A summary of several criteria for choosing a wireless router when buying

Wireless router selection standard 1, wireless standard

We often see a product specification that follows the IEEE802.11B,IEEE802.11G standard, which is the wireless protocol standard. Perhaps everyone hears these will be big, said simple point, 802.11b is the 11M speed to the Internet, and 802.11g is to 54M speed to the Internet. At present, the mainstream of the market is 54M products, so we must first look at the purchase is not the mainstream products. Although the market has 108M products, but relatively high prices for ordinary users 54M products can fully meet the needs of the Internet.

Wireless Router selection standard 2, transmit power

We know that the unit of measure of power is watt. In the same way, wireless devices also use transmitting power to measure the performance of the transmitter. The unit of measurement of the transmitting power is dbm or MW. As with the brightness and wattage of the light bulb, the transmission distance of the wireless device is similar to that of the transmitting power. With the increase of transmitting power, the transmission distance will also increase. Currently the international regulation of the maximum launch power of 20DBM (or 100MW), but now the market most of the products are not up to this value, we are in the choice of course the closer the better.

Wireless Router selection standard 3, antenna gain

Wireless products are mostly antennas, this antenna can be good or bad for wireless products have a direct impact on the selection of routers is a must consider the problem. The function of the antenna is a very popular way of understanding is actually an amplifier, to receive and send all have an enlarged role. We usually say that the antenna gain, the gain of the unit of measurement for DB, the greater the gain, the better the signal transceiver. At the same time, the antenna gain size is not only related to the size of the antenna, but also has a great relationship with the internal materials and workmanship of the antenna. At present, the products in the market are mainly 2dB and 5dB products, however, some products in the antenna claimed to be 5dB products, but actually in the workmanship and materials are not good enough, so up to 5dB. The author in the market turn on the time found Netcore (Lei branch) a new one without line by, this route I tried, Performance is very good. It is worth mentioning is that its antenna to do very well, is the standard 5Db antenna size, excellent workmanship.

Wireless Router selection standard 4, product brand

Wireless routers, including the ability to share broadband Internet access and wireless client access capabilities, product performance is not sloppy. Select a number of brand-name products, such as Linksys, Netcore (Lei branch), NETGEAR (U.S. network) and so on, due to large-scale manufacturers have more strength, will adopt brand-name CPU and wireless chip, product performance and transmission power is guaranteed, in support of access to the number of hosts, security programs, Wireless coverage, settings management, software upgrades and so on will be guaranteed.

Wireless Router selection standard 5, simple installation

For ordinary home users, network knowledge is limited, so we choose the best product is a simple browser-based configuration of the management interface, can have Intelligent Configuration Wizard, can provide software upgrades. I was fortunate to have tried several wireless products, in these brands, Netcore (Lei Branch) of the router, in the product upgrade to do relatively good, its upgrade package faster, at the same time is life-long free, after-sales service is also good.
