CDMA, Code Division Multiple Access, uses advanced mathematical techniques to allow multiple wireless devices to transmit simultaneously on the same frequency. Every device, such as a cell phone, is assigned a unique mathematical signature. It applies this signature to the original signal and transmits the modified signal. A receiver applies the inverse of the mathematical operation to recover the original signal.
Traditional wireless networks create a physical path between receiving and sending devices, much like traditional telephone networks. EVDO instead adopts the same approach used for the internet. IP, the Internet Protocol, breaks data into small pieces called packets. Each packet is sent independently of all the other packets. This saves bandwidth for use by other devices; when neither party on a phone call is speaking, the connection consumes no bandwidth because there are no packets to send. Or, when an internet web site is accessed, no bandwidth is used until the site starts sending the web page.
A significant advantage of EVDO over competing technologies is that it uses the same broadcasting frequencies as existing CDMA networks. As purchasing spectrum from regulatory agencies is extremely expensive, this brings down the cost of building and using the new networks.
CommVerge Solutions has strategic partnership with best of breed equipment manufacturers and has extensively proven its capabilities of building a robust and efficient CDMA network infrastructure from BTS to EVDO Core network, CommVerge has been continuously evolving with the technology and understands what it takes to build one.
