The HiperMAX-micro is the outdoor version of HiperMAX. It is a highly upgradeable base station, typically with a roof mounted radio system and antennae.
Note:
Design and provision of the infrastructure is the responsibility of the
Network Provider.
The HiperMAX-micro is designed to be located on building roof tops providing point to multi-point WiMAX coverage from an all outdoor base station over micro-cellular ranges to various CPE types.
Note, the term “micro” in the title denotes the normal deployment type which this particular packaging of HiperMAX suits, ie. Low sited, low sector count base station deployments.
The HiperMAX-micro product is a highly upgradeable micro-base station, utilizing a software defined radio (SDR) to enable complete upgradeability of the MAC and PHY. The HiperMAX-micro is typically designed for rooftop or pole mounted deployment. The use of separate antennas enables transmit and receive gain diversity techniques to be utilized, which increases link budget capability. The HiperMAX-micro supports both 802.16-2004 “Fixed WiMAX” system profiles for fixed and nomadic applications, as well as providing a platform for future software upgrades to support WiMAX 802.16e-2005 “Mobile WiMAX” system profiles for portable and mobile applications.
A typical HiperMAX-micro base station configuration consists of the following components:
1x SDR-micro (including Software Defined Radio, PSUs for SDR + SCRTs plus a GPS receiver [where required])
2x Single Channel RF Transceiver (SCRT)
2x antenna 3.5GHz or 4.9GHz (attaching to the front of the SCRT)
Optionally 2x Independently mounted antennas (short feeder feeder length 1-2 metres).
The HiperMAX-micro base station consists of a Software Defined Radio (SDR-micro) which includes the baseband and optional GPS module within a single environmentally protected enclosure. The SDR-micro is connected to two Single Channel Radio Transceivers (SCRT).
The baseband sub-system, used within the HiperMAX-micro base station, uses the same technology as the baseband blade fitted within the HiperMAX base station.
The HiperMAX-micro modem’s architecture is based on configurable elements, allowing implementation of a software defined radio, which ensures changes in specification can be adopted without the need to change the basic hardware construction. Using the approach based on configurable elements, the HiperMAX-micro base station can be upgraded from the 802.16-2004 OFDM “Fixed WiMAX” system profile to the 802.16e-2005 OFDMA “Mobile WiMAX” system profile through the simple process of upgrading the system software. The PHY processing is implemented using picoChip™ technology, and the MAC is implemented within two PowerPC processors.
The GPS receiver is a factory fit option and is part of the SDR-micro It is used to synchronize Tx & Rx timing between base stations in order to avoid unwanted “hub-to-hub” interference seen with TDD systems.
HiperMAX-micro is equipped with the same remote radio SCRT units as HiperMAX. See Single Channel Radio Receiver
