JoMobile SD Mobile Multimedia Communication System
JoMobileSD Mobile Multimedia Communication System (“JoMobileSD”) provides real-time and simultaneous transmission of broadband multimedia services, including VIDEO, VOICE, and IP-based DATA, under the high-speed moving environment. It features large coverage, high sensitivity, excellent mobility, strong anti-interference and anti-fade capabilities, high data-rate, high stability and reliability. The system demonstrates itself an ideal solution for long distance, high quality, high-data rate and wireless real-time transmission, which is required in emergency communications and NLOS wideband data transmission. Therefore, it’s widely used in government key sectors,, including public security, anti-terrorism, armed police, fire control, field battle troop, as well as transportation, customs, oil field, mine, and power .
JoMobileSD System Characteristics
TDD- Time Division Duplex
Shared uplink/downlink frequency, adjustable uplink/downlink bandwidth, flexible service applications
Turbo Codes- High Performance Error Correction Coding
Error correction performance closes to the theoretical limit and greatly promotes the system sensitivity
HARQ- Error Control Mechanism
Transmission data rate is automatically adjusted to the current status of the transmission channel so as to ensure channel connectivity.
IP-based Wireless Transparent Transmission
Any equipment compliant with IP and Ethernet protocols could be applied in the system. Flexible application interface fits multiple services, including image, voice and data, which grounds well for future system upgrade.
Advanced Anti-fading Technology
RAKE diversity anti-fading technology ensures communication quality under complicated moving environment..
JoMobileSD Technical Features
Strong diffraction capability: NLOS operation ensured
Excellent mobile performance: real on-road test speed more than 500km/h and specially fit for the requirements of high-speed moving environment, such as air-borne, vehicle-born and fleet-borne.
Strong receiving capability: Multiple advanced diversity technologies, greatly enhances its anti-fading ability and ensures its advantageous Rx sensitivity under complicated working environment. With RSL at -100dm, EFR could still be less than 1%.
Large coverage: under typical urban mobile environment (NLOS), coverage of single base station could be up to 30km; under LOS environment, maximum coverage could be 100km.
Strong anti-interfering capability: under complicated electromagnetic environment, excellent communication quality could still be maintained; with C/N at 0dB, the system could still operate normally.
Bi-directional communication capability: JoMobileSD is the bi-directional communication system and could provide uplink/downlink service transmission.
Allocable channel resource: Communication frequency could be allocated with no hardware replacement.
Support IP-based multimedia composite service transmission including wideband data service; support unidirectional and bidirectional image transmission, bidirectional voice transmission and bidirectional data transmission.
Flexible operation: multi-status monitoring and setting could be achieved; system installation and commission is quick and convenient.
Multiple networking solutions provide end-to-end integrated solutions: multiple application modes, including PTP, PTMP, multi-center coverage, relay transmission, enable the system to access users’ LAN, WAN and video conference system, so as to form the real large coverage of mobile multimedia communication network.
Networking roaming potential: upon present technical basis, JoMobileSD will release neo-generation product with networking roaming capability.
