I am planning to purchase the GPRS/GPS module for Arduino (http://www.libelium.com/tienda/catalog/product_info.php?cPath=21&products_id=42) but have a couple of questions I would be grateful if you could help me with:
Do I need to buy a GPRS antenna as well as a GPS antenna?
Will I be able to run this module with my Arduino board off a battery? If so, what type of battery?
Thanks in advance.
