At this week’s CTIA Wireless 2005 conference in New Orleans, Nokia is showing an Internet High Speed Packet Access (I-HSPA) solution based on existing WCDMA.
Nokia I-HSPA is a 3GPP standards based simplified network architecture innovation from Nokia, implemented by adding I-HSPA functionality to an existing Nokia WCDMA base station. The basic performance of Nokia I-HSPA will resemble that of the traditional High Speed Packet Access (HSPA) solutions, namely High Speed Downlink & Uplink Packet Access. Nokia said the downlink bit rate can reach 14.4 Mbps and the uplink 5.8 Mbps. Nokia I-HSPA is based on a standard HSPA radio interface.
Also at CTIA Wireless, Nokia is demonstrating HSUPA (High Speed Uplink Packet Access), a UMTS/WCDMA uplink evolution technology currently being standardized in 3GPP. HSUPA, which enhances the uplink speed of UMTS/WCDMA networks, is the next step after HSDPA. HSUPA will enhance advanced person-to-person data applications with higher and symmetric data rates, like mobile e-mail and real-time person-to-person gaming. The Nokia HSUPA solution will initially boost the UMTS/WCDMA uplink up to 1.4 Mbps and in later releases up to 5.8 Mbps.
