Traditional microwave frequency bands are becoming highly congested, and as this is overwhelmingly in support of mobile backhaul applications, it will become increasingly difficult to find available microwave spectrum.
At the same time, as Radio Access Network technology evolves toward LTE/LTE-Advanced, much higher capacity is going to be required in the mobile backhaul and fronthaul networks.
Thus the 70/80 GHz frequency range, called E-band, is growing in importance.
E-band is ideal to deliver multi-Gigabit capacity transport in current and future networks, for the following reasons:
Fujitsu is one of the world’s leading microwave radio providers and has developed an innovative, patented “Impulse Radio” technology for millimetre-wave radio transmission.
This technology, incorporated in highly compact outdoor radio equipment, makes possible an ultra-high data rate of over 3 Gbps for a wireless link.
All GX4000 systems operating in the E-band frequency feature Fujitsu’s Impulse Radio technology, and provide quick and easy solutions for building multi-Gigabit wireless networks.
The GX4000’s simple architecture means that the system offers not just high speed transmission but also low power consumption - so you can establish and maintain a green network.
A Fujitsu GX4000 E-band radio solution will redefine your network for tomorrow.
1. Backhaul in Mobile/Fixed Broadband Networks
Microwave links are vital in providing cost-effective backhaul to 3G/4G macrocells that cannot justify a direct fibre connection. An E-band link is an ideal complement to wired backhaul technology, as it provides enough transmission capacity to support radically increased data traffic demands within a short timeframe.
2. Fronthaul in Future Mobile Networks (CPRI Transport)
In the age of LTE and LTE-Advanced, the architecture of a radio access network will be quite different from that of today. In that age small cells will be widely deployed as an overlay onto the macrocell layer for overall network operations efficiency. The most serious challenge for mobile network operators will no longer be the backhaul, but rather the fronthaul: i.e., how to secure inter-connections between a centralised-BBU and multiple RRH in the most efficient way.
With the arrival of GX4000 technology from Fujitsu, you can meet that challenge - while at the same time reducing CapEx - with a flexible, environmentally-friendly wireless solution.
3. Portable Networks for Disaster Recovery, Low Latency Transport, etc.
Wireless transport solutions can be extremely important if a communications network is heavily damaged by disaster and infrastructures must be quickly restored. With its compact body and user-friendly operation, the GX4000 represents a very flexible and powerful solution for emergency recovery of data traffic. The GX4000 is also an ideal solution for latency-sensitive but capacity-demanding applications like Financial Trading networks or HDTV transport.
