Phone (760) 444-3500 Fax (760) 444-3005 Report Number: 2012 01192228 ETSI2 Specification: EN 62311 (2008-01)) Section 2: Equipment Under Test 2.1 Samples Submitted for Assessment The following sample of the equipment has been submitted for type assessment: Sample No. Description Serial No. 9502 MACHINE-TO-MACHINE (M2M) TERMINAL NONE 2.2 Theory of Operation The 9502 is a Machine-to-Machine (M2M) Terminal. The 9502 comprises of a Transmitter in the frequency range 1631.8 MHz to 1660.2 MHz and 1668.3 MHz to 1674.5 MHz. The Hughes 9502 is a machine-to-machine (M2M) terminal for use in unmanned environments enabling packet data (e.g. oil pipeline telemetry) to be sent over Inmarsat’s BGAN (Broadband Global Area Network) constellation of three geo-stationary I-4 satellites which cover the globe – see Figure 2. The 9502 will also operate with Inmarsat’s new Alphasat I-XL extended L-band (XL) satellite when launched in 2013. The Hughes 9502 terminal operates as an Inmarsat BGAN Class 2 terminal. The Hughes 9502 terminal consists of an indoor unit (IDU) and an external passive antenna. A 10 meter RF cable is provided for connection between the antenna and IDU. Connectivity is provided by single Ethernet and USB ports. A remote terminal (e.g. with sensor interfaces) will send bursts of data to the 9502 IDU via the Ethernet port; the data will then be sent over the air via a BGAN satellite link. Only packet data service is allowed. The USB 1.1 port is provided for configuration of the terminal via a PC. An integrated SIM carrier enables the insertion of a customer-provided SIM card to gain access to authorized Inmarsat services. A GPS receiver in the terminal provides location information. An external customer provided GPS receiver can alternatively be connected to the 9502 IDU via the RS-232 port. Each Inmarsat satellite broadcasts: a single Global beam which broadcasts system information; 19 Regional beams which are used for access control; and around 200 Narrow beams which are used for data. The forward link (from the satellite) is TDM, L-band and XL-band of 1518 – 1559 MHz. The return link (to the satellite) is TDMA, L-band 1626.5 – 1660.5 MHz. and XL-band 1668.0 – 1675.0 MHz . The channel plan is controlled by the network which tells the terminal which channel to use. Channels are up to 200 kHz wide and each 200 kHz sub-band can be assigned to one terminal or shared between multiple terminals. The system includes closed loop power control, and the terminal also includes power control to maintain Tx power within ± 1dB. The Tx power EIRP is 15.1dBW Page 5 of 13
