In small and micro branches, a single AP is often capable of meeting network requirements. Network uplinks are usually Internet lines provided by carriers and a Point-to-Point Protocol over Ethernet (PPPoE) account needs to be configured for Internet access in dial-up mode. Traditionally, O&M personnel can log in to an AP from a laptop or PC and perform account and service configurations on the web system. However, if APs need to be deployed in a large number of stores and the construction and deployment personnel do not possess necessary network O&M skills or tools, professional deployment personnel are required. This increases the overall deployment time and costs. As shown in Figure 7.49, after the mobile O&M app connects to an AP and simple configurations are performed, the AP is ready for deployment. This simplified process dramatically improves deployment efficiency and reduces associated costs, while also requiring minimal deployment skills. Thanks to the mobile O&M app, even installation personnel can successfully complete deployment and bring APs online.
IPTV and WiMAX
Published in Amitabh Kumar, Mobile Broadcasting with WiMAX: Principles, Technology, and Applications, 2014
The points T, V, and A10 are denominations of reference points, which are further specified in terms of protocols and standards. BRAS is the broadband remote access server. In DSL implementations, the protocols used are layer 2 point-to-point protocols (PPP) over Ethernet (PPPoE) or IP over Ethernet. PPP is the protocol most commonly used in RAS dial up applications. In case of 802.16-2004 implementations of WiMAX the wireline DSL network can be replaced by a Fixed WiMAX network by simply using Ethernet bridging when IP over Ethernet is used as in this case the higher layer protocols are not impacted. In case PPP is being used, then the PPP packets have to be encapsulated into PPPoE frames and then carried over Ethernet by bridging, making the Fixed WiMAX link transparent.
Open-IPTV Services and Architectures

For accessing nomadic services from any place we mainly have two ways: All Based Home Network: In this scenario, both service and content could be provided by the home network. So, the nomadic network uses specific software to connect to the home network and to forward the service. This connection establishment has two phases. In the first phase, the client connects either to one’s ordinary Internet Provider (from home) or to the nomadic network using any dial-in point-to-point connection like PPPoE (PPP over Ethernet). Then, the PPPoE makes a connection to a LAN, and provides authentication, authorization, and accountability issues for this client from one’s home network. After the user passed this verification phase over multiple Internet providers and had the settings to specific service, he could make a VPN (Virtual Private Network) connection using for example, PPTP (Point-to-Point Tunneling Protocol). This will encrypt the traffic by passing it through a “tunnel.” This tunnel is secure so that other people cannot intercept the traffic and read as it passes across the Internet or over different wireless connections.Service-Based Home Network: Service is provided by the home network while content is provided by the visited network or nomadic network. In this scenario, the client has to pass a secure authentication and authorization connection with one’s home service providers. Then inter policy between providers will give the content requested from the very near point to the visited network.
Automation and redistribution of work: the impact of social distancing on live TV production

A transition to incorporating remote work into the workflow of the production also required training and supporting the remote participants. This support included giving instructions on how to set up lighting, place microphones, and use cameras at home, as well as how to best operate the equipment at hand. These instructions varied according to the setup and expected level of quality of the production. In one case for a big sports event production, they put together standardized kits of equipment, including a two-camera setup and a light setup, to be assembled at the remote location: For the NFL draft earlier this year, they did the entire thing as a remote production. In fact, it was run out of the director’s garage. But they knew who they were going to be talking to way ahead of time. They knew they were going to have an audience of 30 or 40 million people, so they built standardized kits that they could send to every single person they would interview, including a light setup and a two-camera setup, that they could just put down and turn on, and then the people at the NFL could remotely [log] in to it and do all the settings changes just to make sure that it’s okay. That way, they can control the quality of the interview. That is what we’re doing now too. We give them [interviewees] a small PC and a PPPoE [Point-to-Point Protocol over Ethernet] camera and a light ring, so [they] have the same setup. When I do an interview with them, I can log in to that computer remotely, adjust the camera, adjust lighting and all of that stuff, and set everything up so they don’t have to do anything except sit there and talk.
