Salient Future for Mobile WiMAX WiMAX is a wireless broadband solution that offers a rich set of features with a lot of flexibility in terms of deployment options and potential service offerings. Some of the more salient features that deserve highlighting are as follows: OFDM-based physical layer: The WiMAX physical layer (PHY) is based on … Read more
Mobile IP Procedures – Agent Discovery, Registration, Tunneling in Wimax Mobile IP Procedures Having Three Flow. Agent Discovery Registration Tunneling Agent Discovery Agent Discovery is the method by which a mobile node determines whether it is currently connected to its home network or to a foreign network, and by which a mobile node can detect … Read more
Angular Spread and Coherence Distance calculation for Wimax Calculation Angular Spread and Coherence Distance is very easy let’s see. So far, we have focused on how the channel response varies over time and how to quantify its delay and correlation properties. However, channels also vary over space. We do not attempt to rigorously treat all … Read more
LTE – eNodeB, MME and SAE Function in Short Here I write in short about eNodeB functions, Mobile Management Entity (MME) functions and System Architecture Evolution (SAE) functions. LTE (Long-Term Evolution) represents a significant advancement in wireless communication technology, with key components such as the eNodeB (evolved NodeB), MME (Mobility Management Entity), and SAE (System … Read more
In the context of WiMAX (Worldwide Interoperability for Microwave Access), NAP and NSP are important entities that play crucial roles in providing wireless broadband services. What is NAP & NSP in Wimax ? How it Works ? Let’s delve into what NAP and NSP stand for, and how they work together within the WiMAX ecosystem. … Read more
The procedures for the Non Access Stratum, especially power management procedures are substantially similar to UMTS. Main change is that the UMTS EPS allows concatenation certain procedures to allow faster creation of connection and media. Create MME UE context, when the UE is on and attaches to the network. Assign a unique ID called SAE … Read more
If a mobile device moves to a new network and keeps the same IP address, the address will not reflect its new location therefore routers will be unable to route datagram to it correctly (or at all). Alternatively, if a mobile device moves to a new network and gets allocated a new address, already established … Read more
The challenge to broadband wireless comes from the scarcity of radio-spectrum resources. Regulatory bodies around the world have allocated only a limited amount of spectrum for commercial use. The need to accommodate an ever-increasing number of users and offering bandwidth-rich applications using a limited spectrum challenges the system designer to continuously search for solutions that … Read more
