Software, setup, and connectivity resources Analog HotSpot repository, setup notes, software, and documentation alwaysconnected.eu mobile data service for portable and remote hotspot deployments 4G LTE Analog HotSpot - UHF This compact 4G LTE Analog HotSpot combines our proven UHF hotspot platform with an integrated SIM7600G-H 4G LTE modem, making it ideal for portable, vehicle, emergency, travel, backup, or remote installations where fixed internet or local Wi-Fi is inconvenient or simply unavailable. It is built on our 3rd generation Analog HotSpot hardware platform, with improved DC filtering, cleaner RF behavior, stronger thermal performance, and a precision-machined red aluminum enclosure. This model is available only in UHF and only in red aluminum. The hotspot runs smoothly as an SVXLink / EchoLink analog hotspot and is designed for dependable mobile connectivity in the field. The integrated 4G modem supports up to 150 Mbps downlink and 50 Mbps uplink, which is far more than needed for stable analog hotspot traffic. It also works smoothly with alwaysconnected.eu.Currently only an SVXLink Bookworm image is available for SVXLink and EchoLink. Why Built-In 4G Matters No dependency on local Wi-Fi — ideal when the hotspot is used outside the home or at remote sites. Integrated LTE connectivity — the SIM7600G-H keeps the unit connected without needing a separate external router. More than enough bandwidth — up to 150 Mbps downlink and 50 Mbps uplink is comfortably beyond what an analog hotspot needs. Field-friendly deployment — useful for temporary stations, mobile operation, backup links, and out-of-coverage areas. alwaysconnected.eu ready — works smoothly with https://alwaysconnected.eu/. 3rd Generation Hardware Platform Improved DC filtering — additional LC filtering stages reduce ripple and supply-borne noise. Enhanced thermal design — the aluminum enclosure helps dissipate heat during continuous-duty use. Cleaner RF chain — stable transmit behavior with excellent spectral cleanliness. Robust mechanical construction — compact, durable, and better suited to portable and installed use. Proven hotspot architecture — based on the same analog hotspot family already used for SVXLink and EchoLink deployments. Specs at a Glance Feature Specification Frequency Range UHF: 400–480 MHz Output Power 26–28 dBm (~300–500 mW) RX Sensitivity −109 dBm @ 12 dB SINAD Bandwidth 12.5 kHz / 25 kHz 4G LTE Modem SIM7600G-H 4G Data Rate Up to 50 Mbps uplink and 150 Mbps downlink Clock Stability 1 ppm KDS TCXO Audio Codec Wolfson WM8960 ADC / 1 W DAC (48 kHz) Power Input 5 V via micro-USB Power Consumption Less than 3 W idle, less than 8 W during transmission Recommended Power Setup RF.Guru CM-DM USB power filter, short 15 cm cable, and a decent USB-C power supply Enclosure Red aluminum Software SVXLink / EchoLink image preloaded Included with the Product Complete tested 4G LTE hotspot in a red aluminum enclosure Integrated SIM7600G-H 4G modem Preloaded SD card with our latest image Key Features Integrated 4G LTE connectivity for independent deployment Independent TX/RX frequencies, CTCSS, and CDCSS Adjustable RX/TX gain levels Status LEDs: Signal/Tone and TX/PTT Ultra-stable 1 ppm TCXO Compact red aluminum enclosure with strong thermal behavior Power Supply and Filtering The 4G LTE Analog HotSpot is powered from a standard 5 V micro-USB input. In idle, the unit typically consumes less than 3 W. During transmission, power consumption remains below 8 W. For the cleanest installation, we recommend using our CM-DM USB power filter together with a short 15 cm USB cable. Any decent USB-C power supply with sufficient current capability will work well, provided the cable and filtering are suitable for RF use. Recommended Power Setup Input voltage — 5 V via micro-USB. Idle consumption — less than 3 W. Transmit consumption — less than 8 W. Recommended filtering — RF.Guru CM-DM USB power filter. Recommended cable — short 15 cm USB cable to reduce unwanted pickup and cable-borne noise. Power supply — any decent USB-C power supply with enough current capability is suitable. UHF RF Measurements All measurements in this section apply to the UHF RF platform used in this product. Sensitivity Measurements The 12 dB SINAD sensitivity was determined using a 1 kHz tone FM-modulated at a 2.5 kHz deviation and injected into the receiver. This gives a realistic view of actual receive performance under standard SINAD measurement conditions. RF Cleanliness Measured with a calibrated setup and 36 dB attenuator, the UHF RF chain shows very clean output behavior. Worst-case harmonic level is −63.56 dBc and the spectrum confirms excellent suppression of unwanted products inside and outside the occupied channel. These measurements reflect the UHF hardware platform used for this model.
