In 2011, global mobile

data traffic more than

doubled (2.3X growth) for

the fourth year in a row,

despite economic

uncertainty, continued

traffic offload, and the

broader adoption of

tiered pricing.




By 2016, 60 percent of mobile users (3 billion people) will belong to the Gigabyte Club, generating more than one gigabyte of mobile data traffic per month. In 2011, 0.5 percent of mobile users belonged to the Gigabyte Club.

• Scope & Assumption

• Compare network cost per GigaByte ($/GB) across:

Femto

SP Wi-Fi

Macro Radio network

• For different User types:

Bronze (300MB/month user)

Silver (1.5GB/month user)

Gold (5GB/month user)

• Indoor Scenario

Cisco & ABIresearch Model


• Pre Smartphone Age Busy Hours : Morning & early Evenings

Traffic Type : Voice & Messaging

• Post Smartphone Age Busy Hours : mid to late Evenings

Traffic Type : mobile Data & Video

• Results It is easier to compare network cost between Macro & Micro coverage

Every data byte offloaded via Wi-Fi or Femto will reduce Carrier RAN cost

• Busy Hour Ratio = 7%

Shifting User Behaviour


• Bronze 300 MB/Month • Little advantage to use macrocells

• Limited benefit on WiFi

• Silver 1,5 GB/month

• Tipping point for macro/WiFi, analysis on cost reccomended

• Gold 5 GB/month

• Cost advantage even if femto/WiFI is fully subsidized.

• Even better business case with amortization.

1. Optimization – increases network

capacity and reduce 3G/4G data traffic

overload by offloading traffic with SP

Wi-Fi.

2. Monetization – creates new revenue

streams by taking advantage of

advanced technology that provides

secure delivery of location-based

services to mobile devices

3. Churn Reduction – expand a physical

footprint with a cost-effective Wi-Fi

solution to keep customers on the

service provider network as they move

from home to the train to the office.
