HSUPA stands for High Speed ​​Uplink Packet Access. The download speeds increased rapidly, but the upload lagged behind, the upload at HSDPA is 125 KB/s. That is why the HSUPA standard has been designed, which is also an extension of 3G. In this standard, the maximum upload has been increased to 720 KB/s. 3G networks are still offered within the M2M service.
