Since this document describes specific topics only and does not cover all the requirements completely, parties must confirm other requirements that are not described in this document with Toshiba. This document contains Toshiba confidential information. Parties should agree to handle this document with care.,Confidential,Antenna Requirements (BT Antenna),Selection of Antenna The Antenna must be chosen from the list, shown on this document. ODM shall select other vendors antennas if ODM can obtain the regulatory approval with the module to be used. In this case, ODM must discuss with Toshiba in advance. The ODM or Antenna vendor shall do the antenna tuning. If module with built-in antenna is used, the built-in Antenna shall be used as is. Criteria Antenna performance Coverage of Antenna should be In 2.4-2.5GHz, = 60% against -8dBi gain. The calculation of coverage shall be done as below.
