Wireless Backhaul

Address subscriber growth, migration plans, and service innovation

Wireless backhaul requirements are increasing the demand on existing networks. Wireless communications have quickly evolved from voice-only to a full multimedia experience leveraging intelligent handheld devices. The delivery of residential Internet access using wireless technologies such as WiMAX with speeds comparable to DSL or cable internet services is a growing trend. Rapid increases in subscribership—with an increasingly mobile and connected population—are generating exponential increases in bandwidth.

The network you need

Bandwidth intensive services, the need to deliver a high quality of experience, and the focus on improved Average Revenue per User (ARPU) is driving wireless and backhaul service providers to define key requirements for next generation backhaul networks.

Wireless user capabilities, such as mobile email, text messaging, image sharing, and web surfing have driven reactionary network overlays to address increased demand. Leverage the BTI 7000 Series’ “virtual fiber” to change to a strategic deployment plan and scale capacity with less lead time. Offering Coarse WDM (16λ) and Dense WDM (40λ), the BTI 7000 Series can cost-effectively address capacity for both core and aggregation components of backhaul networks.

Carrier Ethernet is increasingly prevalent in wireless and backhaul service provider networks as a cost-effective, high capacity data traffic offload connection from base station to MSC, overlaying existing TDM (SONET/SDH) connectivity. The BTI 7000 Series enables multi-layer convergence with the combination of Ethernet switching and WDM transport onto the same platform, eliminating expenditures for multiple layers of transport network equipment. Wireless and backhaul service providers require extensive service provisioning, Service Level Agreement (SLA) monitoring, and policy management capabilities to ensure connections are provisioned quickly and running efficiently. The BTI 7000 Series, leveraging the proNX Management Suite, delivers secure and flexible end-to-end management of backhaul networks with topology views, inventory control, fault management, service provisioning and security management.

Next generation backhaul architectures are focused on IP over Ethernet for fourth generation (4G) wireless. The BTI 7000 Series offers Layer 1 and Layer 2 Ethernet connectivity with high fan-in and up to 10GbE interconnect; BTI’s Carrier Ethernet implementation provides the scalability, SLA enforcement, OAM functionality, and capacity to ensure 4G readiness of today’s network deployments, simplifying migration strategies.
