This whitepaper describes the seven modes of MIMO defined in the 3GPP LTE. Particular aatention is given to the applicability of these modes in different radio channels.
WiMAX is a wireless access technology for building networks with large coverage areas and high data rates, so-called Metropolitan Area Networks (MANs).
This white paper presents an overview on how to deliver PSTN quality VoIP services over WiMAX networks.
This whitepaper provides the results of independent performance tests of Bridgewater’s control plane solution including the Home Subscriber Server and Policy Controller and the Cisco ASR 5000 mobil
Higher capacities and lower latencies are a must for LTE backhaul.
In an industry that makes a habit out of squabbling over technology standards, the move to 4G wireless networks is no different.
Security is a fundamental building block of wireless telecommunications systems. It is also a process – new threats are discovered over time, forcing communication systems to evolve.
This paper discusses the improvements that uplink MIMO brings to Mobile WiMAX network deployments and introduces a new technique based on uplink MIMO, tile switched diversity (TSD).
The 3GPP LTE system has been designed to offer significantly higher data rates, higher system throughput, and lower latency for delay critical services.
Femtocells are small, user-installed base stations that enhance coverage for in-building cellular services.
