WiFi Module - Ultra Long Range High Gain w/ 5dBi Antenna (C5 module wifi ultra long range)
This Ultra Long Range High Gain 5dBi USB WiFi Dongle is great if you're connecting to distant WiFi signals with your Raspberry Pi, and want a little more range! We've tested the signal in an open area to a useable straight line range of 100m. We probably would have got more if it wasn't for those pesky tree's!
Our long range Raspberry Pi WiFi dongle utilises the plug and play Ralink RT3070 Chipset, which requires no set up or installation on Raspian, XBMC or OpenElec. It's larger than the other dongles we sell, but it features an external 5dBi High Gain detachable antenna to give you a wireless reception range 6 times wider than that of a standard 54Mbps USB Adapter; and subsequently access to distant and weak WiFi signals! Even with all that power, these dongles are low draw (<150mA nominal draw), and connect to the Raspberry Pi's USB via a short USB/Mini-USB cable without the need for an external USB hub!
ModMyPi's Ultra Long Range High Gain 5dBi USB WiFi Dongle Features:
- Tested for Compatibility with the Raspberry Pi
- Plug & Play - Requires No Installation. Can be used straight from the GUI via the WiFi Config Program.
- Plugs into the Raspberry Pi via a USB to Mini USB cable - Requires No External Power.
- Ralink RT3070 Chipset
- Features a 5dBi High Gain Detachable External Antenna for Extra Range. (Antenna Connector RP-SMA)
- Fully CE Compliant to 2017 Standards (EMC EN 301 489-17 V3.1.1)
Specification
- Complies with IEEE 802.11n (Draft 2.0), IEEE 802.11g, IEEE 802.11b Standards
- Wireless Speed Up to 150Mbps over 11n
- Supports 20MHz/40MHz frequency width
- Transmit Power 5dBi (Max)
- Provides two work modes: Infrastructure and Ad-Hoc
- Supports Soft AP to allow other wireless network to be connected
- Operating Temperature: 0℃ to 45℃
