Fault-Tolerant Public Safety System
November 22, 2017
First responders require seamless service at all times and cannot afford to experience disruptions in communications for any reasons. Staying connected at ALL times is a baseline requirement for an Emergency Responder Radio Coverage System (ERRCS).
Although redundancy is not a mandatory requirement, it is one factor to be considered to minimize single point failures in a public safety wireless communications system to provide the desired reliability. The most basic form of network redundancy is duplicating the system in its entirety, 1:1 redundancy. Full system redundancy is ideal and very effective, but in many situations, it may not be an option due to space and cost.
In this article, an alternative and cost effective method will be described – a fault tolerant system.

ABI Insight: Fronthaul Leverages Virtualization For 5G-ready V-RAN
June 21, 2017
Next-generation fronthaul is a core foundation of emerging V-RAN networks in the sense that it enables the execution of centralized access protocol functions and allows advanced dynamic capacity routing. Next-generation fronthaul is access protocol agnostic, software configurable, and supports MIMO and massive MIMO and is key to lowering equipment space and energy requirements for reduced CAPEX and OPEX.
Read this ABI paper to learn more about the drivers of fronthaul innovation and current industry trends.
ABI Insight: Virtual RAN Gets Real
May 4, 2017
The modern RAN is evolving from traditional distributed RAN (D-RAN) and centralized RAN (C-RAN) architectures to a virtual RAN (V-RAN) architecture where many of the functions of the baseband are executed in the cloud on remote telecom data centers running commercial off-the-shelf (COTS) hardware.
These changes fundamentally alter the relationship and partitioning in the basestation between the radios, basebands, data centers, and the underlying transport or fronthaul interconnecting them.
Read the ABI paper, “Virtual RAN Gets Real”, to gain a better understanding of this shift in RAN architectures, the various forms it can take and the implications for the fronthaul.
Introducing A Digital Distributed Antenna System (DAS) For Public Safety In-Building Communications
March 22, 2016
Reliable public safety radio communications are vital in today’s emergency services operation, from dispatch to mission critical situations, and from voice only capabilities to voice and data.
Public safety communications have evolved from fire call boxes, analog land mobile radios (LMR) to digital LMRs and trunked radio systems. This evolution was mainly driven by technological advancements and the need for higher reliability.
Introducing Dali Matrix™ Public Safety (PS) – the next generation all-digital Distributed Antenna System (DAS) to meet the stringent requirements of reliability and the evolving needs and requirements of public safety including broadband, LTE and FirstNet.
Reducing Total Cost of Ownership With RF ROUTER – TCO Comparison of C-RAN and RF ROUTER
April 8, 2015
A comparison of total cost of ownership (TCO) for a C-RAN and a RF Router solution has been calculated on the basis of an existing typical airport campus, applying identical business requirements for both solutions.
• Compared to a C-RAN solution under same conditions, the RF Router solution offers
typically 30…40% better TCO performance over a 3-year period. Up to 60% better
TCO can be achieved for multi-operator use cases.
• Evaluating just initial CAPEX provides an incomplete picture – it’s an OPEX game.
• Hidden costs of operational complexity are a major contributor to TCO
• C-RAN is currently mentioned only in 4G context. Nothing prevents from deploying this architecture also in 3G or 2G, but no known commercial products are available to date.
• C-RAN requires all base stations to be collocated in a single location due to mechanical coupling of baseband units. A RF Router based solution can be distributed over a wide area with up to 40 km distance between base station locations. In addition to the cost benefit, scalability and elasticity of the RF Router solution unlocks new business opportunities for operators by enabling a virtualized radio access network (v-RAN).
ABI Research: RAN Virtualization Goes Beyond C-RAN with RF Routing
April 8, 2015
Modern mobile communications networks are in the midst of profound architectural changes as they adapt to exploding volumes of dpamobile traffic as mobile network operators (MNOs) fight to maintain or minimize capital expenditure (CAPEX) and operational expenditure (OPEX) while maximizing coverage and capacity on their increasingly congested networks.
The situation is no less serious for in-building or in-venue wireless systems and perhaps even more demanding for the MNO, owner, or operator since, by many accounts, about 80% to 95% (depending on the venue and the market) of mobile traffic is consumed and / or generated indoors. Conventional in-building wireless systems use distributed antenna systems (DAS) but other technologies such as Wi-Fi and small cells are also good choices in some situations.
ABI Research believes that radio access network (RAN) virtualization is one of the top-five technology disruptors and a technique that is rapidly being brought to bear on solving these challenges. One of the first applications to feature RAN virtualization will be in-building and in-venue wireless systems, wherein a virtualized system distinguishes itself from conventional DAS, centralized or cloud RAN (C-RAN) and small cell systems by offering low total cost of ownership (TCO) and technologyagnostic RF distribution with autonomous capacity steering for higher system utilization.
RF Router – The Enabler of RAN Virtualization
March 25, 2015
Mobile data traffic is growing exponentially. This is mainly driven by video and web applications. With today’s network architecture, mobile operators are forced to increase capital (CAPEX) and operational (OPEX) to address the capacity increase. However, as networks move from being coverage-centric to capacity-centric, the increased in revenue is not keeping pace with the increased in capital expenditure.
With the forecasted future mobile network capacity requirements and the decreased revenue margin, mobile operators are looking at network sharing or virtualization as a key business model going forward to handle the increased in traffic volumes while reducing future deployment and operational cost.
In this paper, we will examine how Radio Access Network can be virtualized, and the benefits RAN virtualization brings to mobile operators and enterprise users.
