Mobile Backhaul Migration to Packet Transport

Mobile Backhaul Migration to Packet Transport

Your Needs
Migrate mobile backhaul to high-capacity Ethernet and MPLS packet transport networks over xDSL and fiber to reduce mobile backhaul operating expenses and deliver mobile broadband, HSPA and rich content services.

Our Solution
RAD enables a balanced migration to packet transport mobile backhaul, as well as substantial savings in operating and capital expenses, with an extensive portfolio featuring cell-site gateways (CSGs) and aggregation site gateways (ASGs). Connecting several base stations and node Bs at one end and aggregating BSC and RNC traffic at the other end, RAD’s ACE-3x00 multiservice cell-site gateways simultaneously deliver 2G and 3G services across Ethernet, IP or MPLS backbones, using pseudowire technology. Introducing “any service any port” functionality, RAD’s CSGs and ASGs incorporate flexible port configuration to capitalize on carriers and operators’ existing assets, including legacy TDM/ATM infrastructure and widespread, low-cost DSL equipment. This includes traffic separation over hybrid PSN and TDM/ATM transport, to allow a gradual migration to all-IP radio access networks.

Benefits

  • Substantially boost bandwidth capacity to accommodate rollout of new cellular services and avoid the mobile broadband bottleneck

  • Leverage packet transport’s scalability and flexibility for an efficient service upgrade

  • Offset network expansion outlay and stagnant ARPU by curbing backhaul transport costs with cost-efficient PSN backbones, optimized transport efficiency, traffic grooming and overbooking, as well as 2G/3G colocation

  • Provide robust clock synchronization per ITU-T G.823 and G.824 specifications, and support Synchronous Ethernet and IEEE 1588v2 distribution protocols

  • Eliminate interworking and interoperability issues with a single platform for multi-generation traffic

  • Support SLA-based quality-of-service (QoS) and traffic prioritization per service

  • Ensure network is primed for fixed and mobile convergence (FMC) and new UMTS 3GPP, WiMAX standards

Backhaul 2G Base Stations over an Ethernet Ring

Backhaul 2G base station traffic over an Ethernet ring

Your Needs
Reduce 2G mobile backhaul costs by using Ethernet ring technology to connect base stations to Metro Ethernet or MPLS backbone

Our Solution
RAD’s IPmux-24 and IPmux-216 TDM pseudowire gateways can support up to 16 nodes in a ring topology with sub-50 millisecond protection switching time. Where fiber is deployed in the access, it is possible to build an Ethernet ring to backhaul 2G base station traffic.

Benefits:

  • Highly accurate clock recovery to synchronize base stations to one clock source

  • Provides resiliency in case of fiber cut between the nodes in the ring

  • Enables easy replacement of obsolete SDH access ring without massive fiber re-trenching

  • Support multi-generation, multi-operator collocation at the same tower

  • Enhance service reliability through network resiliency and redundancy

2G/3G/4G Mobile Backhaul Aggregation over ATM

2G/3G/4G Mobile Backhaul Aggregation over ATM

Your Needs
Benefit from 2G/3G/4G mobile backhaul aggregation over ATM using statistical multiplexing capabilities to improve backhaul performance and reduce transmission costs by simultaneously delivering 2G, 3G and future 4G generations over ATM backbones


Our Solution
RAD’s ACE-3100 multiservice cell-site gateway, ACE-3105 multiservice cell-site gateway, ACE-3200 multiservice cell-site gateway, ACE-3205 multiservice cell-site gateway, ACE-3220 multiservice cell-site gateway, ACE-3400 aggregation site gateway, and ACE-3402 aggregation site gateway connect cell-sites and controller sites to ATM backbones, over shared access lines. Featuring “any service any port” functionality, they incorporate flexible port configuration to allow grooming of full or fractional E1/T1 UNIs, several IMA links and DSL lines into a single IMA or STM-1/OC-3 network interface. This ensures the most economical allocation of backhauling resources and the delivery of multi-generation traffic over ATM networks. RAD’s RAN gateways leverage ATM’s inherent QoS attributes to enable service differentiation and traffic engineering, including prioritization, shaping and scheduling. In addition, they support ATM statistical multiplexing and allow operators to optimize network utilization by implementing overbooking strategies, thereby reducing service costs and operating expenditures (OpEx).

Benefits

  • Support end-to-end traffic monitoring and QoS assurance

  • Reduce CapEx through better utilization of existing ATM equipment, requiring fewer E1/T1 links

  • Reduces OpEx by aggregating multiple services onto a single network interface

2G/3G Base Station Transport Solutions

2G/3G Base Station Transport Solutions

Your needs
Connectivity solutions for 2G and 3G base stations via a single access link over varied infrastructure.

Our solution
RAD has connectivity solutions for transporting mobile traffic from colocated 2G and 3G base stations over any infrastructure: copper, fiber or wireless. Offering connectivity in a compact, one-box solution, RAD's SHDSL modems and multiplexers, fiber multiplexers and wireless multiplexers transmit 2G and 3G voice and data traffic over E1/T1 and Ethernet links via any available media (copper, fiber, wireless). These solutions fit the needs of mobile operators with own fiber, copper or wireless access links (mainly for suburban and rural areas).

Benefits

  • Reduced OPEX with single access link for multiple types of cellular base stations

  • Backhauling over any available access media (copper, fiber, wireless)

  • End-to-end connectivity solutions

2G, 3G, 4G Convergence over PDH, SDH, SONET

Saving Transport Costs through Multiservice Aggregation

Your Needs
Converge 2G, 3G and 4G traffic over available PDH and SDH/SONET infrastructure to deliver legacy 2G cellular applications and new mobile broadband services, in order to minimize transport expenses and shorten service roll-out times.

Our Solution
RAD’s RAN backhaul solutions for 2G, 3G and 4G convergence over PDH, SDH and SONET allow operators to capitalize on legacy TDM installed base, to streamline large volumes of mobile traffic and simultaneously deliver 2G, 3G and future 4G services. RAD’s ACE-3x00 multiservice cell-site gateways (CSGs) and aggregation site gateways (ASGs) were specifically designed to help mobile operators and transport providers substantially reduce backhaul expenses. They enable efficient delivery of real-time traffic (e.g. voice and video streaming) and delay-tolerant services (e.g. IP, Internet surfing) over a single network link, with different quality-of-service (QoS) parameters set for each service.

RAD’s RAN backhaul solutions are ideal for mobile operators who own their transport links as well as for providers who lease lines from a local carrier.

Benefits
  • Accommodate the upsurge in bandwidth capacity without massive capital investments, through better utilization of pre-deployed SDH/SONET equipment

  • Reduce CapEx by conserving existing resources and trimming down the number of leased services, using lower-priced, higher bit-rate STM-1/OC-3 ports in network edge switches

  • Enable cost effective multi-generation service integration

  • Lower OpEx by simplifying network architecture and improving link efficiency, requiring fewer technician truck rolls

  • Ensure carrier-grade services with flexible redundancy options, including full system protection
