Introduction

Introduction

The PTT Express solution is one of Zebra’s converged voice and data solutions which provide
communication solutions for many different types of enterprises and enterprise users.

PTT Express Solution Portfolio

PTT Express solutions include:

• PTT VoWLAN is a single mode solution designed to provide service to mobile users inside the

enterprise without regard to their location inside the facility or throughout a campus environment. The
solution provides mobile access over the enterprise Wireless Local Area Network (WLAN) to
comprehensive voice and data services. This includes services such as telephony, Push-To-Talk
(PTT), email, and text messaging that are typically tethered to the desk.

• PTT Express client creates Push-To-Talk communication capability between different types of devices

including PTT Smartphones, and mobile computers. Leveraging existing WLAN infrastructure, this
solution delivers simple communications across devices without the need for a voice communication
server.

• For most Zebra devices, a license is required to use PTT Express. For some value-tier devices, an

MDNA and PTT license is required. Refer to the License Manager User Guide for information on adding
a license to the device.

Devices Supported by PTT Express

Refer to the PTT Express User Guide for a list of supported devices.

The PTT Express client allows these devices to create Push-To-Talk communication capability between
different types of devices. Some of the devices listed may require a software download/install to add PTT
express to the device, but for many of the devices PTT Express comes pre-installed. The solution
leverages existing WLAN infrastructure and does not require a server.
