With LTE connectivity, users could download a movie or a big file more than 4G in just few seconds via HUAWEI E589 , because E589 could reach up to 100Mbps downlink data speed and uplink speed up to 50mbps.
And the larger capacity of battery helps it to run much longer time than previous HUAWEI E5 models.
In additional, HUAWEI E589 Mobile WiFi is HSPA+ & HSDPA backward, which means E589 hotspot could auto switch to 3G HAPA network to search the fatest available network to support High speed surfing.

In real working networking environment, perhaps it can't reach the peak speed as we expected, but it's defenitely faster than usual.
