HSPA

 HSPA (High Speed Packet Access) is a set of wireless network technologies that provide high-speed data transfer rates over cellular networks. It is an enhancement to the earlier 3G (third-generation) cellular network standards, such as UMTS (Universal Mobile Telecommunications System) and CDMA2000.

HSPA uses a combination of two technologies: HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access). HSDPA improves the data transfer rate on the downlink, which is the connection from the network to the device, while HSUPA improves the data transfer rate on the uplink, which is the connection from the device to the network.

HSPA can provide data transfer rates of up to 42 Mbps (megabits per second) on the downlink and up to 11 Mbps on the uplink, depending on the network configuration and the capabilities of the device. It has been widely adopted by mobile network operators around the world as a way to offer faster data transfer rates over their 3G networks, before the deployment of 4G LTE.
