Hartal, the general strike or total shutdown, is one of the defining features of politics in Bangladesh. While opposition parties proclaim it is one of their only weapons to put pressure on the ruling party, Bangladeshi middle classes and the international (donor) community view hartal as essentially disruptive. Focusing on the local organisation of hartal at the ward level, this article argues that hartal plays a crucial role in the organisation of the local power structure in Bangladesh. By considering hartal as a complex political performance, we are able to show that hartals offer unique opportunities for local party organisers to show, maintain and improve their position in the local power structure. Addressing a multilevelled audience, it enables them to gain access to beneficial patronage relationships with the party (leadership) at the local, regional and national levels. The willingness to take risk and the ability to recruit hartal participants offers important markers to establish and improve these relationships. As such, efforts to move away from hartal to 'less disruptive' forms of protest are misguided.

A simplified millimeter-wave (mm-wave) radio-over-fiber (RoF) system employing a combination of optical heterodyning in signal generation and radio frequency (RF) self-homodyning in data recovery process is proposed and demonstrated. Three variants of the system are considered in which two independent uncorrelated lasers with a frequency offset equal to the desired mm-wave carrier frequency are used to generate the transmitted signal. Uncorrelated phase noise in the resulting mm-wave signal after photodetection was overcome by using RF self-homodyning in the data recovery process. Theoretical analyses followed by experimental results and simulated characterizations confirm the system's performance. A key advantage of the system is that it avoids the need for high-speed electro-optic and electronic devices operating at the RF carrier frequency at both the central station and base stations.
