For the past two years, Texas Gov. Greg Abbott has sought to finish building the wall that former President Donald Trump started to build along the border between his state and Mexico. This wall is the priority for Mike Brown, the newly named Texas border “czar.” This effort entails significant costs, resistance from local property owners and interest groups along the border, and technical challenges due to terrain issues. It also takes time. The urgency of the border demands a response that is rapidly deployable, low-cost, and creates minimum impact on local interests. Fortunately, modern sensor and networking technologies offer a solution: Texas should create an electronic fence based on a fiber-optic linear ground detection system (LGDS). I have written more on this subject here.
