Evdo what is

Qualcomm has produced impressive demonstrations of EVDO's capabilities. In one, a video conference was conducted with a participant traveling in a car at 60 mph 96 kph. Transferring the large amounts of data required for video conferencing is a major challenge, especially at such speeds. In another demonstration, a phone call was placed from a bullet train moving in excess of mph kph.

This approach can be less vulnerable to interception and jamming than some other wireless technologies. This protocol is considered 3. HSDPA shares one transmission channel between multiple users, and schedules data transfer to take advantage of the best possible conditions; this means that data may be sent to multiple users at the same time. Different speed versions of HSDPA are typically available to consumers, with download speeds ranging from 1.

As purchasing spectrum from regulatory agencies is extremely expensive, this brings down the cost of building and using new networks. HSDPA, while offering faster download speeds with the higher levels of service, may also be more expensive for the consumer. Users who will be traveling in foreign countries with wireless devices may want to check to see if they are supported on a given network.

For frequent travelers, it may be advisable to consider investing in a device that will work reliably on international networks in order to avoid problems with dropped calls, inability to send data, and other issues. As new wireless standards develop, the quality of wireless services tends to improve.

Various options are not available in all areas, and may have differing rates of performance. Software may need to be downloaded to the computer to enable tethering. When tethered to a computer, an EDVO phone acts as a modem.

Tethering usually incurs an additional fee charged by the wireless service provider. Like most current technology, EVDO continues to evolve to provide better, faster service. As wireless providers offer more robust services, the networks used to deliver them, such as EVDO, will most likely be upgraded as well.
