caption_attribution_description: Our new Kyocera EVDO router -- for those long road trips where we all sit around and tinker with our laptops, cell phones, Ambient devices, etc. The device is nifty enough to come with a 12V cigarette lighter power supply (of course, all of us do have 110 VAC outlets in our cars...)
context_page_description: Evolution-Data Optimized is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 standard which supports high data rates and can be deployed alongside a wireless carrier's voice services. It uses advanced multiplexing techniques including code division multiple access as well as time division multiplexing to maximize throughput. It is a part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world particularly those previously employing CDMA networks. It is also used on the Globalstar satellite phone network.
  EV-DO service was discontinued in much of Canada in 2015.
  An EV-DO channel has a bandwidth of 1.25 MHz, the same bandwidth size that IS-95A and IS-2000 use, though the channel structure is very different. The back-end network is entirely packet-based, and is not constrained by restrictions typically present on a circuit switched network.
context_section_description: Evolution-Data Optimized (EV-DO, EVDO, etc.) is a telecommunications standard for the wireless transmission of data through radio signals, typically for broadband Internet access. EV-DO is an evolution of the CDMA2000 (IS-2000) standard which supports high data rates and can be deployed alongside a wireless carrier's voice services. It uses advanced  multiplexing techniques including code division multiple access (CDMA) as well as time division multiplexing (TDM) to maximize throughput.  It is a part of the CDMA2000 family of standards and has been adopted by many mobile phone service providers around the world  particularly those previously employing CDMA networks. It is also used on the Globalstar satellite phone network.
  EV-DO service was discontinued in much of Canada in 2015.
  An EV-DO channel has a bandwidth of 1.25 MHz, the same bandwidth size that IS-95A (IS-95) and IS-2000 (1xRTT) use, though the channel structure is very different. The back-end network is entirely packet-based, and is not constrained by restrictions typically present on a circuit switched network.
  The EV-DO feature of CDMA2000 networks provides access to mobile devices with forward link air interface speeds of up to 2.4 Mbit/s with Rel. 0 and up to 3.1 Mbit/s with Rev. A. The reverse link rate for Rel. 0 can operate up to 153 kbit/s, while Rev. A can operate at up to 1.8 Mbit/s. It was designed to be operated end-to-end as an IP based network, and can support any application which can operate on such a network and bit rate constraints.
