e applications in markets, such as digital television broadcasting, defense and security, energy, and utilities. In 2012, the wireless transmission unit continued to focus its R&D efforts on: The 9500 Microwave Packet Radio, a next-generation multi-purpose packet microwave radio, which allows service providers to transform their networks from legacy, or time-division multiplexing, transport to packet transport. Packet transport supports the shift to IP-based services and data traffic and growth. IP-enabled microwave for mobile backhaul applications, which combines packet-based wireless transmission with IP networking to help service provider’s transition from 2G to 3G or 4G mobile networks. Wireless The company’s wireless products and services portfolio enables mobile network operators to satisfy the demand for mobile data capacity. In 2012, it focused its wireless investments in three areas – LTE (4G), small cells, and an update to its radio access network (RAN) products. In 2012, the company also announced lightRadio Wi-Fi, a product that enables service providers to extend high-speed mobile broadband services across both mobile and Wi-Fi networks. CDMA (Code Division Multiple Access) The company’s CDMA strategy is focused on maintaining its installed base of this technology by delivering quality, capacity and operations, administration and management improvements to its customers. Its multi-technology products accomplish this evolution. Introducing elements from the company’s lightRadio program into its CDMA product provides CDMA operators the benefits of the latest wireless advances and reinforces its commitment to eco-sustainability. CDMA technology supports circuit switched voice with the CDMA2000 1X standard and packet data with the 1x EV-DO Revision A standard. The company has developed improvements for both standards, such as 1X Advanced that uses improved interference cancelation routines to improve the voice capacity and quality of existing networks, and has the potential to triple the current voice capacity with new 1X Advanced handsets. GSM (Global System for Mobile Communications) The company develops mobile radio products for the 2G GSM standard, including GPRS/EDGE (or general packet radio service/enhanced data rates for GSM evolution) technology upgrades to that standard. W-CDMA (Wideband CDMA) W-CDMA or universal mobile telephone communications systems is the 3G wireless technology derived from the GSM standard deployed worldwide. High speed packet access (HSPA) and HSPA+ are evolutions of W-CDMA. The company has focused its investments on ensuring that its W-CDMA customers could provide an experience to various subscribers using smartphones and other broadband devices on their networks by managing the network signaling load. Its W-CDMA RAN portfolio includes multi-technology, multi-carrier components that allow for a technology evolution to LTE. LTE The company supplies LTE equipment. LTE offers service providers a compelling evolution path from various existing wireless networks (GSM, W-CDMA, and CDMA) to 4G wireless by simplifying the RAN and converging on a common IP base, leading to network performance and a lower cost per bit. The company’s LTE offering could be deployed on an aggressive schedule as a result of the tools and processes developed by its engineering and integration teams. As of December 31, 2012, it had entered into contracts to deploy commercial LTE networks with approximately 25 services providers, including Verizon Wireless, AT&T Corp., and Sprint, and had approximately 70 LTE trials covering different geographies, frequencies, and applications. The company supplies an LTE variant known as TD-LTE (Time Division LTE). TD-LTE would be used by mobile network operators who have unpaired spectrum, where data transmissions are sent and received through the same frequency. The company is engaged in TD-LTE deployments and trials worldwide. Small Cells The company has a portfolio of small cells in different forms, capacities, and power levels that could be used in homes, enterprises, public venues, or other metropolitan locations. In 2012, the
