Although the PC Card may still operate in the range of -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 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 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.
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 PC 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.
