CONFIDENTIAL - SEE CONFIDENTIALITY RESTRICTIONS ON TITLE PAGE Page 2 of 14 1.0 Introduction This document includes a feature overview, product specifications, mechanical information, and basic user information for Enfora’s Enabler-G, an embedded OEM GPRS Class C modem. This low cost device is packaged in a small form-factor to facilitate a variety of embedded applications. It offers features and functions similar to Enfora’s Enabler-A and Spider-O CDPD modems. 2.0 General Description The Enabler-G is a self-contained General Packet Radio Service (GPRS) Class-C modem containing all functionality, to include RF and digital control, required to perform wireless data transfer over a GPRS network. Enabler-G has been designed to work as an embedded component in lap top PCs and other mobile platforms as well as handheld or portable host devices. 3.0 Safety and Regulatory Compliance This unit complies with specifications for a GPRS Class-C full-duplex modems with a maximum transmit output power of 0.6 Watts. This Enabler-G complies with US CFR 47, Part 24 Subpart E and Part 15 of the FCC Rules and Regulations and Canada RSS-188. Detailed Regulatory and safety statements are provided following Section 10.0 of this Manual. Basic safety precautions and guidelines for such devices must be observed, such as: • Do not expose the device to fire, open flames, or extreme thermal conditions. • Do not spill liquids on the device. • Do not disassemble or attempt to modify the device without he express written consent of Enfora. • Do not attempt to repair the device The Enabler-G complies with the FCC RF emission and hazard requirements when installed and operated within the constraints and limitations specified in this manual. Enfora is not liable for injury to personnel 4.0 GPRS Background General Packet Radio Services (GPRS) is a packet based wireless communication service that can deliver variable data rates as a function of assigned timeslots and maintain continuous connection to the Internet for mobile subscribers on Global System for Mobile (GSM) Network worldwide. Since GPRS is based on GSM communication, it can be single, dual or triple band depending on the area of the service, it will complement existing services such as circuit switched cellular phone connections and the Short Message Service (SMS). In general, GPRS packet-based service should cost users less than circuit-switched services, since their communication channels are being used on a shared-use, as-packets-are-needed basis rather than dedicated only to one user at a time. Once GPRS becomes available, mobile users of a virtual private network (VPN) will be able to access their private networks continuously rather than through a dial-up connection. GPRS will also complement Bluetooth, a standard for replacing wired connections between devices with wireless radio connections. In addition to the Internet Protocol (IP), GPRS supports X.25, a packet-based protocol that is used mainly in Europe and Asia Pacific. GPRS is an evolutionary step toward Enhanced Data GSM Environment (EDGE) and Universal Mobile Telephone Service (UMTS). CONFIDENTIAL - SEE CONFIDENTIALITY RESTRICTIONS ON TITLE PAGE Page 3 of 14 The key benefit with GPRS is the ability to sustain a permanent data connection allowing a free flow of information for the mobile user. The data through put in GPRS will be significantly higher due to the ability of GPRS mobile terminals to transmit and receive more information than standard GSM terminals. The GSM communication system, in general, is standardized to operate in multiple bands, primarily, the 900 MHz band which is assigned PGSM, EGSM, RGSM for short, 1800 MHz band which is assigned DCS and the 1900 MHz band which is assigned PCS. Both the GSM and DCS band are used globally for mobile voice communication. The PCS 1900 is used in North, Central and South America. • Enabler-G Model No. GSM0102 900/1800 MHz • Enabler-G Model No. GSM0103 900/1900 MHz Although the GSM digital voice standard has existed for well over a decade, it wasn’t until recently that the demand for wireless data capability has increased. GPRS is a protocol within the GSM standard which was developed to address the need for data only transmission. Although the GSM voice protocol does support data transmission, it is limited in data rate due to overhead within the voice protocol. What the GRPS allows is a faster data rate that is adaptive as well as being packet based. 5.0 Mechanical Characteristics Basic package dimensions and form factor information is provided in the following figures. 5.1 Connectors Control Connector The connector used to in…

Both the GSM and DCS band are used globally for mobile voice communication. The PCS 1900 is used in North, Central and South America. The GSM 900 band is disabled for these markets. Although the GSM digital voice standard has existed for well over a decade, it wasn’t until recently that the demand for wireless data capability has increased. GPRS is a protocol within the GSM standard, which was developed to address the need for data only transmission. Although the GSM voice protocol does support data transmission, it is limited in data rate due to overhead within the voice protocol. What the GRPS allows is a faster data rate that is adaptive as well as being packet based. The Enabler transceiver design is based on a proprietary chip set that complements size, cost and power consumption. Enabler-G919 is a dual band EGSM 900 MHz and PCS 1900 MHz design in a 1.7” x 2.7” x 0.2” housing. It communicates via an RF antenna port and a multiple pin digital connector. The RF and digital processors are design to operate at 3.8V. The band is selected at the front end via a high power RF Switch. This signal is then prefiltered to remove large out-of-band signals from compressing the LNA. It is then filtered again to prevent the down converter from converting unwanted signal into the IF band. An IF filter is used to set the channel BW to about 200 KHz. This high selectivity IF filter will allow the Enabler to operate through a high dynamic range. The AGC amplifier in conjunction with the DSP chip will automatically adjust the gain to maintain a constant baseband signal. The I&Q demodulator converts the RF signal into 2 baseband signals called Rx I & Q. This prefiltered I&Q signal is sent to the DSP processor w…
