The Gettysburg Address, The Space Needle, Harry Potter, Southwest Airlines, great Beatles’ songs, Kathrein Canister Antennas – What do these all have in common? Well, the title gives it away- they all had their start with brilliant people brainstorming and sketching on cocktail napkins!
Kathrein just released the latest in a long line of canister small cell antennas. The Ultra-High Band, 10 port omni canister antenna 84010555 supports 2, 3.5, and 5.8 GHz frequencies, and provide operators and neutral hosts with a small cell solution that is future ready (more on this later). Let’s first explore a brief history of canister antennas and how Kathrein set the standard for innovation and aesthetics.
2004: The Canister Makes its Debut
In wireless years, 2004 was an eternity ago, but that is when ExteNet Sytems approached Kathrein about building a DAS (distributed antenna system). At a quaint restaurant in Medford, Oregon, Kathrein’s Rick Veghte and Jim Dekoekkoek (both engineers) sat with Tormod Larsen, CTO from ExteNet Systems, and came up with the original sketch and plans for a brown canister, quasi-omni antenna.
They used internal parts from existing Kathrein panel antennas, while outsourcing the high quality, fiberglass radomes from a local manufacturer. The initial concerns were that the nuls would be too deep and that there would be a lot of multipaths. Rick and Jim went to work designing the prototype, and were pleased that the canister achieved the stringent electrical performance that both companies expected. Manufacturing began within a couple months.
The original canister had 4 ports (2 high-band, 2 low-band). In 2010, Kathrein began selling canisters to operators as small cell antenna solutions. Due to the compact design, the canisters fit perfectly on telephone and utility poles, and blended into the environment. Since then, Kathrein has continued to add ports and extend frequencies while trying to maintain the same form factor. Due to sheer physics this is not an easy engineering feat.
2017 and Beyond – The Race to Gigabit Data Speeds/5G
While a widely accepted definition of 5G is still being worked out, there is a race among operators to deliver gigabit data speeds, and claim that they are the first to offer “5G”. The current macro system won’t allow for this kind of speed. Operators will need to tap into shared spectrum – 3.5 GHz and 5 GHz bands (Ultra High-Band) so they can stitch together enough spectrum (carrier aggregation) to offer gigabit speeds to subscribers. There are of course challenges with unlicensed bands (wi-fi) in that they are often crowded and have rules of usage, such as “listen before talk.”
In response to market demands, Kathrein has just released two new canister antennas: the 84010555 (brown) and 84010556 (grey) are the solution for operators that want to tap into ultra-high band frequencies as they prep for 5G.
The new Kathrein canisters:
- Support 2, 3.5, and 5.8 GHz
- Utilize the same form factor: no rezoning required
- Support 4×4 and 2×2 MIMO
- Support 4 ports at 1695-2690 GHz, 4 ports at 3.5 GHz, and 2 ports at 5.8 GHz
Kathrein Canister Antennas have a long history of industry leading innovation, quality, and performance. The latest ultra-high band canisters can easily replace existing canisters, providing operators with a future proof small cell solution in the race to 5G.
