- 2G: Second Generation. Wireless networks based on digital technology. 2G systems offer increased voice quality and capacity over 1G systems. Historically, 2G systems provided voice and 9.6 to 14.4 kbps circuit-switched data service.
- 2.5G: Refers to technology that is more advanced than 2G, but which does not meet the requirements for 3G. 2.5G technology is added to a 2G network to provide packet-data service and data rates that range from 20 to 40 Kbps, 2.5G is soften anonymous with GPRS networks.
- 3G: Third Generation. Wireless networks designed to increase voice capacity and provide high-speed data over 2G and 2.5G networks. According to the official ITU definition, a 3G network must provide a minimum of 144 Kbps.
- 4G: Fourth Generation. Wireless networks designed to increase faster data rates than 3G technologies. Voice service is provided using a special form of VoIP.
- Average revenue per unit (ARPU): This acronym refers to the average monthly revenue produced per subscriber.
- Base Station: Often referred to as a cell site, a base station is a transmitter/receiver location, through which radio links are established between the wireless system and the wireless device. The cell site is comprised of an antenna tower, transmission radios and radio controllers. Each cell in a cellular network requires a base station.
- BRIC: This acronym refers to the countries Brazil, Russia, India, and China which collectively represent nations with strong economic growth.
- CDG: This acronym refers to the CDMA Development Group. Founded in December 1993, CDG is an international consortium of companies who have joined together to lead the adoption and evolution of 3G CDMA wireless systems around the world. The CDG is comprised of CDMA service providers and manufacturers, application developers and content providers. To lead the rapid evolution and deployment of 3G CDMA-based systems, based on open standards and encompassing all core architectures, to meet the needs of markets around the world.

- CDMA: Code-Division Multiple Access CDMA is a digital wireless technology that works by converting speech into digital information, which is then transmitted as a radio signal over a wireless network. Using a unique code to distinguish each call, CDMA uses spectrum efficiently, enabling more people to share the airwaves simultaneously without static, cross-talk, or interference.
- CDMA2000: A direct evolution from cdmaOne technology. CDMA2000 provides a set of specifications which offer enhanced voice and data capacity. The CDMA2000 family includes CDMA2000 1X, CDMA2000 1xEV-DO Rel. 0 and Rev. A currently.
- GSM: A 2G wireless telecommunications standard for digital cellular services deployed first in Europe. GSM is based on TDMA technology and provides circuit-switched data connections at 9.6 kbps.
- IP: Internet Protocol. IP is the most important of the protocols on which the Internet was based and is part of the TCP/IP protocol.
- Location based services (LBS): These services are defined as applications that incorporate GPS and other network-based location-determining technology. Subscription Types:
- Navigation/Mapping/Directions
- Fleet Management
- Field Service Automation
- Sales Force Management
- OMH: Open Market Handset. This initiative is a strategic effort to benefit the CDMA ecosystem by enabling open distribution of handsets across networks and regions by expanding R-UIM SIM capabilities to support a full set of competitive features and standardizing a uniform device and network implementation for each feature.
- MMS: Multimedia messaging service. MMS allows wireless device users to send multimedia, such as video or digital photos, from one device to another.
- PMS: Pantone Matching System; allows designers to "color
match" specific colors when a design enters production stage
- MWG: Marketing Work Group; The OMH MWG is a working
group under the OMH SIG that is tasked with marketing
communications (messaging, web site, logo, etc .) to promote
and to support the OMH initiative
- R-UIM: removable user identity module; see SIM
- SIG: Special Interest Group
- SIM: subscriber identity module; see R-UIM
- SMS: Short messaging service. SMS is a store-and-forward message service available on many 2G and all 3G wireless networks. It allows users to send and receive short text messages usually 160 characters or less to and from wireless handsets.
- TAG: Test requirements and Acceptance Group; The OMH Test requirements and Acceptance Group (TAG) is a technical working group under the OMH SIG . This group is tasked with the following responsibilities on behalf of the OMH ecosystem:
- Manage OMH test requirements
- Provide an industry forum for discussing OMH test requirements and acceptance
- Accept devices and networks into the OMH ecosystem and authorize use of the OMH Logo
- Maintain an ecosystem web site that lists all accepted OMH devices and networks
