The explosive growth of the Internet over the last decade has lead to an increasing demand for high-speed, ubiquitous Internet access. Wireless Internet access fills this growing need by offering Internet access out of the home and office. There are many wireless applications that satisfy vastly different needs for continuous, convenient, and flexible access to up-to-date information via the web.

Mobile cellular communication has evolved from the traditional analog system to today's third generation (3G)digital system. For high-speed data services, 3G+ standards have been developed which can achieve significantly higher peak data rates compared to W-CDMA and cdma2000. For example, high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA) technologies increase the downlink and uplink data rates of W-CDMA to 14.4 Mbps and 5.6 Mbps respectively. Standardization efforts are already underway to define next-generation cellular networks capable of supporting data rates up to 100 Mbps via the 3GPP long-term evolution (LTE) activities.

Figure 1 shows the mobility and data rate of different wireless applications.

Worldwide Interoperability for Microwave Access (WiMAX) is increasingly gaining popularity as a broadband wireless access technology with significant market potential. Based on the IEEE 802.16e-2005 standard, WiMAX supports mobile high-speed internet access within a metropolitan area network (MAN), and uses advanced signal processing schemes such as orthogonal frequency-division multiple access (OFDMA) and multiple input multiple output (MIMO) technology.

With advancements in semiconductor technology and signal processing techniques, wireless standards and systems are continually evolving. A hardware platform that can provide high processing bandwidth, flexibility, and a time-to-market advantage is needed to meet these demands. With a complete portfolio of high-performance as well as low-cost FPGAs and a risk-free migration path to low-cost structured ASIC technology, Altera® programmable logic devices (PLDs) deliver the processing bandwidth and flexibility required for wireless infrastructure designs. To accelerate the time-to-market, Altera also provides a wide array of intellectual property (IP), reference designs, and complete off-the-shelf partner solutions via the Altera wireless ecosystem.
