5.4 TRANSMIT/RECEIVE ANTENNA REQUIREMENTS
The ideal antenna is a ceramic patch that has left hand circular polarization. This antenna should have a gain of between -1dB
and 5.1dB in the spatial area between 25 degrees and 90 degrees elevation. A candidate antenna meeting these requirements
is the TAOGLAS SP.1615.25.4.A.02.
The ST150M has Modular Certification from the FCC (USA) and Industry Canada (Canada) when used with an antenna that
meets the specifications above. This means that, in general, no further FCC Part 25 testing or IC testing is required when using
an approved antenna in accordance with the Globalstar-specified implementation requirements listed in this document. Note
however, that regulatory requirements are subject
to change at any time, and it is the responsibility of the integrator to ensure that the product is fully compliant with all applicable
regulations in whatever markets the integrator is selling the product.
Final installation must be in compliance with 25.213. The antenna installation and operating configuration of this transmitter
must satisfy MPE categorical Exclusion Requirements of 2.1091. The antenna used for this transmitter must be installed to
provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any
other antenna or transmitter.
5.5 BLE ANTENNA REQUIREMENTS
Globalstar recommends the following antenna, or similar, for optimal BLE performance:
Manufacturer: Pulse Larsen Antennas Part Number: W3008C
Frequency: 2400-2483.5MHz
Max Gain: +1.3 dBi
Nominal Impedance: 50
Ω
Power Handling: 5W
NOTE:
it will be the responsibility of the VAR/developer to ensure the tuning of the Bluetooth antenna in its intended final
installation meets the tuning requirements for the end application.
5.6 SINGLE MODULAR APPROVAL REQUIREMENTS
The ST150M module provides surface mount pads for the RF output and BLE antenna which must be internally attached
passively via the PCB to the approved antennas (referenced above). No antenna connector or any other antenna may be used.
In order for any device to obtain certification from Globalstar for use under this modular approval, this condition must be met.
These requirements are enforced as part of the Globalstar Certification process whereby any device utilizing the ST150M
module must be submitted to Globalstar for approval prior to being approved for provisioning for operation on Globalstar's
network. Adherence to these requirements is an integral part of the Globalstar Certification process.
Since the intent of Globalstar Certification is to ensure that only Globalstar approved antennas are used, the Globalstar
certification and provisioning process constitutes a more stringent enforcement of sections 15.203, 15.204(b), 15.204(c),
15.212(a), and 2.929(b) than merely requiring a "unique connector".
In summary, Globalstar will not certify ANY device using the ST150M module UNLESS the approved layout and antennas for
satellite and BLE transmission are passively connected to the ST150M on a single circuit board. This meets the requirements of
the aforementioned part 15 clauses.
