LTE Evolution Platform


IPWireless' LTE Evolution Platform  enables mobile operators, rural carriers and government agencies to build flexible, low-cost and high performance broadband wireless networks whether  for a multi agency government network (MAGNet) or commercial operator network. The scalable IPWireless Radio Access Network (RAN) architecture can be deployed for small rural community to high capacity city and nationwide networks. The built-in quality of service allows the operator to offer voice and data services and subscriber based Service Level Agreement. IPWireless RAN interfaces with standard IP based infrastructure, greatly reducing the deployment cost and affording the operators a wide selection of IP core network options. The platform is software upgradeable to support a seamless migration to 4G Long Term Evolution (LTE) when the customer is ready to upgrade their network.

IPWireless Node B Base Station

IPWireless V5 NodeB ™ features flexible base station architecture for current and future 3GPP wireless standards. It consists of Software Defined Radio (SDR) baseband processing supporting 3GPP TD-CDMA today and provides a seamless upgrade path to LTE in the future.

The IPWireless V5 Node B is a modular architecture consisting of one digital shelf and multiple radio shelves for multiple sectors of cellular deployment.

The IPWireless V5 Node B digital shelf is a rack based system consisting of one control card, up to three sector cards and a Universal Gateway Card (UGC). The Universal Gateway Card supports a distributed flat IP architecture, greatly reducing the cost of investment for initial network rollout. The IPWireless V5 Node B Radio shelf can be located close to the antenna or up to 500 meters from the digital shelf using a CPRI fiber interface, eliminating the RF cable loss. Individual sector cards and radio shelves are field replaceable without affecting other sectors in the Node B.

Key Features

• Modular architecture for 1 to 3 sectors deployment
• Coverage from dense high capacity network to extended range up to 29 km
• Multiple chip rate / bandwidth support via software configuration
• Advanced MIMO and interference mitigation
• Future proof software upgradable digital baseband
• Remote configuration management and performance reporting
• 'Always-on' Internet access

Integrated Network Controller (INC)

The IPWireless Integrated Network Controller (INC) is a high performance broadband wireless network controller supporting the international 3GPP TD-CDMA system. The INC integrates the GGSN, SGSN and RNC functions in a compact rack mount hardware, greatly reducing the cost of deploying a broadband wireless network. The INC aggregates Radio Access Network (RAN) data and management traffic from several Node Bs towards a standard IP core network.

 

Protocols

On the gateway network side of the INC, standard Internet Protocols are used, allowing the connectivity of the INC to an IP router. The INC aggregates all user traffic to an IP router and supports traffic prioritization to and from the core network. The INC communicates with RADIUS servers for Authentication, Authorization and Accounting (AAA) via standard RADIUS protocol. On the Radio Access Network side of the INC, 3GPP Iub protocols are used to communicate with the Node B.

INC Platform

The INC is based on a standard NEBS compliant 19" compact PCI rack and built on a fault tolerant operating system. Interface standards supported include Ethernet and E1.

IPWireless Element Management System (EMS)

The IPWireless Element Management System (EMS) provides configuration management, performance monitoring and alarm/event reporting for the IPWireless TD-CDMA network elements. IPWireless EMS software runs on industry standards servers and communicates with INC and Node B via SNMPv3. EMS clients connect to the EMSserver via standard web browser making remote management of the network possible.

 

Features

The IPWireless EMS supports configuration management, performance management and fault management of the network elements in the operator's TD-CDMA network. The EMS software uses SNMP to communicate with the INC and Node B.

The EMS servers are configured in pairs to provide redundancy load balancing. Each network element is assigned a primary and a secondary EMS server. Network performance logs can be stored on the local EMS server or send to a remote dedicated server for data analysis.

The IPWireless EMS client is Java based, allowing an operator to manage the network from practically any PC equipped with Microsoft Internet Explorer®.

EMS Platform

The IPWireless EMS runs on a Sun™ server. The operator can choose Sun
server platforms to match with the network size and data logging requirements.
