## Summary
Mobile radio telephone is a family of pre-cellular wireless communication technologies that connect to the public switched telephone network (PSTN). It is classified as a mobile phone generation and is commonly referred to as “0G.” It was followed by 1G, the first generation of wireless cellular technology.

## Key Facts
- Mobile radio telephone is described as a “family of pre-cellular PSTN wireless communication technologies.”

- It is also known by the alias **0G**.
- Another listed alias is **“Radio telefono movil.”**
- It is **followed by 1G**, the first generation of wireless cellular technology.
- The topic’s main category is **Category:Mobile radio telephone systems**.
- The Wikipedia title is **“Mobile radio telephone.”**
- It has a recorded **sitelink count of 17**.
- It appears across multiple Wikipedia language editions, including **en, es, fr, ar, ca, cs, fa, fi, he, ko**.
- Identifiers include **Freebase ID /m/04gt__** and **Microsoft Academic ID (discontinued) 155207387**.

## FAQs
### Q: What is a mobile radio telephone?
A: A mobile radio telephone is a family of pre-cellular wireless communication technologies that connect to the PSTN. It is commonly grouped under “0G” and is categorized as a mobile phone generation.

### Q: Is mobile radio telephone the same as 1G?
A: No. Mobile radio telephone refers to pre-cellular PSTN wireless communication technologies (often called 0G). It is followed by 1G, which is the first generation of wireless cellular technology.

### Q: Why is it called “0G”?
A: “0G” is listed as an alias for mobile radio telephone. The label is used to denote that it is pre-cellular and comes before 1G in the sequence of mobile phone generations.

### Q: How is mobile radio telephone classified?
A: It is classified as a **mobile phone generation**, which is a class representing generations of wireless telephone technology. It is specifically described as pre-cellular and PSTN-connected.

## Why It Matters
Mobile radio telephone matters because it represents a distinct stage in wireless telephony: pre-cellular systems that still provided wireless access to the public switched telephone network (PSTN). As a “family” of technologies rather than a single standard, it captures the broader category of early mobile radio-based telephone systems that existed before the first cellular generation. This makes it a useful reference point for understanding how mobile communications evolved in generations, with mobile radio telephone (0G) explicitly positioned as being followed by 1G. In knowledge organization terms, it anchors the transition from pre-cellular wireless telephone approaches to cellular-era generations, and it provides a clear classification within the “mobile phone generation” concept. For researchers, educators, and technical historians, it helps distinguish PSTN-connected pre-cellular systems from later cellular technologies, and it provides a stable entity for cross-referencing across Wikipedia and external identifiers.

## Notable For
- Being defined as a **family of pre-cellular PSTN wireless communication technologies** (not a single technology).
- Serving as the **predecessor generation** to **1G** (the first cellular generation), via the “followed by” relationship.
- Being commonly known as **0G**, explicitly listed as an alias.
- Having a dedicated topical grouping: **Category:Mobile radio telephone systems**.
- Being represented across multiple Wikipedia language editions (including English, Spanish, and French).

## Body
### Definition and Scope
- **Mobile radio telephone** refers to a **family** of wireless communication technologies.
- These technologies are **pre-cellular**.
- They provide wireless communication connected to the **PSTN (public switched telephone network)**.

### Classification in Mobile Technology Generations
- **Instance of:** *mobile phone generation* (a generation of wireless telephone technology).
- **Alias:** *0G*.
- This positions mobile radio telephone as a generation category that predates cellular generations.

### Relationship to 1G
- **Followed by:** **1G**.
- **1G** is described as the **first generation of wireless cellular technology**.
- This relationship explicitly places mobile radio telephone before the cellular era in the generational sequence.

### Names and Identifiers
- **Wikipedia title:** Mobile radio telephone.
- **Aliases:** 0G; Radio telefono movil.
- **Freebase ID:** /m/04gt__.
- **Microsoft Academic ID (discontinued):** 155207387.

### Categories and Cross-language Presence
- **Topic’s main category:** Category:Mobile radio telephone systems.
- **Wikipedia languages listed:** ar, ca, cs, en, es, fa, fi, fr, he, ko.
- **Sitelink count:** 17.
