WiMAX BenefitsWiMAX Benefits

Component makers

Creates a volume opportunity for silicon suppliers

Equipment makers

No longer need to develop every piece of the end-to-end solution

Can innovate more rapidly

Operators

Standards-based equipment means more cost-effective CPEs

Multiple equipment suppliers and lower costs = lower investment risk

Quickly provision E1+ level and “on demand” high-margin broadband

Scalable; remote management; supports differentiated service levels

Consumers

More choices for getting broadband access

Support for voice, data, video

GeographyGeography

Where will fixed and mobile systems deploy ? FWA:

Developed countries: Rural & suburban

Developing countries: Urban & suburban

Mobile: Urban & suburban

FWA and Mobile will co-exist In Urban (majority) and possibly Sub-urban areas

FrequenciesFrequencies

What frequencies will FWA & Mobile use? Typically different frequencies (similar to cellular evolution)

Current allocated frequencies (3.5GHz etc.) are granted for FWA only

Governments would typically charge additional licensing for mobile (especially after charging all existing mobile applications)

ETSI is working with regulators in order to grant a new frequency for mobile, especially due to the fact that the existing 3.5GHz frequency is already occupied in most places.

May reuse the already existing licensed band (depending on local allocation and usage)

FWA and Mobile will most likely operatein different frequencies

Deployment ScenariosDeployment Scenarios

What are the deployment scenarios of FWA & Mobile ?FWA deployments consists of smaller no. of medium sized cells (5-6km), which are maximal coverage driven

Mobile deployment consists of large no. of small cells (1-3km) which are capacity and continuous coverage driven

Mobile/portable devices typically have lower output power, which limits the possible cell range

FWA and Mobile will use different deployment scenarios

And What About 3G ?And What About 3G ?

3G has at least 2 years head start over the WiMAX mobility

Many mobile operators are already heavily invested in 3G (licenses & equipment wise)

SummarySummary

While Moving from FWA to Mobile … FWA and Mobile will operate

Using different frequencies

Using different coverage scenarios

Using different capacity planning scenarios

Using different protocols (at least at the beginning)

However will reuseThe FWA as backhauling for mobile cells
