Mobile data growth

LTEHSPA

Nokia sees Mobile Broadband traffic grow ~90% per annum

• Combined data volume for over 100 Nokia HSPA and LTE customers

• Data growth 3.6x during 2 year period corresponding to 90% annual growth

• 2x per annum makes 1000x over 10 years (210 = 1024)

• 1000x traffic can be supported by • 10x efficiency • 10x sites • 10x spectrum

• Unique combination of licensed + unlicensed bands • Licensed band provides reliable connection and quality of

service for mobility, signaling, voice and data • Unlicensed band boosts data rates – ”Opportunistic use” • LTE-U to be integrated into small cells beside Wi-Fi • Downlink:uplink asymmetry up to 10:1 in LTE networks • Targets public hotspots managed by operators

LAA allows to tap into unlicensed spectrum resources within the 3GPP MNO model

Licensed Shared Access to spectrum

• LSA allows for dynamic sharing while meeting the requirements of mobile operators and incumbents for predictable conditions of spectrum use and hence predictable QoS.

• LSA opens bands otherwise locked for long time for harmonized MBB use like the 2.3 GHz band in Europe supported in commercial devices today.

• LSA is a simple concept which can be implemented today with evolution path towards full dynamic use cases like spectrum pooling and the US SAS model.

• The Finland trial has proven above aspects testified by all stakeholders including regulator, incumbent, mobile operator and supplying industry. Visit http://core.willab.fi/ for more information on the trials
