A Case Study: Broadband Over Powerline for Rural Area Deployment in Sarawak

Broadband over powerline (BPL) is a technology that allows connectivity to internet connection riding via the low tension (LT) power line communication (PLC). A hybrid BPL technology was proposed to the rural area of Sarawak as an alternative option to expand the internet connection without the need to reform a new pathway for internet connectivity. The data signal is transmitted via a communication tower to the access point(s) that is mounted on an electricity pole that provides a low voltage (LV) line. There are three types of custom-designed equipment that has been integrated into the hybrid BPL: the Head End (HE), the Time Division Repeater (TDR) and the Customer Premise Equipment (CPE). Two longhouses at the Bawang Assan, Sarawak settlement has been chosen to initiate the pilot project that required the cooperation of the technology provider, power producer, and the internet service provider. This paper presents a proof of concept (POC) on the deployment, advantages, and limitations for the BPL in a rural setting.

Enabling Sector Scheduling for 5G-CPE Dense Networks

5G customer premise equipment (5G-CPE) is an IoT gateway technology that integrates 5G and Wi-Fi and therefore can provide Wi-Fi connection for IoT devices and meanwhile benefit from the advantages of 5G. With the increasing number of IoT devices, transmission collisions and hidden/exposed terminal problems on the Wi-Fi connection side become more and more serious. Conventional mechanisms cannot solve these problems well. In this paper, we propose a Wi-Fi sector (Wi-FiS) design, which is compatible with Wi-Fi, to solve them fundamentally. Wi-FiS divides the whole coverage area of Wi-Fi into multiple sectors and utilizes beamforming technology and sector-based scheduling to improve system performance of Wi-Fi dense networks. For a single-cell network, Wi-FiS differentiates uplink and downlink operations and totally excludes collision in downlink. For a multicell network, Wi-FiS can avoid hidden and exposed terminal problems, while enabling parallel transmissions among multiple cells. We then develop a theoretical model to analyze Wi-FiS’s throughput. Extensive simulations verify that our theoretical model is very accurate and Wi-FiS can improve system throughput of Wi-Fi dense networks significantly.

Virtualization of residential customer premise equipment. Lessons learned in Brazil vCPE trial

This paper presents Telefónica approach for virtualizing residential customer premises equipment (vCPE), showing how the equipment at a customer's home can be simplified and how the management of resources and services improves as a result. This use case of virtualization enables the operator to shift most functions from the residential gateways towards the carrier own network, by running them on general-purpose servers at the operator premises. This makes it possible that network functions such as IP routing, IP address management (DHCP), address translation (NAT), firewall, Set Top Box functionalities (live TV, VoD, etc.), etc. are maintained and upgraded from the most efficient location. Because of the expected high impact onto the economics of the Telco network operations, the virtualization of the CPE is considered by the authors as one promising use case of Network Virtualization technologies. The virtual CPE approach is being tested in Brazil (where Telefónica operates under the Vivo brand), and represents a great opportunity for learning lessons on development and deployment of Virtual Network Functions (VNFs). Some of them are summarized in this paper.

Studi Perancangan Jaringan Worldwide Interoperability For Microwave Access (Wimax) Di Area Banyumas

At present the need for higher internet connection along with the age which is growing so fast. Then there is the latest breakthrough in telecomunications that is WiMAX technology is a wireless broadband technology reffered the IEEE 802.16 standard. WiMAX technology comes with a network of excellence in aspects of data access speed, wide area coverage and the presence of QoS is can allocate frequencies in accordance with user needs using OFDM technology. WiMAX technology can reach area far as 50 kilometers, also allows user equipment (customer premise equipment or CPE) to get a broadband connection without having a direct path (non line of sight, NLOS) to the base station (BS) and provides a total data rate of up to 75 Mbps. Results of this Final project assumed that the area where will be design is Banyumas district. Then final project results of the PRX -100.31 dB; the Total Margin of 23.56 dB; Path los of 134.5 dB; gamma (?) of 4.375; Frequency correction factor (?PLf) of 0,36; antenna correction factor (?PLh) is -3,25; Radius Cells (d) is approximately 1995 meters; area of cell is at 10,34010495 km2 and the number of cells 133
