Fast Deployment • Dynamic spectrum coordination that minimizes the time to define rules of coexistence; User Experience • Operators can enhance the user experience through carrier aggregation to LTE New Business Models • Neutral host solution for third party operations in venues, airports, etc .; • It makes possible the secondary market of spectrum use; Usage Efficiency • It allows the use of spectrum (scarce resource) in a region where there is low use or low impact to the operation of another systems; • Use of sub-bands of regional use not tendered; It is the simultaneous use of sub-bands of radio frequencies defined in a specific geographical area by a number of independent entities. Simply, it is the "cooperative use of common spectrum" by multiple users.

  16. 16. Transport Network FRONTHAUL HIGH TRANSMISSION CAPILLARITY The investment of optical fiber soars as cell site density grows. For instance, at 100 Cell Sites per square kilometer can be needed 20-50 km of optical fiber per square kilometer. New fronthaul interface must be used, such as: eCPRI and NGFI, in order for optimizing the network resources. SDN multi-domain controller will be needed for network slicing, but it will necessary for transport resource management optimization, reserving and dynamically configuring the proper resource for accomplishing the overall 5G service requirements. HIGH FIBER OPTICAL DENSITY REQUIREMENTS BBU CPRI OBSAI ETSI ORI Data Control Sync RRU/ RRH BBU N BBU 2 BBU 1 CRAN CoMP and e-ICIC can increase system capacity in 30 times distributed network; and they are feasible using C-RAN. However C-RAN needs fronthaul to connect RF modules. Based on ITU Technical Report GSTR-TN5G, fronthaul needs as throughput: 𝐵𝐶𝑃𝑅𝐼 = 𝐴 ∙ 𝑓𝑠∙ 𝑏𝑠 ∙ 2 ∙ (16⁄15), where: A is the number of antennas per sector; 𝑓𝑠 represents the sample rate (15.36 MS/s per 10 MHz radio bandwidth) and 𝑏𝑠 the number of bits per sample (15 for LTE). For massive MIMO and higher bandwidth, such as mmWave, the fronthaul requirements will explode. Also, mmWave has a benefit to provide a very high capacity but a short range coverage. Thus, multiplying the number of Smallcells . These Smallcells will be controlled in the cloud (Cloud RAN) and will need fiber optics for connectivity; Combination of huge number of Smallcells with fiber premises for connectivity will bring an important concern for 5G infrastructure. Higher order transport capacity (fiber) X Higher number of cellsites will impose a huge challenge to network operators for accomplish the 5G requirements; Some nations have created programs for helping countrywide fiber deployment. 0 km(fiber)/km2 10 km(fiber)/km2 20 km(fiber)/km2 30 km(fiber)/km2 40 km(fiber)/km2 50 km(fiber)/km2 60 km(fiber)/km2 10CS/km2 20CS/km2 30CS/km2 40CS/km2 50CS/km2 60CS/km2 70CS/km2 80CS/km2 90CS/km2 100CS/km2 2,5 Gbps 80,0 Gbps 3200,0 Gbps 12800,0 Gbps LTE (MIMO 2x2, 20 MHz) 5G (MIMO 8x8, 200 MHz) 5G (MIMO 8x8, 1 GHz) 5G (MIMO 16x16, 1 GHz)

  20. 20. Summary ● Innovation Platform: The 5G is strategic technology for several nations around world and its deployments will positively affect virtually all sectors of the industry, generating 12.3 trillion dollars on a global scale in next decade - according to IHS Markit 2017. Adoption, integration in many industry sectors will strengthen 5G's role in transforming technology in a GPT (Generic Purpose Technology). ● Tactile Internet: 5G will open a new set of internet services beyond audiovisual experiences with full interactive immersion. The latency will become more important than throughput in telecom services. ● Resource Management: The planned services for 5G will have new requirements that are difficult for existing networks to offer: peak rates greater than 10x; average rates 100x higher; 10x lower latency; number of connections 100x higher among other aspects. The proper resource management is one the key concern for providing successful 5G experience in conjunction with affordable services; ● Spectrum & Spectral Efficiency: Different use cases (eMBB, URLLC, mMTC) require different network resources and technologies. Thus, different spectrum ranges matches specific requirements since: massive connected devices, mission-critical services and higher ● Network Densification: The expected traffic density for 5G broadband services will surpass 1 Tbps/km2. This demand can only be attended by using a combination of higher spectrum bandwidth (such as mmWave) and network densification. Both mmWave and Network Densification will drive SmallCells deployments, playing important role for enhance network capacity bringing affordable solution for demands of 800 Mbps/km2 and above; ● Fiber Optics. Combination of huge number of Smallcells with fiber premises for connectivity will bring an important concern for 5G infrastructure. Fiber is main requirement for 5G Cell Sites (Macro and Small). Oi, as fixed incumbent operator in 26 Brazilian states, with over 370,000 km of fiber, has distinguish position in 5G infrastructure for serving to own mobile network service, but all remainder Brazilian mobile operators. ● Artificial Intelligence: A single 5G node has more than 2000 parameters and the complexity increases 50x from 4G to 5G. In Network Densification the number of cell sites will be 10 to 100 times 4G deployments, requiring a lot efforts for network configuration and optimization. Sophisticated algorithms to guarantee a proper operation will be required. ● Public Policy: On 2018, FCC has published “FCC’s 5G FAST Plan” breaking some barriers for SmallCells deployments, since tax exemption or minimize the impact of licensing. In Brazil, since 5 years ago Brazillian government has been done an important steps in order to create a right environment for SmallCells deployments, such as: femtocells regulation, tax exemption for smallcells and making use of the smallcells deployments more flexible in Antennas’ Law.
