• APPS requires network resources, despite network will:
• Data consumption;
• Signaling consumption;
• And also require battery charges…..
•Main mobile operations system characteristics: Updates mechanisms, battery
consumption protection, hardware requirements, security issues.
•Understanding embedded technology like NFC.
•Validate SIM Card Application and integration possibilities
•RF and technologies combination: a large number of possibilities:
• Need of large scale of usage, in order to reduce cost/unit

TBR REQUIREMENTS:: MOBILE IS STRONGLY PUSHING OPERATORS
1. Flexibility in capacity upgrades;
2. Multi-standard and multi-frequency solutions
required (SDR), also for Small and Femto
solutions;
3. RF equipment has to support multi-carrier and
different standards simultaneously ;
4. LTE fully compliant with HETNET, taking
advantage also of non licensed spectrum (WiFi)
5. Reduced power consumption;
6. Full support of Self Organized Network (SON);
7. Full reuse of 2G/3G sites;
8. Support different backhaul strategies.
9. VoLTE complementing data offering.
10. RAN Sharing as an alternative….
Investments:
• Need to increase 3G capacity and build
good LTE coverage;
• Mobile world transforming to an IP world;
• Backhaul investments to cope with Mobile
Broadband capacity requirements.
Financials:
•Voice margins under pressure and inflation pressure;
•Data not expected to compensate in short term;
•Low EBITDA margins;
•High competitiveness in mobile market.
Regulation:
•Frequency auctions bound to new coverage;
•Competition Increase;
•Regulator now encouraging and facilitating sharing.

OUR ROADMAP:: OMINIPRESENT NETWORK
As data service coverage goes towards low density regions, it is imperative to take advantage of
a good mix of spectrum and technologies.

CONCLUSION&OUTLOOK
MOBILE BROADBAND will touch several requirements of building
a leading Mobile Data business.
HET-NET and SON will have prominent role of existing and
forthcoming network.
No more extensive coverage obligation: the challenge now is
improving quality and managing demand growth
RAN SHARING and spectrum sharing as a manner of levering a
“sustainable” 4G NETWORK.
