“Harald, the term “router” you are using, would also mean WiFi Access Point , would it not?
and the topology here would be a star network, correct? with “router” as a star in this architecture.
there is no interconnection between “nodes” , correct

Right now I am talking about different technologies to different people for different applications.

6LoWPAN

  • IP riding on 868/915 MHz
  • Meshed or star network or peer to peer
  • Low power on battery
  • Can be addressed by any IP based device like PC, laptop, PDA or smartphone on any operating system from any corner in the world

ANT+

  • Proprietary protocol, popular in sport and medical apps
  • Riding on 2400 MHz
  • Meshed or star network or peer to peer
  • Ultra Low power con cell battery
  • Can be addressed by ANT+ in smartphones, dongle for iPhone, USB dongle, SD card or mini SD card

Bluetooth Low Energy

  • Protocol of Bluetooth SIG, would like to be popular in sport and medical apps
  • Riding on 2400 MHz
  • Star network or peer to peer (no meshed network)
  • Ultra Low power con cell battery
  • Can be addressed by nothing for now, because there are no smartphone or laptops for now.
    (Evaluation kits simulates the master = smartphone)

GPRS router

  • Based on embedded Linux
  • Quad band GPRS module
  • 6LoWPAN link by UART or Ethernet (UART is the cheapest)
  • Several UARTs, USB, I/Os, PWM …

Router / node

  • GPRS router or router in 6LoWPAN or ANT+
  • Node = 6LoWPAN or ANT+ or Bluetooth Low Energy
