Nokia Cooks Up I-HSPA

摘要

When it comes to 3G air inter-faces, everyone in the indus- try knows there's more to 3G than meets the eye. Every major technology has its own subsets, variants and extensions. By the time you get to know one, another is invented. Most people in the wireless industry also are well-acquainted with W-CDMA (aka UMTS or 3GSM), and most know the air interface is evolving with higher data rates brought about by highspeed downlink packet access (HSDPA) and its uplink equivalent, HSUPA. Those two upgrades for W-CDMA will dramatically boost wireless data rates, going from today's 384 kbps for W-CDMA to as fast as 14 Mbps for HSDPA (although less than 2 Mbps initially). Major W-CDMA vendors all are building HSDPA/HSUPA solutions.
