4. Overview
Node B is the European Technical Standards Institute’s (ETSI) name for the radio base
station. The basic function of the Node B is to convert 100 Base T packet data into the
UTRAN TD-CDMA air interface used between the Node B and the 3G Modem. The Node B
can be configured to operate in configurations ranging from a single sector or omni mode, up
to a 6 sector arrangement. One Node B is required for each sector of coverage, in the case
of an omni configuration one Node B will be required. The Node B is controlled by an INC
(Integrated network Controller) generally co-located at the site possibly in a separate
cabinet.
The Node B supports both 768 mega chips (10MHz) and 385 mega chips (5MHz) without
any hardware modification.
