Hard Numbers and Experts' Insights on Migration to 4G Wireless Technology
As Wireless Network Speeds Increase, OFDM will Edge out CDMA
3G wireless networks are rolling out. Interest in streaming media and other high-speed wireless data applications are growing. To ensure wireless networks can meet future customer demand and remain competitive for years to come, operators and manufacturers are planning now for 4G wireless. Over the next few years OFDM radio technology will play a key role in this migration particularly in the wireless LAN, fixed broadband wireless, and mobile phone segments. These are a few of the conclusions in the new 46-page report, Hard Numbers and Experts Insights on Migration to 4G Wireless Technology now available from Alexander Resources, a leading research, consulting and education firm specializing in wireless communications.
Orthogonal Frequency Division Multiplexing sends data across multiple radio channels, each at a lower rate, combating interference effects that become unmanageable at very high data rates with systems such as CDMA. The advantages of OFDM and particularly MIMO-OFDM in a wide range of applications become more pronounced as the wireless industry moves to higher speeds, said Peter Rysavy, President of Rysavy Research and the reports author. But CDMA, whether CDMA2000 or WCDMA, still has a long way to evolve and it will be several years before vendors must switch to OFDM, he added.
