mobile broadband (MBB)

Mobile Broadband (MBB) is about wireless Internet access for mobile devices. The data rates of Mobile Broadband for the uplink and downlink have changed rapidly with the development of the various mobile communications networks and depend on the current mobile communications generation. Mobile Broadband operates in the frequency spectrum between 225 MHz and 3.7 GHz.

While data rates of 9.6 kbit/s ( GSM ) and data rates of around 200 kbit/s were achieved in the 1990s with GSM and the GPRS and EDGE technologies based on it, data rates of 15 Mbit/s were already achieved with UMTS, a 3rd generation( 3G) mobile communications system. A further increase in data rates occurred with the 4th generation( 4G) mobile communications systems. These include HSPA+, Mobile WiMAX, Long Term Evolution( LTE) and LTE-A, as well as Mobile Broadband Wireless Access( MBWA). These technologies achieve data rates of between 20 Mbit/s and 1 Gbit/s, which are exceeded many times over with 5th generation( 5G) mobile communications systems. This mobile communications network also offers Enhanced Mobile Broadband( eMBB), a service category with extremely high data rates of up to 10 Gbit/s.

With these data rates, Mobile Broadband supports the transmission of streamingvoice and video, as well as the transfer of large amounts of data.
