The challenges of WiMAX service activation

On cellular networks, the operator retains primary control over the devices operating on its network, but WiMAX will change this.

In traditional cellular networks, the operator retains primary control over the devices operating on its network, with most devices being directly supplied to the subscriber through the operator's retail stores or partners, and pre-provisioned with the operator's software or SIM card.
WiMAX will change this. Subscribers buying a WiMAX-enabled device will be able to choose the device model they prefer and buy it from an operator-independent retailer. Separating the device distribution model from the service delivery model will result in a strong supply chain of devices needed for successful uptake of mobile applications.
This represents a new operating model for the WiMAX operator - one that reduces the pressure to subsidize devices, maintain extensive inventory, and sell non-core devices to subscribers.

A range of devices operating on the network can create complex challenges for customer support staff.
The ability to push firmware to the device enables users to keep their devices updated, reducing customer support workload and cost for the operator. Ideally, device management, including firmware updates and device configuration, should be tied to the plan preferences of each subscriber and to an automated identification of the device.

The ability to set different priority levels for subscribers becomes a requirement. Because WiMAX can support a range of applications such as VoIP, videoconferencing, or video on demand (VoD), the operator needs the ability to set QoS prioritization. Subscribers need to be able to change their profiles and seamlessly download the required configuration settings to their devices.
