RIM And Alpha Micro Sign Supply Agreement To Deliver OEM Radio Modems For GSM/GPRS Wireless Networks

RIM Receives International Regulatory Certifications For Radio Modems Operating at 850/1900 MHz And 900/1800 MHz Frequencies

Waterloo, ON and Basingstoke, UK - Research In Motion Limited (RIM) (Nasdaq: RIMM; TSX: RIM) and Alpha Micro Components today announced a new supply agreement that enables Alpha Micro to distribute RIM's OEM radio modems for GSM/GPRS wireless networks to device manufacturers in the UK and Ireland. RIM also announced today that its radio modems for GSM/GPRS networks received regulatory certifications in North America, Europe and Asia Pacific.

RIM's radio modems are designed to allow Original Equipment Manufacturers (OEMs) to wirelessly enable applications such as telemetry, telematics, mobile computing and financial transactions. For example, manufacturers use RIM's OEM radio modems to wirelessly enable ruggedized laptop computers and provide field service personnel with remote access to corporate information systems. This wireless connectivity enables field service personnel to increase both productivity and customer service.

Alpha Micro offers distribution expertise, custom integration and design services, enabling device manufacturers to achieve a competitive advantage through decreased time-to-market for wireless-enabled products.

Trintech Payment Solutions To Be Wirelessly Enabled With RIM Radio Modems

Trintech, a leading point-of-sale terminal manufacturer, will use RIM's radio modems integrated with Alpha Micro socket boards to wirelessly enable its new Compact GPRS Point Of Sale (POS) terminal. Trintech's product is targeted to operators of prepaid network services that are deploying new terminals and to companies that are managing terminals for credit and debit card transactions.

"Trintech is dedicated to providing simple and secure wireless payment solutions," said John Harte, General Manager of Trintech's POS Division at Trintech Group PLC. "We chose to embed RIM OEM radio modems in our point-of-sale terminals because of their superior quality and design. Alpha Micro also provided us with the engineering services required to easily integrate RIM's wireless modems into our products."

RIM Receives Regulatory Certification For GSM/GPRS Radio Modems

RIM's OEM customers are provided with reliable, high-quality radio modems that offer efficient power management, proven radio code and easy integration. The new RIM GSM/GPRS radio modems have similar physical dimensions and electrical interfaces as RIM's RIM 902M (Mobitex) and RIM 802D (DataTAC) OEM radio modems, providing manufacturers with the versatility to easily deploy products for multiple wireless networks. The RIM 1802G and RIM 1902G radio modems are the first commercially available RIM modems that support all current GSM/GPRS frequencies (850/1900 MHz and 900/1800 MHz).

"RIM's radio modems are based on the same RIM hardware and software technologies embedded in BlackBerry® handhelds and offer high-quality, proven technologies to device manufacturers," said Christos Papakyriacou, Managing Director at Alpha Micro. "Our relationship with RIM demonstrates our commitment to offering our customers the best wireless components available."

"Together, RIM and Alpha Micro will provide device manufacturers with the embedded technologies and services needed to integrate radio modems efficiently and reliably," said Mike Lazaridis, President and Co-CEO at Research In Motion. "Our new GSM/GPRS radio modems follow our long-standing tradition of performance and leadership in this sector and have now been certified for use in North America, Europe and Asia Pacific."

RIM has received key regulatory certifications for the RIM 1902G and RIM 1802G radio modems for GSM/GPRS wireless networks. The Federal Communications Commission (FCC), Industry Canada (IC) and PCS Type Certification Review Board (PTCRB) issued approval for the RIM 1902G operating on the 850/1900 MHz frequencies in North America. The Radio and Telecommunications Terminal Equipment (R&TTE) and GSM Certification Forum (GCF) issued approval of the RIM 1802G radio modem for operating on 900/1800 MHz frequencies in Europe and Asia Pacific.

General Packet Radio Service (GPRS) is a global wireless standard that uses existing GSM (Global System for Mobile telecommunications) radio base stations and converts wireless data into standard Internet packets, enabling interoperability between the Internet and the GSM/GPRS network.
