Description

WiMAX makes new performance levels and new provider economics possible, transforming the business case for deployment of broadband wireless access. It creates the environment for high quality, multi-megabit services to be delivered to end users more cost effectively by creating a global marketplace and a framework for inspiring innovation.The high bandwidth of WiMAX delivers real-time applications much faster than other technologies do today, including:

• Interactive gaming

• Video conferencing

• Virtual Environments

• Music

• Streaming video: movies, TV, videos

Why

A service provider, network operator or an enterprise, WiMAX enables you to deliver the differentiated high-speed and high-bandwidth data services your customer’s value. Fixed WiMAX is ideally suited for:

• Broadband access to underserved areas, and extending DSL/cable modem services to rural areas

• Replacing more expensive means of Broadband access such as DSL, cable modem services, and satellite TV.

• Backhauling traffic for wireless service providers or cable operators at a reduced cost.

• Interconnecting and backhauling WiFi hot zones built on Wireless Mesh Network solution(for instance Nortel).

• Enabling ISPs, cable and satellite operators to deliver existing content through a new channel

• Providing robust, secure bandwidth for data traffic and communications for financial and educational institutions, municipalities and in-the-field military or public safety institutions.

How

WiMAX delivers not just significant improvements in speed, throughput and capacity to home and small business users, but also enables portable and mobile services to laptops and handheld devices.Base Transceiver Station (BTS) can refer any of the wireless communication standards, it is generally and commonly associated with mobile communication technologies like GSM and CDMA. In this regard, a BTS forms part of the Base Station Subsystem (BSS) developments for system management. It may also have equipments for encrypting and decrypting communications, spectrum filtering tools (band pass filters) etc.Antennas may also be considered as components of BTS in general sense as they facilitate the functioning of BTS. Typically a BTS will have several transceivers (TRXs) which allow it to serve several different frequencies and different sectors of the cell.A BTS is controlled by a parent Base Station Controller via the Base station Control Function (BCF).

  • The BCF is implemented as a discrete unit or even incorporated in a TRX in compact base stations.
  • The BCF provides an Operations and Maintenance (O&M) connection to the Network management system (NMS),
  • It manages operational states of each TRX, as well as software handling and alarm collection.
  • The basic structure and functions of the BTS remains the same regardless of the wireless technologies.

The appeal of WiMAX systems lies in the fact that they can be applied to a host of applications offered by a range of different providers –— including cellular operators, wireline carriers, cable operators, MSOs and new entrants.

Future Trends

The WiMAX market has drastically shifted focus from 802.16d to 802.16e, as the coming wave of mobile WiMAX base stations, CPE, and mobile devices will fuel WiMAX’s growth. While examining major drivers and barriers for WiMAX and compares it to 3G and other 4G technologies. 802.16m – or WiMAX 2.0 – is considered in detail, as is the WiMAX patent landscape.The report contains forecast sets for 802.16-2004 and 802.16e-2005, and includes subscribers, ARPU, and revenue by region, and CPE and base station shipments, ASP, and revenue by various segmentations. Detailed segmentation is provided for mobile WiMAX devices, including external adapters, miniCards inside laptops, handsets, consumer electronics, PNDs, UMPCs, and mobile Internet devices.
