IWAVE MANET PTT MESH system integrated the digital simulcast technology with ad-hoc network, which supply clear audio, seamless roaming and simple operation for rescue and public safety. It quickly sets up a temporary network for rescue and disaster response. It compatible with IP to starlink terminals for users remotely command & dispatch onsite staffs.
DMR and TETRA are very popular mobile radios for two way audio communictation. In the following table, In terms of networking methods, we made a comparison between IWAVE PTT MESH network system and DMR and TETRA. So that you can choose the most suitable system for your variety application.
| MANET Radio | DMR Radios | |
| Base Station Coverage Capability | Ultra-high sensitivity and 2-3times coverage of DMR radios | |
| Self-healing, self-forming mesh network | Centerless Self-healing, self-forming mesh network Wireless connection between multiple units base station. |
Not support mesh network. Using IP cable to connect multiple base stations togethe |
| Frequency interference between adjacent base stations | Frequency Awareness Technology Adjacent base stations can use the same frequency, and they can sense and avoid each other. |
Adjacent base stations cannot reuse the same frequency, which will cause interference. There is no advanced frequency sensing technology. |
| Power consumption | No control channel long transmission, low power consumption, support solar power supply | The control channel has a long transmission, which consumes a lot of power. The emergency backup power supply cannot be powered by solar energy. |
| Anti-destruction Capability | Strong anti-destruction ability.It does not rely on any fixed infrastructure, such as 4G/5G cellular network or optical fiber. Any base station can join in or leave the network any time. That will not affect the normal running of the entire system. | Weak anti-destruction ability.Rely on infrastructure and onece the disaster occurs, it will be easily affected and become unavailable |
| Network Expansion | An unlimited number of base stations can be added without increasing the frequency. | You need to configure or reuse frequencies to add base stations. Adding base stations is limited by frequency. |
| Utilization of frequency resources | High frequency utilizationA pair of frequencies is used by all the base stations to build a wide area networking with multiple channels. | A pair of frequencies can only be used by one base station and cannot be used by multiple base stations at the same time for wide-area networking coverage. |
| User capacity | Dynamically distribute capacity according to group number as needed | Not support |
| Base station backup | Base station dual-machine hot backup with the same frequency | Not support |
| Mutual positioning | Situation awareness and mutual positioning between mobile radio stations and vehicles in the coverage area | Not support |
| Fast deployment | When disaster occur, fast depolyment within 10minutes to expand the network to any place required. | Not support |
| Air wireless switching technology | Air wireless switching technology reduces the probability of data exchange failure to zero. | Not support |
| Channel congestion | No control channel. No channel congestion proble | When the call volume suddenly increases, the channel will be blocked and paralyzed. |
| The speed of initiate a call | Press PTT to quickly initiate a call | It is managed via the control channel, so the speed of initiate a call is slow. |
| Channel Allocation | Channel associated signaling technology, dynamic channel allocation with high efficiency. | Fixed control channel, fixed allocation channel, efficiency reduced by about 1/5 |
Conclusion
● The cost of wireless cluster communication system network is significantly reduced by dozens or even hundreds of times compared with traditional communication network, which completely solves the bottleneck problem of large coverage area of emergency communication network, small radio capacity and low cost performance of self-built network.
● The number of wireless base stations is greatly reduced, and optical fiber link system and mains power supply system are no longer needed, which greatly simplifies the complexity of the entire wireless communication system, reduces the workload of after-sales maintenance and the high cost of long-term maintenance.
● Technological innovation plays a vital role in promoting the development of new quality productivity, especially in building cost-effective emergency communication system network. Cluster communication system is not only an important means to enhance the government's emergency management capabilities, but also helps to
