Axis Network Technology has launched a range of multi-carrier remote radio heads (RRH) offering multi-standard operation across both 3.5G HSPA+ networks and the planned 3GPP LTE networks.

The RRHs provide 2 x 25W of multi-carrier RF power using AxisIPR amplifier technology within 406mm x 293mm x 153mm.

They operate over the 1.85GHz -2.62GHz E-UTRA frequency bands, for either TDD or FDD modulation formats, with models for E-UTRA bands 38 and 40 available for immediate OEM deployment.

The units are based on the same design platform as Axis’s WiMax RRH.

They can be customised to meet the specific interface and packaging requirements of the OEM, including the option of OBSAI RP3-01 or CPRI digital baseband interfaces or custom OEM fibre interfaces.

Designing base stations using a distributed RRH approach minimises the environmental impact of the base station and reduces both CAPEX and OPEX of the overall system.

Using RRHs also gives maximum scalability and flexibility for LTE network deployments.

The RRHs can operate with two-channel MIMO for HSPA+/LTE, and they are also capable of four-channel MIMO operation if two daisy-chained units are used.

They feature field programmable LTE channel bandwidths from 1.4MHz to 20MHz, and control and alarm management with AxisOS OandM.

Axis multi-carrier RRHs feature: automatic calibration for transmit, receive and PA bias control loops; OBSAI RP3-01 and CPRI V2 digital baseband interfaces with one or two optical connectors; high reliability including an advanced failure mode prediction capability, as well as inherent fibre and RF redundancy.

Carriers can be placed anywhere within the full 20MHz bandwidth supported by the Axis RRH, including non-contiguous carrier placement.

Support for adaptive antenna systems (AAS) and AISG v2.0 antenna control is provided, and the unit features a compact, lightweight modular design in a die-cast enclosure, with solar shield for outdoor use.
