Cellular broadband

Cellular phone towers are very widespread, and as cellular networks move to third generation (3G) networks they can support fast data; using technologies such as EVDO, HSPA and UMTS.

These can give broadband access to the Internet, with a cell phone, with Cardbus, ExpressCard, or USB cellular modems, or with cellular broadband routers, which allow more than one computer to be connected to the Internet using one cellular connection.

Advantages and Disadvantages

Disadvantages:
# Unreliable: drop-outs are common during travel and during inclement weather
# Not a truly nationwide service
# Speed can vary widely throughout the day, sometimes falling well below the 400 kbit/s target during peak times.
# Asymmetric service: the upload rate is always much slower than the download rate.
# High latency compared to wired broadband (DSL and Cable) services.
# Often more costly compared to other methods

Advantages:
# The only broadband connection available on many cell phones and PDAs
# Mobile wireless connection to the Internet
# Available in all metropolitan areas, most large cities, and along major highways .
# No need to aim an antenna in most cases
# The antenna is extremely small compared to a satellite dish
# USB connection.
# Low latency compared to satellite Internet
# Higher availability than WiFi "Hot Spots"
# A traveler who already has cellular broadband will not need to pay different WiFi Hot Spot providers for access.
