Difference between IDEN and CDMA Network Technologies

One of the most important considerations for any modern business is reliable communication. In order to make sure that your team can stay in touch, you need to invest in a good communications system. Two of the most common network technologies are IDEN and CDMA. But what’s the difference between them? Let’s take a closer look.

What is IDEN Network Technology?

IDEN network technology, also known as Integrated Digital Enhanced Network, is a wireless network technology that was developed by Motorola. IDEN uses both time division multiple access (TDMA) and frequency hopping spread spectrum (FHSS) to provide two-way radio communication, as well as data services such as text messaging and packet data.

IDEN supports a maximum data rate of 45.45 kbps and a maximum voice capacity of 30 users per cell. IDEN networks are typically used by public safety agencies, such as police and fire departments, as well as by businesses with private mobile radio systems. In recent years, IDEN has been replaced by newer technologies, such as LTE and WiFi, in many markets. However, IDEN remains an important part of the mobile landscape in some areas.

What is CDMA Network Technology?

CDMA Network Technology is a communication standard that allows for the transmission of data over a CDMA network. CDMA, or Code Division Multiple Access, is a type of multiplexing that allows for multiple signals to be sent over a single channel. This makes CDMA ideal for use in mobile networks, as it allows for more efficient use of limited bandwidth. CDMA networks are used by many major wireless carriers, including Verizon and Sprint. While CDMA technology is not as widely used as GSM, it provides a number of advantages, including improved call quality and increased battery life.

Difference between IDEN and CDMA Network Technologies

IDEN and CDMA are two different types of network technologies. IDEN is a packet-based technology that uses TDMA to provide voice and data services. CDMA is a spread spectrum technology that uses code division multiple access to provide voice and data services. IDEN is typically used for carrier-specific applications such as the Nextel Walkie-Talkie service, while CDMA is used for general-purpose applications such as cellular telephony. IDEN has a higher capacity than CDMA, but it is also more expensive to deploy and maintain.


Although both IDEN and CDMA are network technologies, they differ in a few key ways. First, the way calls are handled is different- with IDEN, each call has its own channel, while CDMA combines multiple calls into one data stream. This difference can affect call quality and how many people can be on a call at once. Additionally, whereas IDEN uses Time Division Multiple Access (TDMA), CDMA relies on Code Division Multiple Access (CDMA). Finally, IDEN is slowly being phased out as carriers move to newer technologies like LTE, while CDMA is still going strong.
