1.4.4 Data

The wireless modem supports the following data protocols:

• GPRS (General Packet Radio Service)

The wireless modem is a Class B terminal. The wireless modem is GPRS multi-slot class10 (4+2) enabled, capable of receiving at a maximum of four timeslots per frame (down link), and transmitting in two timeslots per frame (up link). See section 1.4.5 for multi-slot allocation by class.

• CSD (Circuit Switched Data)

The GR64 wireless modem is capable of establishing a CSD communication at 9.6 kbps over the air.

1.4.5 GPRS Multi-Slot Support

GSM Multi-slot classes supported by Gx64 devices

Multislot	Maximum slot allocation					Allowable
							Max data rate
Class	Downlink		Uplink		Active	Configuration
8	4	1		5		1 up; 4 down	8-12Kbps Send
							32-48Kbps Receive
						1 up; 4 down	8-12Kbps Send
							32-48Kbps Receive
10	4	2		5
							16-24Kbps Send

2 up; 3 down

24-36Kbps Receive

1.4.6 SIM Card

The GTR64 supports an external SIM card through the integrated SIM holder. Both 3V and 1.8V SIM technology is supported. Older, 5V SIM technology is not supported.

1.4.7 Power Consumption

Feature		Sleep Mode	Idle Mode	Transmit
		DRX 8		Operation
GSM850 & E-GSM900	Voice/CSD	1.6 mA	17 mA	2000 mA
	Data (GPRS)
GSM1800 & GSM1900	Voice/CSD	1.6 mA	16 mA	1450 mA
	Data (GPRS)

The power consumption figures shown represent typical average current for maximum transmitted power, single uplink (transmit) slot, and single downlink (receive) slot. The module will consume more average power in different multi-slot configurations, the worst case being that of two uplink and three downlink slots.

1.5 Precautions

The GTR64 as a standalone item is designed for indoor use only. To use outdoors it must be integrated into a weatherproof enclosure. Do not exceed the environmental and electrical limits as specified in “Technical Data”, page 32.
