High demands of wireless data service are increase globally and this makes Empirical path loss models of great interest. Path loss Propagation models are useful as predictive tools for receiving signal intensity at any particular distance between the transmitter and the receiver at that particular point, it is important in many ways, such as Base Transceiver Stations (BTS) location, radio coverage area estimation, frequency assignments, interference analysis, optimization transfer, power adjustment and connection budget. This paper presents an assessments and evaluation of five widely used empirical path loss models in predicting signal in the VHF and UHF bands in Kano City, Nigeria. In the work, five error analysis methods are used and a large scale field strength measurement was conducted within Kano State metropolis using specially configured dual band handset, GPS and GENEX® Probe software, data samples were collected along a predefined route Measurement of the drive test was carried out in Kano, Nigeria to obtain path loss data from various base station transmitters at varying distances. The routes covered are Zaria highway through eastern bypass road Dan Agundi to Bayero University, Kano old site, Hotoro GRA, Badawa Layout to SabonGari along MM way and Kabuga to Bayero University New site.It was found that HATA model provides the best results in terms of minimum mean Error, RMSE and SCRMSE. HATA model has the best fit which falls within the acceptable range of ±10dB.

This commentary paper gives a summary of threats in intimate relationships, which are a type of privacy threats which can result inside families, romantic relationships, friendships, and other close relationships. A lot of popular assumptions about privacy are dispatched in these types of relationships. In fact, plenty of other effective measures tend to fail when applied to these intimate threats. We look into a wide range of intimate relationships and define common features. Therefore, based on these features, we then expand on the ramifications for technical privacy design and policy. Then finally suggest a design recommendation. There are two main security issues in intimate relationships, privacy & authentication related issues. Such privacy issues have been noticed in online learning training in post covid era. A great amount of users in intimate relationships are encountering problems in usability. Most of the issues are due to authentication procedures, sharing passwords, etc.Keywords
