Answer up front: for an office building, business park, hotel, warehouse, factory, farm or large retail space across 1000m² for up to 100 users on mixed EE, O2, Vodafone and Three networks, the CW1000 at £685.00 is the pick; it pairs Band 20 at 800MHz 4G data with Band 1 at 2100MHz 3G UMTS data, voice and SMS on every network, cleans the donor with ≥70dB uplink / ≥75dB downlink gain — a +10dB step over the CW500's ≥60/≥65dB — keeps ≥20dBm output behind a ≤5dB noise figure, and ships the high-gain Yagi, 3dBi whip, 10m outdoor plus 5m indoor coax and UK plug. For a 500m² small office, cafe or large detached house for 50 users at ≥60/≥65dB with three antenna zones, the CW500 at £485.00 saves £200 on the same universal Band 20+1 plan and included Yagi. For an O2/Vodafone-only commercial site relying on legacy 2G calling, the CG1000 at £685.00 tunes Band 8 instead of Band 1.

The CW1000-versus-CW500 gap is a scale, gain and antenna-zone step, not a network change: both carry Band 20+1 and universal 3G, both ship the Yagi and both output ≥20dBm, but the CW1000 adds +500m² (1000 against 500), +50 users (100 against 50), the +10dB gain step (≥70/75 against ≥60/65, roughly ten times the amplification) and a fourth indoor antenna zone on a 4-way splitter. The CW1000-versus-CG1000 gap is a band choice at the same £685.00, same 1000m², same 100 users: Band 1 universal 3G versus Band 8 O2/Vodafone 2G, with the CW1000's higher gain and four zones.

This page compares the three Boost4U chassis side by side rather than in a roundup: the CW1000 at £685.00, the CW500 at £485.00 and the CG1000 at £685.00. It separates the shared Band 20 data layer from the two choices a buyer must make — how big the commercial space, how many devices, how far the mast (CW1000 vs CW500) and which fallback band (Band 1 universal 3G vs Band 8 O2/Vodafone 2G) — and gives a decision tree so the choice follows floor plan, headcount, donor distance and SIM mix.

All three are UKCA and CE certified, Ofcom licence-exempt, ship free within the UK on 1 to 2 day handling plus 10 to 15 day transit, and carry a 365-day mail return window. None carries 5G; the CW1000 and CW500 carry Band 1 3G, while the CG1000 carries Band 8 2G instead. All run from the AC 100–240V to DC 5V UK Type plug. The rest of this page numbers every band, £200 step and spec before you order.

Before the tables, three rules keep the comparison honest. First, Band 20 at 800MHz (uplink 832–862, downlink 791–821) is shared by all three and carries EE, O2, Vodafone and Three 4G data, so data capability is not the deciding factor between CW1000 and CW500; the deciding factor is scale, gain and antenna zones. Second, the CW1000 and CW500 add Band 1 at 2100MHz (uplink 1930–1990, downlink 2110–2180) for 3G UMTS data, voice and SMS on every network, while the CG1000 instead tunes Band 8 at 900MHz for O2/Vodafone 2G. Third, between CW1000 and CG1000 the price, area and users match, so that tie decides by fallback band, gain and zones; between CW1000 and CW500 the band plan, output and Yagi match, and the £200 decides by area, users, gain and fourth antenna.

Because the CW1000 and CW500 share the Band 20+1 plan, this comparison never turns CW1000 against CW500 on network coverage; it turns on whether the site fills 500m² for 50 users or 1000m² for 100, and whether a distant or obstructed donor needs the extra +10dB gain. A small office cannot use the extra 500m² and 50 users, so the CW500's £200 saving is rational; an office building, hotel or warehouse needs the CW1000's larger area, higher gain and fourth antenna zone.

Coverage figures assume reasonable donor signal outside and sensible antenna separation; the rated 1000m² covers an office building or multi-floor commercial space, and 500m² covers a small office, cafe or large detached house. On a strong −70 to −90dBm donor the CW1000 can feed up to 4 indoor antennas via a 4-way splitter and the CW500 up to 3 via a 3-way splitter; a weak −97 to −105dBm donor uses the included Yagi aimed at the nearest mast, with the CW1000's higher gain cleaning that donor more thoroughly. The tables below compare specs, the £200 step and day-one versus five-year cost before the decision tree.

Read the band row before the price row: CW1000 and CW500 share Band 1 universal 3G, CG1000 keeps Band 8 O2/Vodafone 2G; then read gain, scale, users and the antenna-zone row, where CW1000 adds 500m², 50 users, the ≥70/75dB gain step and a fourth zone over CW500, and matches CG1000 on scale while differing only in fallback band, gain and zones.

The £200 between CW500 and CW1000 buys area, users, gain and a fourth antenna zone, never a new network; the £0.00 tie between CW1000 and CG1000 buys a different fallback band and the higher gain rather than more scale. A buyer who stretches CW500 to an office building pays for a larger tier later, and a CG1000 buyer who later needs EE/Three fallback pays a Band 1 unit on top.

The CW1000 and CW500 share an identical band plan: Band 20 at 800MHz for EE, O2, Vodafone and Three 4G data, plus Band 1 at 2100MHz for 3G UMTS data, voice and SMS on every network. No network one covers, the other misses; both also output ≥20dBm and ship the high-gain Yagi in the full kit. The £200 difference exists entirely to serve more space, more devices, a weaker donor and a fourth indoor zone.

CW500: the 500m²/50-user business unit at £485.00

The CW500 reaches 500m² (5,382 ft²) for up to 50 users at ≥60dB uplink / ≥65dB downlink gain, ≥20dBm output, the included Yagi, 3dBi whip and 10m outdoor plus 5m indoor coax, with up to 3 indoor antennas on a 3-way splitter. It suits a small office, cafe, shop or large detached house where the active devices sit around three whips. Buyers here should not pay for an office building they never occupy.

CW1000: the 1000m²/100-user commercial flagship at £685.00

The CW1000 reaches 1000m² (10,764 ft²) for up to 100 users at ≥70dB uplink / ≥75dB downlink gain — a +10dB step over the CW500, roughly ten times the amplification — keeps the same ≥20dBm output and included Yagi, and supports up to 4 indoor antennas on a 4-way splitter. The extra gain cleans a distant or obstructed donor where a warehouse, factory or hotel sits behind metal cladding or multiple floors; the extra 50-user headroom keeps a meeting room, guest devices and warehouse staff from crowding one cell; the fourth zone reaches an upper floor or far aisle that a 3-antenna unit covers weakly.

The £200 step decides by floor area, headcount and donor distance, not by network

Because coverage band, output and donor antenna are identical, the CW500-versus-CW1000 choice is a pure sizing, gain and zone question: measure the commercial floor area, count active devices, and only pay £200 when the site genuinely fills 1000m², approaches 100 connections and sits far from the mast. A small-office buyer on CW1000 overpays for unused scale; an office-building buyer on CW500 gets a weak upper floor, a crowded fourth zone and insufficient gain for a distant mast.

The CW1000 and CG1000 tie on price, area and users, differing in the fallback band, gain class and antenna zones, because both share Band 20 for EE, O2, Vodafone and Three 4G data.

CW1000 Band 1: universal 3G for all four networks at high gain with four zones

The CW1000 tunes Band 1 at 2100MHz (uplink 1930–1990, downlink 2110–2180). On EE, O2, Vodafone and Three this provides a 3G UMTS data, voice and SMS fallback where 4G alone weakens, including MVNOs riding those networks, and the ≥70/≥75dB gain cleans that fallback across four indoor zones. It does not tune Band 8 O2/Vodafone 2G; a legacy 2G-only O2/Vodafone handset that cannot fall to 3G relies on VoLTE or its native network rather than a boosted 2G channel.

CG1000 Band 8: O2/Vodafone 2G only at class gain

The CG1000 tunes Band 8 at 900MHz instead, which carries O2 and Vodafone 2G voice calls and SMS, and 900MHz reaches deeper through masonry than higher bands. On EE and Three it provides Band 20 data only with no boosted call fallback; it never tunes Band 1 3G, and its gain and zone count follow a lower class than the CW1000's ≥70/75dB and four whips. The CG1000 is the right box when the commercial SIMs are O2/Vodafone-led and legacy 2G calling matters to those two networks only.

The £0.00 tie decides by call path and donor gain, not by scale

Because price, coverage and users are identical, the CW1000-versus-CG1000 choice is a pure fallback question: mixed-network office, hotel or warehouse needing universal 3G across four zones with a distant donor = CW1000; O2/Vodafone-only commercial site needing legacy 2G = CG1000; mixed where both Band 1 3G and O2/Vodafone 2G matter = no single chassis solves both, and a band-specific second unit is required rather than forcing one box.

Walk the branches top to bottom and stop at the first yes.

Branch 1 — Does the property fill roughly 1000m² across floors of an office building, hotel, warehouse, factory or large shop, with up to 100 active phones, laptops and guest devices?

Yes: scale belongs on the flagship CW tier rather than the 500m² CW500; move to Branch 2 for the band question. No: under 500m² for 50 users, jump to Branch 4.

Branch 2 — Is the mast distant or the donor obstructed by masonry, metal cladding or floors, and do the SIMs mix EE, O2, Vodafone and Three?

Yes: the ≥70/75dB high gain, the universal Band 1 3G layer and the fourth antenna zone matter, so choose the CW1000 at £685.00, Band 20+1, 1000m², 100 users, ≥70/75dB, Yagi included, 4 zones. No and all SIMs are one network with a clean donor: move to Branch 3.

Branch 3 — Are all SIMs O2/Vodafone-led and do the handsets rely on legacy 2G rather than VoLTE or 3G?

Yes: CG1000 at £685.00, Band 20+8, O2/Vodafone 2G calls, accept EE/Three data-only at class gain. No (modern VoLTE phones, mixed networks, distant mast, need four zones): stay with the CW1000's Band 1 universal fallback and high gain.

Branch 4 — Is the job a small office, cafe, shop or large detached house under 500m² for about 50 users on a mixed-network Band 20+1 plan with three antenna zones and a clean donor?

Yes: CW500 at £485.00, same universal Band 1 3G and included Yagi on the smaller scale at ≥60/65dB, save £200. No and the site grows beyond 500m²: return to Branch 1 for the CW1000.

Branch 5 — Do you need 5G, a multi-building estate beyond 1000m², more than 100 users, or both Band 1 3G and Band 8 2G at once?

Yes: a £485.00 or £685.00 single-fallback commercial unit is undersized or band-wrong; choose a larger multi-antenna or band-specific system. No and the site fits 1000m²: return to Branch 1, 3 or 4 and order the matched unit.

Day one, the CW1000 and CG1000 tie at £685.00; the CW500 sits £200 below at £485.00. The five-year total separates a correctly matched commercial flagship from a late step-up or second band.

The CW500 buyer who later moves to an office building or multi-floor hotel steps up a tier rather than stretching a 500m² unit; the CG1000 buyer who later adds EE or Three devices pays a Band 1 unit on top of the £685.00 already spent. Only the correctly matched single CW1000, CW500 or CG1000 closes the job day one; over-buying CW1000 for a small office wastes £200, while under-buying CW500 for an office building forces a second purchase.

The CW1000 box at £685.00 holds the booster, the high-gain Yagi directional aerial, the 3dBi whip indoor antenna, the UK power adapter, the 10m outdoor low-loss coax, the 5m indoor coax and a mounting bracket; paid variants are 20/30/40/50m external cable and the 18KA protector. On a strong −70 to −90dBm donor, a 4-way splitter and extra coax feed up to 4 indoor antennas across floors; a weak −97 to −105dBm donor uses the included Yagi aimed at the nearest mast, where the ≥70/75dB gain does the cleaning. The CW500 box mirrors the cable stack at £485.00 with a 3-way splitter, and the CG1000 box mirrors the cable stack for Band 8.

Basic setup takes 10 to 15 minutes without tools: mount the Yagi with a clear mast view, keep the whip a sensible distance inside, run the outdoor and indoor coax, power from the UK plug, and read steady green before testing across floors. The expansion note reads "Expandable coverage by adding indoor antenna, splitter, cable if the outside signal is strong."

All three carry UKCA, CE and RoHS, are Ofcom licence-exempt, ship free within the UK (handling 1–2 days, transit 10–15 days), and carry a 365-day mail return window. The £685.00 CW1000 price is valid to 2027-10-22, InStock NewCondition, and ships to GB, DE, FR, IT, ES, NL, BE, AT, SE, DK, FI, IE, PT, PL and CZ; the CW500 at £485.00 and CG1000 at £685.00 follow the same shipping and return terms.

Office building, business park, hotel, warehouse, factory, farm or large retail filling 1000m², up to 100 mixed-network devices, universal 3G across EE/O2/Vodafone/Three with a distant or obstructed donor and four indoor zones fed by ≥70/75dB gain: CW1000 at £685.00, Band 20+1, the only chassis that pairs universal Band 1 with this scale, high gain and a fourth antenna zone.

Small office, cafe, shop or large detached house under 500m² for 50 mixed-network users with a clean donor and three zones: CW500 at £485.00, Band 20+1, save the £200 you never use.

O2/Vodafone-only commercial site on legacy 2G at 1000m²: CG1000 at £685.00, Band 20+8, accept EE/Three data-only at class gain.

Quick verdict: the CW1000 and CW500 speak the same universal Band 1 language at the same ≥20dBm and with the same included Yagi, with the £200 difference buying 1000m², 100 users, a +10dB gain step and a fourth antenna zone rather than a new network; the CW1000 and CG1000 cost the same and match on scale, so there the Band 1 versus Band 8 call path decides — pick CW1000 for mixed-network 3G at high gain with four zones, CW500 for small business, CG1000 for O2/Vodafone 2G only.
