AT&T 3G Sunset
Product Change Notification AT&T 3G Sunset - Impacts on 4G Devices LTE Category 1, Category 3 and Select Category 4 Models Date: March 9, 2021 I. Product Change Notification Number (PCN) PCN 03092021-02 II. Overview The purpose of this PCN is to avoid service interruption for certain MultiTech 4G products impacted by the impending AT&T 3G network sunset. 4G/LTE Category 1, 3 and 4 devices in the U.S. may no longer attach to the AT&T network after their 3G network sunset, scheduled for late February 2022. Voice-capable cellular modules integrated into several MultiTech products are configured for voice-centric signaling by default. These devices are likely to arrive at a No Service condition after 3G sunset -- even for data-only applications. This is a result of the module requiring a voice signal to connect to networks configured to leverage a combined attach (3G and LTE) for LTE device registration. The MultiTech products detailed in this PCN will be impacted by the 3G sunset. A software configuration change in the cellular module in these products is required in order to avoid a No Service condition. The only exception is for products with cellular modules supporting the IMS service Voice over LTE (VoLTE) and an accompanying VoLTE subscription from your service provider. MultiTech will immediately implement a software configuration change in our manufacturing process to include the required AT command to set a new permanent module default for its User Equipment (“UE”) settings. Note: future module firmware updates may impact this setting. Current default: CEMODE=1 (Voice centric) New default: CEMODE=2 (Data centric) For devices already deployed in the field, you must implement the above mentioned software- configuration change in each device to ensure continued service following the 3G sunset. -
Long-Range Wireless Radio Technologies: a Survey
future internet Review Long-Range Wireless Radio Technologies: A Survey Brandon Foubert * and Nathalie Mitton Inria Lille - Nord Europe, 59650 Villeneuve d’Ascq, France; [email protected] * Correspondence: [email protected] Received: 19 December 2019; Accepted: 11 January 2020; Published: 14 January 2020 Abstract: Wireless networks are now a part of the everyday life of many people and are used for many applications. Recently, new technologies that enable low-power and long-range communications have emerged. These technologies, in opposition to more traditional communication technologies rather defined as "short range", allow kilometer-wide wireless communications. Long-range technologies are used to form Low-Power Wide-Area Networks (LPWAN). Many LPWAN technologies are available, and they offer different performances, business models etc., answering different applications’ needs. This makes it hard to find the right tool for a specific use case. In this article, we present a survey about the long-range technologies available presently as well as the technical characteristics they offer. Then we propose a discussion about the energy consumption of each alternative and which one may be most adapted depending on the use case requirements and expectations, as well as guidelines to choose the best suited technology. Keywords: long-range; wireless; IoT; LPWAN; mobile; cellular; LoRa; Sigfox; LTE-M; NB-IoT 1. Introduction Wireless radio technologies, such as Wi-Fi, are used daily to enable inter-device communications. In the last few years, new kinds of wireless technologies have emerged. In opposition to standard wireless technologies referred to as “short-range”, long-range radio technologies allow devices to communicate over kilometers-wide distances at a low energy cost, but at the expense of a low data rate. -

In the LTE-A system, the maximum bandwidth of a single carrier is 20MHz Participate in the aggregati on of the various LTE carrier is known as the LTE-A mem ber carrier (Component Car rier, CC) Standard Considering the backward compatibility of LTE system, the maximum bandwidth of a single carrier unit is 20M Hz in the LTE-A system. All carrier units will be designed to be compatible with LTE, but at this stage it does not exclude the considerati on of non - backward compatible carriers. In the LTE-A FDD system, the terminal can be configured to aggregate different bandwidth, different number o f carriers. For TDD LTE-A systems, the number of uplink and downlink carriers is the same in a typical scence. In the LTE-A system, CA supports up to 5 DL carriers. -
