There are two 5 g Routers to choose from the battery Huawei 5g Battery model with WiFi only.
You can take this anywhere ideal for finding the best locations with the best speed. The second is the Huawei 5g Pro Router. This has two ethernet ports and a RJ 11 socket which you can attach a phone to make and receive calls. This model is mains powered.
The mains router costs initially £420. However, you can get it for £28 from Three a month though it is locked to their network. The Battery 5g router costs £299, which you can use in a tent if you wish. The charge lasts a day when in use. On a 5g network you can get 3.3 Gbps if you are in a strong signal area. If you do not have 5g yet then you can get up to 150 Mbps on 4g through these routers. You can then wait for better speeds when network providers upgrade their masts to 5g
