HZ1500USB Wireless USB LAN Adapter

INTRODUCTION

All Horizons Wireless products are designed and manufactured by Direct2Data Technologies. Products

are fully compliant with IEEE 802.11b standards and are optimized to provide maximum possible speed

and bandwidth through your Internet connection for fastest uploads and downloads.

The distance capabilities of your wireless network equipment directly affect your signal quality. Distance

capabilities are usually stated in terms of outdoor, open fi eld reach. However, this reach is greatly

diminished indoors by walls, doors, construction techniques and appliances that may block the radio

signal. A wireless network adapter that tests outdoors at 200 feet could, in an indoor environment, provide

20 feet in one direction and as little as 5 or 10 feet in another direction. Factors such as building materials,

fl oor plans and furnishings can greatly impact the signal range, quality and rate of data transmission. The

extent to which your signal is affected varies greatly depending on your environment.

Wireless network products powered by D2D technology will provide better performance than other

products because they can achieve open fi eld distances of up to one mile, (when a D2D enabled adapter

is used in conjunction with a D2D enabled base station). The D2D adapter alone provides 3 to 7 times the

distance of other leading brands. This is suffi cient to reach all rooms in most homes or small offi ces.
