While high capacity, high reliability and low hardware cost are important elements of all wireless and wired communications systems, the Modesat solutions are aimed foremost towards application in the following markets:
Microwave radio
In the coming years, wireless traffic is poised to grow exponentially. This is due in large part to the near-term transition towards 3,5G and 4G mobile networks, where wideband high capacity backhauling solutions will play a key role.
It is estimated that around 90% of microwave radio links presently used in backhauling solutions are low capacity ones. In view of the predicted sharp rise in wireless traffic, existing networks are not capable of meeting the throughput requirements. Modesat modems using 256QAM and even higher order modulation provide the capability to achieve the highest throughput in the industry.
Gigabit Ethernet
Wireless Gigabit Ethernet is mainly used as a last mile connection for wireless broadband transmission. It has become increasingly uncommon to build out cable transmission networks in cities, where information traffic is sharply increasing. Rather than invest in cabling, which is relatively costly and inflexible, wireless Gigabit links provide a feasible alternative.
In view of the emerging 4G networks and rising broadband internet traffic, the market for Gigabit Ethernet links is booming. However, existing wireless Gigabit modems are generally still based on analogue technology, while modern times require flexible digital solutions. For this market, Modesat offers a high capacity 16QAM digital Gigabit wireless modem.
Fixed Satellite communications
In view of the new DVB-S2 standard and transition towards HDTV transmission over satellite, capacity requirements for satellite channels are becoming ever more demanding. Although DVB-S2 specifies up to 32APSK modulation, practical realization of such higher order modulation schemes in satellite modems has now been prohibitively complicated.
Modesat offers 32APSK digital modem DSP Cores for high capacity satcomms applications.
Mobile Satellite communications
Whether train, airplane or land vehicle – all means of transportation have a growing need for mobile broadband communications to support future generation applications. The higher the speed, the more difficult it is to provide efficient high capacity links. Signal distortion due to Doppler effect is sufficiently large to seriously degrade operation of DVB-S2 modems when operating in mobile environments.
Modesat's pilot tone based synchronization scheme enables operation in mobile environments. The pilot tone acts as a reference for phase and amplitude synchronization, enabling to build high throughput broadband modems for mobile applications.
Cable networks
DOCSIS 3.0 foresees the use of higher order modulation schemes such as 1024QAM to enable higher throughput in cable network applications. However, transition to even higher capacity by use of yet higher order modulation is prohibitively complicated using existing technology.
Due to its efficient PilotSync™ technology, Modesat can offer up to 4096QAM in practical realizations. This technology thereby enables fast transition towards the extremely high throughput required by today’s dynamic cable network markets.
