“…Therefore, Mode 1 with the 1024-point FFT, and Mode 2 can provide a higher ratio of UL and are effective in various cases, such as monitoring, metering, and surveillance. The pilot patterns of ARIB STD-T103 are roughly divided into the cluster and tile types [1] [18]. In the tile type, pilot subcarriers are placed at the four corners of each resource unit, whereas in the cluster type, they are not placed at the four corners.…”

“…Transmitter Fig. 2 depicts the transmitter block diagram of the ARIB T103/IEEE 802.16n system and the process of each block is presented in [1]. The transmitter performs channel coding, modulation, frequency interleave using partial usage subchannelization (PUSC), inverse FFT (IFFT), and OFDM processes, including CP.…”

“…ARIB STD-T103 was standardized for the WRAN system by the Association of Radio Industries and Businesses (ARIB) of Japan in 2011 to meet the formerly mentioned requirements [1], [18], [19]. In 2013, this standard was standardized as IEEE 802.16n (hereafter referred to as ARIB T103/IEEE 802.16n) [20].…”

“…In our previous shorter version study [1], we proposed a channel estimation method for ARIB T103/IEEE 802.16n downlink in a highly mobile environment to reduce the memory required for reception. The bit error rate (BER) performance was evaluated using 64 QAM-OFDM and maximum-ratio combining (MRC) diversity via computer simulations.…”

“…• We formulated the use cases and specifications of the ARIB T103/IEEE 802.16n for IoT and V2X in the VHF band. • In addition to the computer simulation and experimental evaluation results in [1] and [21], the transmission performance of ARIB T103/IEEE 802.16n with all the modulation schemes, uplink and downlink, and with and without diversity was comprehensively evaluated through computer simulations and experimental analysis of the transmission characteristics of the VHF band. The results of the computer simulation were validated based on the experimental results obtained from our WRAN prototype.…”

This paper presents a comprehensive evaluation of the performance of a super-large-coverage mobile communication system for wireless regional area networks (WRANs) in the very-high-frequency (VHF) band. The system was standardized as ARIB STD-T103 and IEEE 802.16n. It can transmit data over a distance of 10 km or more at a transmission rate of several megabits per second (Mbps). It is particularly suitable for transmitting sensor and monitoring information, including moving images, over a wide area. First, we present some use cases and determine the feasibility of implementing WRANs for vehicle-to-everything (V2X) and the Internet of Things applications. Subsequently, we evaluate the transmission performance and estimate the transmission distance in the VHF-band radio propagation environment through computer simulations and experimental evaluations with our WRAN prototype. In the evaluation, we also adopt several channel estimation methods for a particular pilot pattern in the downlink. Moreover, we demonstrate the transmission distance that can be achieved with and without a multihop relay based on the evaluation results. Single-hop transmission reaches up to approximately 10 km while maintaining transmission speeds of several Mbps on the uplink, when QPSK is used. Conversely, by using multihop transmission, although the transmission speed is approximately 1/2 to 1/6, the maximum transmission distance is approximately 50 km.
