Definition: HSPA (High Speed Packet Access) is a term used to describe certain 3G cellular network protocols. HSPA utilizes the HSDPA protocol that supports theoretical maximum data rates between 1.8 Mbps and 14.4 Mbps.

An enhanced version of HSPA called HSPA+ or Evolved HSPA has also been deployed by some carriers targeting the mobile broadband market. HSPA+ is the fastest 3G protocol, supporting data rates up to 84 Mbps for downloads and 22 Mbps for uploads.

As with all cellular protocols, the actual data rates a person can achieve on their phone with either HSPA or HSPA+ is much lower than the rated maximum. Typical HSPA speeds are 1 Mbps or lower and 5 Mbps or lower with HSPA+.
