What transmit power levels can be set on the P-320 and P-360 ?

The P-320 and P-360 can be configured to transmit at the following power levels: 0dBm, 6dBm, 10dBm, 14dBm (default), 16dBm and 20dBm.

What is the delay spread of the P-320 and P-360 ?

The targeted Delay Spread of the P-320 and P-360 at 11Mbps is 125ns, and at 5.5Mbps it is 250ns.

What is the coverage pattern from the P-320 and P-360 ?

The P-320 and P-360 are equipped with internal vertically polarized 6dBi directional antenna for transmit and receive, the horizontal beam width is 85° with no downtilt. The P-320 and P-360 are also equipped with a horizontally polarized 4dBi receive-only secondary antenna with a 65° horizontal beamwidth. Plots of the antenna patterns can be found here p320-p360antennaspattern.pdf

What is the coverage pattern from the P-380A ?

The P-380A is equipped with an internal 10dBi directional antenna, the horizontal beam width is 47°, the vertical beamwidth is 48° with no downtilt. A Plot of the antenna patterns can be found here p380a-antennapattern.pdf

What are the best channels to use if I need more than 3 APs in the same area ?

The recommended minimum channel separation between adjacent Wi-Fi APs is 5 (e.g. channels 1, 6, 11). Under some circumstances it is possible to reduce this channel separation to 4, or even 3 channels to allow more APs to be installed within the coverage area. When reducing to these smaller channel separations, it is essential to provide a greater physical separation between the APs (i.e. >5m (17ft)). In N. America: only 11 channels are available so in dense AP environments channels 1, 4, 7, and 10/11 may be used.

In Europe: 13 channels are available so channels 1, 5, 9 and 13 may be used or under some circumstances channels 1, 4, 7, 10 and 13.

Other Regulatory Regimes: The number of channels available and the spacing used will depend on local regulations.

Can I have 2 APs in the same coverage area set to the same channel ?

If 2 APs within range of each other are set to the same channel, they will "contend" with one another for the 11Mbps of bandwidth avaialble on that channel, i.e. all users associate to those 2 APs will be sharing the 11Mbps of available bandwidth.

Can I attach an external antenna to the P-320 or P-360 ? ...and if so what connectors are required ?

It is possible to attach an external antenna to both the P-320 and P-360 using the A-103 "Pigtail" cable. The A-103 cable has an MMCX connector for the primary antenna jack inside the AP casing and a standard N-type (male) connector for the external antenna.

What is the antenna connector on the P-380N Router/AP ?

The P-380N Router/AP comes equiped with a Reverse Polarity N-type connector. There is the option to use the A-102 short antenna cable to convert the RP N-type connector to a standard N-type (male) connector for the external antenna.

Which is the primary antenna jack inside the P-320 and P-360 AP casings ?

The primary antenna inside the P-320 and P-360 casing is the vertically polarized antenna with the large backing plate located towards the bottom of the unit next to the radio PCB.

Which is the primary antenna on the P-560?

The left hand antenna when viewed from the front of the device is the primary antenna (i.e. used for transmit and receive), see this graphic

What is the receive sensitivity of the P-320 and P-360?

The receiver sensitivities of the P-320 and P-360 are as follows: 

11Mbps: -84dBm.

5.5Mbps: -87dBm.

1Mbps: -90dBm.

Can I use an external power supply on the T-316 ethernet client instead of the supplied USB cable ?

It is possible to use an external power supply for the T-316 ethernet client instead of the USB cable supplied. The power supply should deliver a stabilised 5V DC at 1.5A, the centre-pin on the connector is +ive. The Gemtek Systems' X-103 power supply can be used to power the T-316 ethernet client.

What is the power consumption of the P-320 and P-360 APs, the P-380 Router/AP and the T-316 ethernet

Please see the power consumption spreadsheet.xls

Does the E-810 PoE switch support 802.1q VLAN tags ?

Yes, the E-810 supports 802.1q VLAN tags and passes tagged ethernet frames through transparently.

How do I get rid of the certificate warning message when my users try to access the Internet through

There are 2 ways to prevent users encountering the certificate warning pop-up:

1、Purchase a certificate from a Public Certificate Authority (e.g. Verisign) for each access controller on the network, and upload the certificates to those devices.

2、Move the user login page to a back-end Web server with a valid certificate, and use the "extended UAM" method for user login.

 

Do you have any configuration guidelines for common RADIUS servers ?

Configuration guidelines for the Microsoft RADIUS server are available here radius_gx000_cn.pdf

I having problems with using the WISPr specified VSAs, do these work with Gemtek Systems' products ?

The WISPr VSAs must be specified in the RADIUS server using "WISPr-" as a prefix, i.e. instead of just "Bandwidth-Max-Up" or "Bandwidth-Max-Down" use "WISPr-Bandwidth-Max-Up" and "WISPr-Bandwidth-Max-Down".

Is there a RADIUS dictionary file available for me to import onto my server ?

A RADIUS dictionary file is available here dictionary.wispr-g6000.

Are Gemtek Systems' products compatible with the iPass GIS interface specification ?

Yes, all Gemtek Systems' access controller products are GIS compliant.

How do I configue a Gemtek Systems' access controller for a simple Hotspot service ?
