The basic parts of an LTE base station include the baseband part, which handles data processing and signaling and decides the capacity of the system, and the radio part, which converts digital data into RF signals, filters, and amplifies the RF signal, and decides the coverage of the system.
LTE Network Equipment includes: the baseband part, which handles data processing and signaling and decides the capacity of the system, the radio part, which interconverts digital data and RF signal, filters and amplifies the RF signal, and decides the coverage of the system, and the antenna, which transmits and receives RF signal and decides the ‘Shape’ of the coverage. The baseband part and radio part are the essential parts of the LTE eNodeB.
A BS Type 1-H base station shall be tested at the emission end of every TAB antenna port according to its operating frequency band. 6.1.1.1.2.2 The channel bandwidth and subcarrier spacing shall be defined in normal environment and voltage according to Table 35.
4 dBm (note 1) Note 1: The requirement is not applicable when Δfmax< 10 MHz. Note 2: The test requirements are originated from the basic limits. The proportional factor (difference between conducted & radiation), which is 9 dB, has be incorporated and applies to any test tolerance.
