A Novel WLAN Vehicle-To-Anything (V2X) Channel Access Scheme for IEEE 802.11P-Based Next-Generation Connected Car Networks
applied sciences Article A Novel WLAN Vehicle-To-Anything (V2X) Channel Access Scheme for IEEE 802.11p-Based Next-Generation Connected Car Networks Jinsoo Ahn 1 , Young Yong Kim 1 and Ronny Yongho Kim 2,* 1 School of Electrical & Electronics Engineering, Yonsei University, Seoul 03722, Korea; [email protected] (J.A.); [email protected] (Y.Y.K.) 2 Department of Railroad Electrical and Electronic Engineering, Korea National University of Transportation, Gyeonggi 16106, Korea * Correspondence: [email protected]; Tel.: +82-31-460-0573 Received: 15 September 2018; Accepted: 29 October 2018; Published: 1 November 2018 Featured Application: V2X system for next-generation connected car networks. Abstract: To support a massive number of connected cars, a novel channel access scheme for next-generation vehicle-to-anything (V2X) systems is proposed in this paper. In the design of the proposed scheme, two essential aspects are carefully considered: backward compatibility and massive V2X support. Since IEEE 802.11p-based V2X networks are already being deployed and used for intelligent transport systems, next-generation V2X shall be designed considering IEEE 802.11p-based V2X networks to provide backward compatibility. Since all future cars are expected to be equipped with a V2X communication device, a dense V2X communication scenario will be common and massive V2X communication support will be required. In the proposed scheme, IEEE 802.11-based extension is employed to provide backward compatibility and the emerging IEEE 802.11ax standard-based orthogonal frequency-division multiple access is adopted and extended to provide massive V2X support. The proposed scheme is further extended with a dedicated V2X channel and a scheduled V2X channel access to ensure high capacity and low latency to meet the requirements of the future V2X communication systems. -

Introduction The widespread use of the Internet and especially the World Wide Web have opened up a need for high bandwidth network services that can be brought directly to subscriber's homes. These services would provide the needed bandwidth to surf the web at lightning fast speeds and allow new technologies such as video conferencing and video on demand. Currently, Digital Subscriber Line (DSL) and Cable modem technologies look to be the most cost effective and practical methods of delivering broadband network services to the masses. <-- Back to Table of Contents 2.

Topic Research Data Transmission Standards Over GSM/UMTS Networks
Slavik Bryksin [email protected] CSE237a Fall 08 Topic research Data transmission standards over GSM/UMTS networks 1. Introduction There are a lot of emerging and existing standards that are used for data transmission over cellular networks. This paper is focused on the GSM/UMTS networks technologies that are marketed as 2G through 3G, their underlying technologies and concepts (channel access methods, duplexing, coding schemes, etc), data transmission rates, benefits and limitations. The generation that preceded 2G GSM was analog, whereas all following generations are digital. Generation labeling is mostly for marketing purposes, thus some technologies that existed in 2G are carried over and labeled 3G (i.e. EDGE versions), moreover, the timeline of adoption of the protocols and their inclusion under the umbrella of a certain generation might not align with the technology inception and certification. 2. (2G) Technologies 2.1. GSM (Global System for Mobile communications) GSM data transmission protocol is circuit switched with a fixed rate of 9.6Kbps and uses TDMA (Time Division Multiple Access) to assign static downlink and uplink timeslots for data.[16] The fact that data rate is fixed leads to inefficient usage of the available bandwidth due to the bursty network traffic.[1] 2.2. GPRS (General Packet Radio Service) GPRS standard is marketed as 2.5G and was the next step after circuit switched GSM standards. It is packet switched, which implies better bandwidth utilization, however packetization of data incurs the cost of extra information included in the packet, and the overhead of negotiation of transmission with the base station. -

Using the BCD996T with a GPS
Precautions Before you use this scanner, please read and observe the following. IMPORTANT! This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them. The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. Your local law enforcement officials should be able to provide you with information regarding the laws in your community. Changes or modifications to this product not expressly approved by Uniden, or operation of this product in any way other than as detailed by this Operating Guide, could void your authority to operate this product. EARPHONE WARNING! Be sure to use only a monaural earphone or 32 Ω stereo headset. Use of an incorrect earphone or stereo headset might be potentially hazardous to your hearing. The output of the phone jack is monaural, but you will hear it in both headphones of a stereo headset. Set the volume to a comfortable audio level coming from the speaker before plugging in the monaural earphone or a stereo headset of the proper impedance (32 Ω). Otherwise, you might experience some discomfort or possible hearing damage if the volume suddenly becomes too loud because of the volume control or squelch control setting. This might be particularly true of the type of earphone that is placed in the ear canal. -
