Most cordless phones can work a few hundred feet from their base. That's fine for most homes and offices, but not nearly enough for a ranch, farm, car lot, campus, warehouse or a big office building or store.EnGenius Technologies has been marketing long-range cordless phones in the US for about a decade. EnGenius is part of Senao, a Taiwanese manufacturer of phones and wireless data equipment. Some Senao phones can go dozens of miles, but they're not legal in the US. The EnGenius phones are legal here, and can usually reach a mile or more. They have more "horsepower" than other cordlesses, and can even punch through metal walls.
The first generation EnGenius was independently tested to have a five-mile range. Unless you live in death valley, you probably won't reach that far, but coverage of 12 floors in building, 250,000 sq. ft. in a warehouse, and 3,000 acres on a farm, ranch, car lot or campus is not unusual. That's more than 130 million square feet!
EnGenius was one of the first companies to offer a cordless phone with a separate base that can be positioned for maximum range, while the handset needs just a charging cradle, but no phone jack. They were also one of the first companies to offer multi-handset cordless phone systems with handset-to-handset intercom.
EnGenius "DuraFons" are extremely rugged. They are industrial strength phones, built to be dropped and splashed. In addition to providing phone service, they also act as walkie-talkies, and provide paging from one handset to multiple handsets.
Several DuraFon systems are available, for 1, 4 or 32 lines; and up to 9, 32, or 90 handsets. A DuraFon can be connected directly to phone company dialtone, or used with another phone system. Many accessories are available, including an external range-boosting antenna. More info is at www.engenius.info.
