Hybrid Beam forming performance analysis–OFDM Massive MIMO

OFDM multi-transporter adjustment is expected to be the facultative innovation for 4G remote frameworks. One of the choices that make OFDM the main option for 4G is its MIMO similarity, because of MIMO envelops a horribly critical capability of improving remote frameworks for limit, information rate, and scope angles. In this paper, the difficulties of MIMO OFDM estimations square measure tended to and request of transmittal control administration by client is examined. Downlink power and transmission control is restricting component in the execution of MIMO OFDMA framework. A sufficient power prevailing component upheld shut circle of base station is reply to the present disadvantage

An integrated AP for seamless interworking of existing WMAN and WLAN standards

Broadband Fixed Wireless Access (BFWA) systems represent a potential technological foundation for the Fourth Generation of Wireless Mobile Communication Systems (4G) as they can replace wired broadband and, with sufficient widespreading deployment, can significantly cut into the usage of cellular networks in many areas. In this context, the seamless interworking of Wireless Metropolitan Area Network (WMAN) and Wireless Local Area Network (WLAN) technologies is an efficient solution to provide the indoor extension of BFWA systems coverage, which would largely contribute to their success and penetration in the market. In this paper, we introduce a novel Access Point (AP), called WMAN/WLAN AP (WWAP), which essentially integrates in a compact device a WMAN Subscriber Station (SS) and a WLAN AP in order to extend the WMAN coverage in-house and to guarantee the end-to-end Quality of Service (QoS). Besides the technical features, the market trends and the usage scenarios where the WWAP might be a cost-effective and a very efficient solution are outlined. Finally, simulation results are carried out in order to demonstrate the effectiveness of the proposed AP
