The devices and technologies used in pervasive computing do not lend themselves well to typical data security. This is because they combine in an ad hoc manner within the pervasive network. As such, trust models must be developed in order to ensure tighter security. Other disadvantages of pervasive computing include frequent line connections that are broken, slow connections, very expensive operating costs, host bandwidths that are limited in nature and location-dependent data. All of these instances can impede the security of pervasive computing because they result in multiple system vulnerabilities. One more disadvantages is that pervasive networking include interference-because pervasive wireless operates over radio frequencies-and power issues, but power over Ethernet can help alleviate some of these
