What are typical data transmission speeds?

Data transmission speed of cellular transmissions varies based on multiple factors. These range from tower congestion to tower density, carriers and even the weather. Therefore, it is hard to give one specific figure. However, all Hologram SIMs have access to 2G, 3G, 4G, and LTE Cat-M networks where available.

The modems in our Hologram hardware are rated for the following speeds: Download/Upload 5.76/7.2 Mbps for the 2G/3G Sara U201 module and Download/Upload 75/75 Kbps for the Cat-M1 Sara R410 module.

Cat-M1 Speeds

Cat-M1 technology is purpose-built radio technology for IoT and M2M connections that require lower power usage and message bandwidth.

Cat-M1 speeds are slower than other connections by design with uplink and downlink speeds of 375 kbits/s in half duplex mode, so it is best used for applications with low to medium data rate needs. The real advantage of Cat-M1 is lower power usage and module cost.
