This paper contains a comparison of some of the wireless standards authored by the Institute of Electrical and Electronics Engineers (IEEE) [1]. It explain some of the differences and similarities between the IEEE 802.11, 802.15.1, 802.15.4 and 802.15.6 wireless standards with an emphasis on the physical layer.
IEEE 802.15 is a working group of the Institute of Electrical and Electronics Engineers (IEEE) IEEE 802 standards committee which specifies Wireless Specialty Networks (WSN) standards. The working group was formerly known as Working Group for Wireless Personal Area Networks.
11 lip 2011 · Considering the huge quantity of devices, high transmit power, and large coverage range, IEEE 802.11 [5] devices interfere with IEEE 802.15.4 most seriously. In this paper, we survey the studies on wireless coexistence between IEEE 802.11- and IEEE 802.15.4-based networks.
IEEE 802.11 ( or WiFi) interfaces described as high power consumers, while, IEEE 802.15.4 modules described as ultra low power consumers.
Produkowane masowo urządzenia 802.11b obsługują przepływność 11 Mb/s, ale możne zostać ona obniżona do 5,5 Mb/s, 2 Mb/s oraz 1 Mb/s. Spektrum 802.11b jest podzielone na maksymalnie 14 kanałów o szerokości 22 MHz każdy. Kolejne kanały zachodzą na siebie nawzajem – tylko trzy kanały nie pokrywają się.
2010. TLDR. Simulations reveal that Minimum Shift Keying is best suited for all types of devices in 802.15.4 for wireless sensor networks (WSNs) if the network output load is to be maximized as more is the output load, more will be the net throughput. Expand.
In the case of 802.11 and 802.15.4, both technologies have versions that use the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, which can result in CTI between the two protocols. INET has support for simulating CTI between any of its wireless protocol models, including 802.11 and 802.15.4.
