Layer 1 - Calibration Table
Field Name Values Description
Sub Carrier Id
1-10 The subcarrier number.
Antenna Index
1-8 The number of the antenna element.
Tx Weight_I
Real elements of the vector used while transmitting to
control ACC spatial pattern. This data is returned as a
result of any of the calibration modes.
Tx Weight_Q
Imaginary elements of the vector used while transmitting
to control ACC spatial pattern. This data is returned as a
result of any of the calibration modes.
Rx Weight_I
Real elements of the vector used during Receive to
control ACC spatial pattern. This data is returned as a
result of any of the calibration modes.
Rx Weight_Q
Imaginary elements of the vector used during Receive to
control ACC spatial pattern. This data is returned as a
result of any of the calibration modes.
Layer 2 - Carrier Data
Field Name Values Description
Sub Carrier Number
/ Sub Carrier
1-2, 3-4, 5-6, 7-8, 9-10 These two fields identify the 10 subcarriers. You can
click on the pair of subcarriers to be enabled for this
BTS. Subcarriers are assigned in pairs, one for uplink and
one for downlink.
Access Channel
Checkmark or blank Access Code Channels: The ACC Channel occupies the
Code Channel with Walsh Index 0 configured on a
specified subcarrier frequency. Each checkbox indicates
which pair of subcarriers is used for the Access
Channel(s).
Broadcast Channel
Checkmark or blank Broadcast Code Channel: If the box is checked, then this
channel is used to broadcast BTS related information. If
left blank, then information is broadcast on the ACC
channel.
TDD Symmetry
Ratio
Symmetric
or
Asymmetric
Symmetric Ratio is 1:1. Asymmetric Ratio is 1:3. This
parameter determines the variable uplink and downlink
ratio in a TDD frame. If set to Asymmetric, the downlink
will have 3 times more bandwidth than the uplink. This is
sometimes desired due to the types of users on the
system, i.e., downloading files off the Internet.
Repeat Uplink Pkts
Checkmark or blank If the box is checked, this carrier will repeat uplink
packets.
Frequency
(Scroll Bar)
2.305 GHz - 2.359 GHz
2.40 GHz - 2.473 GHz
2.50 GHz - 2.595 GHz
2.602 - 2.686 GHz
Indicates the center frequency of the BTS transmit signal.
