Wireless WiFi coverage, what is seamless roaming, load balancing.

1. What is wireless AP
An abbreviation for wireless APs, English access point, access points, Access nodes, session points. At present, the two types of "AP" and "Access point" is a meaning, that is, the wireless AP is also called an access point. Wireless AP via wireless card can be connected to multiple laptops, mobile phones, etc., can be understood as a wireless switch
Wireless APs are not equivalent to wireless routers, and home wireless routers are integrated by small wireless ap+ routers (Broadband) + switches to avoid home purchases of multiple electronic products. There are routing functions called wireless routers, no routing function called wireless APs, in the general medium-sized enterprise network, switches, wireless APs, routers are separate separate, a single more powerful and professional. For example: Enterprise-Class router W2004 with 400 people, UF2029 roaming wireless AP Access number 100~128 people. Switches are commonly used with 24-port gigabit or gigabit switches.
2. What is roaming
Wireless terminals move from Zone 1 to Zone 2, and wireless terminals can "roam" from one AP to another if AP1 and AP2 have the same wireless name SSID and password. Different ways of switching between APs are divided into: there are seam roaming and seamless roaming.
The wireless terminal moves from the AP1 to the AP2, when moving to AP1 no signal when the drop off, and then reconnect to the ap2,ap between the switch when there is a disconnect process, known as the seam roaming.

3, what seamless roaming
The wireless terminal moves from Zone 1 to Region 2, and when moved to the AP1 signal is low, it automatically switches between connecting to Ap2,ap, which is called seamless roaming. Ordinary APS do not support seamless roaming, to be implemented through roaming wireless AP+AC, when selecting a device to determine whether the AP and AC really support seamless roaming features, avoid the business to play word games, roaming and seamless roaming is not the same function and concept.
4, what balance of debt
Load balancing balances the client load in the wireless network, ensuring the performance and bandwidth of each client terminal. It is suitable for wireless network with a large number of wireless access and heavy load, which effectively guarantees the reasonable access of clients.

Application Case:
A group of wireless office network, planning 200 users wireless Internet access, usually about 120 people, require seamless roaming, load balancing, to avoid the concentration of people connected to an AP caused by overloading the impact of speed and performance.

The load balancer is implemented by roaming wireless AP+AC, which is set up in the AC management interface, for example: AC UF2000 set Wireless Group, tick enable load balancer, and set balance number (default value 30), when the AP access number is more than 30 o'clock load balance, effectively avoid when 120 people online, One of the APS access 110 people overloaded, another AP Access 10 people idle resources.

In the planning of Enterprise Wireless network, first of all, we should consider the coverage of wireless APs to ensure the wireless signal coverage in place. Second, to consider the number of wireless APs access, depending on the hardware, the general "thin AP" for 10~20 clients, more expensive and more professional "fat AP" can support 100~200 wireless connection.
A slightly larger corporate wireless network, there will be multiple APs to increase the range of wireless coverage. Multiple APs to avoid the same frequency interference, support seamless roaming and load balancing, to provide customers with a seamless network environment. As multi-AP interference between the same frequency, seamless roaming and load balancing is more complex, so network planning when the number of APS should not be too much, network size slightly larger, it is recommended to use a more professional "fat AP" to tap multiple antennas, so planning more efficient, more concise.
