The rough differences to BG96 have been highlighted in color. The fact that a BF77 requires an area of only 14 mm x 15 mm is not to be mentioned. I have marked that there are now versions with Wi-FI location. The BG95 is available with fallback level GPRS. With BG77 this is not supported. The PA for GPRS contradicts the saving of installation space. That the currents have dropped from 10 uA to 3 uA, I have not marked either. 3 uA is the standard in PSM mode for NB-IoT and LTE-M today. The operating voltage from 3.2 Volt to 4.5 Volt is certainly still a mistake in the data sheet. The chipset needs only 2.4 Volt. If you really want to save energy, you should put some power into the antenna development. +\/- 3 dB antenna gain or loss decide about 2.5 or 5 or 10 years from the same battery. 1.5 dB disappear quickly in the matching circuit and the next 1.5 to 2.5 dB in the plastic housing. A battery then &#8220;eats&#8221; the next few dB. A small BG77 with a small battery and a small antenna leads to a small device, but too small is not always the best for the radiation of the radio wave. If you are not sure, feel free to contact me. Furthermore I can help with evalation kits for Quectel BG77 and BG95, wireless modules for the first own PCBs and with reference designs for several applications. harald.naumann (at) lte-modem.com<\/p>\n<h2>PDF of Quectel BG95 \/ B77 for downlad:<\/h2>\n<p><a href=\"http:\/\/www.gsm-modem.de\/M2M\/.\/wp-content\/uploads\/2019\/01\/Quectel_BG77_LTE_Specification_V1.0_Preliminary_20181227-Tekmodul.pdf\">Quectel_BG77_LTE_Specification_V1.0_Preliminary_20181227-Tekmodul<\/a> <a href=\"http:\/\/www.gsm-modem.de\/M2M\/.\/wp-content\/uploads\/2019\/01\/Quectel_BG95_LTE_Specification_V1.0_Preliminary_20181227-Tekmodul.pdf\">Quectel_BG95_LTE_Specification_V1.0_Preliminary_20181227-Tekmodul<\/a><\/p>\n<div class=\"shariff shariff-align-flex-start shariff-widget-align-flex-start\"><ul class=\"shariff-buttons theme-default orientation-horizontal buttonsize-small\"><li class=\"shariff-button twitter shariff-nocustomcolor\" style=\"background-color:#32bbf5\"><a href=\"https:\/\/twitter.com\/share?url=http%3A%2F%2Fwww.gsm-modem.de%2FM2M%2Fm2m-componets%2Fdata-sheet-nbiot-ltem-modules-quectel-bg77-bg95%2F&text=Data%20sheet%20NB-IoT%20%2F%20LTE-M%20modules%20Quectel%20BG77%20and%20BG95\" title=\"Share on Twitter\" aria-label=\"Share on Twitter\" role=\"button\" rel=\"noopener nofollow\" class=\"shariff-link\" style=\";
