WiMAX VoIP
A fixed wireless solution not only offers competitive internet access,
it can do the same for telephone service thus further bypassing the
telephone company's copper wire network. Voice over Internet Protocol
(VoIP) offers a wider range of voice services at reduced cost to
subscribers and service providers alike. The diagram below illustrates
a typical solution where a WiMAX service provider can obtain wholesale
VoIP services (no need for the WiMAX service provider to install and
operate a VoIP softswitch) at about $5/number/month and resell to
enterprise customers at $50.
Figure 34: VoIP is the "killer app" for WiMAX
In residential markets, VoIP is a "must offer" service. Without the additional revenue per user (think ARPU where "A" is for average), WiMAX does not offer a compelling reason to switch from other forms of residential broadband. When bundled with broadband internet access and IPTV, a WiMAX triple play becomes very attractive to residential subscribers. Given the QoS, security and reliability mechanisms built into WiMAX, sub-scribers will find WiMAX VoIP as good or better than voice services from the telephone company.
