Verizon Wireless Private Network
This paper explains how Verizon Wireless private network solutions can be deployed using the Verizon Wireless CDMA2000 1xRTT and EV-DO networks. The following private network-related areas are described:
- CDMA2000 1xRTT and EV-DO technology
- Enhancements that Verizon Wireless offers on its network
- Options available to customers using private networks
This paper begins with an overview of CDMA2000 1xRTT and EV-DO technology that provides sufficient information for any reader who simply wants a high-level understanding of a CDMA network. The paper will then explore in detail the Verizon Wireless private network solutions that use the network, and available customer options.
This paper has been developed for enterprise customers, IT administrators, decision makers, and other personnel. It is assumed that the reader has an understanding of CDMA2000 1xRTT and EV-DO technology and some understanding of computer and network concepts.
2. CDMA2000 1xRTT And EV-DO Network And Technology Overview
Over time, more and more demands have been made on the capabilities of corporate networks. Workers want more mobility, high-speed access, and an extension of applications across the enterprise, all of which can strain current IT capabilities.
Verizon Wireless understands these demands and has constantly improved its mobile data network to offer increased mobility, access, and applications. This process is ongoing, but it pays to see what’s happened before to gain a greater appreciation of the capabilities of today’s mobile data network.
Early second-generation (2G) CDMA-based wireless networks have proved their effectiveness in delivering high-quality voice traffic to subscribers. These early 2G networks were known as cdmaOne or IS-95 after the interim standard that defined cdmaOne.
Shortly thereafter, voice users wanted basic data services, which prompted the various industry players to join together to meet this demand. A set of global wireless data standards and specifications was developed to define the methods and techniques required to offer circuit-switched data services to subscribers. These methods and standards formed the basis for third-generation (3G) wireless communication and are defined by a set of independent International Telecommunications union (ITU) recommendations. These ITU recommendations for CDMA networks are collectively known as the International Mobile Telecommunications-2000 (IMT-2000) standards framework.
In 2000, the IMT-2000 standards framework was implemented on a CDMA wireless network, becoming the very first commercially available, 3G circuit-switched data service to be deployed based on these global standards. On CDMA networks, these 3G data services are typically referred to as CDMA2000 or IS-2000.
The CDMA2000 wireless air interface standard is known by many terms, including: 1x, 1xRTT, IS-2000, CDMA2000 1x, and CDMA2000. The designation 1xRTT is frequently used to identify the version of CDMA2000 radio technology that operates over 1.25-MHz radio channels (one times 1.25 MHz).
The first phase of CDMA2000 is called 1xRTT. 1xRTT almost doubles the voice capacity over IS-95 networks and provides basic data services conforming to the IMT-2000 standard for UMTS (universal Mobile Telecommunications System) services, delivering data at near-broadband speeds over mobile wireless communications networks. 1xRTT provides maximum theoretical data rates of 144 Kbps (downlink) and 144 Kbps (uplink), as well as twice the voice capacity on a single 1.25-MHz CDMA channel.
