Digital GSM Abis Backhauling
The Right Alternative to Basic TDMMemotec's Radio Access Network (RAN) Optimizer cellular backhaul solution offers a simple yet compelling alternative to basic TDM Drop and Insert mechanisms for reducing RAN transmission costs. Our solution is based on bandwidth optimization, shared packet transport multiplexing, and network interface adaptation.
Get the Backhaul Flexibility of 3G RAN Networks – CX-UMemotec's platform features a unique packet gateway and bandwidth optimization solution designed for digital GSM Abis BTS to Base Station Controller (BSC) links. It gives 2G/2.5G cellular operators the backhaul flexibility of 3G RAN networks and allows them to achieve packet-based bandwidth efficiencies without compromising service integrity and voice quality. Memotec's GSM Abis optimizer solution is particularly suited when connecting BTSs or cluster of BTSs through expensive transmission facilities such as long distance leased lines or satellite links, where it can achieve up to 3:1 bandwidth reduction without any loss of voice quality.
A plug and Play Technology Agnostic Option – AbisXpressThe proprietary nature of the Abis interface and the related sensitivity of the different radios utilized have often delayed the field deployment of Optimization and Compression solutions thereby incurring revenue loss to Mobile Operators. The latter are also looking to an all-IP evolution path and do not want to make investments for a short term benefit. A Few Key Features
The minimal configuration of AbisXpress provides a unique plug-and-play deployment mode. As it operates on the transmission level, AbisXpress is independent of the Abis structure and protocol for ubiquitous total infrastructure vendor transparency. And without sacrificing anything on performance side, this new Memotec solution can be rapidly and easily deployed in ANY network. It operates in a connectionless environment, thus eliminating another layer of complexity of connection management. AbisXpress features superior optimization of resources for overall cost reduction.
Get More Revenues - Today
A quick and easy deployment will allow faster revenue generation and fewer constraints on the operations teams, optimization performance and integration with the operator’s network. Future-proof by design, it gets revenues flowing faster, lowers Opex and keeps Capex under tight control.
Converges and Aggregates all Services
Being able to converge and aggregate all new services & technologies into a single resource is key, as well as the ability to provide media adaptation to the different access transmission technologies available today and in the future.
*Existing Memotec customers already enjoying the benefits of actual Memotec GSM Abis optimization feature can also be upgraded to take advantage of the AbisXpress features. Simplify Network Operation and Reduce CostsScale your network along your traffic and service growthOperators need to be prepared for changes in network size, traffic types and technology changes. Memotec's RAN Optimizer solution is specificaly qualified for the job. Our platforms can be deployed quickly and transparently to the existing RAN transmission infrastructure, and then scaled with ease (without reconfiguring the network) to meet demand.
The Memotec platform is perfect for:
Aggregate Multiple Wireless ServicesDesigned to aggregate multiple wireless services types, our platformes efficiently carry the emerging IP-based services (WiFi, WiMAX, HSDPA), that will evolve as part of the 3G migration and broadband wireless convergence. Simple Configuration and Open ManagementIntuitive Provisioning and Maintenance OperationsMemotec's solution is easily deployed and configured using a centralized Graphical User Interface (GUI) Element Management System (EMS) that provides intuitive provisioning and maintenance operations. In order to further facilitate the turn-up of GSM access backhaul operations, Memotec's CX solution supports a "plug-&-play" auto-mapping feature, which automatically recognizes the traffic received by the Abis Interface card and provisions the unit with the required configuration data. Enhanced Network Operation and Service Quality
Memotec's CX RAN Optimizer features an essential added value to the Mobile Operator Network Operation Center (NOC): CXMON. CXMON is a built-in software probe that enables the operator to monitor precisely each Abis interface with real time graphic visualization of the different traffic being forwarded (signaling, voice, data). CXMON displays also real-time information on discarded frames and optimization ratio. As a result, CXMON allows the operator to control the quality of the service delivered over the RAN and fine tune the network efficiency for optimal cost effective utilization. Ater Link Backhaul OptimizationAggregate, Compress and OptimizeMemotec offers a complete solution for reducing the costs and/or increasing the capacity of voice and data trunks connecting BSCs to MSCs. Based on Memotec's CX gateway, Memotec's solution can aggregate, compress and optimize GSM 2G and 2.5G voice and data traffic at the A, A-ter and Gb/Gn interfaces. Up to 40% Ater Bandwidth SavingAt the Ater interface, Memotec's RAN Optimizer solution will reduce Ater bandwidth requirements by detecting and removing idle channels and silences in the voice traffic, offering up to 40% bandwidth savings per Ater link. The RAN Optimizer allows also a GSM operator to increase his Ater-link capacity by 50% transparently to the existing network transmission infrastructure, saving both on OPEX (recurring leasing costs) and CAPEX (additional equipments, network re-engineering and leasing upfront costs). 100% interoperability, transparencyMemotec's RAN Optimizer operates directly within the existing encoded Ater compressed voice channels and with minimal latency. Therefore, it guarantees 100% interoperability, transparency and no voice quality degradation. Memotec's solution is compatible with all the various GSM codecs currently available: FR, EFR, HR, AMR (FR and HR). In addition, the Memotec RAN Optimizer can also aggregate and compress SS7 signaling channels as well as GSM GPRS and EDGE data traffic at the Gb and Gn interface. After loss-less compression, the signaling and data traffic is multiplexed together with the Ater voice traffic on the same transport network infrastructure (Digital TDM, ATM or packet based), further increasing the overall BSC backhaul traffic bandwidth reduction, and cost savings. EDGEPlus: Expanding GSM ServicesThe Memotec CX Series offer GSM Cellular Operator a solution for deploying EDGE services on their existing RAN infrastructure, without changing the current network configuration or increasing their OPEX. As such, it enables the GSM cellular Operator to benefit from the additional potential revenue of high value, high-speed data users, while reducing the financial exposure associated with deploying a new service. AbisXtenderUse the Bandwidth you Need Not the Bandwidth You are OfferedAbisXtender is the new base station (BTS) backhaul paradigm for the GSM Cellular Operator- by Memotec. Now GSM BTS connection can be freed from the huge inefficiencies of costly permanently assigned digital T1/E1 backhaul lines. Instead, operators will use exactly the bandwidth they need-not the bandwidth they are offered-for each site and gain a tremendous advantage in operating costs, deployment flexibility and return on investment. This in return yields tremendous savings on network operating expenditure (OPEX), in particular when the average Radio Access Network (RAN) utilization is traditionally low, like rural or sparsely populated areas, as well as along communication lines (roads, railways, waterways). Profitable ARPU in Rural Deployment for GSM Mobile OperatorsAbisXtender enables GSM Mobile Operators to deploy profitable services in low density or low traffic profile areas where other traditional backhaul solutions fail. The additional benefits of satellite-based transmissions unique properties provide a competitive alternative to microwave and expensive long distance leased lines backhaul solutions.
AbisXtender's opens up a broad range of business opportunities and solutions for GSM Operators:
Lower the Cost of your Satellite BackhaulAbisXtender represents a tremendous business opportunity for Satellite Service Providers to tap into the multi-billion dollar GSM mobile operator backhaul service business. In developing countries, GSM operators are focused on shifting from urban areas to lower ARPU rural and remote areas. Providing reliable global GSM service coverage while reducing operation costs is key to sustaining a mobile operator's growth. The high Operating Expenditure (OPEX) typically associated with transponder usage lowers the profitability of such deployment, limiting its application to specific cases and interim fast service coverage deployment. Opens Up New Business OpportunitiesBy dramatically reducing GSM BTS satellite backhaul costs down to less than $1,000/month, and enabling new service model based on usage, Memotec's AbisXtender enables the use of satellite as a standard solution for providing global service reach. It also opens up new business opportunities like backup services, costly long-distance leased lines replacement, MVNO and maritime ship-to-shore applications. AbisXtender for Efficient and Low Cost Rural Cellular BackhaulWhen addressing the needs for rural or low-density area service coverage, cellular operators face specific challenges in terms of transmission availability and cost. Being insensitive to distance, satellite technology is ideally suited to serve rural area. It allows to minimize the number of sites and related CAPEX. But the cost of the associated satellite bandwidth is a critical barrier to satellite backhaul technology.
