Traditionally, microwave
radios have been designed to operate at very specific capacities and
frequencies, and the process of changing these two parameters has
involved high switching costs requiring additional investment. With the
deployment of next-generation networks such as 3G, UMTS and WiMAX on the
increase, it's imperative that these networks are based on equipment
versatile enough to handle not only today's communication technology,
but also equipment that is future-proof. Ready for what you need - when
you need it. Can this be done without breaking the budget - today, and
without major and expensive replacements in the future?
The answer is yes! By using Nera's new Evolution Series.
LOWER
COSTS - NOW AND IN THE FUTURE
Significant saving in network deployment and operation are achieved
by the use of one common hardware platform across the whole network.
Furthermore, planning and installation activities are simplified due to
mainstream mechanical design and configuration, and costs for inventory
and maintenance are minimized.
Increased reliability - the total life-cycle cost for the Evolution
series is minimized by use of high-level integration and a simplified
architecture; as a result, high Mean Time Between Failure (MTBF) as well
as reduction in potential revenue loss due to outages and lower OPEX can
be achieved.
Increased flexibility - Transmission is scalable in multiple directions
from a single radio node which allows the operator to explore various
network topologies such as ring, chain/star and mesh - all with the
same, universal type of equipment. User selectable modulation rates from
QPSK to 128 state / multi-dimensional and provides the operator with a
choice between system gain and lower licensing fees. Seamless
integration between PDH and SDH enables site selectable configuration
from 4E1/T1 to 3+1 STM-1/ OC-3 - you pay as you grow.
FREEDOM - SOFTWARE DEFINED SCALABILITY
The new Evolution Series offers operators the freedom to change
established backhaul bandwidth/capacity, quickly and easily under
software control. No physical replacements are necessary. Upgrades can
be done instantly, and remotely - you can redefine the configuration by
simply upgrading the licence by means of software - you pay as you grow.
These features allow the operator to minimise licencing cost and the
resources spent on ensuring mobile network performance. They also enable
the operator to focus more on business issues such as attracting
additional customers and revenue rather than operational barriers to
growth.
CONTROL - OPTIMUM MONITORING
Configure. Manage. Monitor. NetMaster is the network management system
that keeps it all at your fingertips. This powerful multiplatform
application features an intuitive and user friendly GUI. It provides
automatic network discovery and configuration, fault management with
alarm correlation, trouble ticketing and performance management; all by
the same licence principle as the rest of the Evolution Series - you pay
as you grow.
The solution for cost-effective deployment of low and medium capacity
transmission networking. The CompactLink is a fully featured, microwave
radio system for the global telecommunications market. The CompactLink
operates in the frequency band 13, 15, 18, 23 and 38 GHz, and with data
rates of 2, 4, 8, 16 E1 or E3+E1. ANSI versions operate with data rates of
2, 4, 8, 16 DS1 or DS3+DS. It is designed for transmission of voice, data
and video traffic. Standardized data rates (E1/T1) and frequency bands are
controlled by international organizations (FCC, ITU-R, ITU-T, ETSI). The
IDU is frequency independent and fits into an ETSI rack or a 19" rack.
Alternatively, it can be used as a stand-alone unit. Both ETSI and ANSI
transmission capacity requirements are supported.
- ETSI: 2E1, 4E1, 8E1, 16E1 and E3+E1.
- ANSI: 2DS1, 4DS1, 8DS1, 16DS1 and DS3+DS1.
In the unprotected configuration, one 1RU IDU is
required and in the HSB configuration, one 2RU IDU is required. The Nera
CompactLink ODU integrates transceiver and branching in one unit. For the
HSB configuration, an outdoor RF hybrid is included to combine the two
ODUs. The Nera CompactLink ODU is capacity independent, frequency
synthesized and has adjustable T/R spacing. For unprotected
configurations, the IDU and ODU are connected with a single coaxial cable
(maximum 300 m). In the HSB configuration, the IDU and ODUs are connected
via two separate coaxial cables. With the built-in SNMP agent, the Nera
CompactLink - PDH Microwave Radio is capable of functioning as a Network
Element (NE) in a managed transmission network. Management and supervision
of the Nera CompactLink can be performed in various ways, from simple
alarm monitoring to standardized management via SNMP. For network
management and operation, the Nera Element vieW - Network Management
System (NEW NMS) can be delivered. An integrated antenna/mount solution
can be delivered with antennas having diameters of 0.3 m, 0.6 m or 1.2 m.
When system performance requires higher antenna gain, independently
mounted, larger antennas can be used.
