Hello everyone, I have a problem with the download speed of the WP7702 under LTE. The download speed of the modem is very very slow in the LTE network (519 kB in 44.0 seconds). I use a MangoH yellow board with LTE SIM card. The legato version is “mangOH yellow wp77xx (Modem=R13, Legato=19.11.3-1)”. I modified the “httpGet”-example a little bit to test the download speed. The following source code was modified by me: ```auto static size_t PrintCallback ( void *bufferPtr, size_t size, size_t nbMember, void *userData // unused, but can be set with CURLOPT_WRITEDATA ) { static uint uiSumme = 0; uiSumme += size * nbMember; //printf("Succesfully received data:\n", size * nbMember); //fwrite(bufferPtr, size, nbMember, stdout); LE_INFO("Received data: %u / %u \n", size * nbMember, uiSumme); return size * nbMember; } ``` The connection state before starting the app is: ```auto root@swi-mdm9x28-wp:~# cm radio Power: ON Current Network Operator: Telekom.de Current RAT: LTE network (LE_MRC_RAT_LTE) Status: Registered, home network (LE_MRC_REG_HOME) Signal: Very strong signal strength (5) PS: Packet Switched Registered, home network (LE_MRC_REG_HOME) root@swi-mdm9x28-wp:~# cm data Index: 1 APN: internet.t-mobile PDP Type: IPV4V6 Connected: yes Auth type: PAP User name: t-mobile Password: tm Interface: rmnet_data0 Family[IPv4]: inet IP[IPv4]: 10.x Gateway[IPv4]: 10.x Dns1[IPv4]: 10.x Dns2[IPv4]: 10.x Family[IPv6]: inet6 IP[IPv6]: 2a01:x Gateway[IPv6]: 2a01:x Dns1[IPv6]: 2a01:x Dns2[IPv6]: 2a01:x ``` root@swi-mdm9x28-wp:~# app start httpGet ```auto Jul 14 11:25:35 swi-mdm9x28-wp user.info Legato: INFO | supervisor[26321]/supervisor T=main | proc.c proc_Start() 1363 | Execing 'httpGet' Jul 14 11:25:35 swi-mdm9x28-wp user.info Legato: INFO | supervisor[26321]/supervisor T=main | resourceLimits.c SetRLimitValue() 301 | Setting resource limit maxCoreDumpFileBytes to value 524288.

Is it same behavior for wget instead of legato app? Have you tried newer FW for WP77? (e.g. R14 or R15) ```auto swi-wp77_5.0.1 │ SDK for WP77 (Release 14.1 + Legato 19.11.5) │ wp77xx,stable │ │ swi-wp77_5.0.2 │ SDK for WP77 (Release 14.1 + Legato 19.11.6) │ wp77xx,dev │ │ swi-wp77_6.0.0.beta │ SDK for WP77 (Release 15 + Legato 21.05.0) │ latest,wp77xx,stable │ ``` ---

Hello, I’m from the same company as Maik. I installed the sdk swi-wp77\_5.0.1. The download speed from MangOH Yellow is slightly faster, 30 seconds instead of 44. ```auto root@swi-mdm9x28-wp:~# wget --output-document=/dev/null https://www.informationweek.com ``` The same download from PC takes only 0.3 seconds. What can we do? ---

are you using NBIOT network or LTE CAT M? Please note that you cannot directly compare with PC as the download speed is different. ---

I checked the data rate of the MangOH modem again. ```auto Download time for 544 kByte: 23 seconds (24 kByte/s) ``` This results in a download rate of abaut: ```auto 240 kbit/s ``` Is this correct for the modem in LTE cat M1 Mode or too slow? Usual LTE data rates are in the range of more than 50 MBit/s. ---

LTE Cat M is for low data rate… > **[Pros and Cons of Cat M for Cellular IoT](https://www.twilio.com/blog/when-to-use-lte-cat-m)** > > Cat M is cellular connectivity for “massive IoT”, with key benefits for both network operators and IoT builders, but also some constraints. ---
