Ease of sensitive and personal data access in the increasingly mobile world mean that most people in the wireless or telecommunications industries must understand how security applies to their technologies. New government and industry regulations also make security awareness mandatory in many roles across these industries. The purpose of this course is to provide students with a detailed understanding of security in wireless networks. In addition to understanding the specifics of the various wireless security standards, this course also explains how these standards work with other services and standards in real-world implementations to create a complete security infrastructure. This is a 8 hr. instructor led technical course intended to give the student a thorough understanding of both the theoretical and practical aspects of wireless security.  See the course details here.

 A Wireless Low Power and Lossy Networks (LLNs) is a network of embedded devices, such as sensors, that have limited power, memory, and processing capability. The growing importance of wireless LLN becomes apparent when you look at how LLN networks will be used. Applications include the Internet of Things (IoT), Smart Grid, Machine to Machine (M2M) communications, and vehicular information systems. In other words, the number of devices that connect these networks will be in the tens of billions. This course examines the key network protocols designed to operate in low power and lossy environment. Protocols covered include, IEEE 802.15.4, Bluetooth Low Energy, ZigBee, 6LoWPAN, RPL, WirelessHart, ISA100, and LoRaWAN. This course is a 2-day course on LLN, as part of the Wireless Course offerings at CellStream. This class is ideal for anyone looking for skills and knowledge on wireless LLNs or needing to understand the technologies that are enabling the Internet of Things (IoT).  See the course details here.

ZigBee is a set of specifications that define how small low power devices communicate. It is a leading standard for the connectivity of wireless sensors, control and monitoring networks for home and industrial automation. Applications include controlling light switches, patient monitoring, smart energy, and traffic management systems.

ZigBee builds on the IEEE 802.15.4 Wireless Personal Area Network (WPAN) standard, adding network and application layers, as well as application objects and cluster libraries that allow vendors to customize their solution. This course takes a layered approach to explaining how ZigBee networks work. It starts with a detailed explanation of the 802.15.4 physical and MAC layers. It then takes the student through the evolution of ZigBee network layer, covering ZigBee 2007, ZigBee PRO, and ZigBee IP.  See the course details here.

The IEEE 802.15.4 is the dominant wireless standard for sensor products and networks that are being deployed in homes, industrial environments, and utility networks. It is the wireless technology that underlies most sensor networks, including ZigBee, ISA-100 Wireless, WirelessHART, and Wi-SUN.

This course details the 802.15.4-2003 and 2006 MAC and PHY. It compares and contrasts the operational differences between a beacon-enabled network and a non-beacon enabled network. The course also cover the 802.15.4e,g enhancements, which extend the 802.15.4 PHY and MAC specification to meet the industrial control and smart metering application requirements. While ZigBee is based on the earlier 802.15.4 specifications, these enhancements provide the base on which the WirelessHART, ISA100-wireless, and WiSUN specifications are built. See the course details here.

The course begins with an explanation of the different standards activities focused on vehicular communications. It then focuses one of the most important standards; theIEEE 802.11p and the  IEEE 1609 standards for Wireless Access in Vehicular Environments (WAVE).

IEEE 802.11p WAVE is an amendment to the 802.11 standards to support wireless communications in a high speed vehicular environment. IEEE 1609 WAVE provides the higher layer standards to support fast reliable messaging over an 802.11p wireless network, supporting applications such as electronic toll payments, the broadcast of safety and traffic information, and vehicle-to-vehicle (V2V) communications.

This class is ideal for anyone looking for skills and knowledge on WAVE or needing to understand the technologies that are enabling the Internet of Things (IoT).  See the course details here.

Wireless Internet Service Providers emerged to fill a competitive role for Internet Access.  This course focuses on the fundamentals of what it takes to operate a WISP or add WISP functionality to a wired/fiber network.  From tower planning, backhaul network design, planning and operational tools, to key skills, this course provides a fundamental understanding of what it takes to operate and maintain a WISP.

Wireless LAN Operations and Maintenance support skills are key to anyone working in the Service Provider or Enterprise maintenance and operations roles.  This course focuses on WLAN implementation, maintenance, and troubleshooting using state of the art tools and lab exercises to practice and develop skills students can then utilize in their job functions.
