Introduction to the Raven X
Rev 3.0 Mar.12 15
UMTS
UMTS (Universal Mobile Telecommunications System) supports data transfer
rates of up to 1920 kbit/s; most users can expect performance up to 384 kbit/s. A
UMTS network uses a pair of 5 MHz channels: one in the 1900 MHz range for
uplink, and one in the 2100 MHx range for downlink.
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 X will fall-back to GPRS for the
connection to TELUS to provide continued connectivity.
GPRS
General Packet Radio Service (GPRS) is packet-switched with many users
sharing the same tranmission 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 use where users only send or receive data intermittenly. GPRS
provides speeds of 30 - 70 kbps with bursts up to 170 kbps.
Connection Methods
You can connect the Raven X to an Ethernet (RJ45) port on a computer. When
connected to an Ethernet port, the Raven X behaves like a network card.
Networking
IPsec
The IP protocol that drives the Internet is inherently insecure. Internet Protocol
Security (IPsec), which is a standards-based protocol, secures communications
of IP packets over public networks.
IPsec is a common network layer security control and is used to create a virtual
private network (VPN).
The advantages of the IPSec feature includes:
• Data Protection: Data Content Confidentiality allows users to protect their
data from any unauthorized view, because the data is encrypted (encryption
algorithms are used).
