An increasing rate of mobile customers, new IP-based services, and growing demands for greater coverage areas have created constant challenges for mobile operators. To effectively meet customer demands while protecting investments and delivering a rapid profit requires a flexible, cost-effective, and reliable core transport network. Microwave Networks offers a complete line of point-to-point microwave radios to help meet existing network demands while easing the transition to new 3G networks and beyond.

Core Transmission Networks
Point-to-point microwave radio is the medium of choice for mobile infrastructures worldwide. The many benefits of microwave radio include rapid roll-out and deployment, minimal operational costs, and the ability to quickly and easily upgrade capacity without service disruptions. These factors underline the ability of microwave radio to provide operators with a dedicated transport network and eliminate the need to lease expensive and often unreliable circuits from local fixed-line providers.

Converged Services
One of the major influences in mobile network evolution is the introduction of next-generation voice, data, and video services. Increasingly, these services are being offered through converged IP, packet-switched devices. Unfortunately for many operators, most of the existing mobile infrastructures are based on circuit-switched technology. The amount of investment in these networks is tremendous and moving to IP-based services appears to many to be a long and costly process.

Microwave Networks offers a practical solution to these real-world issues. With our flexible and integrated line of point-to-point microwave radios, MNI is able to transport both traditional, circuit-switched, T1 and E1 traffic simultaneously with newer packet-switched, IP data. Those operators who have a single transport network to handle both types of traffic have a tremendous advantage as networks migrate from the traditional voice-only to new 3G networks.

Having a single method of transport eliminates the need for a second 'overlay' network. This can be quite expensive and rapidly drain any profits as well as become a nightmare to maintain. Our approach to scalable capacity upgrades through plug-in data modules also helps to maximize your return on investments by allowing you to 'pay-as-you-grow'. A typical scenario is as follows:

Starting with only a few voice circuits, operators can easily increase their number of T1s or E1s as subscribers are added and demand increases. When moving to integrated services becomes part of the business plan, another simple module addition allows the addition of IP traffic. Finally, as the migration to complete packet-based transport is required, the circuit-switched modules can be replaced by IP modules. This complete cycle can be accomplished without changing the base radio saving time, money, and retaining the needed quality of service.

Base Station Access
For base station access solutions, MNI offers the Proteus AMT L-Series product line. The L-Series is ideal for last-mile access applications while offering greater capacity and flexibility than most radios in its class. Using adaptive modulation and a flexible architecture, Proteus AMT L-Series operates in the 6-38 GHz bands with capacities starting from 2 x T1/E1 up to 50 Mbps. This includes many combinations of circuit switched data up to 16 x T1/E1s, 1 x DS3/E3, in addition to 50 Mbps Ethernet IP and other narrowband IP rates.

High-Capacity Backhaul and Ring Topologies
For higher capacity backhaul networks, MNI offers the Proteus AMT-M-Series product line.

M-Series operates in either all-indoor configurations at 6, 7, 8, and 11 GHz or in split-mount configurations from 6 to 38 GHz. Using 2 Line Interface Module (LIM) bays, each radio offers a choice of data rates from 2 to 190 Mbps in any combination of nxDS1/E1, nxDS3/E3, SONET/SDH, or VLAN Ethernet. Fully-protected Hot-Standby configurations with errorless switching are also available for data-critical applications.

Our Dynamic Payload Mapping^TM (DPM) suite of features allows detailed data provisioning and routing with options such as drop-insert, DS1/E1 loop protection, and internal cross-connect. DPM also allows the user to easily change the allocation of data as needed to achieve the desired distribution of DS1/E1, DS3/E3, and Ethernet traffic.

Whatever the application, MNI is dedicated to creating the most cost-effective and reliable network transport infrastructures for mobile operators worldwide.
