Different pros: Internet speed compared to Keenetic 4G increased by 1.5 times. Video quality has also improved significantly compared to Keenetic 4G, now it catches at least 1080p. After installing Keenetic Hero 4G, there was no need to use an external modem, the internal one can do its job well. Its cons: There is no frequency aggregation. Given the unstable incoming Internet signal between the external antenna and Keenetic Hero 4G, you will most likely have to install a router with frequency aggregation not lower than LTE category 12. Let's see what happens.
