General Packet Radio Service (GPRS) is a 2.5G/3G packet-switched protocol + (meaning that information is split up into multiple packets similar to TCP/IP on the general internet). + It is the evolution of the 2G Global System for Mobile Communications (GSM), + which is the competitor to Code-Division Multiple Access (CDMA, also known as CDMAOne).

Global System for Mobile Communications (GSM) is a 2G standard. + It is the competitor to Code-Division Multiple Access (CDMA, also known as CDMAOne). + GSM eventually evolved into the 4G Long-Term Evolution (LTE), which was also adopted by CDMA networks.

High Speed Downlink Packet Access (HSDPA) + is a 3.5G protocol that makes up one portion of the High Speed Packet Access (HSPA) update to the 3G + Universal Mobile Telecommunications System (UMTS). + It is a competitor to the 3.5G Evolution-Data Optimized (EVDO) protocols.

High Speed Packet Access Plus (HSPAP) is a boost to the 3.5G + High Speed Packet Access (HSPA) update to the 3G + Universal Mobile Telecommunications System (UMTS). + It is a competitor to the 3.5G Evolution-Data Optimized (EVDO) protocols.

High Speed Uplink Packet Access (HSUPA) + is a 3.5G protocol that makes up one portion of the High Speed Packet Access (HSPA) update to the 3G + Universal Mobile Telecommunications System (UMTS). + It is a competitor to the 3.5G Evolution-Data Optimized (EVDO) protocols.

Integrated Digital Enhanced Network (iDEN) was a 2G protocol developed to work around some of the limitations of the 2G + Global System for Mobile Communications (GSM).

Interworking Wireless LAN (IWLAN) + is a fancy name for using an 802.11 Wi-Fi network to route cell phone data.

Long-Term Evolution (LTE) is the 4G evolution of the 3G + Universal Mobile Telecommunications System (UMTS). Notably, it replaced both UMTS, + which descended from the 2G Global System for Mobile Communications (GSM), as well as the 3G + Code-Division Multiple Access 2000 (CDMA2000), which was the main competitor to UMTS. + For the first time, this meant that cell phone networks worldwide coalesced around a single protocol, removing the need for world travelers to carry a phone with dual radios. + One reason LTE was able to achieve this was by supporting a mixed-mode network, where CDMA2000 (or UMTS) was used for voice calls and LTE for data communications. + This provided a seamless upgrade path for cell phone operators. Over time, most carriers eventually switched to Voice over LTE (VoLTE).

5G New Radio is the main 5G protocol. + It is the successor to the 4G Long-Term Evolution (LTE). + It is the first wireless protocol to generally include the generation (5G) in the name. +

Time-Division Synchronous Code-Division Multiple Access (TD-SCDMA) is an extension to the 3G + Universal Mobile Telecommunications System (UMTS), + which is the 3G successor of the 2G Global System for Mobile Communications (GSM) + and a competitor to the Code-Division Multiple Access 2000 (CDMA2000) standard. + TD-SCDMA was only used in China. + UMTS evolved into the 4G Long-Term Evolution (LTE), which was also adopted by CDMA networks.

The network type is unknown.

Long-Term Evolution Advanced Pro (LTE-A Pro) + is a 4.5G update to the 4G LTE protocol.

Long-Term Evolution Carrier Aggregation (LTE CA) + allows a 4G LTE connection to aggregate non-contiguous blocks of spectrum to increase data throughput.

There is no additional network information. Usually this category only applies to certain 4G and 5G networks.

New Radio Non-Standalone (NR NSA) uses the + 4G LTE protocols for the control channel and 5G NR for the data channel. + It provides much of the speed of 5G without any of the additional security benefits. + Android phones will list this as a 5G connection, but it is not protected against modern stingray attacks.

New Radio Non-Standalone millimeter Wave (NR NSA mmWave) uses the + 4G LTE protocols for the control channel + and 5G NR on the mmWave spectrum (24.25â52.6 GHz) for the data channel. + It provides much of the speed of 5G without any of the additional security benefits. + Android phones will list this as a 5G connection, but it is not protected against modern stingray attacks.

IMSI catchers, also known as stingrays, are fake cell phone towers that intercept your traffic and spy on you. + Each generation of cell phone protocols has attempted to mitigate stingrays, but each has generally failed. + With 5G, more of the traffic is encrypted in such a way that it prevents stingray spying. However, 5G networks can run in a blended 4G/5G mode, + where the control channel is 4G and the data channel is 5G. This is known as 5G NR NSA (5G New Radio Non-Standalone) mode. + When connected to such a blended network, + a cell phone is not protected against modern stingray attacks.

The Android status bar does not differentiate between 5G modes. It will display the same 5G icon for Standalone and Non-Standalone networks. + The purpose of Privacy Cell is to make it easy to tell what type of network you are connected to. + If you are in an area where you usually are connected to a 5G NR SA network and Privacy Cell shows a 5G NR NSA connection, + it is possible that a stingray has performed a downgrade attack to spy on your communications.

It should be noted that paltry attempts have been made to secure cell phone protocols in the past, which have never been sufficiently well designed to provide real protection. + Even if you are connected to a 5G NR SA network, it is likely that there are still unknown weaknesses in the network that can be exploited by a sufficiently funded adversary. + Privacy Cell will be updated regarding these types of vulnerabilities as future research identifies them.
