The wireless voice communication Mesh system mainly includes the following applications:
1. Mobile office phone:
Through the construction of wireless SIP system, it means that the staff has a portable mobile office phone. When a leader or staff dials the office phone, even if the staff is not in the office or at home or abroad for study and study, as long as the WI-FI terminal is connected to the Internet Can answer office calls, and truly achieve efficient and flexible mobile office requirements.
2. Significant savings in communication costs:
To save a lot of money for corporate offices, whether it is an internal user or various committees and units within the government, you can enjoy rich multimedia communication services only by paying for the broadband Internet access;
The users of the enterprise information service support system can not only realize multimedia communication between each other, but also multimedia instant communication with any SIP user provided by any service provider in the world. Therefore, all office environments, business personnel and There will be no need to pay any telephone charges when making calls or holding conference calls between various overseas offices, etc., which can greatly reduce office call costs.
3. Wireless emergency trunking communication function:
With the support of the removable Mesh wireless broadband network, the current wireless trunking function will be supplemented. The staff can access the Internet to query information through the Wi-Fi multimedia terminal no matter where they are, can access the corporate office system for mobile office, can answer their own office phone, can open a conference call at any time, and can be like a digital trunked intercom Press a key to realize the multi-party call function.
4. Rich value-added services:
The complete multimedia instant communication service provided by the wireless SIP platform can be integrated into the enterprise office OA system, and the provided service means further enhance the functions of the existing paperless office system.
The combination of advanced MESH technology and SIP technology with the widely used ITERET network provides advanced information exchange methods for the rapid development of enterprises, and also creates potential possibilities for the diversity of business offices.
As the main manufacturer of R & D and promotion of the third-generation wireless LAN technology, Strix has carried out large-scale deployment in wireless cities, wireless parks, public security emergency and other environments in North America, Europe, and Japan; Cellular grid network) technology makes this large-scale deployment of a wide area possible.
The Access / Oe wireless network based on Mesh technology supports completely wireless network construction, can quickly set up a wireless network, and has the characteristics of high mobility and rapid deployment; compared with traditional wired and wireless network technologies, it is greatly reduced The initial installation and deployment costs.
Wireless voice network design
The voice subsystem should be composed of the following parts:
Voice control system
l Telephoy Gateway
l IP Telephoy Server
Wireless mobile voice terminal
As the control system of the voice network, the voice gateway and voice server are placed in the computer room as long as the network connectivity is guaranteed.
Using the wireless network system to provide wireless signal coverage in the work area, wireless mobile voice terminals can freely make voice dialing and answering voice scheduling needs within the network, and quickly provide real-time voice services.
Through the coverage of Strix Access / Oe outdoor wireless base station, the coverage radius of more than 250 meters can be achieved in the open space to meet the requirements of large-scale use in the plant.
The voice control system located in the computer room will include a voice gateway and a voice server. All voice traffic from wireless mobile voice terminals is aggregated to the voice control system through the wireless network system. Among them, the voice server is responsible for implementing the signaling control of wireless voice terminal registration and call establishment, and the voice gateway is responsible for processing the interaction between the wireless voice network and the existing voice network, so that the wireless mobile voice terminal can realize the interconnection with the fixed telephone .
In order to ensure that Wi-Fi mobile phones can still make voice calls outside the coverage of wireless base stations, it is recommended to use professional high-sensitivity 2.4GHz Wi-Fi mobile phones.
The advantages of wireless Mesh technology are:
Wireless Mesh networks support point-to-point, point-to-multipoint, mesh networking and other topologies
Support large-scale networking-wireless scale networking of tens of square kilometers or even hundreds of square kilometers
High-performance Mesh network with multiple wireless technologies, multiple frequency points and multiple sectors
Industry-leading high-performance networking-provides multiple 802.11a wireless modules for wireless backhaul and aggregation infrastructure to ensure that the bandwidth loss per hop wireless network is less than 10%
Multi-sectors provide overall network performance-The fiber point location uses multi-sector networking technology (3 sectors, 6 sectors, etc.) to fully inject the bandwidth resources of the fiber points into the wireless Mesh network
Strong anti-interference ability-use the intelligent frequency scanning and multi-frequency planning capabilities of Strix OWS devices to avoid interference problems in wireless Mesh network systems; cooperate with sectors and directional antennas to reduce Mesh relay links and wireless return points Opportunity for outside interference
safety
Wireless Mesh base station equipment interconnection security
Multiple security mechanisms for wireless user access
Manageability
Simple and convenient management-unified network management system across three layers of networks, batch configuration, unified configuration
Support unified SMP network management, support multiple functions such as events and alarms
Network self-healing and automatic performance adjustment
Use Layer 2 Mesh technology for networking, distributed intelligence to quickly establish Mesh topology and convergence network
Self-healing and automatic link performance adjustment, network self-healing or Mesh link switching will not cause user service interruption, no manual participation is required
Quick switch
Supports roaming and switching of Wi-Fi handheld devices at ground speed
Using Strix vehicle node, it can support high-speed movement and switching at 240 kilometers per hour; vehicle node supports high-performance and high-security networking, and supports multiple VLA functions
Flexible networking
Flexible use of multiple RF technologies and frequency bands
Multi-level networking-The wireless Mesh network consists of three layers of networking to form a three-dimensional, hierarchical distributed wireless Mesh network architecture. Take the urban wireless networking as an example:
u Mesh convergence layer at the height of the tower on the top of the wireless building
u Mesh distribution layer along the height of the lamppost along the street
u Mesh access layer for roads, communities and parks, hot spots and indoors
Can meet the installation and equipment interconnection at different heights
Support different types of antennas-omnidirectional antenna, plate antenna, sector antenna and parabolic antenna to achieve wireless Mesh device interconnection and network coverage Network flexibility and multi-level networking.
