It’s Quite Easy to Assume that Deploying Wireless HSIA in a Hospitality MxU Environment Would Be
the Most Cost Effective and User-friendly Access Technology – If One Believes the Hype.
Read the facts.
|January 2004 - Paradyne’s customers face tough
decisions when deploying connectivity technology today and are choosing
infrastructure solutions. Installing BitStorm ADSL solutions provides for
your guest needs now and in the future.
It’s quite easy to assume that deploying wireless in a hospitality or residential MxU environment would be the most cost effective and user-friendly access technology – if one believes the hype. While many vendors have successfully hyped WiFi as the ultimate in connectivity, it is very important to understand the limitations of 802.11 technologies.
A Bluetooth device in a guests room will ‘hop’ frequencies trying to find one free of interference, but this action alone is likely to force the AP into an error state, at least until the Bluetooth device migrates out of the channel occupied by the WiFi access point. And while the Access point has ‘fallen back’ to some other data-rate in response to this interference, by design the AP will wait for some period of time before falling forward to the original transmission rate.
ADSL is the most widely deployed DSL technology in the world. ADSL is well understood, there are millions of lines deployed and provides the best price/performance of any broadband infrastructure technology. ADSL technology continues to be developed both in standards work and at the silicon level in order to meet the requirements to deliver future applications. The technology has evolved from the ADSL (8M bps) to ADSL2 (12M bps) and onward to ADSL2plus (26M bps).
ADSL is the go-forward technology being used to support HSIA, VOD and Broadcast Video around the world by Telco’s in outside plant and in-building deployments can take advantage of the higher bandwidths supported in these evolving ADSL solutions.
Deployment comparison for two broadband enabled properties
The following is a brief discussion of two theoretical scenarios; identical 200 room hotels, one deployed with ADSL and the second with Wireless. It can also be illustrated to the customer that ADSL technology is - today cost-competitive with correctly deployed WiFi only networks.
The owner of hotel A chooses to deploy network powered by Paradyne DSL. Each room has +/- 8mb data access capacity (dedicated). The DSL deployment is non-invasive to the structure of the building. Existing phone wiring is used to provide connectivity to each guest room and selected conference or meeting rooms. A brief visit to the guest suite is all that is required, with most of the work done at the head end – the telephone equipment room.
The owner of hotel B deploys wireless. A site survey is conducted for his property to determine the best placement locations for the access points. Using wireless access points with directional antennas it is determined that 15 access points will be required to provided radio coverage to the hotel and desired public areas. Hotel B’s access provider must contract to have CAT5 cable run to the access point locations, sometimes requiring boring through floors or walls. The cost of this work must be included in overall installed cost. Power injectors are used to supply power to the access point, so a 48v DC power supply is also required in the equipment room and represents another cost component. A 24 port Ethernet switch with VLAN and VPN support is installed. A properly designed wireless system costs more to install than first assumptions indicate.
So let’s evaluate usage scenarios at these two properties.
Laptop carrying customers of Hotel A can instantly connect their Ethernet enabled laptops (roughly 90% of business laptops sold have an integrated Ethernet adapter) to the network in their rooms.
Each room has access of up to 8mb/sec. to the shared T1 or DSL line installed for backhaul to the Internet.
At Hotel B the scenario is a bit different. Even with 13 million wireless access devices sold last year, home users far outnumber corporate users. Given this, those corporate users visiting the hotel will likely need to obtain a ‘bridge’ device from the front desk (an inventory / control problem for the hotel) and connect it to their Ethernet port. This device also requires a connection to the keyboard or mouse port and draws voltage from the users PC. A guest connected via the bridge device is not truly mobile = his hands are full with the equipment he must carry. And Federal employees will not even be able to use the network with these devices.
Nor is the network secure at Hotel B. A hacker
with a directional antenna can ‘snoop’ on the network in that hotel, and
with some effort break into a connected guest’s laptop. A dedicated ‘thief’
could actually spoof the hotels’ connect page, simply by copying it and
transmitting a stronger signal at the hotel than provided by the access
points, thereby obtaining credit card or other information from the unsuspecting
guest. Providing, of course, that there were sufficient guests in the hotel
using WiFi. M1, a Singapore telephone company, pulled out of WiFi hotspot
deployment in June 2003.
Now take these hotels and move forward a year.
Hotel A has had requests for wireless access in its restaurant and bar areas. An access point is deployed for less than $1000.00 to cover these spaces, and it is integrated into the VBN server so that guests may purchase access in the guest suite and still use the wireless sessions in the bar without having to pay again.
Hotel B wishes to deploy a next-generation Video on Demand system using an integrated IP network. This technology requires 6mb per each room - Hotel B must now deploy a separate infrastructure to each room to support this system.
Hotel A, in competition with Hotel B, chooses to deploy that same type of VoD technology with a Paradyne partner. The infrastructure exists and the product is deployed. Hotel A also integrates Energy Management systems over IP, and fully automatic Ethernet mini-bars in the guest suites. All of these services ride over the Paradyne ADSL network originally installed.
Of course, it is possible to assume that neither hotel will ever upgrade video technology or other service to the guest rooms. However, it is obvious from this illustration that the owner of Hotel A, by relying on a Paradyne partner, has effectively future-proofed his hotel by laying a foundation rather than simply deploying access-only technology.
And Hotelier A has not missed out on the ‘WiFi
boom’, he’s merely waited until there was sufficient demand to add what
the guests needed to the infrastructure Paradyne ADSL already provided.
For the customer, the deployment of ADSL technology provides an infrastructure that will ensure broadband service availability to every room in a hotel, or all apartments, even in a campus topology.
