non-voice data; most 3G networks use WCDMA.
3.5G: A more recent standard of mobile networking technology; generally uses HSDPA.
3.75G: A more recent standard of mobile networking technology; generally uses HSUPA.
4G: A more recent standard of mobile networking technology; generally uses LTE.
APN (Access Point Name/Network): Provides GPRS routing information. Consists of:
Network ID: Identifies the external service requested by a GPRS user.
Mobile network operator ID: Specifies routing information.
ARFCN (Absolute Radio Frequency Channel Number): The specific ID numbers for all radio channels
used in cellular mobile communications.
bps (bits per second): How data flow is measured.
CHAP (Challenge Handshake Authentication Protocol): CHAP identifiers are changed frequently
and authentication can be requested by the server at any time.
DNS (Domain Name System): Helps routing network traffic by making the addressing process more
user-friendly.

intensive data at up to 5.76Mbps; typically associated with 3.75G.
HSPA+ (High Speed Packet Access +): This is also known as HSPA Evolved, is the next step and is
more focused on delivering data services enabling speeds of up to 42Mbps in the downlink
and 11Mbps in the uplink.
IMEI (International Mobile Equipment Identity): A number unique to each GSM/UMTS device that
