Duplexing Techniques TDD & FDD in Wireless Networks
TDD (Time Division Duplexing), FDD (Frequency Division Duplexing) Duplexing refers to the way downlink and uplink data is arranged in a two-way wireless transmission. The downlink carries information from a Base Station (BS) to Subscriber Stations (SSs, which could be a handset or a PC). Downlink is also known Continue Reading
Non 3GPP Wireless Access Technologies: WiFi & WiMAX
Trusted & Un-trusted Non-3GPP Access Technologies (e.g. WiMAX & WiFi) As you (should really) know that SAE (System Architecture Evolution), also know as EPC (Evolved Packet core), the common core network defined in 3GPP Rel 8, supports all types of access networks, be it radio or fixed line, 3GPP such Continue Reading
