    The history of the walkie talkie spans nearly ninety years of engineering development. This timeline documents every major milestone from the earliest portable field radios through World War II deployments, commercial and public safety adoption, digital standards, hybrid radio–cellular systems, and modern smart radio platforms.The 2020s introduction of the Walt Smart Radio System by weavix marks the point where the walkie talkie moves from a basic voice device to a fully connected communication tool capable of handling voice, video, data, and integrated safety functions.

    Walkie Talkie Evolution by Decade

    From Donald Hings and Alfred J. Gross, through wartime Motorola field sets and digital standards,
    to the Walt Smart Radio System by weavix. One timeline of how portable voice communication evolved.

    1. 1937

      Donald Hings builds the first portable packset

      Trail, British Columbia, Canada

      Donald Hings designs a backpack portable radio for remote mining operations. This packset is widely regarded as the beginning of the history of the walkie talkie and proves that mobile person to person radio is practical.

    2. 1938

      Alfred J. Gross develops FM portable radios

      United States

      Alfred J. Gross works on compact FM radio systems. His focus on frequency modulation improves audio clarity and resistance to interference and becomes an important foundation in walkie talkie evolution.

    3. 1940

      Motorola SCR-300 backpack radio

      Galvin Manufacturing, later Motorola

      Engineers at Motorola build the SCR-300, a VHF FM backpack radio used by Allied troops. Journalists call it a walkie talkie and it becomes one of the first widely deployed field radios in the walkie talkie history timeline.

    4. 1941

      SCR-536 Handie Talkie becomes first handheld

      World War II, Allied forces

      The SCR-536 Handie Talkie arrives as a one person handheld radio. It weighs about five pounds and is used during amphibious landings and short range infantry communication.

    5. 1943 – 1945

      Walkie talkies reshape Allied battlefield tactics

      European and Pacific theaters

      Allied forces deploy tens of thousands of backpack and handheld radios. Real time coordination between infantry, artillery, and aircraft becomes possible and walkie talkies shift from experimental devices to essential battlefield tools.

    6. 1945

      Surplus radios enter civilian use

      Post war transition

      After the war, surplus military walkie talkies are sold into civilian markets. Police, fire, civil defense, and amateur radio operators adopt them and build the first public safety and industrial two way radio networks.

    7. 1947

      Transistor invention and miniaturization

      Bell Labs

      The transistor replaces fragile vacuum tubes in radio circuits. Radios become smaller, cooler running, and more efficient, which is critical for the next phase of walkie talkie evolution.

    8. 1962

      Motorola HT-200 transistor handheld

      Commercial and public safety markets

      Motorola introduces the HT-200, often called the brick. It is one of the first fully transistorized handheld walkie talkies and becomes a standard professional radio for police, utilities, and industrial users.

    9. 1977

      FCC opens 49 MHz for consumer radios

      United States regulation

      The FCC moves consumer walkie talkies to the 49 MHz band to separate them from Citizens Band activity. This change drives a surge in family and toy walkie talkies and brings the technology into everyday life.

    10. 1980s

      Walkie talkies become common consumer devices

      Global consumer markets

      Miniaturized components and mass production make inexpensive walkie talkies widely available. They appear on construction sites, at events, in warehouses, and in homes as simple push to talk communication tools.

    11. 1990s

      Digital Mobile Radio and Project 25

      Professional and public safety radio

      Digital Mobile Radio and Project 25 introduce digital modulation for two way radios. Audio quality improves, encryption becomes common, and multiple talk paths can share the same channel. This is the start of the digital walkie talkie history era.

    12. 2000s

      Hybrid radio and cellular systems

      Enterprise communication

      Gateways link land mobile radio networks with cellular and satellite infrastructure. Organizations extend push to talk communication across regions and countries without relying only on local radio coverage.

    13. 2010s

      Push to talk over cellular

      LTE and early 5G networks

      Push to talk over cellular platforms such as Zello and carrier enhanced services bring walkie talkie style communication to smartphones. LTE and early 5G networks carry group calls across very large geographic areas.

    14. 2020s

      Walt Smart Radio System by weavix

      Smart radio and connected frontline communication

      The Walt Smart Radio System by weavix introduces an enterprise grade smart radio that integrates voice, video, data, safety sensors, and IoT connectivity in one platform. The device acts as an intelligent edge endpoint that links frontline workers directly to cloud based analytics, safety systems, and workforce applications. This marks a new phase in walkie talkie evolution where the radio becomes a smart, networked communication hub.
