Challenge


Challenge

Organizations have used numerous forms of communications in efforts to increase productivity. Simple push-to-talk (PTT) solutions were an early answer; advances in technology have also introduced instant messaging, text messaging, unified communications, and collaboration applications as ways to perform group communications.
Some reasons organizations have shifted away from PTT are to attempt to reduce costs by using their existing IT infrastructure for mobile communications or to improve collaboration with mobile personnel by giving them voice, instant messaging, and video capabilities in addition to PTT services.
Pushing a button to instantly connect to a group is making a comeback; many organizations are returning to push-to-talk (PTT) instant communications to drive operational productivity in their environments. But organizations need a better PTT solution. New alternatives from carriers require a monthly fee. In addition, they might not provide coverage in all areas, hampering communications when it really counts.

Business Benefits

The Cisco ® Instant Connect solution provides an economical alternative to service provider solutions for mobile communications. Your organization deploys land mobile radio (LMR)-over-IP software in the data center. This software enables mobile personnel within your Wi-Fi coverage area to participate in PTT sessions using a Cisco Unified Wireless IP Phone or an Android device with a Wi-Fi connection. In addition, personnel who are out of the coverage area can use nearly any analog or digital radio or a smartphone or tablet with a 3G or 4G cellular connection or satellite connection.
Major benefits of Cisco Instant Connect include:

Low costs: Instead of paying a monthly service provider fee for onsite personnel, you deploy an on-premises solution. The savings from eliminating monthly fees quickly pays back the one-time capital investment. The Cisco solution is based on open standards, eliminating the need to purchase, support, and manage proprietary solutions.

More control of the wireless coverage: Cisco Instant Connect can be expanded for in-building coverage by adding Wi-Fi access points, integrating to carrier PTT service, bridging to LMR channels, and connecting to satellite radios.

High quality of experience: Cisco Instant Connect integrates with your existing Cisco Unified Communications and Cisco Collaboration services. Quality of service (QoS) and advanced voice codecs help to provide clear voice quality, even when the network is busy. Cisco CleanAir® technology constantly identifies and works around sources of wireless interference that might otherwise affect the user experience.

Improved collaboration and situational awareness: Mobile personnel can access PTT, voice, video, and instant messaging from multiple devices, including personal smartphones and tablets if your organization has a bring-your-own-device (BYOD) policy. Private/individual PTT sessions can be supported through Cisco Wireless IP Phones in addition to group PTT sessions. Combining PTT with rich-media applications can improve decision making and situational awareness.

Scalability: Cisco Instant Connect can support thousands of users. Managing a single system saves time and money compared to managing multiple service provider contracts, and the Android administrator privilege makes it easy to add and remove talk group users.

Security: Cisco Instant Connect encrypts all PTT communications between the wireless access point and the Cisco Unified Wireless IP Phone using the Advanced Encryption Standard 256 (AES-256) and Wi-Fi Protected Access (WPA2) security standards. Users over carrier networks can use Cisco AnyConnect® to establish a VPN session between the mobile device and the system.

High availability: If PTT is mission-critical in your organization, take advantage of high-availability options for the wireless network, server, applications, and Cisco Unified IP Phones. For example, if the signaling connection to the server drops, the Cisco Unified IP Phone can automatically reconnect to a secondary server, avoiding service interruptions. In addition, mobile personnel can swap out the Cisco Unified Wireless IP Phone battery in the field, an option not available with many service providers' PTT alternatives.

Increased integration through use of open standards: Cisco Instant Connect is based on the Session Initiation Protocol (SIP) standard, avoiding the interoperability, integration, and performance problems associated with proprietary encoding schemes.

Solution

With the Cisco Instant Connect solution, mobile workers within your facility's Wi-Fi coverage area can press a button on a Cisco Unified Wireless IP Phone 7925G or 7926G to participate in PTT sessions with each other and with people outside the coverage area who are using radios, smartphones, or tablets (Figure 1).

Cisco Unified Wireless Network

Since 2010, Wi-Fi networks have provided the high performance to support high-quality voice and video. Cisco wireless networks also deliver enterprise-quality manageability and scalability. You can connect new 802.11n devices as well as older devices based on 802.11a/b/g standards. To provide an excellent user experience, the included Cisco CleanAir technology continually identifies interference sources, such as microwave ovens and neighboring wireless networks, and automatically works around them. And Cisco Prime infrastructure solutions make it easier to monitor and manage the user experience by providing visibility into applications, users, and end devices.

How does Cisco Instant Connect Work?

Figure 2.

Cisco Certified Partners install virtualized PTT back-end software on servers in the corporate network. This software runs on the Cisco Unified Computing System in a virtual machine configuration. After the software is installed, an administrator will add people and radio channels, creating virtual talk groups based on business communication needs. Next, the smartphone users download the free Cisco Instant Connect software from the Google Play store. Once the PTT user logs in from their smartphone, they have instant access to their talk groups.
Cisco Instant Connect works with users on Cisco wired and wireless IP phones connected to the Cisco Unified Communications platform. These users can log in, join talk groups, and push a button to instantly communicate with the users on that talk group. Cisco Instant Connect can integrate to existing LMRs through the use of a donor radio connected to a Cisco router. Cisco Instant Connect can also integrate with a carrier-based PTT service by connecting a donor radio to a Cisco router with an LMR (E&M) card. Optionally, customers can add a full-featured touchscreen dispatch console that allows dispatchers to talk and listen on many channels at the same time.
Major solution components include the Wi-Fi network, PTT endpoints, and Cisco IP Interoperability and Communications Solution (IPICS).

Cisco IP Interoperability and Collaboration Solution

Used by public and private sectors since 2006, Cisco IPICS is an open-standards-based solution for communications interoperability. It enables people to join PTT talk groups from Cisco Unified IP Phones; any type of radio; iPhone, iPad, and Android devices; and laptops with client software. A new media engine provides go-ahead tones and busy tones to PTT users. Authorized personnel, such as supervisors, can use an intuitive interface for incident administration, including adding users to groups, adding video cameras to incidents, and activating policies.
Deploy Cisco IPICS centrally to provide PTT services to multiple offices, reducing management overhead and the need for local IT support. Or, if you need PTT services in just a few locations, you can implement multiple Cisco IPICS servers.

Text Box: Cisco IPICS: Time-Tested Interoperability Solution in the Public and Private SectorsCisco IPICS provides communications interoperability in more than 450 organizations, including:●	National military and security agencies●	National, state, and local public safety agencies●	Federal, state, and local emergency management agencies●	National and state departments of transportation and airports●	Educational institutions●	Healthcare organizations●	Manufacturers
