Gigabit/s is real
Ericsson - 900+ Mbps 60 MHz of aggregated bandwidth Ericsson's commercial base station RBS 6000
Nokia Siemens Networks - 1.4 Gbps 100 MHz of aggregated bandwidth NSN’s commercial Flexi Multiradio 10 Base Station
![Page 13: LTE-Advanced: The Path towards Gigabit/s in Wireless Mobile Communication](https://reader036.vdocuments.net/reader036/viewer/2022062410/56816376550346895dd45379/html5/thumbnails/13.jpg)
LTE-A – is not revolution, it is evolution
Users should not expect 1 Gbps speeds on their phones next year
Operators do not have 100 MHz of spectrum
No way to use 8 antennas in UE devices

Where to use
Cars or Trains DSL in rural areas with LTE-Advanced Improve efficiency wireless connections Decrease of costs
