WiMAX Remote Radio Heads

Key benefits compared to ground basestation architecture:

RRH applications, features and benefits

A standard RRH implementation involves a close cooperation between the customer and the AxisNT engineering team, to perform interoperability on the OBSAI and/or CPRI digital interface implementation. Products are available with a variety of interface connector options, with a single or dual fibre optic interface for up to 10km of FO cables, a choice of compact and lightweight packaging, and may have an optional customised solar shield. They are optimised for low power consumption and feature a wide input voltage range to provide flexibility in site installation. A built in handle and a variety of mounting brackets allow ease of installation. Additionally AxisNT will customise its RRH for the specific requirements of OEM customers, in respect of connectors, packaging and labels.

Product integration and branding

It is important to note that AxisNT technology can deliver 2 x 8W performance whilst still meeting the very demanding mandatory spectral requirements. This enables Axis RRHs to deliver a unique level of high power balanced link performance at significantly reduced CAPEX and OPEX when compared to conventional systems.

Due to the use of our patented transceiver technology, Axis RRH exhibit excellent uplink and downlink performance to give customers the coverage and capacity edge. Typical Axis RRH sensitivity is better than -98dBm single channel and better than -100dBm for 2 channel MIMO. The downlink transmit powers of 2 x 8W (MIMO) in a RRH configuration (typically saving 3dB cable losses) are equivalent to a conventional BTS with 36W output. As a result, Axis convection cooled RRHs reduce the running costs and power consumption of a wireless network by 90%.

The AxisNT family of Remote Radio Heads (RRH) is available immediately for OEM deployment in WiMAX networks worldwide. Versions covering UMTS/LTE applications will be available in early 2009.
