Network device

Embodiments herein describe mounting one or more lasers onto an AP to generate a laser pattern on a surface representing the coverage area of an antenna in the AP. In one embodiment, the antenna is a steerable antenna that can be electronically or mechanical steered to point to different directions (without moving the AP as a whole). The laser or lasers can be used to visualize the coverage area of the steerable antenna when pointing in different directions. Advantageously, a technician can use the laser or lasers to identify a location where, if steered, the antenna would provide the desired coverage area. The technician can then steer the antenna to point in that direction to provide the desired radio frequency (RF) coverage.

Visual antenna aiming

An electronically a steerable and switchable antenna array is provided that can produce a first beam with a first coverage range and a second beam with a second coverage range by selecting one of a first and a second beamwidth for both the first and second beams; in response to selecting the first beamwidth: switching signal inputs to narrow-beam antenna arrays; steering the first beam to one of a first positive, negative, or zero offset position; independently steering the second beam to one of a second positive, negative offset, or zero offset position; and transmitting signals received from the signal inputs via the first beam and the second beam; and in response to selecting the second beamwidth: switching signal inputs to wide-beam antenna arrays; and transmitting signals received from the signal inputs via the first beam and the second beam.

Electronically steerable antenna array

The embodiments herein use polarization diversity between antennas where the antennas for one cell are, e.g., horizontally polarized and antennas for the other cell are vertically polarized. In one embodiment, the antennas for a macro cell are vertically polarized while micro cell antennas are horizontally polarized. In one example, the micro cell antennas are printed antennas that form a loop that is co-planar with the magnetic fields generated by the macro cell antennas when transmitting. Because the magnetic fields are co-planar (rather than orthogonal) to the current flowing through the loop in the micro cell antenna, the effect of the electromagnetic signals emitted by the macro cell antenna is reduced. This may permit dual radio network devices to have improved performance when operating simultaneously&#x2014;e.g., when the macro cell radio is transmitting and the micro cell radio is receiving at or near the same frequency band.

Interface for an electronic unit

A clip assembly having first and second clip members. In an example embodiment the first and second clip members are generally matching. Each clip member includes a mounting member adapted to envelope and slide along an edge of an associated mounting support, such as a ceiling T rail. Each clip member further includes a spacer member arranged generally parallel to the mounting member. The clip members are adapted to be mutually engaged by the engaging means included in respective spacer members when the first and second clip members are drawn together as a result of the respective mounting members sliding toward each other along opposed edges of the mounting support. The clip assembly is secured to the mounting support by an external screw and capable of being easily released from it, when necessary.

Clip assembly

An adjustable clip having a first clip member and a second clip member. The first clip member includes a first slide tang that includes a first end, a second end with a detent tang. The second clip member includes a second slide tang having a first end, a second end with a detent tang. The slide tangs of the first and second clip members are positioned over the rail for installation and the slide tangs are moved towards each other until the detent tangs of the first and second clip members engage opposing ends of the rail.

Adjustable clip

A stacked patch antenna is disclosed which includes a first antenna element and a second antenna element for cooperating with the first antenna element. These antenna elements are preferably a passive parasitic element in combination with a driven element. A flexible substrate is provided having first and second opposing surfaces, each respectively in contact with the first and second antenna elements. The flexible substrate preferably has a desired dielectric property to provide a desired capacitance between the antenna elements. One or both of the antenna elements are formed on the respective opposing surface. The antenna element is preferably formed by printing.
