Radio Characteristics
Radio Characteristics
of TrueMobile 1150 Mini PCI Cards may vary:
According to the country where the product was
purchased.
According to the type of product that was purchased.
Wireless communication
is often subject to local radio regulations. Although TrueMobile 1150
wireless networking products have been designed for operation in the license-free 2.4 GHz
band, local radio regulations may impose a number of limitations to the use of wireless
communication equipment.
To comply with such
regulations, TrueMobile 1150 Mini PCI Cards are marketed with
dedicated channel-sets with a number of factory-programmed channels identified by the
following acronyms:
ETS for countries that adhere to the regulations as
defined by the European Telecommunications Standards Institute (ETSI).
FCC for countries that adhere to the regulations as
defined by the US Federal Communications Commission (FCC).
FR for France
JP for Japan

The
range of your wireless devices can be affected when the antennas are placed near metal
surfaces and solid high-density materials.
Range
is also impacted due to "obstacles" in the signal path of the radio that may
either absorb or reflect the radio signal.
In Open Office environments,
antennas can "see" each other, i.e. there are no physical obstructions between
them.
In
Semi-open Office environments, work space is divided by shoulder-height, hollow wall
elements; antennas are at desktop level.
In Closed Office environments, work
space is separated by floor-to-ceiling brick walls.
Supported Frequency Sub-bands
Subject to the radio
regulations that apply in your country, your TrueMobile 1150 Mini
PCI Card may support a different set of 2.4 GHz channels (see table below).
Consult your Authorized TrueMobile 1150 Reseller or Dell Sales office for information
about the radio regulations that apply in your country.

When installing
TrueMobile 1150 Mini PCI Cards the channel configuration is managed as follows:
For TrueMobile1150 Mini PCI Cards installed into wireless clients that operate in an "Peer-to-Peer" mode, the Mini PCI Card will default use channel 10.
