Wimax Business requirement by Point-To-Point or Point-to-Multipoint

Applications using a fixed wireless solution can be classified as point-to-point or point-to-multipoint. Point-to-point applications include interbuilding connectivity within a campus and microwave backhaul. Point-to-multipoint applications include broadband for residential,…

Important OFDM characters for Wimax

Here I list out some important OFDM characters for Wimax. Let’s check it in detail. OFDM Pros and Cons: OFDM enjoys several advantages over other solutions for high-speed transmission. Reduced…

Which OFDM Parameters Used in WiMAX

The  fixed and mobile versions of WiMAX have slightly different implementations of the OFDM physical layer. Fixed WiMAX, which is based on IEEE 802.16-2004, uses a 256 FFT-based OFDM physical…

Interference Limited MIMO Systems for Wimax

The third assumption—that the background noise is Gaussian and uncorrelated with the transmissions—is especially suspect in a cellular MIMO system. All well-designed cellular systems are by nature interference limited: If they…

How Open-Loop Transmit Diversity in Wimax?

Transmit spatial diversity is a newer phenomenon than receive diversity and has become widely implemented only in the early 2000s. Because the signals sent from different transmit antennas interfere with…

Spatial multiplexing and Receive Diversity in Wimax

Spatial multiplexing WiMAX also supports spatial multiplexing, where multiple independent streams are transmitted across multiple antennas. If the receiver also has multiple antennas, the streams can be separated out using…

QoS Mechanisms in Packet Networks

There are Three Types of QoS Mechanisms in Packet Networks. Control Plane Mechanisms Data Plane Mechanisms Its Tradeoffs Control Plane Mechanisms Such mechanisms include QoS policy management, signaling, and admission…

Authentication and Access Control in Wimax

Access control is the security mechanism to ensure that only valid users are allowed access to the network. In the most general terms, an access control system has three elements:…
