The portable projector has a built-in independent Wi-Fi hotspot function, supporting simultaneous connection and casting of multiple devices, realizing multi-person interactive projection and sharing and greatly improving the equipment’s multi-scene application capability. Traditional projectors can only connect to one mobile phone or computer device for casting at a single time, which cannot meet the needs of multi-person sharing and multi-content switching in meetings and group activities. The built-in hotspot of this projector can independently form a local wireless network, allowing multiple mobile phones, tablets and laptops to connect to the projector hotspot at the same time.

The multi-device connection function supports free switching of casting devices. Multiple users can connect to the projector hotspot in advance, and switch the projection screen with one click according to the use needs, realizing seamless switching of different meeting materials, video resources and picture content without repeated connection and disconnection, which greatly improves the efficiency of business meetings, team sharing and student group discussions. The built-in hotspot has strong signal stability and large connection capacity, which can support 5-8 devices to connect at the same time without network congestion, casting lag and picture distortion, ensuring smooth multi-device interactive projection.

Moreover, the built-in hotspot can work independently without external network support. Even in network-free environments such as outdoor camping, temporary field meetings and remote activity sites, it can realize multi-device wireless connection and casting. It not only meets the multi-person sharing needs of outdoor entertainment and team activities, but also improves the efficiency of mobile office and teaching demonstration. The independent hotspot + multi-device connection integrated function makes the projector’s interactive performance more powerful, fully adapting to the diversified use needs of family gatherings, business office and outdoor group activities.
