Understanding Cellular Service
1xRTT
1xRTT (1 x Radio Transmission Technology) or ‘1X’ is a
digital cellular technology that offers the benefits of the
CDMA digital service and allows data to be sent faster.
Cells designed for use on the 1X network have enhanced
graphical capabilities and can download content, such as
ringtones and games.
EV-DO Rev A
The EV-DO Rev A network lets you use wireless data services
such as web browsing, content downloads, streaming video,
streaming radio, e-mail and instant messaging at speeds
close to residential high speed connections. The average
upload speeds are between 350 kbps and 550 kbps and peak
download speeds are between 2000 kbps and 2300 kbps.
CELLULAR COVERAGE
There are a number of factors that affect your cellular coverage:
•
The position of your cell. Your cell may have difficulty
receiving a signal if it is in the bottom of a bag or
briefcase, or if you are inside a building and especially
an elevator.
•
The antenna type (internal or external) and position
(retracted or extended, below or above the car dash).
•
Electronic devices, such as computer screens or electrical
appliances may interfere with the signal.
•
The battery charge.
•
The terrain/topography. A cellular signal will not follow
you into a valley and can be blocked by hills, buildings
and dense trees.
•
Atmospheric conditions, such as changes in the weather,
can affect your cellular service.
Tips for improving your cellular coverage:
•
Ensure your cell is in an upright position.
•
Turn off or move away from any electronic devices (such
as computer screens) that may be creating interference.
•
Make sure your battery is always charged up to at least
two bars on your battery indicator.
•
Try to move to an open area.
•
Try stepping outside to make a call.
•
Make sure the antenna of your cell is fully extended.
