GE MDS SDM9-1 Radio Module
Product Information
SDM9-1 Radio Module
The SDM9-1 Radio Module is a Part 24 or Part 101 device designed to operate in the 928-960MHz band. It is intended for use in fixed installation applications and is compatible only with the GE MDS Master Station Chassis. The module and chassis are designed for operation from -40 to +60C and are not intended for outdoor use. The output power is configurable up to +40dBm, and it must be adjusted to accommodate antenna gain to conform to the specific ERP limits of the FCC licensee using this product. The SDM9-1 Radio Module features a unique edge connector and thermal transfer apparatus that is only presented by the GE MDS Master Station. The GE MDS Master Station provides a fixed 24V power source and data interfaces through the card edge connector to enable module operation. Heatsinking is provided through a thermal connector that engages with the chassis heatsink when the module is installed in the chassis. RF exposure considerations are important when using this product, as it emits radio frequency energy. Persons may not come closer than 1.7 meters to the front of the antenna when the transmitter is operating with a 7dBd (9.15dBi) gain antenna. The conducted output power of the host chassis is up to +40dBm, and this module and the host chassis are intended for professional installation only.
Product Usage Instructions
SDM9-1 Radio Module
To use the SDM9-1 Radio Module, follow these instructions:
- Ensure that you have a GE MDS Master Station Chassis that is compatible with the SDM9-1 Radio Module.
- Install the SDM9-1 Radio Module in the chassis, ensuring that the thermal connector engages with the chassis heatsink.
- Select an appropriate antenna for use with the module and configure the output power to accommodate the antenna gain, ensuring that it conforms to the specific ERP limits of the FCC licensee using this product.
- Ensure that the module and chassis are used in fixed installation applications only, and are not intended for outdoor use.
- Ensure that persons do not come closer than 1.7 meters to the front of the antenna when the transmitter is operating with a 7dBd (9.15dBi) gain antenna. Use of higher gain antennas means increasing the distance accordingly.
- Ensure that the product is installed by a professional, as it is intended for professional installation only.
Regulatory Information for Limited Modular Use
Applicable FCC Rules
This module is designed as a Part 24 or Part 101 device operating in the 928-960MHz band as detailed in Table 1 of this document.
Operational use conditions
This module may only be used with the GE MDS Master Station Chassis. This module is intended for use in fixed installation applications only. The module and chassis of this product are designed for operation from -40 to +60C and is not intended for outdoor use. This device is for professional installation only. Output power is configurable up to +40dBm and must be adjusted to accommodate for antenna gain to conform to the specific ERP limits of the FCC licensee using this product.
Limited Module Host restrictions
The SDM9-1 radio module features a unique edge connector and thermal transfer apparatus that is only presented by the GE MDS Master Station. The GE MDS Master Station provides a fixed 24V power source and data interfaces through the card edge connector to enable module operation. Heatsinking is provided through a thermal connector that engages with the chassis heatsink when the module is installed in the chassis.
Trace antenna designs
The SDM9-1 does not include any trace antenna designs, and therefore there are
no applicable considerations for this topic.
RF exposure considerations
The radio equipment described in this operation emits radio frequency energy.
The concentrated energy from a directional antenna may pose a health hazard.
Persons may not come closer than 1.7 meters to the front of the antenna when
the transmitter is operating with a 7dBd (9.15dBi) gain antenna. The use of
higher gain antennas means increasing the distance accordingly.
Antennas
The conducted output power of the host chassis is up to +40dBm. This module and the host chassis are intended for professional installation only, and the licensee is responsible for antenna selection and associated output power configuration to adhere to applicable limits under the rules or license to which they are operating.
SDM9-1 Radio Module Theory of Operation
Labeling and Compliance
Figure 15, below, is an example of the label that must be present on the Host:
GE MDS Master Station Chassis as shown in Figure 16. This label is installed
at the factory during production.
above MPRS Master Station product label showing “Contains SDM9-1” along with FCC ID.
The location of the label is detailed in Figure 15, as placed on the Master Station chassis
Test Modes
The Master Station chassis does not externalize module operational test modes to the end user. Test and alignment are performed during production calibration as described in “SDM9-1 Factory Alignment Procedure”. Prior to product shipment, GE MDS performs a series of tests in the production environment to ensure that the completed assembly is operating satisfactorily.
Additional testing for Part 15 Subpart B
The GE MDS Master Station Chassis is the only permissible host for the SDM9-1.
GE MDS ensures that the Master Station Chassis complies with FCC Part 15
Subpart B when operating with the SDM9 radio module in place.
EMI Considerations
The SDM9-1 Radio Module includes integrated shielding for the RF section, and
entire module shielding to cover all components on the PCB. This module
conforms to all applicable Part 15, Part 24, and Part 101 requirements without
needing to be installed inside of the host enclosure. The Master Station
chassis does not allow multiple modules to operate simultaneously,
Changes
GE MDS does not offer for sale the SDM9-1 as a standalone device for
integration with other hosts. As the grantee of the host and this module, GE
MDS does not have any additional guidance or technical contacts for third-
party entities to create such products.
