e in particular managed services for wireline as well as mobile networks. These include experts in enterprise mobile devices, video conferencing, security, data centers, contact centers and wireless LANs (Wi-Fi networks). Many carriers that own mobile and landline networks recognize the potential of mobile services.

For example, one carrier developed an application that improves the efficiency of remote technicians by eliminating the requirement for a dispatcher to create a preset schedule that might be changed by longer or shorter than estimated repair jobs. Rather, when the technician informs the system of his availability, a message is sent to him with the details of his next appointment.
