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:

a chassis including at least a front portion and a back portion, forming an enclosure;

a plurality of sectors defined within the enclosure, wherein the plurality of sectors each extend lengthwise with respect to the enclosure;

a plurality of card slots in each of the plurality of sectors, each card slot capable of hosting an RF module, wherein the plurality of card slots are arranged in rows, across the plurality of sectors, along the length of the enclosure;

at least one RF module in at least a first one of the plurality of card slots;

a switch module in at least a second one of the plurality of card slots;

PoE connectors between the switch and the plurality of card slots; and

a power source module in at least a third one of the plurality of card slots.

2. The transmission node of claim 1, wherein the RF module is a 2.4 GHz 802.11n and 5 GHz 802.11ac combined RF module.

3. The transmission node of claim 1, wherein the plurality of sectors comprises:

a first sector and a second sector; and

eight card slots, four card slots in each of the first and second sectors.

4. The transmission node of claim 3, further comprising:

at least two modules, the two modules being two RF modules of the same kind.

5. The transmission node of claim 4, 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.

6. The transmission node of claim 5, wherein the two RF modules are located in card slots located in different rows.

7. The transmission node of claim 1, wherein a module hosted in the plurality of card slots may be replaced.

8. The transmission node of claim 1, wherein the chassis is capable of dissipating heat.

9. The transmission node of claim 1, wherein the chassis is designed to be mounted on a pole such that a shape of the chassis matches the contour of the pole.

10. The transmission node of claim 1, wherein the plurality of card slots may be tilted 0°

to 10°

.

11. The transmission node of claim 1, further comprising:

at least one external PoE port, and

at least one external SFP port.

12. The transmission node of claim 1, wherein the plurality of sectors are arranged in parallel relative each other.

13. The transmission node of claim 1, wherein the modules lie flat in the slots.

14. The transmission node of claim 1, wherein the plurality of sectors are oriented at (180/(number of sectors))°

relative each other.

15. The transmission node of claim 1, wherein a cross-section of the chassis is arc-shaped.

16. A transmission site comprising:

at least one modular transmission node as described in claim 1; and

at least one backhaul.

17. The transmission site of claim 16, further comprising:

a camera, wherein the camera is connected to the transmission node.

18. The transmission site of claim 16,

wherein the backhaul is separate from the transmission node;

and

wherein a PoE connects the backhaul to the transmission node.

19. A local area network system comprising:

a controller connected to the internet;

a switch connected to the controller; and

a plurality of transmission sites, each transmission site comprising at least one modular transmission node as described in claim 1.

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

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

22. The local area network system of claim 19, further comprising:

a local area memory device, the memory device connected to the controller.

23. The local area network system of claim 19, 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.

24. The local area network of claim 19, wherein the at least one modular transmission node at each transmission site is mounted on a pole.

25. The local area network of claim 19, further comprising:

at least two cascaded modular transmission nodes at each transmission site.
