Aprisa SR+ Migration Master Station

Industrial Wireless Router Migration System

FCC, IC, ETSI Bands 

The Aprisa SR+ Migration Master Station (MMS) provides a smooth migration from legacy radio networks to next-generation Aprisa SR+ SCADA radio networks utilizing existing frequencies and antenna infrastructure. From the very first remote radio replacement enjoy market-leading Aprisa radio features in terms of speed, coverage, security, IP, and advanced management options. Your network is no longer limited to performing in a crippled backward compatibility mode. 

Benefit now by migrating your network smoothly with the minimum of cost and downtime, using existing frequencies and antennas. Leverage your maintenance budget to get real performance and feature set upgrades. Legacy vendor backward compatibility solutions lead to a staged upgrade program, only achieving promised improvements and investment return at the end of the project at which point the network will be behind today’s next-generation Aprisa SR+ performance and feature set. Think forwards not backward!

The MMS system comprises two main components, the standard Aprisa SR+ protected or non-protected master station and the new migration switch, a fully redundant RF switch. The MMS is installed side-by-side with the legacy master station. The new Aprisa SR+ network uses the same frequencies and antenna as the existing radio network. The migration switch connects to the RF antenna and shares this with the legacy master or the Aprisa SR+ master station as required by the remotes. The migration switch is managed by the advanced logic in the Aprisa SR+ protected master station. All SCADA traffic is directed through the Aprisa SR+ master, which passes traffic destined for the legacy network to the legacy base station in addition to setting the migration switch for the antenna.

Key Features

• Secure: with its defense-in-depth approach including AES encryption, authentication, address filtering, and user access control, the Aprisa SRi protects against malicious attacks and consumer-grade wireless vulnerabilities.
• Flexible hopping channel and zone arrangements: full band and reduced non-overlapping zone options allow a tailored approach to interference mitigation. The unique combination of advanced forward error correction (FEC) with packet synchronized selective ARQ combats interference. Time-sliced fast hop and advanced access control MAC delivers more usable throughput and reduced latency.
• Future-proof: the Aprisa SRi supports dual serial and dual Ethernet ports in a single, compact form factor, designed to cryptographically secure legacy serial, protect existing device investment, and enable new applications. Old and new application protocols can be run side by side.
• Aprisa SR family: the Aprisa SRi is fully integrated with the Aprisa SR family and includes all family features including networking, management, and security. Maximize your experience with reduced training and time to value.
• Advanced L2 / L3 capabilities: selectable L2 bridge, L3 router, or advanced gateway router combination L2/L3 modes with VLAN, QoS, NAT, and filtering attributes to maximize capacity in constrained bandwidth and prioritize mission-critical traffic while meeting tough security and IP network policy imperatives.
• Link efficiency: Adaptive Coding and Modulation (ACM) and forward error correction maintain the integrity of the wireless connection while an effective channel access scheme and advanced IP routing features ensure efficient transfer of data across the Aprisa SRi network.
• Reliable and robust: the Aprisa SRi requires no manual component tuning and maintains its performance over a wide temperature range using full specification industrially rated components and shared Aprisa family heritage.
• Easily managed: an easy to use GUI supports local element management via HTTPS and remote element management over the air, and SNMP support allows network-wide monitoring and control via a third-party network management system.
