2 Micrwave technlgy Transmitting infrmatin Micrwave transmissin is the transmissin f infrmatin r energy by micrwave radi waves *Wikipedia Micrwave technlgy has been used widely t supprt backhaul mbile netwrk prviding the required capacity, latency and reliability fr the 4.x netwrks 2 Nkia Netwrks 2015

3 Mbile backhaul netwrk Types, frequencies and channel spacing Three types f backhaul netwrks 1. Smart cells 2. Lng-haul 3. Shrt-haul *Type vs Frequency vs Channel Spacing 3 Nkia Netwrks 2015

4 Micrwave transprt netwrk Challenges twards 5G era 5G requires fast bradband, massive machine-t-machine cmmunicatins and critical machine cmmunicatin Stringent demands n the transprt netwrk s capacity, reliability, energy efficiency and latency NFV and SDN drive als changes Anther factr is the new Radi Access Netwrk (RAN) architectures, adding centralized RAN and clud RAN t the well-knwn distributed RAN and intrducing new frnthaul interfaces Distributed RAN Centralized RAN Clud RAN 4 Nkia Netwrks 2015

5 Increased demands n transprt Enabling netwrk slicing Different kind f services require a mre dynamic transprt netwrk mbile bradband will require huge capacity and vide caching capabilities massive IT will need high density but withut mbility missin-critical applicatins will be mre abut lw latency and high reliability 5G netwrk is sliced int parallel and independent lgical end-t-end netwrks each slice is dedicated t a specific set f requirements efficient deliver f simultaneus services 5 Nkia Netwrks 2015

6 Building high-capacity respnsive micrwave transprt Spectrum Cnsideratins Critical asset fr micrwave transprt. Frequency bands used fr wireless transprt range tday frm 4 t 86 GHz. Traditinal micrwave frequencies range frm 4 t 42 GHz and millimeter-wave frequencies are cnsidered abve 42 GHz Tday, nly V-band (60 GHz) and E-band (70-80 GHz) are used fr millimeter-wave wireless backhaul. Higher frequency bands such as the W-band (90 GHz) and D-band ( GHz) are being studied fr future standardizatin A micrwave channel is als characterized by its channel size. The higher the frequency, the wider the channels ptins: frm 3.5 MHz t 112 MHz fr traditinal frequencies, frm 250 MHz t 2 GHz fr millimeter-wave frequencies 6 Nkia Netwrks 2015

7 Smart spectrum usage Useful techniques There are several techniques t increase capacity f a given radi channel: 7 Nkia Netwrks 2015

8 Carrier aggregatin A pwerful technlgy Ability t cmbine tw r mre physical radi channels, perating in the same r different bands, int a single lgical channel A smart way t explit the specific characteristics and advantages f different frequency bands t supprt different services with different requirements in ne lgical channel by grming several physical channels with different characteristics * Pssible cmbinatins and benefits 8 Nkia Netwrks 2015

9 Carrier aggregatin Cmbining traditinal and new bands Cmbinatin f a traditinal frequency band with a millimeter-wave band t address evlving capacity needs Standard micrwave band prvides the reliability while the millimeterwave addresses the capacity need, thanks t larger channel sizes. In additin, the millimeter-wave ensures lw latency due t wider channels 9 Nkia Netwrks 2015

10 Carrier aggregatin Implementatin f dynamic end-t-end netwrk slicing Three services with three different requirements as an example 10 Nkia Netwrks 2015

11 Carrier SDN Bringing prgrammability and respnsiveness SDN will enable the rapid creatin, ptimizatin and terminatin f services Micrwave transprt netwrks will have t becme mre flexible and respnsive. Carrier SDN is the best ptin t ptimize micrwave transprt resurces acrss the netwrk 11 Nkia Netwrks 2015

12 Nkia Wavence The micrwave slutin fr 5G transprt Wavence slutin intrduces innvative, high-capacity ultra-bradband transceivers t supprt peratrs as they transitin t 4.5G, 4.9G and eventually 5G netwrks Ultra-bradband transceiver (UBT) twin, and the UBT 80, a cmpact E- band radi, supprt carrier aggregatin t deliver multi-gigabit, lw latency micrwave transprt. Explitatin traditinal micrwave frequency ranges (up t 42 GHz), as well as millimeter-wave frequencies (up t 86 GHz) utilizing the full range f frequency bands used fr wireless transprt tday High utput pwer, advanced mdulatin schemes and carrier aggregatin are sme f the supprted technlgies f the dual carrier (Twin) and E-band radi (80) UBTs ready t prvide high-capacity, lw-cst and ultra-respnsive cnnectivity Nkia SDN carrier slutin is supprted t prvide prgrammability fr telc clud and 5G netwrk slicing 12 Nkia Netwrks 2015
