Abstract

A local area network system that includes modular, multi-frequency, multi-channel, upgradable transmission nodes. The transmission nodes may include one or more independent RF modules and may be configured to include, for example, 802.11ac and may evolve to LTE and other technologies and frequency bands.

Claims

1. A transmission node having a modular structure comprising:

one or more card slots, each card slot capable of hosting a module;

a switch;

PoE connectors between the switch and the one or more card slots; and

a power source.

2. The transmission node of claim 1, wherein the module is an RF module.

3. The transmission node of claim 2, wherein the RF module is a 2.4 GHz 802.11n and 5 GHz 802.11ac combined RF module.

4. The transmission node of claim 1, further comprising six card slots.

5. The transmission node of claim 4, further comprising at least two modules, the two modules being two RF modules of the same kind.

6. The transmission node of claim 5, wherein three card slots are located in a first sector of the transmission node and three card slots are located in a second sector of the transmission node, the first sector and second sector each extending lengthwise with respect to the transmission node and being oriented at 90°

from each other.

7. The transmission node of claim 6, wherein one of the two RF modules is provided in a card slot located in the first sector and the other RF module is provided in a card slot located in the second sector.

8. The transmission node of claim 7, wherein each sector is subdivided into rows and only one card slot is located in each row of each sector;

and wherein the two RF modules are located in card slots located in different rows.

9. The transmission node of claim 1, wherein a module hosted in the one or more card slots may be replaced.

10. The transmission node of claim 1, further comprising a chassis.

11. The transmission node of claim 10, wherein the chassis is capable of dissipating heat.

12. The transmission node of claim 10, wherein the chassis is designed to be mounted on a pole.

13. The transmission node of claim 1, wherein the one or more card slot further comprise an attitude adjustment of 0°

to 10°

.

14. The transmission node of claim 1, further comprising at least one external PoE port, at least one external SFP port.

15. A transmission site comprising:

at least one modular transmission node; and

at least one backhaul.

16. The transmission site of claim 15, further comprising a camera, wherein the camera is connected to the transmission node.

17. The transmission site of claim 15, wherein the backhaul is separate from the transmission node;

and wherein a PoE connects the backhaul to the transmission node.

18. A local area network system comprising:

a controller;

a switch connected to the controller; and

a plurality of transmission sites, each transmission site comprising at least one modular transmission node.

19. The local area network system of claim 18, further comprising one or more backhauls connected to the at least one modular transmission node at each of the transmission sites.

20. The local area network system of claim 19, wherein the plurality of transmission sites are arranged in a loop.

21. The local area network system of claim 18, further comprising a local area memory device, the memory device connected to the controller.

22. The local area network system of claim 18, further comprising a camera at one or more of a plurality of transmission sites, wherein the camera is connected to the at least one modular transmission node located at the same transmission site as the camera.

23. The local area network system of claim 18, wherein the controller is connected to the internet.

24. The local area network of claim 18, wherein the at least one modular transmission node at each transmission site is mounted on a pole.

25. The local area network of claim 18, further comprising at least two cascaded modular transmission nodes at each transmission site.
