Introduction to the Raven
address for your modem, you can use a Dynamic DNS service (such as IP Manager) to translate your IP address into to a domain name.
Caution: If you want to connect remotely to your Raven using TCP/ IP, the IP address given to your modem by your cellular provider cannot be a private or internal IP address (such as a custom APN or special private network) unless you are on the same network or inside that network’s firewall (such as with frame relay).
EDGE Communication
GSM Networks use SIM cards which are smart cards containing the account holder’s details. A SIM can generally be moved from one device to another allowing for account porta‐ bility and flexibility.
EDGE
EDGE (Enhanced Data rates for GSM Evolution) provides end‐ to‐end packet data services with an enhanced connectivity building on GPRS technology and using the established GSM networks. EDGE provides higher transmission rates and better transmission quality for data than GPRS. EDGE can carry data at speeds typically up to 384 kbit/s in packet mode.
When EDGE is not available, your Raven will fall‐back to GPRS for the connection to your cellular provider to provide continued connectivity.
GPRS
General Packet Radio Service (GPRS) is packet‐switched with many users sharing the same transmission channel, but only transmitting when they have data to send. This means that the total available bandwidth can be immediately dedicated to those users who are actually sending at any given moment, providing higher utilization where users only send or receive data intermittently. GPRS provides speeds of
