Difference Between GSM, GPRS, EDGE, 3G, WCDMA, HSDPA and 4G
Difference between GSM, GPRS, EDGE, 3G, WCDMA, HSDPA and 4G It's a very basic and non-technical comparison. GSM GSM, stands for Global Systems for Mobile Communications, is basic standard bearer of 2G technologies. It is mainly used in mobile communication. Short Messaging System (SMS) was introduced into GSM networks along with capability to download content from various service providers. The content could ring tone, logos and picture messages. It can support Voice telephony and data however the data rate is only 9.6Kb/s, that is very low bit rate for date communication. GPRS GPRS, stands for General Packet Radio Service, is used to give higher data speed over GSM. It is not the replacement of GSM. It is just an extension to the older GSM technology to gain faster speed. Multimedia Messaging System or MMS is the feature of GPRS. It allowed subscribers to send videos, pictures, or sound clips to each other just like text messages. GPRS also provided mobile handset the ability to surf the Internet at dial-up speeds through WAP enabled sites. GPRS offers higher bit rate (Up to 171kb/s) by usage of A packet-linked technology over GSM. EDGE EDGE stands for Enhanced Data Rates for GSM Evolution. This technology, also termed as Enhanced GPRS. This is a technology that uses the same equipment as GSM with only a few minor modifications to provide faster data speeds and is often regarded as a stepping stone towards 3G thus it is called 2.5G. EDGE gives the users the inimitable chance to increase the throughput capacity and the data speed at least 3 to 4 times higher to what GPRS offers. -
Information Technology Services Travel Tips for Smartphones
Information Technology Services Travel Tips for Smartphones Reducing charges on your smartphone when travelling outside Canada You can use data services when travelling outside Canada; however cellular data usage is not included by default in plans while roaming and it comes at a premium. Without a travel bundle, when you are outside of Canada, you could incur significant data roaming charges when you use services such as email, web browing and app downloads and services. When you are outside of your Canadian carrier network: . Your smartphone will display a service provider name other than your carrier. You will receive a text message welcoming you abroad. Read the rates sent in a free text message for voice, text and data roaming so there are no surprises on your bill. The advertised rates will be higher than rates of a travel bundle. You will also receive this same message when you have added travel bundle(s), the message will not reflect the lower rates you will have in place. Tips to reduce charges Disable roaming To prevent roaming charges completely when travelling, put your smartphone on Airplane or Flight mode. If you still want your device available for voice calls or texts, turn data roaming off. Email, web browsing and other functions requiring data services will only be available when you are connected to wi-fi. Please note wi-fi may not always function as a substitute for data roaming. Ensure data roaming is disabled if you want to use wi-fi only. If you do not, your smartphone may switch to a mobile network if the wi-fi signal becomes weak or you leave the coverage area, thus potentially incurring excessive data roaming charges. -

International Journal of Scientific & Engineering Research, Volume 5, Issue 1, January-2014 685 ISSN 2229-5518 A Survey on Mobile Wireless Networks Nirmal Lourdh Rayan, Chaitanya Krishna Abstract— Wireless communication is a transfer of data without using wired environment. The distance may be short (Television) or long (radio transmission). The term wireless will be used by cellular telephones, PDA’s etc. In this paper we will concentrate on the evolution of various generations of wireless network.

In this paper, we present a detailed survey of various resource allocation schemes that have been considered for the cellular network’s operation in the unlicensed spectrum. The key channel access mechanisms for cellular network’s operation in the unlicensed bands are discussed. The various channel selection techniques are explored and their operation explained. The prime issue of fairness between cellular and Wi-Fi networks is discussed, along with suitable resource allocation techniques that help in achieving this fairness. We analyze the coverage, capacity, and impact of coordination in LTE-U systems. Furthermore, we study and discuss the impact and discussed the impact of various traffic type, environments, latency, handover, and scenarios on LTE-U’s performance. The new upcoming 5G New Radio and MulteFire is briefly described along with some of the critical aspects of LTE-U which require further research. -

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. -
