The photo above shows the WiMAX radio deployed in an enclosure. Note from left to right: a) copper grounding cable on the inside of the enclosure b) Ethernet connection to the data source c) Heliax “pigtail” to the antenna (Heliax is a heavy duty, lightning resistant cable) d) 110v power via an APC UPS (note … Read more
At the core of WiMAX is the WiMAX radio. A radio contains both a transmitter (sends) and a receiver (receives). It generates electrical oscillations at a frequency known as the carrier frequency (in WiMAX that is usually between 2 and 11 GHz). A radio might be thought of as a networking device similar to a … Read more
Point-to-Point(P2P) Point to point is used where there are two points of interest: one sender and one receiver. This is also a scenario for backhaul or the transport from the data source (data center, co-lo facility, fiber POP, Central Office, etc) to the subscriber or for a point for distribution using point to multipoint architecture. … Read more
Implementation Margin in LTE Implementation margin is used to include non-ideal receiver effects such as channel estimation errors, tracking errors, quantization errors, and phase noise. This implementation margin or sensitivity degradation can be used to apply some margin to the link budget to account for devices from other vendors that may have larger tolerances from … Read more

The main services provided by the Packet Data Convergence Protocol (PDCP) are: IP header compression and decompression … Read more
One of the most often heard descriptions of WiMAX in the press is that it is “Wi-Fi on steroids”. In truth, it is considerably more than that. Not only does WiMAX offer exponentially greater range and throughput than Wi-Fi (technically speaking 802.11b, although new variants of 802.11 offer substantial improvements over the “b” variant of … Read more
Mobile WiMAX allows any telecommunications to go mobile. Mobile WiMAX takes the fixed wireless application a step furher and enables cell phone-like applications on a much larger scale. For example, mobile WiMAX enables streaming video to be broadcast from a speeding police or other emergency vehicle at over 70 MPH. It potentially replaces cell phones … Read more
