SLAMSITE91 RTN 910 basic configuration unit 16 * E1 (75 ohms) + 2 * FE (RJ45) + 2 * GE (RJ45) with IDU

Huawei's RTN 900 series is the industry's first TDM/Hybrid/Packet/Routing integrated IP microwave product. It can meet voice transmission requirements in the 2G era, voice and data transmission requirements in the 3G era, as well as broadband data transmission requirements in the LTE era, effectively protecting operator investments in infrastructure.

1. All-IP: Full Service Transmission, Smooth Network Evolution
As the industry's first IP microwave product that supports E2E MPLS-TP and IP/MPLS (L3VPN), RTN 900 can be used to build connectivity-oriented packet networks. It supports unified transmission of TDM/ATM/IP services and smooth evolution to packet networks, allowing operators to fully utilize existing network infrastructure.

RTN 900 takes the lead in supporting both high-precision IEEE 1588v2 and synchronous Ethernet, meeting phase and frequency synchronization requirements of 2G, 3G, and LTE base stations. This feature means less GPS equipment is needed on the base station side, reducing GPS deployment and maintenance costs, which in turn reduces network TCO.

2. Ultra Broadband: Efficient Mobile Backhaul

RTN 900 uses hitless adaptive modulation (AM), which supports switching among 13 levels of modulation schemes (QPSK to 4096QAM), to adjust bandwidth based on link quality over air interfaces. This feature enhances the spectral efficiency. Compared with the fixed modulation mode, the AM technology increases transmission bandwidth six-fold.
RTN 900 applies the cross polarization interference cancellation (XPIC) and four-layer frame header compression technologies. With these technologies, the maximum capacity of a channel can reach 2.5 Gbit/s, providing large bandwidth for mobile backhaul.
With enhanced physical link aggregation (EPLA), RTN 900 can aggregate a maximum of 12 IF links, enabling load sharing of up to 10 Gbit/s Ethernet services and meeting the bandwidth requirements of LTE.

3. Networking Microwave Solution, Reducing CAPEX and OPEX
RTN 900 has a built-in TDM/packet dual-bus switching platform, which can implement E2E switching of TDM and packet services, allowing quick service provisioning and multi-direction networking.
RTN 900 and optical transmission equipment can be managed by a unified NMS, enabling E2E service deployment. Huawei also provides full-outdoor microwave solutions, providing the right gear for each deployment area.
Up to September 2014, Huawei had deployed 1 million microwave hops in more than 100 countries for over 30 of the top 50 global operators.
