-20° to 70°C, operation outside the range of 0° to
55° C may no longer be according to specifications

Radio Characteristics
Radio Characteristics of TrueMobile 1150 PC 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 TrueMobile1150 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
PC 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, and
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 TrueMobile1150 PC Card may support a different set of 2.4
GHz channels (see table below). Consult your Authorized TrueMobile1150 Reseller or Dell Sales office for information
about the radio regulations that apply in your country.

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