Operator’s concern – Strategies to Follow
Fixed Operators
Threat
•Only Wholesale
Provider of
Broadband
services
Strategies
•Go wholesale
•Go mobile again (UMA)
•Invest in fixed broadband
•IPTV services
Mobile Operators
Threat
•Mobile VoIP and
fixed VoIP
•Single flat fee for
Mobile data
Strategies
•Fixed-Mobile Substitution
•Bandwidth pricing
•Content via mobile portals
Threat
•Combined fixed and
mobile threats plus
high discounts for
commercial bundles
Strategies
•Fixed-Mobile Convergence
•Content ownership
•Unicast and broadcast
•Home Gateways

Incumbent’s position
Situation
 We are Increasingly Wireless
 We are Increasingly Faster
 We are Increasingly Cheaper
 Price erosion is significant, and has quickly spread to next generation
services such as broadband and 3G voice.
 Convergence comes in many flavours - Fixed/Mobile, Telecom/IT,
Telecom/Media, Terminals, Services, Applictions..
 Competition Increases
Answer?
 Making strategic decisions (invest on new technologies – integrate
daughter companies to mother one – provide motives to old personnel for
the sake of new personnel)
 Fixed and Mobile speeds are increasing at accelerating speeds

What is UMA - GAN?
UMA  one terminal (mobile – wireless - fixed) for all services
WiFi
IP net
Handover
GSM or
UMTS
Mobile
Operator
 How is achieved?
User moves in and out of WLAN proximity without loss of call
Seamless call Handover once you move from WiFi to GSM and vice
versa
UMA extends the GSM coverage in indoor environments (Houses, hot
spots and SOHOs) through the use of WiFi access points

Fixed operators integrate
wireless and fixed to prevent
erosion
Selling points: one device, one
number, one bill, one
messaging platform
But primary value is reduced
tariffs for fixed vs. mobile (via
VoIP or PSTN) and
convenience of single handset
If mobile voice pricing
continues to fall (permitted by
3G spectral efficiency), what's
the incentive to still used fixed
for voice?
Result: Consumers will more
rapidly migrate to mobile only
than to converged fixed/mobile

Femtocells
Femtocells are small cellular base stations similar to
(GSM/UMTS) stations which have been designed for use
in indoor environments.
Subject: Broadband Wireless Technologies for the Delivery of Converged Services

Femtocells key points
•
Access point GSM/3G in indoor environment coverage ≈
50m
•
Allow the same terminal to be used indoors and
outdoors
•
Low power consumption (10μW-25mW)
•
Seamless handover from macro cells to femtocell

Benefits of Femtocells
Benefits to the consumer
•
•
•
•
•
Continue using the existing mobile
device (one number, one
phonebook)
One mobile number of one mobile
and one fixed per user (with femto
zone tariff)
Better indoor coverage
Seamless operation indoor and
outdoor
One consolidated bill for voice
(fixed, mobile and broadband
services)
Benefits to the operator
•
•
•
•
•
•
Provides mobile coverage
where is needed the most
Increase network capacity
Improved customer loyalty and
reduced churn
No requirement for dual-mode
handset
Response to the VoIP threat
Even if the indoor voice
services are offered for “free”
due to competition the mobile
operator can still benefit from
the terminating fees.

Broadband Fixed Mobile (BFMs)

Terminals with dual radio (WiFi/GSM or 3G)

Access in indoors thru WiFi and access thru GSM in outdoors

Terminals from Nokia – QTEK - Ericsson
