WHY INTEGRATED ACCESS STRATEGY
Od TDM technológií k All IP, od hlasových služieb k internetu a televízii Stanislav Dzúrik 9
• Digital Agenda for Europe 2020
100 Mbps or more for 50% of HHs, 30 Mbps or more for all HHs
• Cost reduction (provisioning & fault clearance, buildings, energy, overhead)
• Necessity to enable to provide high speed BB services capable to compete in BB services according
to customers' needs in term of speed & quality & geographical footprint, constantly growing data demand
• Shortcomings of metallic access network concerning BB services:
•Insufficient quality for new/intended high speed services
•High quantity of faults, complicated topology & fault elimination
•Limited cable utilization due to physical limitations (e.g. interferences)
• True Fix/Mobile synergy effect thanks to optical network deployment (F2BTS) and Hybrid CPE usage
HIGHER BANDWIDTH DRIVES SALE AND CUSTOMER DEMAND
Od TDM technológií k All IP, od hlasových služieb k internetu a televízii Stanislav Dzúrik
Source: FCC, US market expectations, 2011
Customers are not interested in lower speed BB products when offered
higher speeds by the competition:
• 30 Mbps in 2020 will be just minimum BB (as 5 Mbps today)
• Average BB for 50% and more HH should be over 100Mbps
• Premium B2C customers >200Mbps, in cities 1Gbps
• For average B2B in 2020 we can already expect 1Gbps
• Lower BB access below 100Mbps will be BEHIND a hype significantly decreasing
after 2020
Smart Home, Video and OTT services will drive
demand:
• Video services rules (over 60-80% traffic)
• Ultra HD(4k TV), Multi-screen services (see HH
average)
• Connected devices (millions)
• Applications in the Clouds
• Social and OTT communications 0

ACCESS TECHNOLOGY EVOLVING IN MOBILE AND FIXED
Od TDM technológií k All IP, od hlasových služieb k internetu a televízii Stanislav Dzúrik
§ Implement FTTC/B (VDSL)/FTTH (GPON) technology
§ Optical deployment is used also for mobile sites
backhauling and hybrid access
§ To be able deliver 1Gbps customer access is requiring to
implement FTTH (GPON) technology
§ Modernize network to flexible bandwidth developing a
DWDM infrastructure (upgrade DWDM to 100G)
§ Capacity extension and boost by new RAN and LTE-A
§ With LTE and LTE Advanced requests capacity boost
-> backhauling over fiber
§ Mobile traffic growth depend on deployment of small
cells (smaller cells need fiber connection)
§ Fiber for wireless backhaul and mobile offloading

Deploy fiber to the most economical Point 1
Od TDM technológií k All IP, od hlasových služieb k internetu a televízii Stanislav Dzúrik
Exploding Bandwidth ! Universal Broadband Service ! I am convinced I need to bring fiber closer to my customers but … What is the best approach? ü Fibre-To-The-Home directly? ü Fibre-To-The-Node with re-use of existing copper pairs for the last km? ü Fibre-To-The-Building with re-use of existing in-building cabling? ü Fibre-To-The-Distribution Point with copper or small cells for the last drop? ü GPON? Vectoring? G.Fast? … ü Or… combining all of these?
Economical considerations rule the decision process !!!

FTTx COST COMPARISON, CAPEX + INSTALLATION
INVESTMENT • From FTTCab (4x) to FTTH (15x) • The closer to the subscriber, the
closer the cost to FTTH

TIME TO MARKET • Deploying FTTH is time consuming • Re-using existing copper can speed up
deployment
2
BANDWIDTH • FTTH: 1G and more • FTTx: 100M (VDSL2 Vectoring

• Transparent to applications/users: Two GRE tunnels are bonded to one logical IP channel
• Bonding Group makes buffering and re-ordering for packets in uplink direction
• CPE makes buffering and re-ordering for packets in downlink direction
• Robust networking experience: load sharing & automatic switchover in case of one link failure
• Policy server sets rules which streams would run in by-pass mode

TECHNOLOGY 1: FTTH GPON
Pros
FTTH solution, passive optic infrastructure
Cons Suitability
• 1G+++ speed per customer
•No need for parallel metallic infrastructure
• No power required – only passive
components are used
• One optical fiber per 64 customers
•Low number of active node locations (OLT).
• To reach the target (Cu-to-optical
migration), the whole area has to be
migrated
• Due to splitting ratio, available access range
20km only (for splitting ratio 1:64)
• Fiber termination (installation) at customer
premises needed incl. in-house cabling
• Localities with no metallic AN (new
localities, building after reconstruction, etc.)
• Localities with poor quality and/or
undersized metallic AN

Pros
FTTB solution, metallic+optic infrastructure
Cons Suitability
• No new in-house cabling installation needed
• Vectoring possible (VDSL2+, G.Fast)
• Use of self installation packet possible
• Due to splitting ratio, available access range
40km
• Mainly for block of flats (i.e. towns with
more than 20ths. inhibitans )
