Generations
4th Gen The Wireless World Research Forum (WWRF) defines 4G as a
network that operates on Internet technology, combines it with other applications and technologies such as Wi-Fi and WiMAX, and runs at speeds ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks). 4G is not just one defined technology or standard, but rather a collection of technologies and protocols to enable the highest throughput, lowest cost wireless network possible.

GSM and CDMA
GSM Covered in virtually all parts of the
world Mature, more stable network with
robust features Less signal deterioration inside
buildings Talktime is generally higher Subscriber Identity Modules (SIM)
allows users to switch networks and handsets at will
interferes with some electronics, especially certain audio amplifiers
CDMA (IS-95) It can accommodate more users uses soft handoff, reducing the
likelihood of dropped calls has a well-defined path to higher
data rates are generally unable to roam
internationally Smaller market so features are
sometimes late in coming to CDMA devices
every time you subscribe with a new provider you must buy a new phone

Choosing a Cell Phone Service
Consumers choose a carrier based on coverage area, handsets available, and services provided.
There are typically two service options: A pay-as-you-go plan is a prepay system in
which you buy minutes up front that must be used in a given time frame
Service contracts are typically for two years and involve finding a plan that best matches your usage

Choosing a Cell Phone Service
Calling plan option variables: Whenever, or anytime, minutes with no time restrictions Weeknight minutes, typically Monday through Friday, 9:00 p.m. to
5:59 a.m. or 6:59 a.m. Weekend minutes, typically Saturday 12:00 a.m. to Sunday 11:59
p.m. Rollover minutes are leftover unused minutes passed on from one
month to the next Mobile-to-mobile, or in-network calls refers to phoning other users
of the same carrier. Roaming refers to making calls outside the carriers coverage area
using another carriers network
