Troubleshooting LTE Issues

This section provides troubleshooting tips for resolving common issues while working with Ruckus LTE Access Point (AP). All Ruckus LTE AP models have common software modules that can be used interchangeably. The document is valid for all the Ruckus LTE AP models.

After successful setup and commissioning, Ruckus LTE APs are capable of transmitting 20 MHz bandwidth TDD-LTE and providing wireless coverage to relevant LTE devices.

Use this document to debug any setup or performance issues that are encountered during routine operation of the Ruckus LTE AP. Each LTE AP is powered by a managed PoE+ switch or a PoE injector (PoE+ desirable), or DC power adaptor (for Q710 AP) whichever is available.

After booting up, LTE APs send DHCP requests. The LTE APs rely on an external DHCP server to provide each AP, a routable IP address that enables it to route and send connection requests to EMS (Ruckus LTE AP Management), Network (EPC), Timing Master, and SAS.

You can configure an LTE AP to complete the following actions:

  • Obtain its timing information from the GPS satellites, and assume the role of a Master PTP source for other LTE APs in the network.
  • Assume a PTP slave role and obtain its timing information from another AP that is the designated Master (that is reachable by IP address) for that venue.

In the current system implementation, each venue can only have one LTE AP assuming the Timing Master source role. There can be a maximum of up to 32 devices acting as timing slaves per master. In addition, there can be multiple LTE APs with timing source set as GPS satellites and can obtain their timing information directly via GPS satellites (if capable).

For an LTE AP to obtain timing via GPS and/or function as Master timing source, place the AP such that it has direct line-of-sight view with open sky or as close to the outside facing windows or doors.
