(News from)Application of IP-based wireless intercom in disaster rescue emergency communication
question:More and more enterprises are involved in disaster reliefIP wireless intercommachine as keyIntroduction of communication equipment.
The background for the introduction of IP wireless walkie-talkies is the lessons learned from the Great East Japan Earthquake and the increase in strong typhoons and frequent earthquakes in recent years.IP wireless walkie-talkieThe data network of the mobile operator is used for communication, so the call range covers the mobile network range of the whole country.So why chooseIP wireless walkie-talkieInstead of a normal cell phone?will be explained nextIP wireless walkie-talkiespecialty.
IP wireless communication
Unlike ordinary mobile phones, IP wireless communication can perform group communication.
By setting up branch or department groups in advance, even in an emergency, you can contact each terminal just by pressing the send button, avoiding confusion.
Audio communication is basic, and some devices can also share video and images.
when traffic increases
In the event of a disaster, traffic on many networks increases dramatically.
IP wireless communication does not use the voice channel of the mobile phone, but uses the data channel to communicate. Data communication is controlled separately from voice communication, and even if the traffic volume of voice communication increases, the control of data communication is usually adjusted minimally. Therefore, there is also less impact on communications during times of disaster.
What is the working principle of IP wireless walkie-talkie?
The IP wireless walkie-talkie uses the mobile phone network or the Internet network, and the audio is divided into data packets (audio data is compressed and turned into small packets) for communication. By reducing the size of the audio data, multiple communications can be implemented on one wire. However, normal audio communication will occupy a line, resulting in reduced capacity for simultaneous connections. The MVNO (Mobile Virtual Network Operator) commonly used in IP wireless machines also has the feature of being unrestricted.
Ordinary mobile phone
Less capacity for simultaneous connections since one line and one port are occupied
IP wireless walkie-talkie
A port can accommodate multiple lines, so the capacity for simultaneous connections is greater.
Communication path of IP wireless walkie-talkie
The communication path of IP wireless communication refers to the transmission path of data and information in the wireless network. This depends on the IP wireless equipment used and the provider.
In general, IP wireless communication uses data communication instead of traditional voice communication. It transmits by dividing audio or information data into small data packets (packets). These data packets are transmitted over wireless networks such as Wi-Fi, mobile networks (such as 4G or 5G), or specific dedicated wireless communication networks.
When using IP wireless communication, the communication route may be a closed network or an open network. A closed network consists only of specific wireless communication systems and is not connected to the public Internet. This method is usually used in applications that require high security and communication stability, such as corporate internal communication or disaster emergency communication. An open network, on the other hand, is usually connected to the public Internet, enabling communications to be communicated more broadly across regions and geographic locations.
Introduction of IP wireless call mode
There are two communication modes for IP wireless devices, namely simplex communication (Simplex) and duplex communication (Duplex). (*Some models may not have duplex function.) In the call mode, there are three modes of broadcast call, group call and individual call to choose from.
Other functions
The following are optional functions of IP wireless communication. (*Different device specifications may vary.)
- Acquisition of location information: The location information can be obtained through GPS and displayed on the map.
- Simultaneous and Conference Calls: Conference room-style communication between multiple parties is possible.
- Priority call (forced barge): A terminal with a higher priority can barge into a radio that is in a call.
- Dispatcher function: audio and video communication can be performed between the IP wireless terminal and the management PC. The PC will be an IP wireless terminal, so the video sent by the terminal can be confirmed on the dispatcher software, and follow-up instructions can be given.
- App: By installing a smartphone app, voice communication with other IP wireless dedicated machines is possible.
Call recording and video playback.
Summarize:
IP wireless communication devices do not require a license or personal qualification. It is a next-generation wireless communication device as a general business and emergency communication device for enterprises and local governments. No need to worry about interference and noise, it is strongly recommended that you experience the reliable and secure IP wireless communication equipment through the free demo machine.
