Wireless IT and RF Infrastructure for Stores

INTRODUCTION This document describes the security implications of the new wireless IT infrastructure provided to stores. In this document, the risks associated with end user devices are recorded elsewhere, so we will focus on issues related to the risk of device authentication using preshared keys. The following is an excerpt from TAD. Currently there are many store devices and applications that rely on existing Stores RF infrastructure. The current RF system was first introduced to the store several years ago.

A communication interface configured to receive an RF signal at a location of an entity from a wireless local area network and configured to include a first identifier for a wireless local area network; A mobile computing device comprising a processor. The external server includes a first signal including a first identifier of the wireless local area network, a display, and an online portal for displaying the entity.

Historically, wireless sensor networks have been serving by some combination of traditional cellular or local solutions such as WiFi, mesh and local RF (Bluetooth, NFC etc). For some fundamental reasons these solutions could not provide the necessary catalysts to push IoT to the cutting edge and mainstream. First of all, these traditional methods (Wi-Fi and Mesh) require a wired power supply or replaceable / rechargeable battery every 1 to 2 days. It limits IoT applications to existing power cords or power cords only when they need to be installed, so we can only provide the most obvious and powerful cost saving applications. Second, the coverage and coverage per access point is limited. Therefore, in order to prevent many applications from becoming impossible, the application needs to stay in a very limited area around the wireless source. Third, they are expensive to use. Even after several years and over 1 billion modules, the cost of the LTE module still exceeds $ 40.

In outdoor wireless networks, the wireless mesh network is the third topology followed by point-to-point and point-to-multipoint for building a wireless network infrastructure. Each device in the wireless mesh network is often referred to as a mesh node and is connected to a plurality of other mesh nodes at the same time. Since each mesh node reaches other nodes via multiple hops and other nodes can be used as repeaters, the wireless mesh network is also a multihop network. The main advantage of a wireless mesh network is that the mesh network can reroute traffic over multiple paths to cope with link failures, interference, power failure, or network equipment failures, resulting in inherent redundancy or reliability It is in.
