Operator’s concern – Strategies to Follow
Subject: Broadband Wireless Technologies for the Delivery of Converged Services [email protected]
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
How is achieved?User moves in and out of WLAN proximity without loss of callSeamless call Handover once you move from WiFi to GSM and vice
versaUMA extends the GSM coverage in indoor environments (Houses, hot
spots and SOHOs) through the use of WiFi access points

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

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 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.
