Used Alcatel Evolium telecoms equipment
EvoliumTM Multistandard Base Stations for GSM networks have been designed to enable you to deploy and expand a network more quickly and easily. With EvoliumTM Multistandard BTSs you’ll save capital expenditures and ongoing costs. What’s more, you’ll be able to increase revenue flows and customer satisfaction through new and enhanced services, like GPRS, EDGE and UMTS.
The EvoliumTM family of Base Stations has been designed to offer the different configurations that meet all your operational and field constraints. Whether you want small or large capacity, you’ll find the right size to operate indoors or outdoors. Just select the optimal size from among the wide range of configuration options:
- Medi cabinet for concentrated power a compact, indoor unit,
- Mini cabinet for tight indoor installations or small base stations,
- Outdoor cabinet for operations in environments, with simple expandability through an additional cabinet.
The low power consumption of all EvoliumTM Multistandard Base Stations significantly cuts your BSS operating costs (only 1, 730W for the indoor version with 3x4 TRXs in a sectored configuration). The reduced noise emission allows installations even in environmentally sensitive areas.
Modular and scalable, EvoliumTM Base Stations enable you to adapt the capacity of each cell to your precise traffic requirements. High performance, large capacity and easy reconfigurability mean you’ll need fewer total units. 4 basic modules are able to offer a large variety of configurations.
The EvoliumTM family of Multistandard Base Stations offers unmatched and field-proven radio performance in a range of compact units designed to fit your requirements today and in the future:
- 35W/45W output power for all frequency ranges as a standard feature
- Receiver sensitivity surpassing GSM standards (-111dBm)
- 60W high power transceiver for GSM 1800
- Range Extension Kit for enhanced coverage in rural areas for GSM 900
- Dynamic power control for discontinuous transmission and reception
- Synthesized Frequency Hopping as a standard feature
- Optimized A-bis interface with submultiplexing schemes to handle more stations or transceivers in multidrop configurations
- Selectable ciphering algorithms.
Compact and power-efficient, EvoliumTM Base Stations help cut site acquisition and installation costs:
- Up to 12 TRXs per cabinet,
- Omnidirectional or sectored configurations
- 43 liters per TRX
- 0.25 sq.m. footprint for indoor cabinets
- Optional integrated transmission equipment, such as HDSL or microwave
Thanks to the modular design, all EvoliumTM Multistandard Base Stations are ready to deliver advanced features to your network, such as:
- Multiple or single-antenna operation
- Dual Rate, Enhanced Full Rate and Adaptive Multi Rate voice processing
- Ability to build a multiband site in one cabinet. This means you can run GSM 900/1800, dualband operations from a single, existing rack
- Supports multiband cell configurations
- Introduce GPRS with no hardware changes thanks to easy software download
- All TRXs are compatible GSM/GPRS/EDGE. An easy download is required
Equipment and radio network availability are reinforced thanks to new protection benefits:
- Fault-tolerant units with built-in duplication and automatic recovery features
- Progressive smart power down increases back-up battery life cycle by shutting down some transceivers in case of AC power failure
- Bridge over on the A-bis interface to automatically direct traffic to the next station in a multidrop configuration in case of failure
- Supports two software versions simultaneously so new versions can be downloaded quickly with no disruption to service
The entire family of indoor and outdoor EvoliumTM Multistandard Base Stations is built around just four types of modules. So your maintenance specialists can get up to speed faster and there’s no need to carry a large spare parts inventory. Smart facilities are integrated for easier maintenance:
- Automatic test routines constantly monitor operations while remote analyses provide network supervisors with complete, up-to-date BTS radio configuration
- Back-up battery to prevent main power failure
