This session will provide a quick review of the methodology of early dispatch systems connected to radio, telephone and other resources via circuit switched interfaces such as 4WE&M, 2W analogue etc., and their restricted backhaul capabilities, leading on to the 'stand-alone' RoIP boxes that allowed 4W E&M to be converted to IP and recovered at the other end allowing backhaul via more flexible IP networks.
The next technology is dispatch systems with native IP connectivity allowing the most flexible and functional interfaces between the dispatch system and its connected resources. While some manufacturers equipment uses proprietary IP messaging, most prefer and use open standards such as P25 CSSI (console sub system interface), DFSI (digital fixed system interface) and ISSI (inter sub system interface) or the emerging DMR AIS which ensures that different vendors equipment can interoperate with each other via these interfaces. Open standards provide end users with greatly improved competitive choice and functional capability on these systems.
The session will explore examples of IP interfaces for voice dispatch systems and the functions supported, plus give a background on how these apply to many different technologies and can even be adapted for conventional radio applications:
The workshop will cover on the following issues:
- The difference between RoIP and VoIP - how radio systems differ from phone systems
- Implementing one-to-one connections
- Implementing many-to-many connection
- Risk management: Identifying network issues affecting RoIP/VoIP quality; maintenance; and redundancy
- Design elements :- building blocks; calculating network bandwidth requirements
The implications of RoIP for dispatch consoles will be also be discussed: how dispatch console to radio connections can be implemented with RoIP and how RoIP can be used to provide fault tolerant dispatch architectures.
Finally the workshop will look at the impact of new technologies such as IPv6, Wireless Broadband and the switch to Digital Radio on the RoIP landscape.

1) The commercial value chain prioritizes cellular operators and consumers over enterprise users, though this is changing.
2) Device models are optimized for single home access points rather than enterprise wireless LANs with multiple access points.
3) Battery life is overly prioritized, limiting probing for better access points and adoption of features like QoS that could improve performance.
This guide explains how to implement an Aruba 802.11n wireless network that must provide high-speed access to an auditorium-style room with 500 or more seats. Aruba Networks refers to such networks as high-density wireless LANs (HD WLANs). Lecture halls, hotel ballrooms, and convention centers are common examples of spaces with this requirement. Because the number of concurrent users on an AP is limited, to serve such a large number of devices requires access point (AP) densities well in excess of the usual AP per 2,500 – 5,000 ft2 (225 – 450 m2). Such coverage areas therefore have many special technical design challenges. This validated reference design provides the design principles, capacity planning methods, and physical installation knowledge needed to successfully deploy HD WLANs.
Computer networks allow users to share resources and to communicate. Can you imagine a world without emails, online newspapers, blogs, web sites and the other services offered by the Internet? Networks also allow users to share resources such as printers, applications, files, directories, and storage drives. This chapter provides an overview of network principles, standards, and purposes. IT professionals must be familiar with networking concepts to meet the expectations and needs of customers and network users.
You will learn the basics of network design and how devices on the network impact the flow of data. These devices include hubs, switches, access points, routers, and firewalls. Different Internet connection types such as DSL, cable, cellular and satellite are also covered. You will learn about the four layers of the TCP/IP model and the functions and protocols associated with each layer. You will also learn about many wireless networks and protocols. This includes IEEE 802.11 Wireless LAN protocols, wireless protocols for close proximity, like Frequency Identification (RFID), Near Field Communication (NFC), and smart home protocol standards like Zigbee and Z-wave. This knowledge will help you successfully design, implement, and troubleshoot networks. The chapter concludes with discussions on network cable types; twisted-pair, fiber-optic, and coaxial. You will learn how each type of cable is constructed, how they carry data signals, and appropriate use cases for each.
It is important to not only learn about computer network operation and components but also to build hands-on skills. In this chapter you will build and to test a straight-through Unshielded Twisted-Pair (UTP) Ethernet network cable.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
