In the diagram below, one Remote is configured for static hopping and will only associate with AP1 because they are both using Offset 0. The hand-off configured Remote, using its AP Locations file, may connect to AP1, AP2, or AP3. The Remote does this by determining the Offset for each AP, then configuring its radio.

[1.75 MHz or 3.5 MHz] In a mobile or portable application, a Remote radio can move and associate with different APs depending on its location. The process by which the Remote ends the connection with one AP and begins a connection with another AP is called “hand-off.
Advanced Control Menu Invisible place holder Figure 3-38. Advanced Control Menu (Hopping with Handoff Mode, Remote Only) AP Selection Mode—The method used by the Remote to determine what AP to connect to. It may be based on Signal, Distance and Bearing (from the AP's GPS coordinates in the AP locations file), or Connection.

For example, the third SNR value in Column D is 11.4 dB (8.4 + 3 = 11.4 dB), and the third SNR value in Column E is 17.1 (11.1 + 3 + 3 = 17.1 dB). Note that with a Hysteresis Margin of 3 dB, there is an overlap of 3 between the Max SNR of one modulation and the Min SNR of the next higher modulation. In this case, if a link is operating with an SNR of 15 dB, then QPSK-3/4 modulation is used. The SNR must go above 17.1 dB before the link shifts up to 16QAM-1/2 modulation.
NOTE: To restore the COM1 port to support Management System services, connect a terminal to the port, select the proper baud rate (115,200 is default), and enter an escape sequence (+++) to reset it to the console mode. There is a configuration parameter for the console baud rate and another parameter for the serial data baud rate. These items can be different, so when switching out of data mode to console mode, the port might also change its baud rate. TCP vs.
UDP Multicast IP provides a mechanism to perform a limited broadcast to a specific group of devices. This is known as multicast addressing. Multicast addressing requires the use of a specific branch of IP addresses set apart by the Internet Assigned Numbers Authority (IANA) for this purpose. UDP multicast is generally used to transport polling protocols typically used in SCADA applications where multiple remote devices will receive and process the same poll message.

In TCP mode, the transceiver remains in a passive mode, offering a socket for connection. Once a request is received, data received at the serial port is sent through the IP socket and vice versa, until the connection is closed or the link is interrupted. In this mode, the transceiver behaves the same, whether it is an Access Point or a Remote. (See Figure 3-46 and Table 3-4) NOTE: The TCP session has a timeout of 10 minutes (600 seconds). If inactive for that time, the session is closed.

There are two major areas for possible improvement—the radio and the data network. These sections provide a variety of items to check in both categories, and in many cases, ways to improve performance. NOTE: Antennas are one of the most important portions of the wireless system. A properly installed antenna with an unobstructed path to associated stations is the optimal configuration, and should be among the first items checked when searching for performance gains.
