Data from an arduino to be transferred to COSM through wireless internet

arduinowireless

I am trying to collect data from sensors through an arduino and send it over to the COSM server. My main problem is that the arduino will be in an environment where it will be impossible for me to provide an internet router and thus must find a way in which i can send the data to the internet through a wireless connection.

I would appreciate it if you could give me an answer that does not involve using a wifi shield coupled with data connection through a cell phone as i want it to run even in the absence of cell phone data packets.

Given the constraints specified in the question, here are a couple of data communication options:

  1. Zigbee module connected to the Arduino, in End Device mode, another Zigbee module in Coordinator mode on a PC connected to the wired network: 802.15.4 protocol, 250 Kbps speed (2.4 GHz modules), 10 to 50 meters range, 75 meters if you are lucky
  2. Bluetooth module or shield on Arduino, Bleutooth on a PC connected to the wired network: 802.15.1 protocol, 1 MBPS (non EDR) speed, 10 meters range

Other options include IrDA, which has much greater data rates, but range of a couple of meters - Good for an RFI-heavy environment where the RF solutions fail. Then there are RF data modules such as the nrf24l01+ wireless transceiver that can be considered as well.

Without desired cost, data rate and range constraints, a more specific answer may be difficult to put together.

I am refraining from suggesting smoke signals, Ouija boards, or a graduate student tasked with transcribing data into a data entry screen.
