Microwave networking platform simplifies mobile operator networks
A purpose-built microwave router, the CTR 8540 features a powerful combination of microwave transport, Layer 2 Carrier Ethernet and Layer 3 IP/MPLS routing — all in one box.
Aviat has already received orders for the CTR 8540 from Osnova Telecom of the Russian Federation and Entel in Chile. Deliveries are scheduled to commence within the coming weeks.
According to Michael Pangia, president and CEO, Aviat Networks, the CTR 8540 combines the functionality of five separate devices and supports 50 percent more radio interfaces and twice as many Gigabit Ethernet ports as any other microwave platform and delivers up to 4 Gbps of aggregate capacity per link.
Further, the CTR has an open, software-based architecture, so it can be deployed now as a Layer 2 microwave device, with IP/MPLS functionality capable of being added when required via simple software upgrade. CTR leverages MPLS traffic engineering to offer SDN (software-defined networking) backhaul resource management and optimization, which provides a practical migration path to SDN architecture over time.
"As they drive new generations of high capacity microwave into the backhaul for 3G and LTE, L2 will not be sufficient for the long term needs of many mobile operators," says Patrick Donegan, senior analyst, Heavy Reading. "In a recent Heavy Reading survey of mobile operators using microwave backhaul, we found that 42 percent of mobile operators believe that L3 is ‘very likely’ to be needed in the access layer of the backhaul within three years."
